Voiced in English by: Bill Sullivan (Ultra Galaxy Fight: New Generation Heroes), Jim Foronda (Ultraman Z)

The son of the Father and Mother of Ultra, Ultraman Taro is the sixth and youngest of the iconic Ultra Brothers (Zoffy, Ultraman, Ultraseven, Ultraman Jack, and Ultraman Ace) who has trained as a warrior since he was just a boy. He merged with a young man named Kotaro, who was revived by the Ultra Brothers when he was killed trying to battle Astromons. Ultraman Taro has gone on to become one of the most important Ultra heroes in the franchise, as he trains newer heroes in the Land of Light, has appeared as a major character in other series, and even had his own movie. Taro would later become the father of Ultraman Taiga in the Reiwa Era.

---

• Action Bomb: The Ultra Dynamite, one of his most well-known secondary abilities, allows him to become this. He reforms afterwards, but it costs a huge amount of his Colour Timer energy.
• Action Dad: He's the father of Ultraman Taiga, one of the first Reiwa Ultras.
• Badass Cape: By the time Ultraman Mebius came along, the Showa Ultramen back in M-78 began wearing long flowing capes. The change was confirmed in Mega Monster Battle: Ultra Galaxy Legends.
• Bash Brothers: With Ultraman Ace, who is actually his adopted brother.
• Calling Your Attacks: The first Ultra in the series to do this.
  "STORIUM KOUSEN!"
• Finishing Move: The Storium Ray; notable for being done in a T-shape, rather than the typical "L" or "+" shape.
• Hand Blast: Like most Ultras, he can fire various lesserbeam attacks from his hands.
• Horn Attack: Able to shoot lightning from his horns. Often used to blow off monsters' body parts in close combat.
• Horned Humanoid: Inherited from his dad, one of the few Ultramen with horns.
• Meaningful Name: Taro is a popular name for the protagonists of Japanese fairy tales, and as Tsuburaya considers Ultraman Taro to be the fairy tale of the franchise, it was chosen for the series' hero.
• The Mentor: In later Ultra series, as his job back in the Land of Light is to train new Ultra warriors. Notable pupils of his are Ultraman Mebius and Ultraman Ginga.
• Momma's Boy: He dearly loves his mother and respects her teachings.
• Power Glows: When unleashing his Storium Kousen, Taro will glow entirely in a series of rainbow-coloured lights, a trait which is carried over to his future appearances in the series.
• Rookie Red Ranger: In his own series, in which he was considered this among the Ultra Brothers. He's matured quite a bit since then.
• Swiss-Army Weapon: The King Bracelet, which he first got from his mother to defeat Birdon.
• Uncanny Family Resemblance: Bears several of Ultraseven's traits, such as shoulder armor, a head lamp, and identical-looking eyes. Officially, this is because Seven is his cousin.

Mother of Ultra

Mother of Ultra

Voiced by: Peggy Hayama (Ultraman Taro; also human form actor), Masako Ikeda (Ultraman Story and Ultraman Mebius), Rie Hasegawa (Mega Monster Battle: Ultra Galaxy Legends), Miki Ohtani (Ultraman Ginga onwards)

Ultrawoman Marie, the wife of the Father of Ultra and the literal mother of Ultraman Taro. The Mother of Ultra (or Ultra Mother) is the chief of the Land of Light's Silver Cross Corps — the Space Garrison's medical division. She is a powerful healer, but also regularly drops advice and combat assistance for her son and husband when necessary.

---

• Action Mom: She aids Taro in his titular series and briefly held her own against Belial.
• Aliens Among Us: She is one of several Ultras who takes on a human form instead of a host, appearing as a kindly middle-aged woman known only as "the Lady in Green" if she wishes to speak to Kotaro.
• Badass Cape: Similar to her husband, she too dons a red cape to reflect her status.
• Big Good: For Taro, as Taro's mother and the one who gives him guidance throughout. For the franchise as a whole, she and the Ultra Father form a Big Good Duumvirate.
• Cool Old Lady: She's the grandmother of Ultraman Taiga.
• Combat Medic: She's the matriarch of the Silver Cross Corps and fought in the Ultimate Wars.
• Happily Married: By all accounts, her marriage to Father of Ultra is a happy one.
• Lady of War: See Combat Medic.
• The Medic: Acts as one for the Ultra Brothers, with her powers going up to revival of the recently deceased.
• The Mentor: For Taro in his own series.
• Number Two: As her husband is the Father of Ultra, Supreme Commander of the Space Garrison, she is only second to him in importance in the organization.
• Special Person, Normal Name: Her real name is Marie, according to Mega Monster Battle: Ultra Galaxy Legends.
• Team Mom: Plays this role for the Ultra Brothers, and is literally one for Taro.

The Ultra Brothers

The Ultra Brothers

"Roku kyoudai!" - L - R: Zoffy, Ultraman, Ultraseven, Taro, Jack, Ace.

Much like the previous show, the Ultra Brothers make a comeback as well, this time with "Six Ultra Brothers" being coined by the franchise as the go-to term for referring to the first six Showa-Era Ultramen.Ultraman Taro is also the show which the iconic "Six Brothers" theme ("Urutora Roku Kyōdai") made it's debut, and for the first time, audiences get to see all six of them working in tandem to defeat the Monster of the Week. Notably Alien Temperor, and then to fetch the Ultra Bell to counter Mururoa, and in The Movie, Ultraman Story, battling the powerful juggernaut monster Grand King.

---

• All Your Powers Combined: The six brothers pooled their powers in order to defeat Alien Temperor in the two-parter, and later to retrieve the Ultra Bell.
• Combination Attack: They tend to perform these in tandem with Taro.
• Continuity Nod: In the Alien Temperor two-parter, the original Ultra Brothers have to "borrow" the bodies of several MAT staff as hosts in order to observe their youngest brother, Taro, in combat. Their merging with hosts is depicted as a semi-transparent, ghost-like form of their Ultraman bodies descending into their hosts - the exact same manner as Ultraman Jack merging with Hideki in the pilot of Return of Ultraman.
• A Death in the Limelight: Zoffy, in the second part of the Birdon three-parter, while defending a hospital. Don't worry, he gets better thanks to the Mother of Ultra.
• Heroic Sacrifice: Don't worry, Death Is Cheap.
  • Ultraman Zoffy gave up his life holding back Birdon, in order to prevent the monster from destroying a hospital. He lost, but he managed to drive the monster away before his death, and Taro came back in time - resurrected - to challenge Birdon on a rematch.
  • Ultraman Jack offering his Color Timer to Dorobon, in exchange for the life of ZAT Deputy Captain Kazumi. He gets his Timer back on a few minutes later, but still...
• Let Me at Him!: During the second episode of the Alien Temperor two-parter, the Ultra Brothers, Taro included, are having a party in their human forms, and Taro (who had defeated Alien Temperor on his own via bursting out of the alien's stomach) boasts that his training is complete, he's more than prepared to face whatever incoming threats and his brothers can "spare him the pep talk". As the oblivious Taro (as Higashi) cheerfully walks away, an enraged Ace (as Hokuto) flies in a rage and angrily tried lashing out, only for Jack (as Hideki) to restrain him.
• Squashed Flat: The fate of poor Ultraman Jack after having his Timer ripped off.
• The Worf Effect:
  • Unfortunately, the brothers end up becoming various Worfs when the nigh-unstoppable monster, Tyrant, which is created by the collective hatred of the Ultra by various kaiju, arrives to challenge them. They end up being taken down one by one - Ultraman on Uranus, Seven on Saturn, Jack on Jupiter, and Ace on Mars - but the moment Tyrant reaches Earth to battle Taro, Taro emerged the winner.
  • Zoffy himself suffers this trope when he gets defeated, and outright killed, by Birdon in the middle of a three-parter. Though to be fair, taking Birdon in a head on fight ended just as bad for Tarou as it had Zoffy, and Zoffy actually managed to hurt Birdon, which Tarou hadn't been able to. Also, Zoffy made a trip back to M-78 to drop Tarou off, then came back to fight Birdon.

Monsters and Aliens

Introduced in Ultraman Taro

Oil Drinker

First Appearance: The Ultra Mother is Like the Sun

The very last of Yapool's Choju to attack Earth (for the time being), targeting oil rigs for both sustenance and destruction. However, the monster soon met its end when a greater threat emerge to ZAT in the form of Astromons, who devoured the unfortunate Choju.

---

• Breath Weapon: Breathes fire.
• Did You Just Punch Out Cthulhu?: When it first appeared Kotaro managed to use a mechanical crane to scare it off.
• Expy: Its design was based on Garan from Ultraman Ace.
• Noun Verber: Oil Drinker does pretty much exactly Exactly What It Says on the Tin.
• Sea Monster: It's an aquatic Choju that attacks oil rigs and tankers.
• Spell My Name With An S: Sometimes called Oilmons.
• The Worf Effect: The idea behind Oil Drinker being consumed by Astromons was to demonstrate that the new generation of kaiju in Ultraman Taro would be far more powerful and dangerous than the Choju of Ultraman Ace.

Astromons

First Appearance: The Ultra Mother is Like the Sun

A strange flower that Kotaro had discovered during his sailing years and brought home to Japan to grow. Unfortunately, the flower was the sprout form of Astromons, which quickly grew into its mature form to rampage through Tokyo and attack both ZAT and Oil Drinker. Given Astromons’ ability to keep up with and defeat Oil Drinker, the monster is the first ‘Super-Ability Monster’, a class of Kaiju applied to several other monsters in this series, including Cosmo Liquid, Live King, Depparas, Rodera, Rindon, Mukadender and Mururoa.

---

• Acid Attack: Can spray an acidic mist from the giant flower on its belly.
• Breath Weapon: Although it never does this in the show, Word of God has stated that Astromons is able to breathe fire.
• Create Your Own Villain: Kotaro himself planted the flower allowing Astromons to be born.
• Foul Flower: Begins as an extraterrestrial flower called a Tigris Flower that Kotaro had discovered during his world trip. The flower on its chest is all that remains when it grows up, and it is able to devour other creatures and spray acid.
• Hook Hand: Astromons' left arm is a giant hook-shaped appendage.
• Make Way for the New Villains: Easily disposes of Oil Drinker, showing that the kaiju in this show will be a greater threat than the Choju of the previous show.
• Metamorphosis Monster: First appears as a giant flower that sprays knockout pollen and has bloodsucking vines, but eventually grows to full size...and in the middle of ZAT dealing with Oil Drinker's rampage.
• Mix-and-Match Critters: Its mature form resembles a dinosaur mixed with a flower.
• Starter Villain: Although not the first kaiju encountered in the series, it is the first opponent of Ultraman Taro.
• Swallowed Whole: Does this to Oil Drinker via the flower on its stomach — an homage to Bemstar from Return of Ultraman, whose suit Astromons was created from.

