The battle theme from Panty and Stocking with Gaterbelt....the music that plays after the transformation scenes, if you've seen the series, think back to that epic battle between the Anarchy Sisters and the Succubus Sisters in the school, the music that plays when the 6 of them are ripping the school apart just to kill each other (i'm also including Chuck and the Succubus Sister's pet since those 2 fight with Cars)
