As the show spans 10+ seasons and two movies, it is not surprising that Happy Heroes has a lot of characters.

Heroes and Allies
The Five Superheroes
As a Whole
The Supermen as they appear from Season 10 onwards. From left to right and top to bottom: Sweet S., Careless S., Happy S., Careful S., and Smart S.
The five main heroes.- Badass Adorable: All five of them are absolutely adorable little robot kids... who can and will beat up Big M.'s monsters like nobody's business.
- Cute Machines: All five of them are absolutely adorable-looking, chibiesque robots.
- Demoted to Extra: In Happy Heroes and the City of Mystery, all the Supermen except for Careful S. are reduced to making brief appearances when they are summoned by the Skill Balls, inventions that Doctor H. created to help Careful S. out during his journey on Planet Earth.
- Kid Hero: One episode reveals them to be in 3rd grade, making them around eight years old, at least mentally.
- Letter Motif: Their Chinese names all follow the theme of "__心超人" ("__xin chaoren"), with the blank representing a different Chinese character that forms with "xin" to make a word describing that particular Superman - Kaixin Chaoren (Happy S.), Tianxin Chaoren (Sweet S.), Huaxin Chaoren (Smart S., Chinese name Flowering Heart Superman), Chuxin Chaoren (Careless S.), and Xiaoxin Chaoren (Careful S.). This name scheme is applied to the Supermen besides the ones that form the main team as well.
- Mental Picture Projector: All five of them have memory projectors built into them, allowing them to show their memories to others.
- Ridiculously Human Robot: They eat human food, they are seen crying (and emoting in general), and they actually look like humans in contrast to the other robots on Planet Xing.
- Robot Kid: All five of them are clearly meant to be kids, what with the fact that they mostly have higher-pitched, childlike voices and are shown to be in 3rd grade in one episode.
- Robot Superhero: They are all human-like robots who defend Planet Xing from Big M. and his monsters.
- Sibling Team: By technicality, they're all siblings since they were all formed from Jixie Stones at the same time (with the exception of Careful S., who comes later). They work together to fight monsters.
- Something Person: The group is often referred to as the Supermen.
- Sudden Eye Color: In the pre-art shift seasons, all the Supermen except Careful S. have plain black eyes with highlights inside. In Season 10, the black parts are given a more noticeable brown hue.
- Superheroes in Space: By their very nature as having been born on Planet Xing. They've taken their adventures to other planets too, such as Planet Guling.
Happy Superhero (Happy S./Hero Kai)
The frontman of the group. Happy S. is brave and impulsive, often being the first to act when there are monsters. Has the superpowers of flying as well as super-strength, and therefore the ability to perform the Happy Knight Punch and similar moves. His choice of weapon is a boomerang that's equipped to his helmet.
- Does Not Know His Own Strength: This is particularly demonstrated in Season 6 episode 22, where he can't hold a dinosaur egg unless he learns how to hold other items - such as tofu and a tiny wooden table - without them crumbling within an instant.
- Battle Boomerang: The little wings on the sides of Happy S.'s helmet can come off and form a boomerang which he sometimes uses when fighting monsters.
- Brought Down to Normal: In one episode he loses his superpowers.
- Brought Down to Badass: He still defeats the villain though.
- Chest Insignia: A yellow heart.
- Flying Brick: Has Super-Strength and the ability to fly.
- Hot-Blooded: Gives a lot of passion to things he does. Once he demolished a skyscraper just to save a kitten.
- Keet: He’s very energetic and sweet.
- Megaton Punch: Due to his super strength, Happy S.'s signature Happy S. Punch often sends his foes flying into the sky, if not higher.
- Mercury's Wings: Happy S. has yellow wings on the sides of his helmet that can come off and combine to become a Battle Boomerang.
- Power Fist: His signature attack is the Happy S. Punch.
- Primary-Color Champion: He has all three of the primary colors in his design - he's mostly red, but also has a yellow heart insignia and wings, and a blue gem on his forehead.
- Red/Green Contrast: Happy S.'s heroic shade of red contrasts with Big M.'s villainous green armor.
- Red Is Heroic: He is the leader of the heroes and is mostly red in color.
- Sweet Tooth: Loves chocolate and other sweet treats.
Sweet Superhero (Sweet S./Hero Tian)
- Action Girl: Downplayed. Sweet S. is nowhere near as strong as the other Supermen, but she's still a hero who can and will help the other Supermen fight evil whenever it's needed.
- Barrier Warrior: She often uses her bubble attack to create a shield and block herself and others from incoming attacks.