Cosmo Liquid

First Appearance: This Time, It's the Ultra Mother

A man-eating monster with the ability to transform into liquid, which made it a serious pest for ZAT to hunt down and attack. Things got even worse with the awakening of Live King, resulting in a three-way battle once Ultraman Taro joined to try and get rid of both monsters.

---

• Achilles' Heel: Due to the fact that Cosmoliquids is composed out of water, electricity is particularly harmful to it and will force Cosmo Liquid to take on its normal form if in liquid form.
• Elemental Shapeshifter: Can transform into water, allowing it to slink through rivers completely undetected and strike at human targets without warning.
• Literally Shattered Lives: ZAT destroys Cosmo Liquid by smashing it with a spiked wrecking ball after Ultraman Taro freezes both him and Live King.
• Mêlée à Trois: Engages in one with Ultraman Taro and Live King.
• Overly-Long Tongue: Cosmoliquids' main weapon, which it uses to snatch human prey.
• Spell My Name With An S: Also called Cosmoliquids.
• Sore Loser: when Live King knocks him down he starts throwing a fit as Live King continues to laugh at him.
• To Serve Man: Likes to eat humans.

Live King

First Appearance: This Time, It's the Ultra Mother

Voiced by: Osamu Saka

A jovial monster with a big belly and an even bigger appetite that was awoken from underground by the scuffle between Ultraman Taro and Cosmo Liquid. Live King proved to be an even bigger nuisance than Cosmo Liquid in the resulting three-way battle, thanks to its potent regenerative abilities.

---

• Beware the Silly Ones: Easily one of the goofiest kaiju ever created, but Live King sure gave Taro and ZAT a tough time! It took the intervention of the Mother of Ultra to finally kill the damn thing.
• Big Eater: Even while still regenerating, the monster consumes an entire henhouse!
• Breath Weapon: Breathes fire.
• Die Laughing: Kept doing his booming laughs even while exploding!
• Exposed Animal Bellybutton: Has a very prominent navel that ZAT punches a hole through to free Kotaro and Kenichi when they get swallowed by the monster, not that it seriously injures Live King.
• Fat Bastard: Although his jolly personality and big belly would make him seem like an example of Big Fun, the fact that Live King's a destructive giant monster means he's this trope instead.
• From a Single Cell: Live King can regenerate within a matter of hours upon death as long as there is oxygen surrounding it, which made it a colossal annoyance to kill.
• The Hyena: His "roars" are a series of hearty laughs, rather than the psychotic giggling common to other laughing kaiju like Gan Q.
• Mêlée à Trois: Engages in one with Ultraman Taro and Cosmo Liquid.
• Not Quite Dead: Despite being blown to pieces by Taro it manages to regenerate good as new the next day.
• Our Monsters Are Weird: Pot-bellied, duck-faced kaiju that constantly guffaws and regenerates as long as there is oxygen. Definitely one of the less normal kaiju in the Ultra Series, but an excellent introduction to the zaniness that is Ultraman Taro.
• Psychopathic Manchild: Gives off this vibe with its constant laughter especially when it's devouring its prey.

King Tortoise and Queen Tortoise

Left: King Tortoise
Right: Queen Tortoise

First Appearance: Giant Sea Turtle Monsters Attack Tokyo

A mated pair of turtle monsters that lived on an island off the coast of Japan, protecting their eggs from intruders. However, they went on a rampage when greedy human smugglers stole their eggs and ate them, as the enraged parent monsters became determined to destroy the interfering humans at all costs.

---

• Breath Weapon: Both monsters can spit bombs from their mouths. King Tortoise's act like standard aerial bombs, while Queen Tortoise's are Sticky Bombs.
• Combination Attack: They do much of their fighting together and protect each other at all costs, often using combo abilities.
• Expy: To Seamons and Seagoras, a kaiju couple who only wants to find their own mating grounds, and works in tandem when they're forced to defend themselves. However, the Tortoises are portrayed in a much more sympathetic manner.
  • Also, a tortoise monster that flies by spinning. Sound familiar?
• Humans Are the Real Monsters: Both King Tortoise and Queen Tortoise had lived completely in peace until a gang of unscrupulous poachers came and took all of their eggs to be sold and/or eaten, making the human criminals the only real villains in the conflict.
• Mama Bear / Papa Wolf: They are furious when the humans begin to mess with their nest and attack them for it.
• Monster Is a Mommy: The Tortoises are solely interested in avenging their eggs when the smugglers eat them, only to be further enraged by the JSDF's hostility towards the monsters. Even Ultraman Taro starts feeling bad for them after Queen Tortoise is killed.
• Non-Malicious Monster: Their rampage was completely justified by what the humans did to them. So Ultraman Taro decides to spare them and find them a new homeworld instead, although Queen Tortoise never lives to see it.
• Roaring Rampage of Revenge: Their motivation was to kill every last human responsible for stealing and destroying their eggs, even if they had to trash all of Tokyo in the process.
• Spin Attack: King Tortoise can retract into their shells and spin vertically opposite of each other to create a vortex of energy that traps foes in it.

Mini Tortoise

First Appearance: Parent Star, Child Star, First Star

The son of King and Queen Tortoise who hatches from their sole surviving egg during the giant sea turtle monsters' climactic showdown with Ultraman Taro, ZAT, and the JSDF in the middle of Tokyo, leading to a major turn of events in the massive battle between the monsters and the humans.

---

• Gentle Giant: He's a completely peaceful monster, and he refuses to participate in his parents battle against Ultraman Taro, ZAT, and the JSDF.
• Make My Monster Grow: Mini Tortoise is only the size of a human when he hatches, so King Tortoise fires a beam from his head to increase his height to 42 meters.

Jirenma

First Appearance: Jewels are the Monster's Fodder

A slug-like monster from Egypt that appeared Japan due to the powers of a cursed necklace that Kotaro had brought back home from his sailing years. Kotaro gave the necklace to Saori as a gift, unaware of its cursed properties, which soon resulted in her home being terrorized by the monstrous mollusk.

---

• Breath Weapon: Can spray an acid from its mouth capable of dissolving a building.
• Energy Absorption: Jirenma begins as a tiny creature, but when it absorbs a beam from Kotaro's ray gun, it metamorphoses into its giant form.
• Extra Eyes: Have at least four, two on it's head and two more on eye-stalks. Which leads to....
• Eye Scream: Taro rips off Jirenma's eye-stalks in the peak of battle.
• Implacable Man: It will stop at nothing to get the necklace back whether it be tearing down buildings or killing anything in its way.
• Kick the Dog: Literally. It kills the Shiratoris' pet dog Pochi when it first appears.
• Logical Weakness: Jirenma's highly-acidic breathe is strong enough to subdue even Ultraman Taro, but then ZAT deduce that they could counter the acidic properties with alkalic solutions. Cue a ZAT jet assisting Ultraman Taro by unleashing a powerful dose of alkalic spray all over the Ultra, allowing Taro to No-Sell all of Jirenma's attacks and turn the battle around.
• Make My Monster Grow: Kotaro unintentionally does this when he fires his ray gun at Jirenma making it a giant monster
• Overly-Long Tongue: Which Jirenma uses to try and strangle Ultraman Taro during their fight.
• Sealed Evil in a Can: A giant monster whose default form is a harmless-looking necklace.
• Spell My Name With An S: Also called Dilemma.
• Tongue Trauma: While it attempts choking Ultraman Taro with it's tongue, Taro instead uses his horn beams to sever it. And then grab the stump to execute a kaiju hammer throw on Jirenma.

Ganza

First Appearance: Heaven and Hell Island Has Moved

A crab-like monster that smashed ships off the coast of Japan and eluded detection quite successfully. However, when ZAT showed up to search for the creature, they instead found a very unusual island that, after landing on it, seemed to be moving...

---

• Breath Weapon: Breathes an acidic mist that coalesces into foam on impact.
• Detachment Combat: It can remove its claws and fire them like rockets at its enemy.
• Female Monster Surprise: After Ultraman Taro kills Ganza, hundreds of large crabs scuttle out of its corpse, which the narrator explains are the creature's young. The baby crabs then get fished up and eaten by locals, which we can only hope prevented an outbreak of Ganzas from occurring later on.
• Giant Enemy Crab: So giant that ZAT mistook it for an island when they found it sleeping and decided to land on it for a nice little rest.
• Power Pincers: Ganza can launch its pincers as missiles and regenerate them in an instant.
• Sea Monster: Of the crustaceous variety, complete with wrecking ships down the coastlines.
• That's No Moon: ZAT mistakes the sleeping monster as a floating island. Tt's only when Tagarl shows up that the monster awakens.

Tagarl

First Appearance: Heaven and Hell Island Has Moved

An octopus monster that appeared shortly after ZAT located Ganza (and discovered they had literally been standing on the creature for several hours). Tagarl does battle with the crab monster but is swiftly defeated and sinks back into the waves, never to be seen again.

---

• Breath Weapon: Squirts ink from its nozzle-like mouth.
• Butt-Monkey: Solely appears to have its butt whooped by Ganza.
• Eye Scream: Ganza pierces out one of Tagarl's eyes during the battle, forcing the monster to retreat.
• Giant Squid: An octopus kaiju.
• Sea Monster: Of the cephalopod variety, complete with a Behemoth Battle with another sea monster.
• We Hardly Knew Ye: Tagarl solely appears in a single brief fight scene and disappears just as quickly once Ganza defeats it. However, it does finally alert ZAT to why Heaven and Hell Island has moved several hundred meters from where they originally spotted it.

Tondaile

First Appearance: Dead Spirits of the Man-Eating Marsh

A toad-like monster that haunted a marsh feared by the locals due to rumors of man-eating spirits inhabiting the place (created by the monster's ability to conjure Hitodama Lights). It captured humans by creating frogspawn-like capsules to store them for later eating.

---

• Amphibian at Large: It's a giant toad kaiju.
• Breath Weapon: Breathes fire. Additionally, Tondaile's transparent capture orbs are spat from its mouth, though they only seem to work on human-sized opponents.
• Eye Scream: One of Tondaile's eyes gets poked out by the human characters tossing a knife into it.
• Hitodama Light: The source of these in the swamps it lives in, creating legends of man-eating spirits.
• To Serve Man: Tondaile captures humans by spitting out frogspawn-like capsules that imprison any victims they hit so the monster can store them in is lair for later eating.

