When Frank finds out that all his coke has been taken by Big Daddy (Which he doesn't know at first and thinks Kick-Ass is responsible) he orders Kick-Ass to be killed and murders a man dressed as Kick-Ass (who he mistook for the real Kick-Ass).
So Chris has a plan on how to get Kick-Ass, Chris disguises himself as a superhero called Red Mist and tricks Kick-Ass into becoming his friend, he drives him to his father's warehouse only to find out that his has been burned and all the men have been killed.
Frank thinks first that it is Kick-Ass' doing, but Chris shows him a surveillance tape of Big Daddy killing all the men and burning the building, Frank still doesn't change his mind about Kick-Ass and has both him and Big Daddy captured and he then lets his men post a live video of them beating up and torturing Big Daddy and Kick-Ass, just as they are about to set the place on fire and kill them both, Hit-Girl comes and kills all the men and rescues Kick-Ass but Big Daddy gets badly burned and dies, so Hit-Girl and Kick-Ass decide to break into D'Amico's place and they kill all the men and finally come face-to-face with D'Amico. Kick-Ass battles Red Mist while Hit-Girl and D'Amico engage in a brutal fight, which D'Amico wins. Just as he is about to kill Hit-Girl, Kick-Ass appears with Big Daddy's bazooka and blasts D'Amico through a window, killing him in an explosion high above the city. Chris is shown at the end of the film, swearing vengeance on both Kick-Ass and Hit-Girl for his father's death.
