Lionsgate has premiered the first official posters for Matthew Vaughn’s adaptation of Mark Millar’s comic book Kick-Ass on IGN. The posters come in the form of four character posters, which combine to form the title of the movie.

The mysterious Red Mist is one of the costumed would-be adventurers who emerges in the aftermath of Kick-Ass’ crime-fighting debut. The reefer-smoking Red Mist soon becomes something of a partner to Kick-Ass as their assault on the underworld intensifies, but what is this hero’s true motivation?

Dave Lizewski doesn’t have superpowers, isn’t particularly strong or smart, and isn’t extraordinary in any way… aside from his desire to be a hero. Donning a scuba suit, a ski mask, and a pair of clubs, Dave hits the underworld hard in his new persona of Kick-Ass. Though not as hard — at first anyway — as they hit him when he’s severely beaten and hospitalized as a result of his first street fight. No one said being a hero was going to be easy…

Hit-Girl is just your ordinary, run-of-the-mill assassin who wields a sword and slices and dices drug kingpins for fun. She’s also 11 years old. But as Kick-Ass soon learns, Hit-Girl isn’t the only other costume-wearing weirdo running around out there.

Big Daddy is literally that — big, and a daddy. Specifically, he’s Hit-Girl’s father, who has made the some-might-say dubious decision to raise his little girl as a lethal killer, working continuously on a mission of revenge against the crime boss who killed his wife and his daughter’s mother. Far from a superhero himself, Big Daddy simply sees Kick-Ass as a way of furthering his own murderous plans.

Official Plot Synopsis: A twisted, funny, high-octane adventure, director Matthew Vaughn brings KICK-ASS to the big screen. KICK-ASS tells the story of average teenager Dave Lizewski (Aaron Johnson), a comic-book fanboy who decides to take his obsession as inspiration to become a real-life superhero. As any good superhero would, he chooses a new name — Kick-Ass — assembles a suit and mask to wear, and gets to work fighting crime. There¹s only one problem standing in his way: Kick-Ass has absolutely no superpowers. His life is forever changed as he inspires a subculture of copy cats, is hunted by assorted violent and unpleasant characters, and meets up with a pair of crazed vigilantes, including an 11-year-old sword-wielding dynamo, Hit Girl (Chloë Moretz) and her father, Big Daddy (Nicolas Cage).

Kick-Ass will hit theaters on April 16th 2009.