Arindo

First Appearance: The Day that Tokyo Crumbles

Rat-sized, fire-breathing ants capable of chewing through steel and concrete, which they used make skyscrapers crumble and leave ZAT scratching their heads despite sightings by Kenichi and his friends. They later merged into a kaiju in order to destroy the rest of Tokyo.

---

• Big Creepy-Crawlies: They're a colony of ants so big that Kenichi and his friends could hear then chewing from inside the buildings they nested in. Then there's their singular kaiju form, which draws inspiration from winged drones.
• Breath Weapon: In both kaiju and normal form, Arindo breathes fire. The kaiju version also breathes acid.
• Eat Dirt, Cheap: The Arindo ants consume steel and concrete, making them sorta like termites for an urbanized metropolis with disastrous results for Tokyo's skyscrapers.
• Fusion Dance: To battle Ultraman Taro, the Arindo ants transform themselves into a kaiju by merging together.
• The Juggernaut: Arindo was completely unfazed by the Storium Ray, which forced Ultraman Taro to introduce audiences and the monster to his mighty Ultra Dynamite.
• Metal Muncher: They eat steel.
• Shock and Awe: Arindo electrocutes Taro by channeling electricity down its antennae when the hero attempts to rip them off in the fight.

Depparas

First Appearance: The Fang's Cross is the Monster's Grave

A walrus-like monster from the Arctic that came to Japan to satisfy its love for ketchup. ZAT dispatched it quite easily when it initially arrived, but unfortunately for them, Depparas quickly returned from the grave as a much more powerful and ferocious zombie with vengeance in mind.

---

• Breath Weapon: Breathes fire.
• Non-Malicious Monster: Starts off as one due to simply being interested in finding food, but after ZAT kills it, the zombie proves to be much more vengeful.
• Our Zombies Are Different: Comes back as a zombie to continue its rampage and avenge its first death at the hands of ZAT.
• Pulling Themselves Together: ZAT kills Depparas with no help from Taro in their initial encounter with the monster, only for its body parts to reassemble themselves into a zombie.
• Trademark Favorite Food: Depparas loves to eat ketchup, which is why it came to Japan in the first place.
• Tunnel King: Traveled to Japan from the Arctic by burrowing underneath Tokyo once it reached dry land.
• Weapon Tombstone: As the episode title implies, Taro erects a grave in its honour by using its tusks as a makeshift cross after he kills it permanently.
• Wily Walrus: A walrus-based kaiju able to shoot its tusks like missiles and revive itself from the dead.
• Woobie, Destroyer of Worlds: An innocent creature whose only crime was that it really wanted ketchup, is killed by ZAT and comes back as a zombie to claim vengeance on humanity.

Basara

First Appearance: The Bloodsucking Flower is a Young Girl's Spirit

A bloodsucking plant monster composed of the flowers growing on the grave of a dead little girl in the cemetery near Kotaro and the Shiratoris' home. It took on the form of the cluster of ivy vines and flowers growing on said gravestone to attack humans without being spotted.

---

• Foul Flower: It was spawned from the vampiric flowers growing on a little girl's grave. Unfortunately, another young girl thought the flowers were beautiful and decided to spread them around as gifts.
• Kill It with Fire: How Taro kills it.
• Man-Eating Plant: Drinks human blood by stretching out vines from the flowers and ivy that make up its mass in search of victims.
• Our Vampires Are Different: Basara is a mass of ivy and flowers manifesting from the grave of a little girl (as the episode's title suggests, the girl's ghost spawned the monster), giving the monster a thirst for blood.

Volkellar

Sheltar

First Appearance: The Monster's Cavity Hurts!

A marine monster that lived off the coast of Kyushu, where it was content with just keeping to itself and eating fish. However, it was driven to the surface in agonized rage when ZAT tested a missile near its home, only for said weapon to get wedged in the monster's teeth.

---

• Breath Weapon: Breathes fire.
• Non-Malicious Monster: Sheltar was purely just going crazy from the pain of having a missile stuck in its teeth, and is otherwise a peaceful creature. That doesn't stop ZAT and Ultraman Taro from killing the kaiju anyways after they removed the missile from its teeth.
• Sea Monster: Liked to hide on the seafloor away from humans until ZAT accidentally pissed it off with a botched missile test.
• The Tooth Hurts: Sheltar's entire story revolves around this, as the creature has an agonizing cavity from a missile wedged in its teeth. ZAT proceeds to make things worse when they accidentally pull out the wrong tooth while trying to help it.

Enmargo

First Appearance: Taro's Head Got Chopped Off!

A fearsome oni samurai that was defeated centuries ago by a Buddhist monk whose statue kept the monster imprisoned within a cliffside. Unfortunately, a greedy development company that cared little for local beliefs released Enmargo in the present when they removed the statue.

• Breath Weapon: Breathes a poisonous smoke that kills vegetation in seconds, but takes longer to affect living creatures.
• Deus ex Machina: a well written example. Enmargo manages to cut Taro's head off but the Buddhist monk's statue is returned and is able to reverse the effect, reattaching Taro's head and cutting off Enmargo's head.

A nine-tailed Kitsune monster that was responsible for killing the mother of a shunned young girl named Kaoru several years ago. It returned in the present to use its fiery magic tricks to deceive Kaoru by impersonating the ghost of her dead mother to lure her to her doom.

---

• Asian Fox Spirit: Based on the kitsune, even though it doesn't look much like one.
• Breath Weapon: Breathes fire.
• Invisibility: One of its favorite abilities to confuse enemies.
• Kick the Dog: Many years ago it killed Kaoru's mom, traumatizing her.
• Master of Illusion: As a Kitsune kaiju, it possesses the ability to conjure hallucinations, such as those of Kaoru's deceased mother.

---

• Gonk: Okariyan is considered by many fans to be the ugliest monster in the entire Ultra Series, due to how cartoonish it looks compared to other Ultra creatures.
• Nose Nuggets: Okariyan's main power is the explosive boogers that it expels from its nostrils as it pleases.
• Our Monsters Are Weird: The living curse of a magical flute in the form of one of the goofiest-looking kaiju ever. Ultraman Taro's like that.
• Super-Senses: Okariyan can pinpoint the sound of its cursed flute from anywhere, thanks to its supreme hearing.
• The Tooth Hurts: Ultraman Taro smashes the monster's buck teeth during the fight.

Kemujira

First Appearance: Two Giant Monsters Close in on Taro

Prehistoric insect monsters that had been awoken by the eruption of Mt. Okuma. They proceeded to attack the local summer watermelon farmers and eat their watermelons, with one managing to grow to full size. However, as ZAT and Ultraman Taro soon discover, the Kemujira were not the real threat...

---

• Big Creepy-Crawlies: Loosely based on caterpillars, which is more evident in Kemujira's larval form than in the fully grown kaiju.
• Breath Weapon: Breathes a sticky webbing that can blind humans for long periods.
• Curb-Stomp Battle: It is quickly killed and devourered by Birdon showcasing how much stronger its predator is.
• Food Chain of Evil: Kemujira's presence was enough of a worry for ZAT, but then its predator Birdon had to show up...
• Gasshole: During the fight, Taro gets Kemujira's head stuck between two buildings and it retaliates by farting in Ultraman Taro's face! It tries the same tactic on Birdon, but the predator simply uses its wings to blow the gas away.
• Gigantic Adults, Tiny Babies: The mature Kemujira stands 47 meters tall, but as a larva, they're small enough to hide inside a watermelon.
• Poisonous Person: Kemujira has a poisonous stinger in its mouth that can paralyze enemies.
• Prehistoric Monster: The Kemujira larvae were awoken by the same volcano that Birdon was awoken by.
• Spell My Name With An S: Kemujira or Kemjila?
• Trademark Favourite Food: The Kemujira larvae love the taste of watermelon. They initially hide in some watermelons, eating them from the inside and attacking people who cut them open.

Birdon

First Appearance: Two Giant Monsters Close in on Taro

A prehistoric avian monster that had been slumbering in volcanic Mt. Okuma until it was awoken by the same eruption that awoke Kemujira. However, it only became known to ZAT when it appeared to battle Kemujira and Ultraman Taro, easily killing both of them (and later Zoffy), leaving ZAT all alone to defeat the seemingly unstoppable kaiju.

Being the only monster of the Showa era series to have a Multi-Part Episode that ran for three parts and one of the most infamous Hero Killers in the Ultra Series, Birdon has become Ultraman Taro's most iconic enemy, scoring it regular returns in the franchise. Worth noting is that Birdon's infamous beak stabbing was reworked in later appearances into being venomous.

---

• Achilles' Heel: Birdon's sac-like wattle (venom sacs in later series) is its most vulnerable point.
• Arch-Enemy: Of Kemujira, its preferred prey.
• Beak Attack: Birdon kills Ultraman Taro and Zoffy by stabbing them to death with its beak. In later series, this was retconned into being venomous, though it still remains lethal.
• Blow You Away: Like many flying kaiju, Birdon's enormous wings can be used to create hurricane-strength gusts of wind.
• Breath Weapon: Able to breathe a stream of fire.
• Breakout Villain: As Ultraman Taro's most iconic enemy, Birdon has appeared in nearly all entries since it returned in Ultraman Mebius.
• Expy: Of Rodan, both being flying prehistoric monsters that hatch from a volcano. even its connection with Kemujira mirrors that of The Meganulon, with the latter being insectoid kaiju that are seen as the main threat before the former comes in and devours them all, taking the spot swiftly and keeping it for the remainder of their screentime. Birdon is also defeated by getting thrown inside a volcano, though it's never stated to have been killed and was merely sealed back. Later series also have Birdon showing fire powers, not unlike Rodan shown in the following installments.
• Family-Unfriendly Violence: The stabbing of Zoffy and Taro, which features grievous wounds on the characters' corpses.
• Feathered Fiend: A very fiendish one if you're not prepared.
• Female Monster Surprise: ZAT discovers eggs in its volcano nest and quickly work to destroy them to prevent another Birdon from emerging.
• Food Chain of Evil: The predator of Kemujira and far more dangerous than it, as Ultraman Taro and Zoffy learned the hard way.
• Giant Flyer: Like all bird kaiju.
• Hero Killer: Of both Taro and Zoffy! Which is the reason why Birdon is so popular in the first place. Not even the infamous Zetton has killed that many Ultramen.
• The Juggernaut: The fact that the damn thing took three episodes to defeat it in its debut is a testament to its durability. Ultraman Taro doesn't even kill it in the end! The only thing he can do is seal it back inside the volcano it originated from.
• Knight of Cerebus: In a show as cartoonish as Taro, Birdon stands out as a truly serious threat. Nothing about it is played for laughs, ZAT treats the situation much more seriously than they usually do, many of its scenes involve eating people and it straight up kills Taro and the previously undefeated Zoffy.
• Lightning Bruiser: Incredibly fast flyer (Mach 10) and also a very strong monster.
• Mêlée à Trois: Engages in this with Kemujira and Taro, although neither of its opponents is much of a match for it.
• A Molten Date with Death: Subverted: Ultraman Taro seemingly destroys Birdon by tricking it into crashing into an active volcano, which then erupts and seals it for good, but it turns out to be in hibernation.
• Playing with Fire: Being a volcano monster, Birdon can breathe fire and is immune to extreme heat, being able to swim in magma.
• Prehistoric Monster: A giant bird sealed away in a volcano.
• To Serve Man: After eating all the Kemujira, Birdon turns to humans to satisfy its hunger after ZAT stops the production of other meat sources in Japan.
• Villainous Glutton: Its huge appetite for meat causes it to devour Kemujira, attack all sources of meat in Japan, and go after humans once ZAT stops all the meat production in an attempt to stop its attacks.
• The Worf Effect: Killing Zoffy, one of the most powerful Ultra warriors.

