Alter-ego: Dave Lizewski
- The Ace: He's not one, but Justice Forever gladly accept his offer to join the team based on his reputation as one. Although he is one of the more competent and likely the most experienced heroes.
- Atrocious Alias
- Casual Kink: His superhero obsession is presented as such. Unusually for such a... weird fetish (but in line with the trope), it's shown to be a healthy outlet for his fantasies, since said fantasies involve community activism and an altruistic outlook on life and society.
- Determinator: Perhaps the only real power he possesses is the fact that he never, ever gives up. Even when he gets strapped to a chair and gets his testicles electrocuted for half an hour, his plan for getting out of it is to get the mobsters to punch him until the chair breaks. Then he gets right back up and tells them to bring it. They do, but luckily Hit Girl returns just in time to eviscerate them all. Which is either pretty solid deconstruction or straightforward Badass. The fact he keeps at the whole superhero thing even when he knows full well that the world's not worth saving is supposed to be a gut-wrenching demonstration of the kind of depths of despair and nihilism he's fallen to, but it reads more like a very well written Moment of Badass.
- Did Not Get the Girl: After months of pretending to be her gay best friend, he finally bares his soul to Katie Deuxma. Expecting her to reciprocate his feelings, Katie instead gets her boyfriend Carl to beat the crap out of him and later sends him a pornographic picture of herself with said boyfriend, which Dave later uses.
- Disability Superpower: His high pain threshold is due to nerve damage.
- Disproportionate Retribution: In Volume One, he leads with violence, in the face of non-violence. In particular, during his first foray into vigilantism, he brutally ambushes some young graffiti artists. Although he loses the battle, there's no indication that what he did was immoral. And this would lead to Unreliable Narrator - it's the perpetrator that's narrating the story. And the narrator is a supremely bored high schooler.
- Feel No Pain: As a result of nerve damage sustained during his first failed attempt at being a superhero, this could be considered the closest thing he has to a superpower. Even then he can feel some pain.
- Freudian Excuse: His Good Is Not Nice personalities stem from the fact that his mother had died.
- Jumped at the Call: At the end of the comic trilogy, Dave reveals that he became a cop after immediately joining Marcus's recruitment drive for a rejuvenated, newly-cleansed NYPD.
- Made of Iron: Hand Waved by his dulled nerve endings but that fails to explain how he shrugs off the damage from repeated electric shocks and multiple beatings without requiring a lick of medical attention. The various pins and metal plates he got after the car accident would account for some of his resistance to injury, though this has clearly been turned Up to Eleven.
- Memetic Badass: An in-universe example. Even though the clip clearly shows him being terrible at being a superhero, because he refuses to give up the fight, he becomes so popular that he inspires a comic based on himself as a legitimate superhero along the lines of Green Arrow or Batman.
- Memetic Mutation: In-universe. The fruit of his efforts to rescue people, which ends up as a Youtube video internet sensation? People cosplaying as superheroes and taking pictures of themselves, which now goes past the hardcore geeks and to everyday people. Plus, a whole bunch of them actually start training to be superheroes like him, Big-Daddy and Hit-Girl.
- Mistaken for Gay: Happens to him after he gets beaten up twice while trying to be a real-life superhero, with the kids at school assuming he's a gay prostitute who keeps getting beaten up by his clients. He goes along with it for a while since his crush, Katie Deauxma, adopts him as a gay best friend. The situation does not end well. After acting the part of the Gay Bestfriend (including spray tanning her topless), he admits it was all a ruse. Katie is furious, and has her boyfriend beat him up, followed by a graphic photo of their sex sent by phone.
- Ordinary High-School Student: Supposedly. He makes it very clear in the beginning that there's nothing special about him that would lead him to become a superhero. He just does it because he's bored. But he makes the case that he's so ordinary by listing a bunch of things that normal high-schoolers do and then pointing out that he's ordinary because he doesn't do any of them.
- Parental Abandonment: His mother died of aneurysm some time before the start of the story. His father is later killed by Red Mist's goons after claiming to be Kick-Ass in order to prevent Dave from going to prison.
- Reality Ensues:
- A teenager with no powers or special training decides to become a superhero. Especially when he fights crime for the first time he ends up getting stabbed by one of the thugs.
- Then subverted by...most of the comic after that point. To start with, getting stabbed and hit by a car gave him just enough, very specific nerve damage to stop feeling almost any pain.
