While Zordon continues trying to understand the mysteries of the coins, Rita launches her first attack, stealing the Dragon Power Coin and sending down hordes of Putty Patrollers to menace the human civilisation. During the assault, Zordon is cornered and then saved by five residents of the village - Geki, the younger brother of the village's elected leader Burai; Goushi, a scholar and astronemer; Dan, a knight and delivery boy; Boi, a farmer and explorer; and Mei, an artist and Boi's gleeful companion. Badly beaten and outnumbered but refusing to give up, the five humans continue to fight until they're completely surrounded ... whereupon the Power Coins come to them in a cloud of light and grant them their power, making them into a new team of Power Rangers known as the Mighty Morphin' Rangers. Upon seeing her forces be defeated by a gang of the humans she despises, Rita becomes even more determined to conquer Earth, with the newly-formed Rangers continuing to fight her forces with the assistance of the veteran Zordon and the rest of their village.
While the Rangers continue to develop their skills and bonds with one another, Rita exploits her stolen Dragon Power Coin, kidnapping Burai and brainwashing him into becoming her evil Green Ranger, equipped with an ancient treasure known as the Dragon Armour. After coming dangerously close to killing the Rangers, the Rangers are able to break the spell and bring Burai over to their side, allowing them to reach six members and also gain new options for combat with his Dragonzord and later the autonomous Brachiosaurus Zord known as Titanus. As Rita's forces grow in number and power, the Rangers, backed by their allies, fight to protect the ancient Earth from the forces of evil.
The Mighty Morphin' Rangers:
- Geki/Mighty Morphin' Red Ranger: The Leader,
- Goushi/Mighty Morphin' Black Ranger: The Smart Guy,
- Dan/Mighty Morphin' Blue Ranger: The Big Guy,
- Boi/Mighty Morphin' Yellow Ranger: The Lancer,
- Mei/Mighty Morphin' Pink Ranger: The Heart
- Burai/Mighty Morphin' Green Ranger: The Sixth Ranger,
Their Allies are:
- Zordon: The Big Good, an individual who has some experience when it comes to Power Rangers fighting the forces of evil.
- Alpha 5: Zordon's robotic assistant and the maintenance operator for the Command Centre and the Dinozords.
- Otome: Goushi's older sister and the Rangers' Honorary True Companion.
And they're up against:
- Rita Repulsa: The Big Bad, the daughter of Vahill and the wife of Lord Zedd. The leader of a small splinter group from the now destroyed United Alliance of Evil, she's intent on conquering Earth to spite the Eltar Rangers and to allow her a base of operations that's out of the way.
- Goldar: The Dragon, a manticore-like Titanian Warrior clad in golden armour who serves as her main enforcer and Geki's Arch-Enemy.
- Finster: The Evil Genius, a Claydoionian scientist and scientist who creates monsters for her with his skills and Monster-Matic machine.
- King Sphinx: The Brute and Goldar's own Dragon, an Egyptian sphinx-like humanoid who assists Goldar in fights and off-duty serves as his Professional Butt-Kisser.
- Baboo and Squatt: The resident Bumbling Henchmen Duo, a pair of rejected United Alliance of Evil soldiers who were picked up by Rita along the way and serve as her spies, saboteurs and scapegoats. With Baboo being an Pougite alchemist and Squatt being a Mygorian recorder, they tend to be sidelined in most capacities, although they do make their own efforts to fight the Rangers.
- Scorpina: The evil Sixth Ranger, the wife of Goldar and "daughter" of Count Ethegon who arrives on Earth to provide assistance to the villains.
Recurring Power Rangers Redverse Tropes:
- Brats with Slingshots: The Thunder Slingers, which are basically slingshots that fire energy bolts.

- Cool Bike: The Battle Bikes, three bikes for the Red, Black and Blue Rangers which have sidecars for the Green, Yellow and Pink Rangers respectively.
- Cool Sword: Geki's Tyranno Sword, which can transform into the Tyranno Battlizer Morpher.