- Bubble Gun: Sweet S. has the ability to shoot bubbles out of her hands, which have a bunch of uses from being a barrier to fend off attacks to a being mode of transportation.
- Bubble Shield: She can use her bubbles as barriers to shield the rest of the team from blows.
- Chest Insignia: A pink-red first aid cross, symbolizes her healing abilities and protective personality.
- The Colored Cross: She has a pink cross on her outfit to show she's the nurse of the team. Its pink color is more obvious in the Season 10 Art Shift, which lightened it.
- Girlish Pigtails: Has two small ones poking out the bottom of her helmet.
- Girliness Upgrade: Of a sort. The new art-style changes her suit into a dress.
- The Heart: Sweet S. literally embodies kindness, and serves as the moral conscience and mediator of the team.
- Heart Is an Awesome Power: Her main superpower is to create bubbles... which are surprisingly effective as shields, a mode of transportation, etc.
- Heart Symbol: Several appear on her helmet, fitting for the heart and nurse of the team.
- Lethal Chef: Sweet S. is a notoriously bad cook, so much so that the other Supermen do everything in their power to avoid eating whatever she cooks whenever she's the one making food for them.
- Modesty Shorts: Is shown wearing them under her Art Evolution-gained dress in some shots.
- Pink Is Feminine: She is the only member of the team that wears pink on a regular basis, and as the designated girl on the team makes for a fitting color motif.
- The Smurfette Principle: She's the only female out of the Supermen.
- Team Chef: Sweet S. makes a lot of food for the other Supermen... unfortunately for them, since her food is absolutely awful.
- Weak, but Skilled: Physically speaking, Sweet S. is exhibited to be much weaker than the other superheroes. However, her intelligence and superpower prevails in fighting monsters.
- Women Are Wiser: Parodied. In one episode, she had to prove to Smart S. that females were as smart as males.
Smart Superhero (Smart S./Hero Hua)
- Ambiguously Brown: He's the only hero out of the team with noticeably brown-colored skin.
- Chest Insignia: A bright yellow magnet, fitting with his powers.
- Elemental Hair Colors: Has striking, spiky blonde hair, much like his magnetic powers.
- Iconic Item: Being a narcissist, he's often seen with a handheld mirror that has a similar green, red, and blue color to him.
- The Lancer: To Happy S. The two have a good relationship though.
- Lost in Translation: The name "Smart S.", from the Lookus dub, does not fit the character's Narcissist personality. His original Chinese name seems to be a magnetism/romantic attraction pun more properly corresponding to that trait, which seems to have gotten muddled up during translation. The Miao Mi dub names him "Romeo", which fits the characteristic better due to its romantic connotations (the idea being he's hopelessly in love with himself).
- Jerk with a Heart of Gold: Ego and vainness aside, he is still a hero who helps when he can.
- Narcissist: He tends to refer to himself as stuff like the "main character", and loves to mention how handsome he is.
- Non-Indicative Name: His English name most of the time is "Smart S.", which isn't very descriptive of his actual primary character trait of being narcissistic and vain. The Miao Mi dub rectifies this by renaming him "Flowering Heart Superman" and "Romeo", the former of which is a literal translation of his original Chinese name and the latter of which conveys the idea of a hopeless romantic better.
- Magnetism Manipulation: Smart S.'s primary superpower is to attract objects with his Smart S. Magnet.
- Shock and Awe: Electricity is among his powers.
- Vitriolic Best Buds: A sibling variation, but this is basically his relationship with Careful S. He mostly acts with jealousy and snarky smugness towards him, but he still genuinely cares about him and will protect him if needed.
Careless Superhero (Careless S./Hero Chu)
- Chest Insignia: A yellow circle. The art-style change removes it.
- Crouching Moron, Hidden Badass: He's very forgetful, but he's surprisingly good with weapons for someone with such a trait.
- Dreary Half-Lidded Eyes: His default expression, most likely in reference to his somewhat dim-witted personality.
- Gadgeteer Genius: He sometimes makes inventions, but they often turn out strange, like the rice cooker that looked like a toilet.
- Genius Sweet Tooth: He is usually seen with a lollipop. According to a picture launched by the creators, the lollipops he eats are very strangely flavored.
- Gun Nut: Careless S. has a genuine fascination with guns, enough to where a Season 5 episode has him getting in trouble with the teacher for keeping guns around, and he has a reaction as though he's falling in love with a specific gun in Season 10 when he sees it for the first time.
- Playful Cat Smile: He sometimes makes this face when he’s content.
- Science Hero: He builds weapons to help himself fight alongside the other Supermen, placing him on the technology end of the trope.