Raidron

First Appearance: Surprise! A Monster Came Falling Down!

A baby bird monster from outer space that got close to Earth in order to observe fireworks from a Japanese summer festival. Unfortunately, its wing was injured by the aforementioned pyrotechnics, leaving it stranded on Earth and helpless without its mother who could only watch in distress from space.

---

• Breath Weapon: Can spit explosive energy bolts.
• Gentle Giant: Raidron is a peaceful kaiju. The baby was injured by fireworks and scared by ZAT's attacks on it (they worried that its presence would endanger the nearby summer festival and sought to drive it away) while the mother is powerless to do anything.
• Giant Flyer: Even the baby Raidron is the same size as Ultraman Taro.
• Non-Malicious Monster: The baby Raidron is on a rampage while searching for it's mother, rather than attacking humans on purpose.
• Shock and Awe: Can shoot lightning from their crest feathers.

King Zemira

First Appearance: Tokyo Newtown Sinking

A cicada that had been slumbering underneath an apartment complex for countless years, turning giant-sized from pollution seeping underground. While the creature did not seek to bother humanity, its awakening and cacophonous buzzing was a major annoyance for Tokyo.

---

• Attack the Mouth: He's defeated when it's tube-like mouth gets chopped off by Ultraman Taro.
• Big Creepy-Crawlies: An ordinary cicada that grew to a gigantic size, but is otherwise content to live its life the same way a normal-sized cicada does.
• Breath Weapon: Breathes fire, as well as webbing.
• Cicadian Rhythm: The same as a normal cicada, except at kaiju-sized. So while the creature is completely harmless, its buzzing was even more annoying for the people of Tokyo.
• Humans Are the Real Monsters: The entire episode is a commentary on humanity's tendency to destroying nature for being a minor annoyance. It's doing nothing wrong but humanity attacks it because it's making loud noises.
• Giant Flyer: Since normal cicadas can fly as well.
• Meaningful Name: "Zemi" is Japanese for "cicada", making it the king of cicadas.
• Non-Malicious Monster: King Zemira is simply just an oversized insect in terms of behaviour and motives, only attacking Tokyo when ZAT attacks it (even then the team only attacked the creature because locals demanded they do something after getting annoyed by its droning). For this reason, Ultraman Taro spares the monster's life and brings it to space to find a new planet for the creature to live on.

Pandora

First Appearance: Wrath of the Child-Carrying Monster

A peaceful kangaroo-like monster that hails from a subterranean world and came to the surface in search of food. The creature was content to be left alone eating trees, but ended up going on a rampage due to its joey Chinpe being targeted by a human hunter.

---

• Beneath the Earth: It's stated Pandora came from some kind of underground environment (although its exact nature is never expanded on), but made its way to the surface in its quest for food.
• Breath Weapon: Breathes fire as well as toxic gas.
• Gentle Giant: Pandora is content to be left alone and eat trees as long as humans don't try to harm Chinpe.
• Mama Bear: The reason why Pandora has to battle Ultraman Taro is that the monsters goes berserk after Chinpe is wounded by a hunter.
• Monster Is a Mommy: Of Chinpe, of course, whose injuries at the hands of a human were the reason for its rampaging.
• No Good Deed Goes Unpunished: Helps a human who fell down a cliffside to recover, this ultimately leads to a party searching for her, to shoot at it and nearly kill its kid.
• Tail Slap: Likes to use this in the battle against Ultraman Taro.

Chinpe

First Appearance: Wrath of the Child Carrying Monster

Pandora's human-sized joey, which normally spends its time in its mother's pouch, but decided to explore its surroundings while Pandora was busy. The friendly creature who was targeted by an arrogant hunter but befriended by both Kotaro and the hunter's girlfriend (who opposed his love of killing animals).

---

• Gigantic Adults, Tiny Babies: Chinpe is about the size of a human, whereas its mother stands over 50 meters tall. However in real life, kangaroo joeys start their lives extremely small, at the size of a jellybean. For comparison, the largest kangaroo species, the Red Kangaroo, stands nearly the size of a man.

Rodera

First Appearance: Gentle Daddy Monster

A strange monster able to spew a unique form of acid that only dissolves steel from its trunk-like nose. Rodera's unusual ability made it of interest to a greedy but foolish wife who wanted to use the monster's powers to make a profit off disposing abandoned cars.

---

• Acid Attack: A variant. Rodera is able to shoot out an acid from its nose that eats through steel in seconds, but is otherwise harmless. It can also create a tornado of the stuff for extra destruction.
• Detachment Combat: Can split off into multiple pieces and fly around
• Eye Scream: Get's a pointed bamboo pole shoved into it's eye by Kotaro.
• Gonk: Another Ultraman Taro critter noted by many for being incredibly ugly due to its extremely cartoonish design. One reviewer described it as a mix of Gigan and a garden pail.
• Hand Blast: Can fire a powerful stream of energy from both its hands.
• Money Spider: A non-video game example; after Taro blows up Rodera, it then drops hundreds and hundreds of toy cars all over the city's streets, much to the delight of children everywhere.
• Our Monsters Are Weird: Another incredibly goofy-looking Ultraman Taro critter, with big ears, a big nose, eyestalks, fins on its back, and cone-like projections on its torso.
• Pulling Themselves Together: As Ultraman Taro finds out, Rodera is able to reform if its body is chopped into pieces.
• Shock and Awe: Able to grab enemies to electrocute them.
• Tunnel King: Burrowed about underneath a highway, using its steel-dissolving tornado to wreak havoc unseen.

Mururoa

First Appearance: This is the Land of Ultra!

A monster from outer space whose presence on a planet clouds the world in black, light-destroying smoke. Released by accident from an asteroid by an Earth missile, Mururoa's deadly powers forced Ultraman Taro to head for the Land of Light to retrieve the legendary Ultra Bell to counter its abilities.

---

• Allegorical Character: With a name derived from a nuclear test site and its light-destroying Atomic Fog covering the world in darkness, Mururoa is likely intended to personify the effects of a nuclear winter.
• Beware the Silly Ones: Despite Mururoa's design being among the silliest in a series full of ridiculous-looking kaiju, the monster was treated as an ender of worlds, and certainly lived up to it as it could cloak entire planets in a darkness so great that Ultraman Taro had to retrieve the Ultra Bell, one of the most powerful artifacts in the Land of Light, to dispel the stuff.
• Breath Weapon: Breathes acid.
• Casting a Shadow: Mururoa hates light and destroys it by producing tons of smoke to blot out the Sun.
• Macabre Moth Motif: Its design motif is based on moths.
• Meaningful Name: Named after Moruroa, an atoll in French Polynesia which was the site for French nuclear testing, referencing how it was set free by a space missile being tested by ZAT.
• Sealed Evil in a Can: Had been imprisoned inside an asteroid for untold millennia until a space missile being tested by ZAT blew up the prison, setting Mururoa free.
• Weakened by the Light: It hates light and produces its Atomic Fog to counter this.

Space Moths

First Appearance: This is the Land of Ultra!

Hordes of large extraterrestrial moths that herald the appearance of Mururoa. Having been sealed in the same asteroid as Mururoa, they assist the monster is destroying light sources by searching for light and using their enormous numbers to smother it out.

---

• Herald: Of Mururoa They actually lead the monster to planets for light to snuff out, as they're attracted to the very thing Mururoa seeks to destroy.
• Moth Menace: These are giant alien moths whose appearance heralds the arrival of a monster that destroys all light on any planet it arrives on.

Rabbidog

First Appearance: This is the Land of Ultra!

Ultraman Taro's pet dog-like creature back on M78. It only appears very briefly to greet Ultraman Taro upon his arrival to the Land of Light (shown and detailed in its fullness for the first time in the Ultra Series) to retrieve the Ultra Bell needed to defeat Mururoa.

---

• Canine Companion: The Ultra equivalent of one for Taro.
• What Happened to the Mouse?: He's never really ever been seen again after his brief greeting of Ultraman Taro when the hero arrives at the Land of Light. A manga reveals that Alien Temperor killed him during the events of his two-parter.

Alien Empera

First Appearance: Burn On! The Six Ultra Brothers!

A being mentioned in a flashback exposition on the history of the Land of Light. He appears only as a shadowy figure encircled in a red sphere behind an army of kaiju, which he used to invade M78 long ago. He'll become more important in a future series...

---

See Ultraman Mebius

• Chekhov's Gunman: Who would have ever guessed back in 1973 that a character introduced solely for the purpose of fleshing out the Land of Light would go on to become one of the franchise's biggest Big Bads?
• He Who Must Not Be Seen: Only appears as a silhouette behind his kaiju army◊, and would remain as such for the next 30-something years.

Mukadender

First Appearance: I Can Conquer a Monster Too!

A bizarre centipede-like monster that suddenly appeared to terrorize Japan during a village's summer festival, intent on finding humans to consume. Although not one of Taro's most famous foes, Mukadender has reappeared a couple more times in the Ultra Series, notably Ultraman Mebius.

