When he made his return in 2000, he abandoned the somber mortician-themed attires, his funeral dirge ring music, allusions to the supernatural and the accompanying morbid theatrics. In place of this, he took on a biker identity, riding to the ring on a motorcycle and wearing sunglasses and bandanas to the ring. His entrance music was replaced with popular rock songs of the time, like Limp Bizkit's "Rollin' (Air Raid Vehicle)" and Kid Rock's "American Bad Ass" (from which the name of The Undertaker's new gimmick originated), though it was accompanied by the characteristic opening bell of The Undertaker's original theme. According to Bruce Prichard, Callaway asked for the change since he wanted to be "the biker, he wanted to be the guy that he is in everyday life".
