Kick-Ass is a creator-owned comic book series written by Mark Millar and illustrated by John Romita Jr. It was first published in 2008 by Marvel's Icon Comics imprint, spanning eight issues. The story follows Dave Lizewski, an ordinary, unpopular high school student in New York City who, inspired by his love of comic books, decides to become a real-life superhero despite having no superpowers, training, or special abilities. After his first disastrous attempt leaves him hospitalized with extensive injuries, including nerve damage that dulls his pain, he persists and eventually gains internet fame, drawing the attention of more serious and lethal vigilantes.
The comic is notable for its deconstruction of the superhero genre, blending extreme, graphic violence with dark humor and a grounded, cynical take on what would actually happen if an ordinary person tried to fight crime. It explores themes of celebrity culture, the influence of media on youth, and the blurred lines between heroism and vigilantism. The series gained significant attention for its controversial content, particularly the character of Hit-Girl, an eleven-year-old trained assassin whose brutal methods and foul language sparked debate about depictions of child violence in media.
Kick-Ass was a commercial and critical success, cementing Millar's reputation for high-concept, provocative storytelling and further establishing the creator-owned model as a viable path for major comic book creators. The original series was later collected as Kick-Ass: The Dave Lizewski Years, and spawned a sequel series, Kick-Ass 2, as well as a spin-off focusing on a new character, Hit-Girl, and a later reboot series titled Kick-Ass: The New Girl, set in a different continuity.