---

• Achilles' Heel: Its head feels whatever its body experiences and vice versa, meaning hurting the head will hurt the body. In a more bizarre manner, throwing the head into the air will cause the body to fly too, which is exactly how Taro defeats Mukadender!
• Breath Weapon: Two actually — a stream of fire and a spray of immobilizing webbing.
• Creepy Centipedes: A little difficult to tell at first due to its reptilian appearance, but its Boss Subtitles is "Centipede Monster".
• Losing Your Head: Its primary trait. Whenever Mukadender's head is torn off its body, both parts remain animate and can act on their own will.
• Meaningful Name: "Mukade" is Japanese for "centipede".
• Our Monsters Are Weird: More than one person has pointed out the Freudian placement of Mukadender's head, although its more intended to invoke the monster's tail and head having switched places.
• Spell My Name With An S: Mukadender or Mukadendar?
• To Serve Man: Likes to eat humans, particularly in Ultraman Mebius.

Mandarin Grass

First Appearance: He's Back! It's Alien Mefilas!

---

• Healing Factor: Able to regenerate its vines if they're torn off. It can also produce a chemical which is an antidote to its own poison, and also has regenerative properties if applied to injuries.
• Poisonous Person: The vines of the Mandarin Flower are covered in stingers that inject a paralyzing poison into those that it attacks.

Alien Mefilas II

What happens when Mefilas skips leg day.

First Appearance: He's Back! It's Alien Mefilas!

Voiced by: Ikuo Nishikawa

The first of a handful of monsters and aliens from previous series brought back in an attempt to alleviate sagging ratings. This second Alien Mefilas commanded the monster Mandarin Flower from hiding to attack unsuspecting people before eventually deciding to step out and battle ZAT and Ultraman Taro himself.

---

See Ultraman TV Series

• Art Evolution: The Mefilas in this series is taller and skinnier than normal, with pink rims around his eyes, a different-shaped "mouth", and a golden belly. Justified by the fact that he's a different individual from the original Alien Mefilas.
• Curb-Stomp Battle: Was on the receiving end of one, dished out by Taro. His attacks barely have any impact on the Ultra, and he gets taken down in less than 40 seconds!
• Eye Beams: An ability not seen in any other version of Alien Mefilas since.
• Eye Scream: Prior to fighting Taro, he gets one of his eyes shot out by ZAT, forcing him to use the Mandarin Grass's healing properties to repair the damage.
• Long-Lost Relative: Some children's magazines claim that this Mefilas is the brother of the one from Ultraman.
• Torso with a View: Taro punches a hole straight through his gut in the fight.
• The Unfettered: Doesn't believe in fair play at all.
  "There is no difference in being despicable or honorable!"
• Villain Decay: Alien Mefilas loses a lot of his menace and cunning from his original appearance, becoming a run-of-the-mill invader who relies on a plan revolving around a giant flower that eats people by hiding in a vending machine. He proceeds to get curbstomped by Taro after Mandarin Flower is destroyed.

Eleking

First Appearance: Monster Eleking Howls at the Moon

The second classic monster brought back in this series. This is the original Eleking mysteriously resurrected by some unknown power, recreating it as a fire-breathing monster that awakens every night to rampage before returning underground at daybreak to sleep.

---

See Ultraseven

• Aim for the Horn: Much like the original, this Eleking had both it's horns pulled off by Taro in battle, causing it to become unstable before exploding. This time Taro took the horns away from earth to prevent Eleking's resurrection.
• Art Evolution: Eleking is now a dark yellow with a thicker tail and a darker mouth. His antennae no longer rotate either.
• Back from the Dead: It's not exactly clear in the show exactly how Eleking came back to life, but a children's magazine from the period states that a malevolent alien was behind the resurrection.
• Continuity Nod: Eleking was revived in the exact same village it was killed by Ultraseven, 6 years ago.
• Lunacy: For this instance only, Eleking's resurrection powers are caused by absorbing light from a full moon.
• Playing with Fire: For some reason, this version of Eleking can shoot fire from its mouth and tail instead of the usual electric powers. Somewhat justified by the fact that Eleking's role was originally intended for a mammoth-based kaiju called Gokiba, who was replaced at the last minute because it was decided Eleking would bring in better ratings.

Yapool

First Appearance: Bemstar Resurrected! Taro's Absolute Sacrifice!

Voiced by: Hirofumi Takada

The next veteran Ultra monster brought back to save the show's ratings is none other than the Big Bad of Ultraman Ace, who has returned piloting a spacecraft for revenge against the Ultras by resurrecting the classic kaiju Bemstar as a Choju to defeat Ultraman Taro and ZAT, plus two of his own creations, Velokron and Sabotendar. This appearance notably made concrete Yapool's nature as being able to eternally resurrect himself due to the grudge he holds over the Ultras, a trait which has been retained throughout his subsequent appearances.

---

See Ultraman Ace

• Art Evolution: More accurately, "Art Devolution". Yapool has a shabbier appearance in this series as the producers recycled the "Giant Yapool" suit from Ultraman Ace, which had deteriorated quite a bit since its first appearance.
• Villain Decay: Yapool's completely reduced to sitting in a spaceship and using a staff to call forth old creations of his before eventually getting destroyed along with his monsters.

Bemstar

First Appearance: Bemstar Resurrected! Taro's Absolute Sacrifice!

Yet another classic Ultra kaiju brought back the producers to attract more viewers. This is the original Bemstar from Return of Ultraman resurrected by Yapool in a new and improved Choju form, proving itself to be an even deadlier foe than in its original appearance.

---

See Return of Ultraman

• Alien Blood: Bemstar bleeds yellow blood, as seen when Umino manage to land a few stabs into its eye.
• Art Evolution: Due to the fact that the original Bemstar suit had been recently modified into Astromons before being turned back into the new Bemstar, this version of Bemstar lacks a beak and has small red eyes.
• Back from the Dead: This is the original Bemstar battled by Ultraman Jack, now resurrected by Yapool and modified into a Choju.
• Colossus Climb: In the second battle, Umino managed to cling himself onto Bemstar using a rope attached on the monster's horn, and from his vantage point, repeatedly stab Bemstar in the eye.
• Eye Beams: This version of Bemstar possesses these powers.
• Eye Scream: Umino, a friend of Kotaro manages to jab the monster's eye out when he manages to climb onto its face.
• It Only Works Once: When Bemstar first appears on Earth, ZAT tries to attack it with a giant circular saw that's supposed to have the same cutting power as Ultraman Jack's Ultra Bracelet, which originally cut Bemstar to pieces. When they finally connect, though, the saw just gets mangled, and Yapool mocks ZAT for thinking that he wouldn't learn from its previous defeat.
• Poisonous Person: Bemstar can now spew toxic gas from its Belly Mouth as well.

Sabotendar

First Appearance: Counterattack! The Monster Army!

One of two Choju to be brought back in this series. This version of the cactus monster is in fact the original Sabotendar resurrected by Yapool to assist Bemstar for the final showdown against Ultraman Taro. However, it was quickly defeated by the horned hero.

---

See Ultraman Ace

• Art Evolution: Sabotendar's costume is not the same as the one used in Ultraman Ace, so the suit has a less detailed appearance, longer spikes, as well as being a brighter shade of green.
• Butt-Monkey: Solely appears to get his butt whooped by Ultraman Taro.

Velokron

First Appearance: Counterattack! The Monster Army!

The second of two Choju from the previous series brought back for this one. This is the second Velokron brought back to life by Yapool to assist Bemstar alongside Sabotendar. However, the monster was swiftly dispatched by ZAT's firepower.

---

See Ultraman Ace

• Art Evolution: This is the only instance in which Velokron's second design was used over its original one, but even then there are a few differences from the one that appeared in Ultraman Ace, notably that Velokron is a greener colour.
• Butt-Monkey: Despite being lauded as reinforcements by Yapool, Velokron is easily destroyed by ZAT's aircraft.

Mushra

First Appearance: Danger Lying! Poisonous Mushrooms

Voiced by: Ikuo Nishikawa

A monster that first appeared in the form of a gigantic toadstool, but was quickly destroyed by ZAT. However, a piece survived and tricked a boy with a "plant-language translator" named Daisuke into bringing it to a water source that it infected to turn all of Tokyo into mushroom-headed zombies.

---

• Breath Weapon: Breathes acid.
• Festering Fungus: Mushra infects water, so that anyone who drinks it turns into a Mushroom Man that it can control.
• From a Single Cell: Mushra's default giant mushroom form attacks the city right at the start of the episode and is killed almost instantly by Ultraman Taro. But a single spore escaped and gains a life of it's own.
• Fungus Humongous: Mushra is essentially meant to be a kaiju-sized spoof of the Matango.
• Kill It with Fire: Ultraman Taro defeats Mushra by setting the monster on fire, causing it to lose the water it needs to sustain itself.
• Metamorphosis Monster: It initially appears in the middle of the city as a gigantic mushroom that ZAT destroys quickly, but a piece of it survives to trick a kid into taking it to a water supply to regenerate into its complete form.
• Poisonous Person: Mushra's toadstool head leaks out a potent green venom capable of destroying buildings.
• The Virus: Mushra spreads a contagion through water that turns others into mushroom people, turning all of Tokyo into an Ultraman Taro-styled Matango. This can be reversed by destroying Mushra.

Guron

First Appearance: A Nipping Wind Monster! Matsuboroh of the Wind!

A strange windbag monster that creates great gusts of wind by simply just breathing in and out. It attracted the interest of an oddball boy named Don Matsuboroh, who is implied to be connected to the creature in some way, given the fact that he is more fond of Guron than he is of Taro.

---

• Blow You Away: By breathing in and out, Guron creates gusts of wind that can reach hurricane levels if it inhales a sufficient amount.
• Casting a Shadow: Can turn itself into a shadow to avoid detection.
• Cyclops: Have a single red eye, which is its sole facial feature besides its mouth.
• Inflating Body Gag: Courtesy of Ultraman Taro plugging Guron's mouth with the King Bracelet, which made its body inflate as it floats comically into the air.
• Living Gasbag: It's main inspiration.
• Oculothorax: A kaiju version.
• Our Monsters Are Weird: It's a giant one-eyed windbag kaiju!
• Red Herring: It ultimately turns out that Don Matsuboroh has no unusual relationship with Guron. He's just a weird kid and nothing more.

Alien Temperor

First Appearance: Five Seconds to the Big Explosion of the Land of Ultra!

Voiced by: Eiji Maruyama

One of a race of wicked aliens who had waged war with the Ultramen centuries ago, Alien Temperor came to Earth with his subordinate, another member of his kind, to destroy the Ultra heroes by fighting and harassing the six Ultra Brothers in their human forms and out of them while his spaceship resurrected him whenever necessary.

