!The Heroes

!!Steffi Frohlich/Blitz
The main character of Kiwi Blitz, a 14 year old girl who decides to become a superhero out of boredom, [[HiddenDepths at least at first.]] She pilots the Kiwibot, a mecha designed for robot arena combat, and she is also trained in taekwondo (though not to the extent as her friend Ben). She is very enthusiastic and excitable, and has a habit of rushing into danger, but actually thinks things through better than her allies give her credit for.
!!!Tropes
* AnArmAndALeg[=/=]ArtificialLimbs: Has a robotic leg due to an injury she suffered in early childhood [[spoiler:jumping in front of a bullet aimed at her dad.]]
* BadassAdorable: She's trained in taekwando.
* BilingualBonus: Fluent in German and English (English is her second language).
* BloodKnight: [[DownplayedTrope A rather mild example.]] she participates in public mecha battles even before she became a superhero and clearly enjoys fighting, but she never tries to actually hurt or kill anyone.
* GenkiGirl: When faced with a new mech for her birthday, immediately decides to fight crime in it, and throughout the story seems to dive into situations with relish when she should really be thinking about them. She seems to get the trait from her father, who also exhibits some rather fun-loving tendencies.
* GenreSavvy
* IKnowKungFu
* JumpedAtTheCall
* MistakenForGay
* MissingMom
* NothingIsScarier: Blitz has always worn headphones since she lost her leg. She thought she had died instantly, but as she was fainting from blood loss she found the music in her headphones to be a reassurance that she was still alive.
* RoseHairedSweetie
* SecretIdentity: As Blitz.
* SuperHero
* SuperHeroesWearCapes

!!Benzene Contracter/[[spoiler:Donner]]
Steffi's [[ChildhoodFriends ChildhoodFriend]] and unofficial sidekick. A pretty serious boy and fan of all things military. Pretty skilled at taekwondo and good with computers. He is pretty regularly exasperated by Steffi's actions and seems to have taken it upon himself to keep her out of trouble. [[spoiler:Up to actually joining her as the costumed superhero, Donner, in Track 16.]]
!!!Tropes
* BadassNormal: Took down [[{{Cyborg}} Gear]] on his own with nothing but his martial arts skills, and did it with ''one move.''
** BadassInANiceSuit: What he was wearing when he fought Gear, due to having just come from his birthday party. He took the jacket off though.
* DeadpanSnarker
* HypercompetentSidekick: Ben is the one who feeds Steffi tactical info, is generally portrayed as smarter, and is a better fighter than her hand to hand. But he sticks to the sidelines for the most part since he doesn't entirely approve of Steffi's actions.
* MissionControl: He takes this role for Steffi for the first few Tracks, but later moves takes to the field himself.
* MulticoloredHair: Ben's bangs are lighter than the rest of his hair.

!!Reed Bahia
A policeman in the NYPD, the son of the current Police Chief. Out of all the police shown he is the only one who seems to really want to stand up to the various supercriminals running around causing trouble, and he [[ReasonableAuthorityFigure is always quick to point out that while Steffi is a vigilante, it's the people she's ''fighting against'' who are the real villains.]] [[TheCommissionerGordon Serves as Steffi's one and only ally in the police.]] [[spoiler:He loses his arm in a fight with Gear, and has it replaced with a robotic prosthetic [[SwissArmyWeapon bristling with weaponry.]]]]
!!!Tropes
* AmbiguouslyBrown: From his last name, he is most likely Indian.
* [[spoiler:AnArmAndALeg: Gear cuts off his arm and leaves him alive to try and prove some kind of point.]]
* [[spoiler:ArtificialLimbs]]
* BadassNormal
* FairCop
* PoliceAreUseless: Went into the police force specifically to try and avoid this trope.
* WellDoneSonGuy: Reed's greatest dream as a child was to be a policeman like his father. It's revealed later that Reed's father is the current police chief.
* YouGottaHaveBlueHair: Has green hair.