- Shorter Means Smarter: He’s commonly shown to be the shortest of all the Heroes, and despite his ditziness, he’s quite smart.
- Simpleton Voice: The Lookus English dub gives Careless S. a much deeper, stupider-sounding voice to accentuate his forgetfulness.
- Superhero Packing Heat: He usually uses guns, missiles, or guns that shoot missiles as his main weapon.
- The Smart Guy: Crosses over with Genius Ditz.
Careful Superhero (Careful S./Hero Xiao)
- Brainwashed and Crazy: In the 1st Movie, by the Shapeshifter. He breaks out of it eventually.
- Chest Insignia: Planet Gray's symbol to represent how he was continuously used by evil from Season 1 to 9. Adopted Kalo's triangle starting from Season 10 likely to reminisce their companionship as 侠义双雄 (the Gallant duo).
- Chronic Hero Syndrome: Pretty much the second-most likely to jump in to help, apart from Happy S.
- Cute Little Fangs: He’s got one, mainly shown whenever he smirks. The fact that he looks like a cat doesn't help at all with his allergy.
- Dark Is Not Evil: Main colour is black (and later purple), Pre-Art Evolution symbol is for the Big Bad’s planet, quite unemotive and quiet… And also genuinely heroic and nice.
- Determinator: Careful S. stands for determination and willpower. This is displayed in all seasons, but especially in Seasons 3, 7, 10, and 11.
- Facial Markings: One of his split-personality duplicates has noticeable red-colored physical traits to indicate his evilness as his main characteristic. One of these traits is that he has two red facial markings, one on each cheek.
- Flash Step: He often gets around by using something like this, where he teleports short distances between given points.
- Genius Bruiser: He is quite intelligent for his age, and deadly with a sword. One of his attacks is also a Roundhouse Kick.
- Heroic Ambidexterity: Usually wields two swords (morphed by Kalo) in combat. Can engage with two or more different targets in battle (with or without duplicates), proving to be a prowess in battle. see Season 11.
- Heterosexual Life-Partners: With Kalo, although there are hints of Ship Tease.
- Iconic Sequel Character: Just barely averted. Careful S. is perhaps even more beloved than Happy S., but he doesn't make his first official appearance in the series until the finale of Season 1, Early Bird Cameos in the Season 1 intro and posters aside.
- Literal Split Personality: An episode of Season 3 has him split into multiple distinct clones of himself, each with their unique personality (all their personalities are apparently part of the main Careful S.'s personality according to Doctor H., though since Careful S. is The Stoic he doesn't display any of these traits). The specific duplicates are named Naive Careful, Ancient Careful, Rebel Careful, and Evil Careful.
- Nerves of Steel: Tends not to show much emotion, even when in danger.
- No Sense of Direction: Downplayed compared to most examples, but he still gets lost easily without visible directions. Doctor H. even mentions this trait as part of a Spot the Imposter situation in the First Movie.
- Non-Standard Character Design: The pupils of his eyes are designed differently from the other Supermen of his team. His look more like real-life eyes, having an iris and a pupil, whereas the other Supermen have just a simple black pupil with a highlight inside.
- Not So Stoic: Despite him being cool-headed mostly, there are quite a lot of times where he’ll show more emotion. The most notable and famous example being his reaction to Kalo’s death.
- Perpetual Frowner: It's not especially often that Careful S. smiles, particularly in the earlier seasons, and when he attempts to smile on command, it looks quite terrifying.
- Plot Allergy: To cats. If he comes into contact with one, he starts sneezing and coughing.
- Purple Is the New Black: Later seasons change the color of his suit from black to purple.
- Rubik's Cube: International Genius Symbol: He is exhibited to be very intelligent, and he is constantly seen with a Rubik's Cube.
- Super-Empowering: At least one episode shows that Careful S. can temporarily give others the ability to duplicate like him simply by touching them.
- The Big Guy: Fills this role for the team in a non-physical sense, being around the same size as the rest of them but still the most skilled at fighting.
- The Quiet One: He doesn't talk as much as the other heroes.
- The Un-Smile: Whenever he tries to smile on command, it looks utterly terrifying
. Downplayed in later seasons. - Vitriolic Best Buds: A sibling variation, but this is basically his relationship with Smart S. He mostly ignores his attempts to get under his skin (although he does have a couple moments of sniping back) but he still genuinely cares about him and will protect him if needed.
Kalo
Kalo
Kalo is the gray-colored one with the blue flames on his head. Next to him is Careful S.
