#3 The O.C. take out the Big Red Machine to make things more personal
With Vince McMahon and Paul Heyman being the purveyor of tone in this case, the O.C ganging up on a returning Kane could elevate the stature of this feud heading into WrestleMania 36.
The Big Red Machine is undoubtedly one of the biggest names in professional wrestling and his relationship with The Undertaker could help intensify this feud even more.

Judging by the way AJ Styles ripped through The Undertaker's life in his promo, it could trigger the demonic Kane into returning to the squared circle to confront the O.C.
Whilst I'm intrigued to see the Undertaker and AJ Styles collide in a singles bout, having Kane alongside The Phenom heading into Tampa, won't be much of a problem.
An idealistic approach involves AJ Styles and his cohorts doing whatever it takes to make this feud a more personal affair. Attacking a returning Kane not only heat things, but it also allows the audience to see a more vengeful Undertaker vowing to take The Phenomenal One's soul at WrestleMania.
