#4 The Undertaker
The Undertaker also made a return recently at Super ShowDown, where he rescued Rey Mysterio, who was getting a beatdown from The OC backstage. AJ Styles was set to win the Gauntlet match at the PPV, before The Undertaker arrived at the ring and won the match.
This feud between The Undertaker and Styles has resulted in a match between the two at WrestleMania 36, which will be officially confirmed soon. Styles is currently feuding with Aleister Black, whom he defeated this past week on RAW, where he also sent out a subtle message to The Phenom, copying The Undertaker's mannerisms.
Styles and Black are set to face off once again at Elimination Chamber in a no disqualification match. It's quite clear that The OC duo of Karl Anderson and Luke Gallows will take advantage of the no disqualification rules and interfere.
And we could see The Undertaker arrive to help Black and even the numbers. It would be quite a sight to see The Undertaker and Aleister Black in the same ring as well, as they are two Superstars with somewhat similar gimmicks.
