Heroes and Allies

    The Five Superheroes 

As a Whole

The five main heroes.
  • Kid Hero: One episode reveals them to be in 3rd grade, making them around eight years old, at least mentally.
  • 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.

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.

  • Cute Bruiser: He's an adorable little robot boy... who can and will beat Big M.'s monsters up like nobody's business.

Sweet Superhero (Sweet S./Hero Tian)

The only girl in the team, she is quite smart. Sweet S. can create pink bubbles of any size and resilience (although that will cost her energy) which could float and carry others, and in monster attacks act as shields or super-powered attacks. Starting in Season 9, she can manipulate a Bubble-Man from her bubbles. She also possess the superpower to heal, as seen in Season 11.
  • Barrier Warrior: She often uses her bubble attack to create a shield and block herself and others from incoming attacks.
  • Chest Insignia: A pink-red first aid cross, symbolizes her healing abilities and protective personality.
  • The Heart: Sweet S. literally embodies kindness.
  • Heart Is an Awesome Power: Her main superpower is to create bubbles... which are surprisingly effective as shields, a mode of transportation, etc.
  • 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.
  • 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: In one episode she had to prove to Smart S. that females were as smart as males.
  • You Gotta Have Blue Hair: She has two little ponytails of green hair on the back of her head.

Smart Superhero (Smart S./Hero Hua)

He thinks he is the star of the show, and is very vain. His main ability involves manipulating magnetic fields, therefore giving him the power to create strong magnet links as well as magnetically charged drills. In Season 9, he can attract metals to create armour and limb enhancers, providing him more strength. However, this ability is yet to be showcased in later seasons.
  • Ambiguously Brown: He's the only hero out of the team with noticeably brown-colored skin.
  • Elemental Hair: Has striking, spiky blonde hair, much like his magnetic powers.
  • 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).
  • Narcissist: He tends to refer to himself as stuff like the "main character", and loves to mention how handsome he is.
  • Magnetism Manipulation: Smart S.'s primary superpower is to attract objects with his Smart S. Magnet.
  • Shock and Awe: Electricity is among his powers.
  • Sudden Name Change: From Smart S. to Romeo????

Careless Superhero (Careless S./Hero Chu)

The team's local weapon (mostly guns and anything that explodes) specialist. Does not possess any superpowers except for his prodigy in strategic thinking and enhanced knowledge in weaponry. This makes Careless S. an asset in battle, as he can be very analytical as well as delivering a powerful move via his mobile supply of weapons. However, he can be very forgetful.
  • Adorkable: His tendency to forget things, and has cute little freckles.
  • Simpleton Voice: The Lookus English dub gives Careless S. a much deeper, stupider-sounding voice to accentuate his forgetfulness.

Careful Superhero (Careful S./Hero Xiao)

The last superhero who joins the team, Careful S. may look cold and aloof, but he is actually one of the nicest guys you would ever meet. Has the superpower of creating duplicates of himself, teleportation on high ground, invisibility, and energy manipulation (can concentrate energy to form a laser beam, in a punch or kick during combat, or for energy transfer, healing or in attack form). Very skilled in close-combat, particularly in martial arts and sword-fighting.
  • 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).
  • Cute Little Fangs: The fact that he looks like a cat doesn't help at all with his allergy.
  • Determinator: Careful S. stands for determination and willpower. This is displayed in all seasons, but especially in Seasons 3, 7, 10, and 11.
  • Flash Step: He often gets around by using something like this, where he teleports short distances between given points.
  • 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.



Best friend of Careful S. and 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.

  • Bash Brothers: with Careful S.
    • This is mirrored in Season 9, but the 5-year-oldish Kalo is more of an admirer to Careful S. than an actual partner-in-crime.
    • Therefore, the Red Oni to Careful S, the Blue Oni.
  • 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.
  • 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 .
  • Cool Shades: He is often seen wearing a pair of black shades.
  • Flaming Hair: Sort of. Kalo has blue energy flames on the top of his head where hair would normally be.
  • Fruit of the Loon: In Season 5 Episode 22, Headmaster Tele swears that if he sees a weapon of any kind inside the campus, he will confiscate it. Zooming out of the frame, Kalo is seen transforming his hand into a blade to cut a watermelon. Headmaster Tele, true to his word, then literally confiscates Kalo (along with his watermelon). He's also shown to be fond of watermelons on an illustration made for his birthday.
  • Heavenly Blue: Related to his title of "Zhan Shen" (God of War) to Adelians.
  • 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 They Look: 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.
  • 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.)
  • Technicolor Fire: His fire "hair" is blue.
  • You Gotta Have Blue Hair: Technically he has energy flames for "hair," but it can be considered as hair.