- Custom Uniform: The Green Ranger outfit stands out from the rest of the team due to its golden Dragon Armor vest and armlets which Geki briefly uses after Burai's temporary depowering. The outfit also has golden trims on its boots and gloves, and a red stone fitted into the helmet that is said to be made by the same material as the Power Crystals.
- Double Weapon: Dan's Triceratops Lance, which can transform into the Mighty Maces.
- Five-Man Band: The Mighty Morphin' Rangers.
- Home Base: The Command Centre, which is also Zordon and Alpha 5's residence. The Rangers themselves have their own homes in the Home Village, but do tend to meet up at the Command Centre.
- Humongous Mecha:
- Animal Mecha: All of the Dinozords, which are all based on different varieties of prehistoric animal (and a dragon).
- Combining Mecha:
- Tyrannosaurus Dinozord + Mastodon Dinozord + Triceratops Dinozord + Sabre-Tooth Tiger Dinozord + Pterodactyl Dinozord = Dino Megazord, which has Carrier Mode and Warrior Mode.
- Dragonzord + Mastodon Dinozord + Triceratops Dinozord + Sabre-Tooth Tiger Dinozord = Dragonzord Battle Mode
- Dragonzord Battle Mode + Tyrannosaurus Dinozord + Pterodactyl Dinozord = Mega Dragonzord
- Mega Dragonzord + Titanus = Dino Ultrazord

- Make My Monster Grow: Rita Repulsa, being the Trope Namer and all.Rita: Magic wand, MAKE MY MONSTER GROW!
- Maker of Monsters: Finster, who sculpts the monsters from magical clay and then puts the figurine in his Monster-Matic machine to "bake" them into a full-sized monster.
- Mix-and-Match Weapon: Burai's Dragon Dagger, which is both a dagger and a flute that can be played to create different spells.
- Mooks: The Putty Patrollers and their Putty Captains.
- Powered Armour: Burai's Dragon Armour, the only recurring piece of the Rangers' arsenal that's man-made, even though the metal that forms it was mined from a meteorite.
- The Straight and Arrow Path: Mei's Pterodactyl Bow, which can transform into the Morphin' Mesmeriser.
- Supervillain Lair: The Moon Palace.
- Swiss-Army Weapon: In addition to the Blade Blasters, all of the main five's Power Weapons can transform into different forms, with the Red Ranger's weapon being able to become a Battlizer Morpher and the other four Rangers' being able to become different weapons.
- Transformation Trinket: The Dino Buckle Morphers, which are belt buckles that hold the Power Coins. Burai's Morpher is a gold-plated version known as the Dragon Buckle Morpher.
Tropes specific to Mighty Morphin':
- Adaptation Expansion:
- All of the Zyu2 monsters (save for Pirantis Head, who becomes a Ascended Extra in the sequel, and Rhinblaster due to not fitting in the ancient history setting), the Rat Monsters and Turkey Jerk from MMPR Season 2, and Repellator and Incisorator from MMPR Season 3 are included.
- Lokar gets given a proper origin and explanation - he's one of the twelve pieces of Lord Omnicron that was scattered across the twelve timelines after his death and then transformed into a whole new entity of evil, similar to the Inquisitor.
- Adaptational Explanation: The Deus ex Machina related to the Legendary Weapons from Zyuranger is given its own, more acceptable explanation - the Rangers' quest isn't on a time limit, and rather than simply leaping into the Rangers' hands, they find that the weapons appear broken, worn-down and unusable. As the other Rangers are about to leave in despair, Geki takes the weapons from the stone they were imbedded in and says that the weapon is only the focus and the power to fight Rita is within them. When the Rangers then touch the junk weapons with renewed courage, the Power Weapons then transform into their true forms.
- Adaptational Heroism: Compared to his Zyuranger counterpart, Burai was always a good person who was Brainwashed and Crazy rather than acting on his own violation out of jealously, and after the spell is broken immediately joins the Rangers as a full-fledged hero.
