What is shown of Big Daddys' past is restricted to the last 10 years. He was once a cop, with his friend Marcus, but was framed as a drug dealer by Frank D'Amico. Big Daddy spent 5 years in jail, missing the first 5 years of his daughters life. His time in jail consisted of him planning and scheming about how to get revenge on Frank D'Amico. Once freed from jail, and re-united with his daughter (later known as Hit-Girl), he set to work executing his plan. He then proceeded to spend the next 5 years training his young daughter about weaponry, fighting styles and how to take a bullet to the chest.
Later, son of crime boss Frank D'Amico, Red Mist learns that Big Daddy and Hit-Girl, not Kick-Ass, are the vigilantes intent on bringing down his father's business. He fools Kick-Ass into taking him to meet the two, in order to lure all three heroes into a trap.
Frank thinks first that it is 'Kick-Ass' doing, but Chris shows him a surveilance tape of Big Daddy killing all the men and burning the building, Frank doesn't agree about Kick-Ass and has both him and Big Daddy captured and he then lets his men post a live video of 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.
Behind the scenes
- In the comics, Big Daddy wears a butcher's uniform, but as a joke, the filmmakers chose him to wear a costume parodying the DC Comics superhero Batman in the movie adaptation.
