Possible Match(es): Undertaker vs. Randy Orton John Bradshaw Layfield vs. John Cena Batista vs. Triple H WrestleMania 21 is where the streak became 'The Streak'. Although many were aware of The Undertaker's undefeat streak at wrestleManias it didn't really become part of the deadman's gimmick until he went up against The Legend Killer Randy Orton. From this point onwards the WWE had a main angle sorted at WrestleMania guaranteed by the fact that The Undertaker would be wrestling. This WrestleMania was also the start of a new era where both John Cena and Dave Batista rose to become World Champions. Interestingly the WWE seemed to have more faith in Batista than Cena as Cena was only challenging JBL for the SmackDown World Title whilst Batista and Triple H were closing the show.