Formally known as Knight Admiral #TC-9527, Kalo is the best friend of Careful S. and his companion in battle. and the other four superheroes of Planet Xing. Originally from Planet Adeli before its destruction. Can turn his own bodyparts into inanimate objects as well as controlling electronic objects. His body is composed entirely out of energy, as signified by the flames. Therefore, as we learn in Season 7, when he uses more energy, he is literally burning his lifeline.- Barbie Doll Anatomy: Thankfully, considering he never really wears clothes.
- Bash Brothers: with Careful S.
- Big Brother Mentor: Primarily to Careful S, but also to the rest of the alliance. His mature and knowledgeable side is specifically displayed in early episodes of season 11 through the advice he gives.
- Which is somewhat logical for the producers to assign him the Mentor Occupational Hazard.
- Chest Insignia: An inverted triangle (Nabla) just below his chest. Careful S. later adopts the triangle into his own symbol in Season 10, possibly to solidify and bear in mind Kalo's sacrifice and legacy .
- Companion Cube: A variant; Kalo becomes Careful S.'s Rubik's Cube not long after they meet for the first time in Season 3, due to the events of Kalo's premiere episode leading to Careful S.'s original Rubik's Cube breaking.
- Cool Shades: He is often seen wearing a pair of black shades.
- Exposed Extraterrestrials: He’s an alien when compared to the rest of the main cast and he wears nothing but a visor (though the new art-style gives him a pair of white boots).
- Faceless Eye: His debut episodes have him frequently morphed into a Cephalothorax body shape that has a single eye for a face. He stops using it later on.
- Flaming Hair: Sort of. Kalo has blue energy flames on the top of his head where hair would normally be.
- Heavenly Blue: Related to his title of "Zhan Shen" (God of War) to Adelians.
- Honor Before Reason: A flaw of his back in earlier episodes, due to coming from a military-based planet. He grows out of it.
- Military Superhero: He was in the military pre-series.
- Not Afraid to Die: In fact, he does this for the greater good of planet Xing Xing in Season 7 - he kills himself to drive away an army of enemy spaceships.
- Older Than He Looks: Kalo is confirmed by the creators to be around 30 (see also Season 9). The animation style, however, does not particularly reflect that in a visual aspect. May be justified as he's an alien from Planet Adeli and the way he ages may be different from that of the other characters.
- Put on a Bus: Since his ultimate death in season 7, and until his revival in Season 10, he only appears once physically in Season 9, Episode 13, when his 25-year-younger-self is scouting a crime scene with Careful S. (Sadly, Careful S. does not recognize him, since he has a human disguise on.)
- Shout-Out: His formal name is Knight Admiral #TC-9527. The number 9527 comes from the Hong Kong movie Flirting Scholar (唐伯虎点秋香), where the main character disguises as slave #9527. One of the screenwriters of Happy Heroes at the time snuck in the reference because they really liked the film.
- Sixth Ranger: He's the only non-Superman of the main team and isn't established to be one of them until Season 3, and he initially doesn't make nearly as many appearances as the other team members.
- Technicolor Fire: His fire "hair" is blue.
- Token Non-Human: The Supermen are human-like robots rather than, y'know, actually humans, but Kalo is still the only person on their team who is very distinctly alien to their planet.
- Trademark Favorite Food: Seems to be watermelons, as an official illustration made for his birthday and a scene in Season 5 episode 22 show.
- Voluntary Shapeshifting: Part of his powers. Major forms include; his normal one, the Cephalothorax one he takes in earlier episodes, a jet-pack, a sword and a Rubik’s Cube.
People of Planet Xing
Doctor H. (Zhai Boshi/Doctor Zhai)
The nonbiological father of the five superheroes of Planet Xing, and a mechanic who prefers to stay inside his house.
The H. stands for House, if you were wondering.
He is present in Season 9, but as a 25-year-younger-self, who just lost his father; known as Little H.

- Papa Wolf: Despite knowing that they can protect themselves, he still occasionally acts like this towards the Superheroes. For instance, during episode 52 of Season 1, he jumps between them and a giant robot. While injured.

- Proud to Be a Geek: His knack for inventing things and crush on news reporter Miss Peach seem to indicate he's geeky. Indeed, in the first movie, he has no problem calling himself a "total geek" and it's mentioned that he was nominated to be the Geek Association's President.
- Single-Target Sexuality: He never strays from having a crush on Miss Peach.
- Technological Pacifist: He creates a wide variety of non-weapon things.Doctor H.: Why does it have to be a weapon? The same materials could be used to create things useful to people!

Appears in Season 9 as her 25-year-younger-self; known as Peach.- Captain Ersatz: Many of her features are dead ringers for Princess Peach from Super Mario Bros.. She has a heart-shaped bang, she has blonde hair, she wears a pink dress, at least one major character has a crush on her... oh, yeah, and her name is also Peach.

