Kick-Ass ending explained (spoilers)

[Aaronduthf]

Big Daddy is burnt to death.

Kick Ass shoots the mob boss with a bazooka, sending him clear across the sky only to explode into another building.

Kick Ass uses the jetpack with machine guns to rescue HitGirl where her name is revealed to be 'Mindy'.

Red Mist survives and takes over his father's business. Final line of the movie:

Red Mist: As a great man once said 'Wait til they get a load of me!' before putting on better, more elaborate mask.

[Damiano]

After promising his new girlfriend Katie that he will quit being Kick-Ass, Dave appears on TV to unmask himself. However, it turns out that DAmicos men have kidnapped Dave and Big Daddy, killed Hit Girl, and are broadcasting their brutal torturing of the two on live TV. They pour gasoline over them and are about to light them on fire when Hit Girl (who survived being shot by Red Mist) comes in and kills all the henchmen, but not before they burn Big Daddy alive. Kick-Ass and Hit Girl break into DAmicos building and slaughter everyone except DAmico and Red Mist. Kick-Ass fights and defeats Red Mist while DAmico fights Hit Girl. DAmico is about to kill Hit Girl, but then Kick-Ass shoots him with a bazooka (yes, a bazooka), blowing him out into the air from a high storey window. Kick-Ass and Hit Girl reveal their secret identities to each other. Hit Girl enrolls at Daves school. Dave quits being Kick-Ass, but what he doesnt know is that Red Mist has vowed revenge for his father...