As his appearance marks the first time all the main Ultra hosts are seen onscreen together, Alien Temperor has become one of Ultraman Taro's best-known foes. For this reason, he has reappeared numerous times in the Ultra Series. As he's also the closest opponent in the series to a main antagonist, Temperor's race also has more appearances than almost any other alien introduced in Ultraman Taro, significantly overshadowing Alien Valky, the actual final opponent in the series. Temperor also received a redesign to go with his kind's reappearances, giving the alien a more sinister appearance.

---

• Agony Beam: One of Temperor's many attacks fired from his pincers is an orange energy beam designed to torture victims.
• Arc Villain: Of episodes 33 and 34.
• Badass Cape: It's strong enough to act as a shield, and in Ultraman Mebius, it can transform into a pair of wings.
• Blinded by the Light: Can fire explosive flashes of blinding light from his pincers.
• Breakout Villain: Temperor has appeared very frequently since his return in Ultraman Mebius (where he received his visual update), due to being among Ultraman Taro's most iconic foes.
• Death Is Cheap: The main reason why he put up such a challenge for the Ultra Brothers was that every time they killed him, his spaceship would fly in and resurrect him!
• Eat Me: Taro kills his subordinate by flying into his mouth and making him explode from the inside out.
• Insectoid Aliens: Designed to look like Alien Baltan of Ultraman fame.
• Lightning Lash: Alien Temperor can generate electrified whips using it's pincers, which he uses to great effect lashing out at the Ultra Brothers. This ability is one of Temperor's trademark abilities, which is carried over in his subsequent appearances in movies and video games.
• Name To Run Away From Really Fast: Temperor's name is a combination of "tyrant" and "emperor", as he was originally intended to be the alien who would eventually be developed into Alien Empera, Big Bad of Ultraman Mebius, 36 years later.
• Playing with Fire: Can shoot fire from his pincers.
• Poisonous Person: Temperor can spray toxic gas from his antennae tubes.
• Power Pincers: Temperor's pincers can create a huge variety of attacks from standard energy bolts to blinding flashes to streams of fire to electric whips. Appropriately, they're called Omni Pincers.
• Shock and Awe: Can shoot lightning from his pincers.
• Spell My Name With An S: Temperor or Tempeler?
• Voluntary Shapeshifting: During the two-parter, he turns himself into a spider to torment Kotaro.

Alien Katan

First Appearance: Certain Kill! Taro's One Blow of Rage!

Voiced by: Ikuo Nishikawa

An evil alien who blinded Ultraman Taro during his first battle with the horned hero. He used the subsequent opportunity to try and assassinate the hospitalized Kotaro by taking over the body of a young Ultraman-loving girl named Machiko, so that nobody would suspect a thing.

---

• Demonic Possession: As part of his scheme to incapacitate Ultraman Taro and Kotaro, Katan takes over the body of a young girl named Machiko so that no one will ever suspect him.
• Eye Beams: He uses these to blind Ultraman Taro, but otherwise they're incapable of doing any other damage.
• Playing with Fire: Can shoot streams of fire from his palms.
• Would Hurt a Child: In order to take over Machiko's body, Katan crashes a car into her.

Grost

First Appearance: "Coward!", The Bride Cried

An icy alien who made himself known only a handful of hours after Ultraman Taro had defeated Alien Katan, meaning Kotaro was still blinded from the earlier events. He had taken over a construction site and enslaved the workers there with his mind control powers in order to organize his invasion scheme in secret.

---

• Achilles' Heel: Obviously, Grost is weak to extreme heat, which also nullifies his mind control powers.
• Breath Weapon: Breathes freezing mist.
• Hidden in Plain Sight: Grost's disguise is a wall ornament, one that is somewhat unusual-looking. Kohtaro didn't even realize he's in the same room as Grost until the alien reveals himself.
• An Ice Person: As his frosty appearance and name indicate, Grost hails from a freezing planet and possesses a number of ice-based powers.
• Mind Control: As part of his scheme to conquer Earth, Grost hides out in a building still being constructed and mind controls the workers as his slaves. Unfortunately, one of the workers' girlfriend had a younger brother who caught on to what was going on.

Hertz

First Appearance: Monster, Return to Your Homeland!

A friendly monster who arrives on Earth fleeing a war on his home planet being waged by the evil Alien Medusa. While ZAT is unsure about what to do with the peaceful creature, Alien Medusa comes to Earth to kill Hertz by any means necessary, including trying to convince ZAT that it was evil.

---

• Breath Weapon: Officially, Hertz is stated to be able to breathe fire, but he never demonstrates this in the show.
• Gentle Giant: Hertz really doesn't cause any problems when he arrives on Earth and only seems to wander about the countryside minding his own business. Unfortunately, Alien Medusa is trying to goad ZAT into killing the monster.

Alien Medusa

First Appearance: Monster, Return to Your Homeland!

Voiced by: Ikuo Nishikawa

A hideous and wicked alien who comes to Earth in pursuit of Hertz. Rather than carrying out the act of killing the peaceful creature by herself, she tries to goad ZAT into killing the gentle monster through various schemes, most notably disguising herself as a woman and claiming the creature killed her grandfather.

---

• Demonic Possession: Takes over the body of Moriyama in order to try kill Hertz by using ZAT's vehicles and weaponry.
• Dirty Coward: She doesn't have the guts to carry out killing Hertz or fighting ZAT, instead relying on deceit and sabotage until she is finally forced to fight Ultraman Taro.
• Hate Sink: A ruthless, manipulative alien who is also a compulsive liar, claiming that the harmless Hertz is a vicious monster who killed her grandfather. Despite being a monster of some great power, Medusa is mostly a coward, relying on taking over ZAT's equipment rather than risk exposing herself to danger.
• Manipulative Bitch: Medusa does anything she can to have ZAT kill Hertz, including taking on the form of a young woman named Megumi and accusing the monster of killing her grandfather when it arrived on Earth (while there was an old man in a state of unconsciousness, Medusa had just knocked him out to justify her accusations).
• Meaningful Name: While Medusa doesn't look anything like the Gorgons of Greek myth, it's meant to be indicative of her hideousness (her Boss Subtitles is "Ugly Alien").

Alien Miracle

First Appearance: The Ultra Christmas Tree

Voiced by: Dai Nagasawa

A friendly owl-like alien who comes to Earth to spread Christmas cheer. He befriends a girl named Hitomi who had been orphaned in Taro's battle with King and Queen Tortoise, and gives her a magic crystal ball to remind her of the Christmas spirit. Unfortunately, the malicious Alien Terrorist murders him not long afterwards.

---

• Bird People: His design motif is an owl.
• Crystal Ball: His gift to Hitomi, which allows those who look into it to see the past and present, as well as their deepest desires. It's also through the same globe does Hitomi see Miracle get killed by Terrorist.

Alien Terrorist

First Appearance: The Ultra Christmas Tree

---

• Fangs Are Evil: A ruthless and cruel invader with two massive fangs from his jaw.
• Hand Blast: Able to shoot organic missiles from his fingertips.

• Master Swordsman: His weapon of choice is a giant sword, and he's pretty good with it.
• Names to Run Away from Really Fast: Terrorist sounds like a friendly guy, doesn't he?

Mochiron

First Appearance: Ultra Father's and Son's Big Mochi-Making Strategy

Voiced by: Takeshi Watabe

A curious mortar-like monster from the Moon who loves to eat mochi rice cakes. In fact, Mochiron loved mochi so much that he came down to Earth during the Japanese New Year festival in order to eat all of the mochi in Japan!

---

• Big Eater: Of mochi, of course! So much that he threatened to consume Japan's mochi supply in a matter of days.
• Breath Weapon: Breathes fire.
• Cool and Unusual Punishment: For eating all the mochi in Japan and causing a lot of havoc in the process, Mochiron's fate is to help Taro, the Father of Ultra, and Yuko make mochi for the people of Japan by being used as a mortar.
• Non-Malicious Monster: Mochiron doesn't want to hurt people, only eat mochi, but his appetite and misbehaviour force the Father of Ultra and Yuko Minami to come down from the Moon and help Taro subdue the mochi-eating monster.
• Our Monsters Are Weird: A mochi-eating tiki-mortar monster from the Moon!
• Rolling Attack: By retracting his limbs into his body, Mochiron can roll about like a giant log to squash his enemies.

Tyrant

First Appearance: Go Beyond the Ultra Brothers!

A chimera formed from the vengeful spirits of Red King, Alien Icarus, Bemstar, Seagorath, Barabas, Hanzagiran, and King Crab merging themselves together to destroy the Ultra Brothers. Tyrant made a beeline for Earth to battle Taro while defeating each of the Ultra Brothers one by one.

One of the most popular kaiju in the Ultra Series for his formidable power and striking hybrid design, Tyrant has made many reappearances in the franchise as among the Ultra heroes' most powerful and dangerous of their regular Monster of the Week foes, befitting of the fearsome reputation he had in his debut.

---

• Achilles' Heel: His own weapons are strong enough to harm him, as demonstrated by Taro.
• All Your Powers Combined: As you'll quickly see from the list of tropes for this guy, almost all of his abilities are borrowed from the monsters his parts are formed from.
• Belly Mouth: Borrowed from Bemstar, but with a few new powers added.
• Breakout Villain: Tyrant became one of the most popular and iconic of Ultraman Taro's foes very quickly, thanks to its incredible strength and power, thus reappearing against many subsequent Ultra heroes.

• Epic Flail: Taken from Barabas' left hand.
• Grappling-Hook Gun: In its Barabas flail, an ability of the Choju it was taken from.

• An Ice Person: Can shoot freezing gas from its Bemstar gorge.
• The Juggernaut: Defeated a total of five Ultramen without breaking a sweat, and was shown surviving a direct Metallium Ray from Ultraman Ace. It takes his own weapon being thrown against him to put him down.
• Names to Run Away from Really Fast: Even his Boss Subtitles is "Tyrant Monster"!
• Pointy Ears: Taken from Alien Icarus, and like Icarus, they can fire a hailstorm of energy needles.
• Poisonous Person: Sprays toxic gas from its Bemstar gorge.
• Spikes of Doom: Borrowed from Hanzagrian.
• Super-Strength: As expected from a kaiju whose composition includes Red King with five other formidable kaiju and one alien, Tyrant's physical strength is immense.
• Tail Slap: Borrowed from King Crab.
• The Worf Effect: Defeats Zoffy, Ultraman, Ultraseven, Jack, and Ace with complete ease, and yet is defeated by Taro just as quickly, though by throwing Tyrant's own weapon against him.