- Spandex, Latex, or Leather: He goes with a wetsuit. He gets harassed by two girls for looking like a gimp, before he comes across the beating that gets him famous.
- Tap on the Head: He gets smacked around so hard he needs a steel plate in his head. After much, much healing the plate somehow provides a limited amount of impact-to-skull protection. Although it's not that the plate provides protection so much as he's already suffered sufficient nerve damage that hitting him there won't do any more.
- This Loser Is You: He is a pathetic, sometimes egotistical, American comic book nerd trying to be a superhero, who starts off getting his ass kicked, constantly humiliates himself and only manages by sheer luck and the intervention of the more successful heroes, Hit-Girl and Big Daddy. His crush only pays attention to him because she thinks he's gay, and when she finds out he's not, she tosses him aside, after he gets beat up by her boyfriend and left with a picture of her going down on said boyfriend for him to wake up to.
- Took a Level in Badass: In Volume 1, he was absolutely pathetic in a fight. In Volume 2, he receives Training from Hell from Hit-Girl and learns how to actually fight. Heck, during his team-up with Doctor Gravity, he effortlessly beats the tar out of two hoods (something he couldn't even do in the first issue of the series), and this is before Hit-Girl's training! In Volume 3, he holds his own against 6 thugs, two of whom were holding guns to his head at the start. Though he eventually loses, he points out his one mistake immediately after the fact, implying that he was capable of taking them on a good day.
- Tuckerization: He was named by the winner of a contest, who chose his own name, essentially Tuckerizing himself.
- Wangst: In-universe. Due to this, he keeps swinging back and forth between deciding to become a superhero to not. Then it comes to a head when he realizes he's just spawned a new force of incredibly violent vigilantes, and he's not taking it well.
Alter-ego: Damon McCready
- Ascended Fanboy: He is a massive comic book geek who financed his vigilantism by selling classic comic books like Amazing Fantasy #15...
- Awful Truth: He is not an ex-cop whose wife got killed. In fact, he was an accountant whose wife hated him so much that he decided to run off with his baby daughter and start a new life as a superhero.
- Captain Ersatz: Of The Punisher, minus the skull. And tragic backstory, it turns out.
- Charles Atlas Superpower: He is capable of crazy stunts and incredible exploits by virtue of good ol' training and perseverance.
- Crusading Widower: He trains his daughter to get revenge on the drug lord who murdered his wife. It's a lie: she's really alive and he made the whole thing up to brainwash his daughter into becoming a vengeful superhero out of boredom with his pathetic life.
- Evil Parents Want Good Kids: Subverted. Despite looking like Ned Flanders, he raises his little girl to be a ruthlessly efficient vigilante in order to exact revenge on John Genovese not really revenge, he was just bored with his life and wanted his daughter to have an interesting life.
- Expy: He is basically The Punisher with a badass little girl sidekick, Lampshaded when Dave compares him to Frank Castle. He and Hit-Girl are also similar to Cassandra Cain and her father in that, in spite of being trained to be a killer by him, still loves him.
- This Loser Is You: He is revealed to be a comic book fan himself instead of being an ex cop, and is depicted as a pathetic loser who decided to become a superhero and train his daughter to be one after his marriage broke down.
Alter-ego: Mindy McCready
- Berserk Button: Do not threaten her mother or Marcus. Of the four hitmen, three were sliced open and the fourth was killed with a sledgehammer (she wanted to use something special for him). And Ralph Genovese, who sent the hitmen... He was the final victim of Hit-Girl's horrifically epic Roaring Rampage of Revenge.
- Big Damn Heroes: She pulls this after she disappears by being shot and falling into the water. The mobsters assume that No One Could Survive That, and assume she's dead. This allows her to sneak up on them just in time to save Kick-Ass from getting killed.
- Charles Atlas Superpower: She is capable of crazy stunts and incredible exploits by virtue of good ol' training and perseverance.
- Child Soldier: She is a strange case, because not only is she aware of her status as this, but she's far more capable than the 16 year old title character. Also, in a realistic twist on the trope, the bad guys have absolutely no problem with trying to kill her. The two most heinous examples are when they shoot her in the back with "a hundred bullets" (which she recovered from) and whacking her in the head with a meat hammer. To be fair, however, she had already done much, much worse to them. After her father gets killed, Kick-Ass helps her track down her mother, and she goes back to a normal life like nothing bad ever happened. The first issue of Volume 2 shows her continuing to train Kick-Ass, keeping a small army's worth of firepower hidden in her bedroom, and being thoroughly bored with civilian life. So her normal life is probably going to just be a temporary blip.
