1. The Authority
Brock Lesnar is the most unstoppable force in WWE. The Authority rules with an iron first. The latter is bound to be involved in a Wrestlemania feud. Seth Rollins is the most likely candidate for that feud, but Brock Lesnar is another man that could be the one to eliminate The Authority.
It’s a fascinating story to tell of Lesnar trying to bring down the machine while the machine manipulates the attempts to crush its biggest asset that has gotten out of control. The seeds for this feud were already planted after Wrestlemania 31 when The Authority suspended Brock Lesnar.
If The Authority costs Lesnar his honor by forcing his loss to The Undertaker this Sunday, Lesnar would be on the warpath. As random as his appearances can be, The Authority could never predict an attack from The Beast Incarnate.
It would be a cold war between the two most powerful forces in WWE. In the two most powerful forces in WWE. The only concern is who would step in for The Authority at Wrestlemania 32. Honestly, anyone from this list would do well under the right circumstances.