Gongoros

First Appearance: Mother's Wish - A Mid-Winter Cherry Blossom Blizzard

An extraterrestrial entity made of pure energy that originates from the Triones M81 Galaxy. It inhabited a graffiti drawing of a saurian monster painted on the wall of a snooty rich lady's house by a mischievous but artistic boy named Masahiro, bringing the drawing to super-sized life.

---

• Art Initiates Life: Gongoros is a mural painting of a kaiju brought to life by an extraterrestrial energy being. Ultraman Taro even defeats the monster by literally erasing it!
• Breath Weapon: Breathes fire.
• Corrupted Character Copy: Gongoros shares several elements with Gavadon from Ultraman, being a child's artwork brought to life by cosmic rays. But unlike Gavadon who's a neutral monster, Gongoros is hostile and sets out to destroy the city.
• Energy Being: Gongoros' true form is an entity of dark energy that is able to inhabit two-dimensional spaces and make them three-dimensional.
• Gasshole: Gongoros farts in Taro's face and at ZAT's planes during its rampage!
• Living Drawing: In its painting form, Gongoros visibly blinks after a lady tries erasing it, giving her a shock.

Elegia

First Appearance: The Phantom Mother is a Monster User!

Originally the deceased pet parrot of a woman killed in a vehicle accident named Seiko Shimada, Elegia was resurrected as a kaiju when an android replica of Seiko (complete with her memories) built by her inventor widower Shingo sought vengeance against motorists for the original Seiko's death.

---

• Breath Weapon: Breathes fire.
• Expy: Elegia is pretty much Hydra from the original Ultraman as a parrot. Right down to hatred of motorists and the ability to breathe fire.
• Giant Flyer: A parrot kaiju.
• Our Ghosts Are Different: Specifically, a lady's dead parrot resurrected by her android replacement as a kaiju to avenge her death.
• Roaring Rampage of Revenge: Sought to kill all drivers in Japan as retribution for Seiko's death under the command of the lady's robot double. Even in a show full of bizarre storylines, Elegia's was definitely one of the weirder ones.

Mottokureron

First Appearance: Pickle the Monster with Salt

A small but gluttonous monster from outer space that came to Earth in search of food. It was raised in secret as a pet by the vegetable-abhorring son of a grocer (who chose to feed the monster his vegetables instead of eating them himself), but soon grew too big to be taken care of properly.

---

• Big Eater: Mottokureron loves to eat. Its Boss Subtitles is even "Gluttonous Monster".
• Breath Weapon: Breathes a green slime that is less dangerous, more disgusting.
• Gasshole: Like Gongoros and Kemujira, Mottokureron farts in Ultraman Taro's face during the fight!
• Make My Monster Grow: Grows from the size of a cat to the size of a kaiju in a matter of days due to being constantly fed thrown-away vegetables. Fortunately, Ultraman Taro is able to reduce the monster to the size of a human by squeezing all of the monster's green slime out of it.
• Meaningful Name: From "motto kurero", meaning "give me more", befitting its gluttonous nature.
• Non-Malicious Monster: If anything, Mottokureron is just hungry. It has no motives beyond finding food to eat, but when it gets too big to be sensibly sustained, it starts causing trouble.
• Spell My Name With An S: Mottokureron or Motokureron?
• Verbal Tic Name: Takeshi, the boy who raised Mottokureron, gave it the name because its cry while it was being fed sounded like it was saying "motto, motto", or "more, more".

Alien Kisaragi Onibanba

First Appearance: Oh, Taro is Being Eaten!

Voiced by: Hiro Kasai (also human form actor)

• Villain: Exit, Stage Left: After Taro simply tosses some Setsubun beans around Tokyo during their battle, Onibanba is forced to flee. Taro does get to clobber her with her kanabou as she leaves though.
• Weaksauce Weakness: Setsubun beans having the same repulsing effect on her as they supposedly do on actual evil spirits.

Memole

First Appearance: She was Wearing Red Shoes...

Played by: Kei Natsukawa

A monster that was originally a childhood friend of Kitajima named Mari. Many years ago, Mari was abducted by Alien Dorzu and given a serum that would transform into a kaiju when she returned to Earth as an adult to visit Kitakjima at ZAT's base and subsequently try to destroy it.

---

• Breath Weapon: Breathes fire.
• Prehensile Tail: Memole uses her tail to good effect against Ultraman Taro, including strangling him with it.
• Smoke Out: Able to fire a toxic red smokescreen from her right hand that allows her to teleport.
• Tragic Monster: Kitajima begs Ultraman Taro not to kill Memole due to how much Mari means to him. Ultraman Taro complies and takes her somewhere into space to live the rest of her life in peace.
• Was Once a Man: Specifically a young girl who was abducted by aliens and experimented on so that she would transform into a kaiju as an adult. The red shoes are all that remain of her.

Alien Dorzu

First Appearance: She was Wearing Red Shoes...

The evil alien who had kidnapped Mari long ago when she and Kitajima were playing as children. His sinister scheme was to transform the girl into the kaiju Memole when she became an adult and then command the creature to destroy ZAT for an easy conquest of Earth.

---

• Invasion of the Baby Snatchers: He kidnaps children while they're out alone and then subjects them to horrible experiments and transformative substances to turn them into giant monsters.
• Manipulative Bastard: Intended to use Kitajima's feelings for Mari to make ZAT reluctant to attack Memole, leaving them completely hopeless against the woman-turned-kaiju.
• My Brain Is Big: Look at his cranium in the picture above.
• Villain: Exit, Stage Left: Dorzu sorta vanishes after Taro defeats Memole, and is last seen leaving Earth after the plan is foiled.

Piccolo

First Appearance: The White Rabbit is a Bad Guy!

Voiced by: Naoko Kyoda

A playful Pinocchio-like alien prince from the the Piccola Nebula who came to Earth for some lighthearted mischief (namely messing around with a boy's pet rabbit). However, he decides to destroy humanity out of disgust after seeing the boy's cruel landlord poison said rabbit for breaking his "no pets" rule.

---

• Beware the Silly Ones: He acts pretty silly and goofy when we first meet him and the worst he does is simply frustrate some people from afar by teleporting a pet rabbit. However, he goes berserk when he sees said rabbit poisoned by the owner's landlord and decides to kill all the entire human race for it. He also gives Ultraman Taro a fair amount of challenge in the battle.
• Know When to Fold 'Em: He eventually realises that fighting Taro will get him nowhere, and ends up requesting the Ultra's help in returning to his home.
• Nasal Weapon: His Pinocchio-like nose can act as a cannon.

Gorgosaurus

First Appearance: The Monster Master

A monster from the 1971 Tsuburaya Productions superhero series Mirrorman who appears very briefly to battle Ultraman Taro while he is out on a trip through space. He successfully injures the hero, incapacitating him for the remainder of the episode.

---

• Canon Immigrant: Gorgosaurus is not the only monster from Mirrorman to appear in the Ultra Series (the other being Dustpan in the notorious Thai co-production Hanuman vs. 7 Ultraman). The creature is actually described in the show as hailing from another universe!
• Half the Man He Used to Be: Gorgosaurus tries to escape after the battle goes south by teleporting away, but Taro blows up his upper body mid-teleportation, leaving his lower half lifelessly falling down.
• Invisibility: The only ability shown by Gorgosaurus in this appearance, which is weird because the Mirrorman version never had that power, only a fiery Breath Weapon.
• We Hardly Knew Ye: The creature solely appears to injure Kotaro for the episode, and is dispatched quite quickly once that bit is dealt with. If anything, the monster was pretty much picked to appear solely because the suit was conveniently available.

Gelan

First Appearance: The Monster Master

A monster that suddenly appeared from underneath Kenichi's school to make a nest for its eggs and hatchlings. However, for much of the episode, Gelan's body is trapped directly under the school, so only its head and tail are exposed, but that doesn't make the creature any less ferocious in defense of its young.

---

• Agony of the Feet: While on a mindless rampage, Gelan is unfortunate enough to step on a katana left behind by the kendo club, whose pointy side is facing upwards. It notably shrieks in pain after that.
• Backpack Cannon: Able to shoot a steady stream of energy blasts from its back.
• Breath Weapon: Breathes fire.
• Cyclops: Has a only single red eye.
• Monster Is a Mommy: Gelan's rampaging is mainly due to the fact that it believes the schoolchildren are endangering its children.
• Non-Malicious Monster: Gelan has no destructive intentions towards the school as it simply wanted to protect its young. For this reason, rather than killing it, Ultraman Taro takes the monster and its babies someplace new to live.
• Tunnel King: Gelan had been hiding underneath Kenichi's school for years, suddenly tunneling to the surface for some reason, although with the mother's case, only its head, neck, and tail could be exposed out of the ground at first.

Veron

First Appearance: Monster Girl's Festival

Voiced by: Takeshi Watabe

A carefree and goofy-natured monster that showed up on Hinamatsuri (aka Doll Festival or Girl's Day). Veron is an alcoholic kaiju who loves to get drunk on sake and boogie to the pop music of the Space Boys.

---

• The Alcoholic: Loves sake and is constantly in a drunken state. Only in Ultraman Taro do you get an alcoholic kaiju!
• Breath Weapon: Breathes fire.
• Fighting Clown: A fight between Ultraman Taro and a drunken kaiju goes about as seriously as one would expect from this show.
• Non-Malicious Monster: Really, the only danger he poses is his drunkenness, and is otherwise totally harmless.
• Water Wake-up: Taro defeats him by waking him up from his drunken rampage, by summoning an Ultra-sized bucket of water from the King Bracelet and splashing its contents on Veron.

Alien File Space Boys

First Appearance: Monster Girl's Festival

An extraterrestrial boy band of pop musicians who come to Earth in search of Veron, who happens to be their band's mascot. During their search for the drunken kaiju, they befriend a feminine boy named Taro (no connection to the hero) and assist ZAT in subduing the sake-loving monster.

---

• Boy Band: An extraterrestrial boy band whose music is the one of the few things that can keep Veron under control. It was the 70s after all.

Orphy

First Appearance: Sing! Big Monster Match!

Voiced by: Eiji Maruyama

A peaceful monster that dwells in Yaijin Valley and wakes up once a year to sing opera music for the nearby villages, supposedly bringing good fortune to those who hear it. ZAT sought to protect the benevolent creature from a gang of human poachers led by the disguised Alien Kaan.

---

• Brainwashed and Crazy: Alien Kaan takes over Orphy's body to drive the monster on a rampage, so Ultraman Taro has to subdue the creature to fish Kaan out and kill him.
• Exposed Animal Bellybutton: Orphy has an exaggerated navel that sticks out quite prominently. It stores a music sheet that the monster uses for singing while Kaan hides in it to take control of the monster.
• Gentle Giant: A completely peaceful kaiju that only seeks to treat people to its lovely and baritone singing voice.