- Adaptational Jerkass: Finster acts more like a downplayed version of his Zyuranger counterpart Pleprechaun, although he's still always polite to Rita.Finster: You can't rush art!
- Adaptation Personality Change: Well, in this case, Adaptation PERSONALITY, considering how utterly flat and side-lined compared to the random children the Zyurangers were.
- Geki is a loyal Nice Guy much like his Zyuranger counterpart, but here he has his fair share of flaws and insecurities, most notably his recklessness and inability to detect scenarios where he can't win, as well as his fears of being a bad leader.
- Goushi is The Stoic with some Insufferable Genius tendencies, well aware of his intelligence and tending to get frustrated when others don't display the same interests as him, but unafraid to admit when he's wrong and still being friends with his teammates.
- Dan is The Prankster and The Slacker, immature and with a tendency to be distracted by whatever piques his interest at that moment whie also becoming a lot more Hot-Blooded in battle, but also with never a mean word to say about anyone and always pursuing noble goals.
- Boi is a frustrated but caring individual with a Inferiority Superiority Complex and a tendency to make rightly-aimed criticisms and ask questions that she feels are important and have not yet been answered by Geki or Zordon.
- Mei is a Classical Anti-Hero, a wide-eyed but inexperienced teenager whose idealism leaves her emotionally fragile and whose gullibility often leads to her being tricked, but still maintaining a sweet nature and surprising moments of cunning.
- Adapted Out: Some of the monsters, such as Babe Ruthless and Samurai Fan Man, are not included due to not fitting the setting of the 8th century BC, instead being reserved for the sequel.
- Advanced Ancient Humans: While nowhere near as advanced as modern humans, the tribe of humans who live around the Command Centre in the 8th century BC are far more advanced than any other human civilisation from the time, with a primitive democratic system, a basic writing system, woodcutting, wagons with wheels, weaving, bow and arrows, and slingshots using stones. Zordon even comments that the humans developed these basic technologies faster than the ancient Eltarians did.
- A God I Am Not: Zordon and Alpha 5 are viewed as gods or at least messengers of them by the ancient humans, despite them frequently informing them that they're just Sufficiently Advanced Aliens.
- Amphibian at Large: An early monster Rita sends after the Rangers is the Terror Toad, a bloated man-sized toad monster whose primary method of attack is to swallow the Rangers whole. The creature is so powerful that Zordon has to step in with his own Ranger powers since the inexperienced Rangers are unable to do any damage to it with their human-built weapons.
- Animal-Themed Superbeing: The Rangers are based on dinosaurs, save for the Green Ranger, who has a dragon motif.
- The Artifact: Daizyuzin, the name of the Dino Megazord's counterpart in Zyuranger, is used as the name for the sentient AI system that the Dinozords share. The Dragonzord and Titanus have their own AI system known as Gouryuzin (the Zyuranger counterpart of Dragonzord Battle Mode).
- Ascended Extra: After being a Advertised Extra throughout MMPR's merchandise, King Sphinx is promoted to the main villain group as Goldar's personal Dragon.
- Beware My Stinger Tail: Scorpina's deadliest technique is her giant form's electrocuting tail sting.
- Big Creepy-Crawlies:
- Fighting Flea, a gigantic flea that can spread microscopic organisms that constantly project quiet sounds into a human's brain, driving them mad.
- The Slaying Mantis, a human-sized anthropomorphic praying mantis with martial arts skills ... and a sense of honour and pride.
- Spiderarmic, an anthropomorphic spider with multiple limbs and the ability to spread a virus that knocks people out cold for hours at a time.
- The Weaveworm, a hulking semi-anthropomorphic yellow caterpillar with empty black eye sockets, capable of mind controlling humans via its poison.
- Stab Beetle, a naturally giant stag beetle who refers to the Giant Super Putties as "clay comrades" and has pincers capable of forcibly breaking apart the Dino Megazord.
- Bling of War: The Dragon Shield worn by Burai and temporarily Geki. Goldar also wears golden armour, as his name suggests.