- Clean Cut: Her swords are implausibly sharp for a comic that claims to be set in reality. There's also the fact that even a grown adult wouldn't be able to generate enough force to cut through bone in one swing (at least with those weapons), let alone a ten year old girl.
- Conditioned to Accept Horror: She has no qualms about vigilante murder and even killing mooks for money. She has been trained by her father to be a killing machine because he wanted a more exciting life.
- Cute Bruiser: A ten-year old vigilante who can kick 7 kinds of ass with a variety of weapons.
- Deceptive Legacy: Big Daddy tells her that her mother was killed by the mob, fuelling their Roaring Rampage of Revenge against the Genovese family. It's revealed however, that her mother is very much alive, and Big Daddy simply snuck off with her when she was an infant, so he could raise her to be Little Miss Badass and live out his fantasy of being a vigilante superhero. After Big Daddy is killed, she goes back to her mother, who had been searching for her for years.
- Enfant Terrible: While in her civilian garb she plays off as an innocent little girl, but outside of this, due to Training from Hell from her father, she is incredibly skilled with any weapon but she favors swords and knives in particular and can slice through an army of thugs in minutes and can shatter a man's leg with a single kick. She does all of this with sadistic glee, and she's one of the good guys.
- Expy: She and Big Daddy are similar to Cassandra Cain and her father in that, in spite of being trained to be a killer by him, still loves him.
- Freudian Excuse: Her Good Is Not Nice personalities stem from the fact that her mother had died.
- He's Back: Having spent the first four issues of Volume 2 trying to be normal, she steals a cop's gun & guns down Red Mist's Mooks after they set-off a bomb & kidnap Dave at his father's funeral.
- Homeschooled Kids: She didn't go to school and was raised as a Tykebomb by her dad. She does join a school at the end of Volume One, after her father bites the dust and her nemesis is defeated.
- Improbable Age: An eleven years old Badass with Charles Atlas Superpowers? If it wasn't so awesome it would have really stretched the Willing Suspension of Disbelief.
- Knife Nut: She adores butterfly knives and swords, although she is a pretty good shot as well.
- Little Miss Badass: She is an 11 year-old girl with a lock for a symbol and a katana, who annihilates a room full of baddies in her first appearance.
- Reality Ensues: Unlike other Tykebomb-turned-superheroes in other media, Mindy is clearly damaged by her upbringing as Hit-Girl, escalating into disturbing hallucinations of her Father still giving her orders and advice.
- Sanity Slippage: Issue #5 of Hit-Girl shows her having Hallucinations of Big Daddy, who advises her to go out and slaughter Ralph Genovese and the rest of his men in the horrifying ways that she'd been planning.
- Training from Hell: One of her lessons consists of her father shooting her just so that she knows what it feels like, when she’s only ten years old.
- Troubling Unchildlike Behavior: If you are in any way associated with organized crime, she will brutally chop you up and shoot you in the head while cursing like a sailor. She's a cute 10 year old.
- True Companions: With Kick-Ass, after her dad died. He's pretty much the only person she opens up to at all, and cares dearly for his well-being. He's also her go-to sidekick in the second volume.
- Tykebomb: Her backstory was that she was over-trained at an early by her vigilante-minded father to grow up akin to Batman. Though it must be considered that the "defected cop whose wife was murdered" story was made up by Big Daddy. The motivation for turning his daughter into a killing machine was not revenge, but simple fun.
- Walking the Earth: At the end of the comic trilogy, she cuts all contact with Dave, though he heard rumors that she went crime-hunting in Italy and Britain.
Red Mist/The Motherfucker
Alter-ego: Chris Genovese
- Alas, Poor Villain: He dies saving Mindy and asking her to apologize to his mother for ruining her life.
- Ascended Fanboy: He is a massive comic book geek, even though he wants to be the villain.
- Atrocious Alias: In Volume Two, he changed his name to the Mother Fucker, and named his gang The Toxic Mega-cunts.
- Big Bad Wannabe: Dave initially scoffs at the idea of Red Mist being out for vengeance against him. While he does commit a whole bunch of horrible crimes in volume 2, such as raping Katie, arranging the murder of Dave's father, and is now planning to bomb the entire city of New York. He's only able to pull them off because he's paid off a bunch of other supervillains to protect him. When Dave finally confronts him it turns out that Mist hasn't bother training to fight at all, at which point he is promptly beaten within an inch of his life.
