7. The Undertaker Kills Paul Bearer - Great American Bash 2004
In the Ruthless Aggression era of 2002, the WWE had moved away from the wacky gimmicks and went for more realistic characters. The Undertaker had even become more human, shedding his Deadman gimmick in favor of the more realistic American Badass biker. Still, a contingent that was longing for nostalgia had pushed for The Deadman (and all of the supernatural powers that came with it) to return, which happened at Wrestlemania XX. With the return of the Deadman came a return to wacky, supernatural gimmicks. Paul Heyman had kidnapped Paul Bearer, thus taking control of the Deadman. It would lead to a Live Free or Die match (later named a Concrete Crypt match because WWE rightly didnt want to advertise the fact that there could be death) where if Undertaker lost to the Dudleys, Paul Bearer would be buried in concrete. Taker won, but then decided to bury his former manager anyway, thus turning heel. http://www.youtube.com/watch?v=wMvLoCVY1ko As a heel, Taker would go on to defeat John Cena on an episode of Smackdown, but realizing that he had nobody else to feud with, the writing team quickly turned him back babyface and put him against WWE Champion JBL. All that ended up coming out of Takers heel turn was a concrete Paul Bearer. Taker would never again wrestle as a heel in his WWE career.