- Body Horror:
- The battle against the Terror Toad plays up the Swallowed Whole motif for horror, with the toad himself bloating up the more people he consumes, and when Mei is the only Ranger left we get a close-up shot of the people trapped inside struggling to escape, with the silhouettes of the other four Rangers and several screaming people becoming visible from within for brief moments, all the while Terror Toad describes to the terrified Mei how there is no escape and how he's going to subject her to the same fate.
- Bullying a Dragon: In a moment of true stupidity, a normal-sized Goldar tries to attack the Dino Megazord, which promptly punches him into a cliffside.
- Bumbling Henchmen Duo: Baboo and Squatt. Goldar and King Sphinx are also this at their most comedic.
- Canon Foreigner: Bubba, the Creepy Child nephew of Rita and the counterpart to Kai.
- Dark Action Girl: Scorpina.
- Dope Slap: Rita tends to whack her henchmen on the head with her wand whenever they fail or do something stupid.
- Everyone's Baby Sister: Inverted with Burai, who can be described as a Cool Big Bro for the entire team.
- Full-Potential Upgrade: Mid-way through the first season, after they realise that their Blade Blasters and human-built weapons won't be enough to fight against Rita's full forces, the Rangers go on a quest to find the Power Weapons, legendary weapons that were said to have emerged from the slain body of a five headed dragon.
- Gender Flip: Boi, to ensure Two Girls to a Team. It's pretty ironic.
- Gentleman and a Scholar: Zordon, as usual. Finster is also this, being a Affably Evil individual as well as a skilled blacksmith, scholar, medic, and technician.
- Golem: The Putty Patrollers. Technically, the majority of the monsters are these, as they're clay sculptures brought to life. On occasion, when a monster is destroyed, we're shown a pile of rocks falling to the ground.
- Hypocritical Humor: Rita despises humans, viewing them as ugly and weak. She also happens to be a Human Alien.
- Kamehame Hadoken: Burai tends to channel his lightning attacks into energy projectiles.
- Law of Chromatic Superiority: In addition to getting the series-standard Battlizer, Geki's Zord, the Tyrannosaurus Dinozord, is the only Zord that can perform finishing moves on giant-sized monsters by itself, since it's the only bipedal type out of the main five.
- Magic Potion: Baboo's main expertise.
- Mammoths Mean Ice Age: Averted. Woolly mammoths still exist in the 8th century BC (they were still around until around 500 years after the Great Pyramid of Giza was constructed, just in case you need more proof of how ancient that structure is), but dwell in a relatively multi-biome environment.
- Mid-Season Upgrade: After Burai loses his powers, Geki is transferred the Dragon Shield and the Dragon Dagger. He didn't use them very often, however, most likely due to them reminding him of his failure to save Burai's powers. It only sticks around for a season, though, since Burai later gets his powers back and is given the shield and dagger back by Geki.
- Motor Mouth: Boi whenever she's nervous.
- Ms. Fanservice: Scorpina. At least when she isn't using her ultimate power.
- Our Genies Are Different: The Jackal Genie, in contrast to the one-note monster from Mighty Morphin'. He is a neutral individual who grants the wishes of those who possess his lamp, so long as they can be accomplished by his power (explaining why Rita couldn't ask him to release Lord Zedd).
- Readings Are Off the Scale: Cyclopsis's CPU needs to adjust to each form the Rangers' Zords take when engaged in combat with them. Once the Rangers discover this, they begin rapidly switching between Zord modes and combinations, which overwhelms the Warzord's computer and causes it to lock up.
- Shotguns Are Just Better: Squatt's blunderbuss, something he didn't get to use in the original Mighty Morphin'.
- Tome of Eldritch Lore: Subverted with the Sky Book, which is hidden in the Home Village's temple and was found alongside the meteor that was forged into the Dragon Shield. The founders of the village hid it as they feared that it contained eldritch and demonic power and spells... only for Zordon to be shown it and identify it as a book Zedd borrowed during the events of Ancient Guardians and never returned.
- Winged Humanoid: Goldar, fitting with the manticore motif, and King Sphinx.