- Improbable Hairstyle: She has the front of her hair done up in a heart shape that must require a lot of work to keep in that shape.
- Hair of Gold, Heart of Gold: Miss Peach is a very kind woman who has blonde hair.

Mr. Lightbulb
The headmaster of planet Xing Xing's television studio. Appears in Season 9 as his 25-year-younger-self; known as Lightbulb.- Money Fetish: He'll do anything from forcing Product Placement into the shows he hosts to outright resorting to Very False Advertising to make a quick buck.

Mr. Lightbulb's son; he goes to the same school as the Heroes.Villains
Big M. and Little M.
Little M. is on the left, Big M. is on the right.
Tropes shared by both characters:
- Big Eater: The two rarely get to eat anything, so whenever they do find food, they usually scarf it down pretty quickly.
- Big Guy, Little Guy: Big M. is the big guy and Little M. is the little guy.
- Evil Duo: Big M. is the one who masterminds the plans to take over Planet Xing, and has some level of competence compared to his corporal assistant Little M., who often catches Big M. off-guard with his weirdness, probably since he's literally a child.
- Master of Disguise: Big M. and Little M. frequently take on a number of paper thin disguises - from salesmen to a mother and child to Sailor Moonnote of all people in Big M.'s case - to perpetrate their evil plans, and they have a tendency to work, convincing even the Supermen.
- Unknown Rival: With at least one exception in Season 8 where Sweet S. nearly discovers Big M. is a villain before Huo Haha manages to convince her otherwise, the Supermen are completely unaware that Big M. and Little M. are trying to invade their home planet and send out most of the monsters they fight - even if the evidence is right there in plain sight. It isn't until Season 13 when the Supermen finally learn of their former plans to invade Planet Xing.
Big M.
The first major antagonist of the show. He makes all of the attempts he can to get back to his home planet, Planet Gray, but he inevitably fails. He also tries to take over planet Xing Xing often. In Season 9: his teenage-self.- Aliens of London: The Miao Mi English dub gives him a noticeable British accent for a few episodes.
- Big Bad: He is primarily responsible for the bad happenings on planet Xing Xing for a good part of the series, being responsible specifically for unleashing different monsters on Xing Xing's residents.
- Butt-Monkey: The show loves to put him through slapstick and embarrassing situations.

- Domino Mask: Big M. wears a mask of this kind.
- Early Installment Character-Design Difference: In the first two episodes, he has two spiky shoulder pads on his green suit of armor that disappear starting from the third episode. The Planet Gray symbols on his headband and belt also do not have antennae in the first two episodes.
- Evil Brit: A small handful of Miao Mi's English-dubbed episodes give him a British accent.
- Evil Is Bigger: His name is Big M., for starters. While he's not especially large, he is slightly taller than most human characters and robots you can find on Planet Xing. In fact, in Season 10, they made him even bigger, and in the third movie he's bigger still. Little M. is over half the length of Big M. when the series begins; in Season 10, he's half the length instead; and in the movie, Big M.'s length is equivalent to about three Little M.'s placed on top of each other.
- Evil Is Hammy: He has a more exaggerated, hammy voice in the Lookus English dub.
- Expressive Accessory: The Planet Gray insignias on his headband and belt have faces that often make different facial expressions depending on what face Big M. is making.
- Gonk: Big M. is deliberately made to look ugly, with his puffed-up lips and zig-zagged mustache. In-universe, he's so ugly that anyone who looks right at him throws up on the spot.
- Green and Mean: He's the primary antagonist of the show and wears a suit of green armor.
- I Was Quite a Looker: As shown in Season 3 episode 20 and Season 9, he was once a dashing young fellow with an IQ of over 200. Then he got hit in-between two elevator doors. Repeatedly.
- Improbably High I.Q.: Before he got slammed in the face by elevator doors and became his current self, Big M. had an IQ of over 200.
- Maker of Monsters: In numerous seasons, Big M. has some kind of device at his disposal to create monsters. In Season 1, he has the Black Jewel, which has the ability to turn objects into monsters; in Season 2, he has the Evil Egg, which creates an object that turns another object into a monster if it touches it; and in Season 5, he has the Planet Gray virus to infect people and turn them into monsters against their will.
- Red/Green Contrast: Big M. is a villain in green armor, contrasting with Happy S.'s heroic red color scheme.
- Share the Sickness: In "Sickness Crisis", Little M. catches a cold, giving Big M. the idea to spread it across planet Xing, and getting himself infected as well for more ground coverage
- Shoulders of Doom: In the first two episodes (and only the first two episodes), his armor has two shoulder pads with spikes on them.
