#1 A modern-day Two Man Power Trip (positive)
Brock Lesnar has been out of action for the past 5 months, but it's a guarantee that The Beast is going to come back at some point in time. What happens when Lesnar returns? Now that Roman Reigns is aligned with Paul Heyman, there's a string of interesting possibilities ahead of us. When Lesnar returns, two things could possibly happen. Enraged at seeing Heyman with Roman Reigns, he kicks off a feud with The Big Dog. The thing is, we have seen these two behemoths fight too many times in the past (with the duo headlining WrestleMania on two different occasions), and that's the reason why it seems highly unlikely that WWE will bring back this rivalry again.
The other possibility is that we will witness a modern incarnation of the Two Man Power Trip. Back in 2001, Stone Cold Steve Austin turned heel at WrestleMania 17 and later formed an alliance with Triple H, thus creating the Two Man Power Trip. The run didn't last long courtesy Triple H's injury, that took him out for months.

WWE has the opportunity to recreate this angle with two of the biggest Superstars in the company right now. Heyman could be the glue that holds these two men together, leading to a short stint that could see Lesnar and Roman Reigns wreaking havoc on the WWE roster. WWE could even throw in a short-lived Tag Team title reign for good measure, just like they did with Austin and Triple H.
There are tons of possibilities when Lesnar returns, but this is the one that many fans and wrestling experts are hoping to see unfold in the near future. Only time will tell how WWE handles Roman Reigns as a heel, but the WWE Universe is excited about it and is ready for some intriguing programming in the coming months.
