#1 Bray Wyatt could have become a "God" after ending The Undertaker's Streak
The closest WWE has come recently at recreating an Undertaker-esque supernatural gimmick has been through Bray Wyatt. He, like the Deadman, thrives on darkness and uses mind games to play with his opponents. Wyatt should be the true successor to The Undertaker and he probably is, thanks to The Fiend.
However, before Wyatt created his monstrous alter-ego and the Firefly Fun House, WWE should have given him the opportunity of a lifetime. As one of the most intriguing characters in recent history, he should have gotten the keys to the kingdom.
Had The Undertaker left WrestleMania 30 at 22-0, the 'Eater of Worlds' should have been the one to put the Deadman down. Wyatt did face him at the following year's WrestleMania, putting 'Taker over in the most straightforward way imaginable. He, along with the rest of the Wyatt Family, lost to the Brothers of Destruction at that year's Survivor Series.
Things could have been so different if WWE waited a year or two to build Bray Wyatt and his "family" up to the point where he could pose a serious threat to The Undertaker at WrestleMania. A victory over the Deadman at 'Mania would have cemented him as the New Face of Fear and the "God" that he always claimed to be.
Had Wyatt ended The Streak, it would have been a "passing of the torch" moment from one supernatural being to another. He would have gone to the next level without ever needing The Fiend. That being said, Bray Wyatt could still stand tall over The Undertaker at WrestleMania if he interrupts the Deadman's 'Final Farewell' at Survivor Series.
