10 WrestleMania 34 Nightmares That Could Come True

2. Kane's Involvement Means There's No Biker Gimmick Reprise

Nightmare: Although the long-running saga between The Undertaker and Kane hardly makes sense at the best of times, it is notable that Kane showed up to defend his brother's honour on Raw and confront a bullish John Cena.

Does his presence hint that "The Deadman" character The Undertaker has played since 2004 will come out of retirement at WrestleMania to face Cena? In other words, will fans hoping to see 'Taker return as the "American Bad Ass" be robbed of that gimmick's reprise more than a decade after it was benched?

Perhaps that's why WWE wheeled out Kane on Raw. Maybe, just maybe, he was there to put any biker hopes to bed.

Chances Of It Coming True: It's possible, but there are some other things hinting that 'Taker will drive out on a motorcycle in New Orleans and become "Big Evil" once more.

Firstly, a large chunk of old-school fans want to see it. Secondly, it'd make sense given that The Undertaker left his trademark trench coat and hat mid-ring after losing to Roman Reigns at 'Mania 33. Lastly, Kid Rock is being inducted into the WWE Hall Of Fame shortly before this year's WrestleMania.

Could this be a coincidence? Perhaps, and yet it sounds reasonable to predict that Kid will perform a PG version of his American Bad Ass theme live, signalling the return of a re-energised biker 'Taker for his match against Cena.