Alien Kaan

First Appearance: Sing! Big Monster Match!

Voiced by: Daisuke Kusano (also human form actor)

A parasite-like alien hunter who comes to Earth in disguise and organizes a gang of human poachers to kill Orphy. However, this was in fact part of a greater scheme by him to parasitize Orphy and mind control the gentle creature into going on a berserk rampage.

---

• Breath Weapon: Breathes fire.
• Karma Houdini: Even though Garaking destroys an airport, blows up several planes, and smashes numerous buildings with no discernible motive, Ultraman Taro doesn't give it a well-deserved Storium Ray because Yuki (who played a volleyball match with the monster) begged Taro not to kill it!
• Rolling Attack: Garaking can curl itself up into a ball to destroy its surroundings by simply crashing into them.

Rindon

First Appearance: The Ultra Father and the Bride have Arrived

A monster that suddenly attacked Tokyo while Nanbara's fiance and mother are visiting from Kyushu. Unfortunately for Nanbara, who is planning to get engaged, Rindon puts his fiance in grave danger and throws a serious wrench into his wedding plans.

---

• Breath Weapon: Breathes fire.
• Losing Your Head: Rindon's defining feature is that its head has a life of its own and will simply reattach itself to its neck if decapitated. In fact, this ability is so great that the creature's Boss Subtitles is "Invulnerable Monster", and the Father of Ultra had to step in to help Taro kill it permanently.
• Off with His Head!: Ultraman Taro does this to him, but quickly finds out that it's not enough.
• Tunnel King: Appears in Tokyo by bursting out of the ground in the middle of the city.

Dorobon

First Appearance: Steal the Ultra Life

Voiced by: Takeshi Watabe

---

• Breath Weapon: Breathes fire.
• Carry a Big Stick: His weapon of choice is an iron club covered in spikes.

• Meaningful Name: From "dorobou", meaning "thief".
• Oni: Based on them. He even wields a kanabo!
• Super-Strength: Dorobon was able to rip off Jack's Colour Timer with his bare hands. And keep in mind that Colour Timers are surgically grafted onto an Ultra's body! Yeah that's some real strength there.

Samekujira

First Appearance: Farewell Taro! The Ultra Mother

A shark-whale monster awoken by Alien Valky who intended to capture it to achieve glory. Samekujira destroyed many ships (including the one sailed by Kenichi and Saori's father) in its rampage, only to be quickly destroyed by Ultraman Taro, much to Valky's displeasure.

---

• Engineered Heroics: Alien Valky had released Samekujira to attack ships around the coats of Japan, with the intention of stepping in and "capturing" the monster in order to achieve glory. However, Taro killing Samekujira was not part of the plan.
• In a Single Bound: Thanks to the wing-like fins on its sides, Samekujira is capable of leaping great distances.
• Meaningful Name: His name means "Shark-Whale" in Japanese.
• Mix-and-Match Critters: As his Meaningful Name suggests.
• Sea Monster: Sorta looks like a giant sawfish, but weirdly it possesses legs.
• Threatening Shark: It's where the "Same-" part of his name comes from, with a sawshark being the specific inspiration.

Alien Valky

First Appearance: Farewell Taro! The Ultra Mother

Voiced by: Shinya Kashima

The greatest fisherman in the universe, Alien Valky came to Earth in search of glory through catching the legendary Samekujira and conquering Earth by defeating Ultraman Taro. However, he was less than happy when Taro killed the monster fish, and so he switched over to trying to kill Kotaro as revenge for the humiliation.

Notable for being the final opponent of Taro's series yet not of Taro himself, Alien Valky has reappeared many more times in the Ultra Series against various other Ultra heroes. Although usually portrayed as a skilled hunter or fighter seeking to make himself famous in the universe, Alien Valky has appeared in other roles too, like as a major antagonist in Ultraman Ginga.

---

• Breakout Villain: Is one of the most iconic opponents of Ultraman Taro, earning him many reappearance since his return in Ultraman Mebius.
• Egomaniac Hunter: His debut in Taro depicts him to be one of these, hunting the space whale kaiju Samekujira.
• Engineered Heroics: He unleashed Samekujira on Japan so that he could defeat it and attain glory.
• Fake Ultimate Mook: Even though Valky was the final enemy of the series, he was killed by humans without any help from Ultraman Taro. This was because Kotaro wanted to make a point to Kenichi that he didn't need the power of Ultraman Taro to defeat enemies.
• Family-Unfriendly Death: His Man on Fire demise is noted to be especially graphic, even for the standards for Ultra Series back in the 70s, let alone a usually Lighter and Softer show like Ultraman Taro.
• Glory Seeker: In almost all his appearances (most prominently his debut), Valky's goal is to achieve fame throughout the universe.
  • Glory Hound: Valky isn't above destroying a few cities or having to kill a few Ultra heroes if it's gonna earn him a reputation in the universe. And he's pissed when Taro kills Samekujira, so he tries to kill Kotaro in retribution.
• Kill It with Fire: Kotaro manages to defeat Valky without turning into Ultraman Taro by tricking him into destroying oil rigs that end up setting the alien on fire and burning him to death.
• Meaningful Name: Valky's name is derived from the Japanese pronunciation of "Valkyrie", as the Valkyries of Norse myth took warriors who died in battle to Valhalla and Alien Valky was the final enemy that Ultraman Taro faced before Kotaro gave up his Ultra Badge to live the rest of his life as a normal person.
• Power Crystal: Has a small red crystal on his head that fires energy bolts.
• Spell My Name With An S: Also called Valkie.

Introduced in Ultraman Story

Although Ultraman Story debuted some ten years after Ultraman Taro ended, Taro remains the focus of the film and several of its new characters go on to appear in subsequent series. Thus they have been placed here for convenience.

Juda

The film's Big Bad. Juda is a malevolent devil-like being originally defeated fifty thousand years ago by the Father of Ultra. He seeks to destroy the Ultras and M78 so that he can then destroy the universe without opposition, To this end, he sends out many old foes of the Ultra Brothers, notably Alien Hipporito and Enmargo, to destroy them and also unleashes the mighty Grand King to assault Land of Light.

Juda also reappeared in the 1983 spin-off miniseries Andro Melos as its Big Bad once again, this time accompanied by his newly-introduced siblings Mold and Gina. The three have since returned in other Ultraman shows like Ultra Fight Victory and Ultraman X as recurring secondary villains for the Ultra heroes to face.

---

For tropes pertaining to Juda as a whole, see here.

• Big Bad: Of Ultraman Story and later on Andro Melos.
• Bilingual Bonus: Has the kanji for "King" on his forehead.
• Energy Being: In Ultraman Story only. This is completely ignored in later appearances.
• Evil Laugh: Has a pretty good one, like any self-respecting villain.
• Galactic Conqueror: His current characterization; he seeks to take over the entire universe alongside his siblings Gina and Mold.
• Humanoid Abomination: The Father of Ultra describes him as such, saying that he was born from a distortion in the universe and referring to him as the spawn of the Devil.
• Names to Run Away from Really Fast: Named after Judas, the apostle who infamously betrayed Christ.
• Non-Action Big Bad: Due to being an Energy Being, he really can't fight the Ultras face-to-face. However, this is dropped in later appearances, where as a physical entity, he is now capable of fighting the Ultras and regularly does so.
• Omnicidal Maniac: Presented as such in Ultraman Story. He seeks to spread the power of the space distortion he was born from, which would destroy the entire universe in the process. After his siblings were introduced though, he became more of a Galactic Conqueror.
• Sealed Evil in a Can: The Father of Ultra originally imprisoned him by ending the own spatial distortion he came from, but after 50 000 years, the distortion and Juda have returned.
• Villain: Exit, Stage Left: Flees after Grand King is defeated and is never seen again by the Ultra Brothers. He does finally die in Andro Melos though.

Grand King

The ultimate weapon of Juda, Grand King is a monstrous dinosaur-like robot empowered with the spirits of several monsters defeated by the Ultra Brothers, making it among the most powerful foes of the heroes have faced so far. Juda sends it out to attack the Land of Light after Alien Hipporito succeeds in incapacitating the Father of Ultra and while Taro is distracted with battling Enmargo.

Despite its debut film being one of the lesser-known entries of the franchise, Grand King's impressive appearance and formidable power has made it a fairly popular monster. It has since gone on to appear in a number of later Ultra Series as a very powerful enemy of the Ultras. In all of these appearances, it is given an updated form, such as Super Grand King, Maga-Grand King, or Grand King Megalos.

---

• Barrier Warrior: Able to form an energy shield around its body that prevents the Ultra Brothers from making close contact with it.
• Breakout Villain: For a monster whose only appearance prior to 2013 was a fairly obscure compilation movie, Grand King has proven popular enough to become one of the most powerful recurring foes of the Ultramen.
• Breath Weapon: Its immensely powerful signature ability, the Gran Laser. However, Grand King can also fire the same beam from its forehead and tail.
• The Dragon: To Juda, acting as his greatest tool of destruction.
• Humongous Mecha: Grand King is a gargantuan dinosaur-like robot powered by the vengeful spirits of Alien Baltan, Red King, Gomora, Alien Mefilas, Eleking, and Alien Hipporito.
• Hybrid Monster: Grand King is powered by the vengeful spirits of six foes from past series. Its appearance also takes cues from other monsters, such as its horns evoking Gomora's head crests and the claw on its right hand resembling Alien Baltan's pincers.
• The Juggernaut: Always. In its debut, it survived being hit by multiple Finishing Moves at once, and then completely overpowered Ultraman, Zoffy, Ultraseven, Ultraman Jack, Ultraman Ace, and Ultraman Taro, forcing the Ultra Brothers had to merge their powers with Taro to even stand a chance.
• The Power of Hate: Part of the reason why Grand King is so strong is that the monster souls that power its body hate the Ultramen that much for defeating them.
• Right Hand of Doom: Its right hand is a powerful drill, while its left hands is an enormous claw capable of grabbing the Eye Slugger without being harmed.
• This Is a Drill: Equipped with one as its Right Hand of Doom.

Dokkun

A child monster encountered by a young Ultraman Taro at the beginning of the film when he is training to become a great warrior out in a canyon somewhere in M78. Taro tries to start a fight with the creature until the Mother of Ultra intervenes to scold him for his mischief.

---

• Benevolent Monsters: The Mother of Ultra describes Dokkun's species as an entirely peaceful race. However, that doesn't stop the young Taro from picking a fight with him.