!!42
A [[DeceptivelyHumanRobot Japanese robot]] sent piece-by-piece to Steffi's father from his roboticist friend in order to avoid anti-robot laws. Since she was just sitting around the house Steffi press-ganged her into helping out with the super heroics.
!!!Tropes
* DeceptivelyHumanRobot: She's designed to look and act human to put people at ease, but WordOfGod makes it clear that she is not actually self-aware, just really well programmed.
* HollywoodHacking
* RobotGirl
* StealthHiBye
* UncannyValley: Not so much art-wise, but explicitly mentioned in-universe on several occasions.

!!Heinrich Frohlich
Steffi's father and owner of the Mecha Machen design and manufacturing company. Kickstarts the plot by giving Steffi the Kiwibot on her 14th birthday. Fully supports his daughter's decision to become a superhero, until she gets herself into actual danger that is. Not a particularly responsible father.
!!!Tropes
* AdultChild
* ArmsDealer: The old family business. Heinrich made changes when he got in charge.
* {{Nerd}}: Has a framed Lord of the Rings map hanging on his wall. It doesn't get much more nerdy than that.
* WearingAFlagOnYourHead: [[IconicOutfit Once wore German Flag colored boxers.]]

!The Villains

!!The Raccoon/[[spoiler:Chandra Makisig]]
A costumed thief who steals on the behalf of a mysterious organization. Definitely a criminal, but seems to be a decent kid for the most part. After Steffi's Kiwibot was captured by the police, she blackmailed The Raccoon into helping her steal it back.
!!!Tropes
* AmbiguouslyBrown:
* BadassAdorable: Not only able to fight Steffi on an even footing, but also took down ''three adult police officers'' when attempting to steal back the Kiwibot.
* [[spoiler:{{Bifauxnen}}]]
* BlatantBurglar
* EvenEvilHasStandards: Refuses to use the grappling hook on Steffi because it could kill her.
** TechnicalPacifist
* GrapplingHookPistol
* HonorAmongThieves: "I may be a thief, but I ain't no liar!"
* PunchClockVillain
* PuppyDogEyes: After getting PunchedAcrossTheRoom by Steffi.
* [[spoiler:SamusIsAGirl]]
* SayingSoundEffectsOutLoud: When Steffi interrupts The Raccoon from eating a sandwich and making "nomph nom" noises, The Raccoon ends up saying one of them.
* StickyFingers
* WhereDoesHeGetAllThoseWonderfulToys: The Raccoon has a TON of gadgets such as the claw hook, smoke bombs, a taser knuckle, knockout patches, and more. It's quite amazing considering that [[spoiler:she's just a young girl.]] It's implied that all of the gear is supplied by a larger organization.

!!Gear
A {{Cyborg}} supervillain who seems motivated purely by boredom and sadism. Robs a bank specifically so that she lure out Blitz for a fight. Half of her body is cybernetic.
!!!Tropes
* AbsurdlySharpBlade: Cuts through the Kiwibot with ease.
* ArchEnemy: [[ConversationalTroping She suggests she is Blitz's, but Blitz denies it.]]
* CardCarryingVillain
* {{Cyborg}}
* EyepatchOfPower: Pretty literally. As in, it's an eyepatch with an "on/off" symbol on it.
* ForTheEvulz
* KnightOfCerebus: She's the first seriously dangerous villain.
* SwissArmyAppendage: Her arm-gauntlet has a big serrated blade inside and is also a gun.
* YoungerThanTheyLook: Steffi mentions that Gear's face is too long for her to be seventeen like she claims.

!!Natrix
A [[LittleBitBeastly snake-like criminal]] who is a member of The Raccoon's organization.
!!!Tropes
* BioAugmentation
* LittleBitBeastly
* NonActionGuy: Ben takes him down without a fight.
* VillainsOutShopping: He's introduced playing Go Fish.