- Color Character
- Disproportionate Retribution: What he does to destroy Dave in Volume Two. Unmasks him, murders Katie's parents and rapes her, kills his dad, and bombs his funeral.
- Even Evil Has Standards: Averted in Volume 2, Issue 4, when he guns down a group of children. Then proceeds to kill the main character's love interest's mother and father and gang rape her with 2 of his henchmen. Though one could argue that the way the first volume ended she wasn't an entirely sympathetic character at that point. On the other hand, the book doesn't make any effort to justify her rape.
- Evil Counterpart: He is this to Kick-Ass. While Dave was inspired by the heroes in the comics, Chris was inspired by the villains (even quoting The Joker before setting up his Avenging the Villain story-line in Volume Two).
- Heel Realization: In Volume 3, he realizes that his his mother, whom he genuinely loved, tried to kill him in his hospital bed because his horrible spree ruined her life. He felt so guilty for causing her so much anguish that he has a Heel-Face Turn, does his best to help his former enemies Hit-Girl and Kick-Ass and dies for his efforts.
- Kick the Dog: In Volume 2, Issue 5, he has Dave's father, who handed himself over to the police as Kick-Ass in Dave's place, killed in prison just so that they'll be able to kidnap Dave at the funeral.
- Laser-Guided Karma: After Red Mist is revealed as The Mole, Kick-Ass soundly beats the shit out of him the first chance he gets, and without much effort to boot. And this is pre-Took a Level in Badass Kick-Ass, for those keeping track.
- Late-Arrival Spoiler: If you saw The Movie Adaptation first, it comes as no surprise that he is The Mole. And don't even mention the trailers for the second movie showing his ascension to Big Bad.
- Redemption Equals Death: He dies saving Hit-Girl from corrupt cops, but not before he asks her to apologize to his mother on his behalf for traumatizing her with his crimes.
- Took a Level in Badass: Averted and lampshaded in Volume 2. Before killing Colonel Stars, Red Mist says he was going to travel the world and learn martial arts... until he remembered he was rich and could just pay other people to do his fighting for him. That and his trainers were swindling him, with a 'task' ripped off Batman Begins because it looked cool.
- Used to Be a Sweet Kid: Volume 3 reveals that as a child, he used to be a fan of X-Men to the point where he would dress up as Wolverine on a daily basis.
- Alas, Poor Villain: Sort of. Big Daddy drove him nearly to madness, and all because Big Daddy wanted to live his childhood fantasy and choose him as the villain.
- Meaningful Name:
- His surname is a reference to Kitty Genovese, a woman who was murdered apparently without her neighbors bothering to intervene (the situation may have been more complex, but that was the public perception). This incident is commonly cited as sparking the real-life superhero movement.
- Genovese is also the name of a major Mafia boss/family.
Marty Eisenberg/Battle Guy & Todd Haynes/Ass Kicker
- Blatant Lies: Marty tells Justice Forever a story involving his parents being killed & eaten in front of him to serve as his motivation for becoming a vigilante. Dave immediately sees through it & reveals that it's all a lie.
- Follow the Leader: Marty becomes Battle Guy after being inspired by Kick-Ass, before finding out that his best friend Dave is Kick-Ass; they later bring Todd in on the action & he keeps coming up with names derivative of "Kick-Ass", which Dave & Mart call him out on.
- Forced Meme: They try to bring the word "tunk", conceived of as the Spear Counterpart of cunt, into the mainstream as a new curse word. They succeed.
- Memetic Mutation: In-universe. They made up swear word "Tunk" (the male equivalent of Cunt) which catches on quite faster than Dave imagined.
- Parental Abandonment: Subverted with Battle Guy in Volume Two - his origin story is that his parents were killed on the way home from the opera, and the criminal then forced him to watch as he cooked and ate his parents, then spent all the father's money on pay-per-view porn. However, Dave recognizes the voice of his friend, Marty Eisenberg, whose parents are alive and well; turns out he just thought superheroism would be fun, but (mistakenly) believed Justice Forever wouldn't accept him unless he had a cool background.
- Disproportionate Retribution: She supposedly killed the other bodyguards of the Russian Prime Minister when they accused her at cheating at cards.
- Husky Russkie: Seven foot woman with an eyepatch, arms like utility poles, and a cold, murderous disposition.