- Spikes of Villainy: In the first two episodes, anyway, where he has two spiky shoulder pads on his green suit of armor. These shoulder pads disappear starting with episode 3.
- Superheroes Wear Capes: Inverted. Big M., a villain, wears a cape, a feature that the Supermen don't have.
- Terrible Artist: As shown in Season 8 episode 12, where he tries to draw a door and winds up with what looks more like a hole. Little M. has to go find an art teacher to give him lessons on how to draw better, and by the time the lessons are over he's able to draw a Fourth-Wall Portrait of a live-action human with ease.
Little M.
Big M.'s assistant, who helps him in his attempts to get back home or take over planet Xing Xing.- Brought to You by the Letter "S": In the third movie, his helmet's default display is an "M" on its screen.
- Butt-Monkey: Not as much as Big M., but he still gets put through awkward situations.
- Enfant Terrible: He's young enough to be in the same classroom as the Supermen and takes interest in helping Big M. take over Planet Xing.
- I Was Quite a Looker: He’s still cute, but Season 3 episode 20 shows that was quite handsome before being hit by elevator doors.
- Plucky Comic Relief: He provides most of the comedy in any scene featuring him and Big M.
Major Antagonists & Monsters
The Commander
The commander of Planet Gray's military. His face is never shown on camera; he usually has his back to the audience or has his face covered.- The Faceless: His face is completely obscured from view whenever he appears. In Season 12, we do get to see some of his face; he has a big bushy mustache, but his eyes are still obscured from sight due to a shadow coming from his hat.
- Good Smoking, Evil Smoking: He's one of the villains from Planet Gray and is often seen holding a cigarette in his hand.
- Orcus on His Throne: He's never seen doing much outside the chair he sits on.
Daoliu Dun
A military leader of Planet Daoba; he tried multiple times to conquer Planet Xing.Caesar
An Adelian who played a part in the destruction of his home planet. Helped Daoliu Dun attack Planet Xing, and played a role in Kalo's ultimate death in Season 7.- Exposed Extraterrestrials: Being an Adelian, he wears nothing but a visor, as well as a cape (though model sheets featuring the new art-style give him a pair of white boots).
Shapeshifter/Transformation M.
The monster from the 1st Movie; it was shown that they wanted to be an inventor.- Ambiguous Gender: They're not referred to with gendered pronouns for any of their appearances.
- Canon Immigrant: Their first appearance is in the first movie, but they later make an appearance as a minor antagonist in Season 9.
- Voluntary Shapeshifting: Obviously. He mainly takes the form of Doctor H., and is shown to mimic his behaviour so well, it fools even the Heroes at first.
Huo Haha
A magician who worked for Planet Gray; he owned a book written by his ancestor Xiao Haha, which was about the old days when magic was still prevalent, and competed with the heroes in finding the four magical staffs: Fire, Wind, Electricity, and Ice.
- Affably Evil: He works for the villains Big M. and Little M., but has a heart of gold and genuinely cares for others.
- Alliterative Name: His name repeats the letter "H".
- Animal Motifs: It's not touched upon much, but based on part of his hood forming a beak-like shape and him owning a pet owl, he seems to be associated with owls.
- Arc Villain: In Season 8, he has the closest personal connection to the History of Magic book and the elemental staffs Big M. and Little M. want to use to kill the president. Makes sense, since his ancestor Xiao Haha is the one who wrote the book and used it to contain the staffs in the first place.
- Even Evil Has Standards: Played for Hypocritical Humor. Huo Haha is genuinely interested in killing the president of Planet Xing, but has problems with things being too unethical for his tastes. Killing the president of Planet Xing is clearly not ethical, so most of his problems are insignificant in comparison: he thinks his evil laugh is too scary for the Supermen and apologizes for it, and insists on being quiet in a library, for example.
- Fireballs: He shoots fireballs from his toilet plunger wand on a couple of occasions to attack the Supermen.
- Identical Grandson: Though it's only made clear that Xiao Haha is Huo Haha's ancestor and it's never mentioned if he's his grandfather specifically, in many ways, the two still resemble each other quite a bit, with one of the main differences being that Huo doesn't have a beard like Xiao.
- Improbable Weapon User: His toilet plunger makes a surprisingly competent magic wand.
- Lunacy: As shown in Season 8 episode 33, he absorbs moonlight to power his magic. This causes his powers to weaken when he casts an Endless Daytime spell.
- Mad Libs Catchphrase: He prefaces some of his magic spells with "Huo huo, ha ha, [intended effect of the spell]!"
- Magic Wand: He uses what is clearly a toilet plunger to cast his magic spells.
- Magical Incantation: Quite a few of the magic spells he uses are prefaced with "Huo huo, ha ha, _____!". The blank is where he says the intended effect of the spell.
- Perma-Stubble: Huo Haha has a noticeable stubble on his chin.
- Red Eyes, Take Warning: His pupils turn red when he's in his superpowered form from using all the elemental staffs in Season 8 episode 40.
- Token Wizard: Any time he's working alongside Big M. and Little M., he's the only wizard out of the villains.
- Unfortunate Names: The fact that his name sounds like laughing seems like something that would lend itself to actual laughs at his expense. This is directly lampshaded in the first episode of Season 8 by way of a Who's on First? joke when Big M. and Little M. meet him for the first time.Huo Haha: Hi. I'm the magician who attacked the president, Huo Haha!(Big M. wallops Huo Haha, resulting in a Hit Flash and a Cranial Eruption on Huo.)Big M.: Enough! Do you think I was joking? Be serious!Huo Haha: But I didn't laugh. My name is Huo Haha.
Tropes shared by Moondance and Starshadow:
- Red/Green Contrast: Moondance has bluish-green hair and bluish-green accents on her outfit. Starshadow has red hair, and his outfit is predominantly red and black.
- The Power of Rock: They summon their monsters by shouting/singing into microphones.
- Rotten Rock & Roll: They're villains, and shouting into microphones rock-and-roll style is how they summon monsters.
- Stellar Name: Yuewu's name translates to Moondance, and Xingying's name translates to Starshadow or Shadowstar, both with celestial theming in them.
Yuewu (direct translation: Moondance)
- Aw, Look! They Really Do Love Each Other: Despite acting cold most of the time, she does have moments where it’s clear she does care about Shadowstar.
- Action Girl: She’s good with those giant chopsticks, although she’s good with hand-to-hand too.
- Big Eater: She eats a lot, once being shown having eaten several bowls of noodles at a restaurant. Whenever she finds food, she will eat it too.
- Improbable Weapon User: A pair of giant chopsticks.
- Odango Hair: Wears her hair in this style. They have chopsticks stuck in them.
- Plot Allergy: To mango, as shown when she breaks out in hives when she eats a pudding containing it.
- Taking the Bullet: For Starshadow, in Season 13. Kind of an Idiot Ball moment though…
Xingying (direct translation: Shadowstar/Starshadow)
- Affably Evil: Shows signs of this compared to the more cold Moondance, once challenging Happy S. to a friendly noodle-eating contest.
- Fiery Redhead: His hair is red and he’s definitely a lot more energetic when compared to Moondance.
- White Hair, Black Heart: Later seasons have his hair be a pale blonde colour.
Other
Notable Minor Characters
Zelia (Zhanglang: Cockroach)
A minor character in the series. Zelia appeared only in a few episodes: she was introduced in Season 1, appeared in some episodes in Seasons 3 & 4, and one in Season 5. She also appeared in the 2nd movie.- The Bus Came Back: She finally reappears in Season 12.
- Disney Death: In the 2nd movie. It sent Happy S. into a Heroic B So D for sometime.
- A Dog Named "Cat": A person named Cockroach in at least one translation.
- His Name Really Is "Barkeep": In her debut episode, she calls herself "Cockroach" because she doesn't remember her real name. At the end of the episode, Doctor H. finds a document from her spaceship revealing that "Cockroach" is her real name.
- Ship Tease: Has some with Happy S.
Arcas (Akasi)
He is Kalo's Adeli army friend, and was introduced in Season 3, with two episodes. He appears a few more times after: two episodes, in Season 6, and in the Season 7 arch when Kalo dies. Seen again in a memory of Kalo recounting his encounter with Thunder M.- Arm Cannon: His weapon of choice, possibly to contrast with Kalo’s swords.
- Childhood Friends: Is this to Kalo.
- Exposed Extraterrestrials: Being an Adelian like Kalo, he wears nothing but a visor (although the new art-style gives him a pair of white boots).
- Fiery Redhead: A literal example. The flames coming out of his body are coloured red. He’s also quite dramatic.
- Frame-Up: For stealing important documents, by Kalo, to prevent him from getting into the Adelian Guard. He had a good reason for doing this though.
- Human Popsicle: More like “Adelian Popsicle”. He, along with his ship, was frozen in ice after he crashed on Planet Xing Xing when his ship malfunctioned . In episode 12 of Season 3, Big M. and Little M. come across him after yet another scheme goes wrong and end up accidentally breaking him out.
- Harmless Freezing: It’s unknown exactly how long he was frozen for, but when he breaks out, he’s completely fine, not even needing the bathroom.
- The Scapegoat: Caesar was planning to push the blame for his treachery onto him, leading Kalo to do the Frame-Up mentioned above.
- We Used to Be Friends: Kalo and him were friends growing up, but after Kalo had him framed and put in jail, he formed a hatred for him. They repair their friendship after Arcas finds out about why Kalo did it (and also that he saved his parents).
- Would Hurt a Child: He set a kindergarten ablaze to lure Kalo out, and (along with Big M. and Little M.) had the kids tied up over a bunch of gasoline cans.
Planet Guling
The Village Mayor
The mayor of the village that the Heroes stay in.Aqiang
Buding
The Village Mayor's daughter. It was found out in the Season 6 arc that she was actually a robot.Qiuqiu
Buding's pet dinosaur.- Waddling Head: Qiuqiu is nothing more than a round sphere shape with stubby claw arms, feet, and a tail.
The Guling Supermen in general
- Fire, Water, Wind: Suspicious S. can shoot fireballs, Sad S. can weaponize her tears, and Sick S. can use winds and tornadoes to attack.
Oversensitive Superhero (Oversensitive S./Suspicious S./Hero Duo)
- The Bus Came Back: He reappears, along with the other Guiling Heroes, in Season 11.
- Captain Patriotic: His love for Planet Guling can be displayed as the other two superheroes literally had to drag him away, under the orders of the Village Mayor, when the planet was under crisis in Season 11.
- Chest Insignia: A large, yellow, upside-down triangle.
- Improperly Paranoid: His main character trait is that he has the tendency to overreact and jump to conclusions way too easily. He opposes the Xing Xing Heroes for a time due to this.
- Playing with Fire: His main power. He usually shoots small fireballs from his hands.
Sad Superhero (Sad S./Hero Shang)
- The Bus Came Back: She reappears, along with the other Guiling Heroes, in Season 11.
- Chest Insignia: A heart with a crack down the middle. Oddly, unlike other heroes with both head and chest insignia, the colour of it doesn’t match the one on her head (the one on her head is pink, while the one on her chest is neon green).
- The Eeyore: Quite morose as evidenced by her name.
- Ocular Gushers: She weaponises this.
- Prone to Tears: As part of her frail nature.
- The Smurfette Principle: The only girl in the Guling Heroes.
- Water Is Womanly: She represents water of the Guling Supermen, whose powers correlate to different elements, and her kind-hearted but emotional personality can easily be considered feminine.
Sick Superhero (Sick S./Hero Exin)
- Blow You Away: He can create tornadoes and winds as his attack.
- The Bus Came Back: He reappears, along with the other Guiling Heroes, in Season 11.
- Chest Insignia: A blue X-mark.
- Flat Character: Not focused on all that much compared to his partners. All we really have is that he’s a germaphobe… And that’s it, basically.
- Terrified of Germs: To the point where he needed a special suit to save a child in a mud pit.
The Robo-King
- Adipose Rex: He has the appropriate name and getup for royalty, and much of his bulk forms a cephalothorax-esque shape, with the only thing distinguishing him from a cephalothorax being his head is separate. His arms and legs are also downright stubby.
- Walking Spoiler: He doesn't appear in his debut season until near the finale and he's responsible for introducing technology to Planet Xing, clearly indicating that his plot relevance is meant to be a surprise.
Season 7 Characters from Planet Wangcai and Planet Miaomei
Tropes shared by the inhabitants of both planets:
- Alien Animals: The Woofians are alien dogs and the Miaolings are alien cats.
- Animal Jingoism: The doglike Woofians and the catlike Miaolings are rival races.
- Funny Animal: They're races of anthropomorphic dogs and cats that have the more animalistic features of both (the cats have retractable claws, the dogs sit on all fours, both species have stereotypical diets of bones and fish, etc.).
- Humanlike Hand Anatomy: Both races have the standard Four-Fingered Hands instead of the paws that actual dogs and cats have.
- Planet of Hats: Planet Wangcai/Planet Woof is a planet of dog aliens, while Planet Miaomei/Planet Miao is a planet of cats.
- Stock Animal Diet: The doglike Woofians like to eat bones, and the catlike Miaolings like to eat fish.

Lele
- The Prankster: In his first physical appearance (S7E3, "Troublesome Seatmates"), he uses a joy buzzer while shaking the hand of one of the Supermen and says he's a master prankster. Before that, in the first episode of Season 7, by the time his mother Ambassador Wang has arrived on Planet Xing, he's doodled a fake mustache on her while she was sleeping.
