#4 Turn face - Batista

There's no denying that Batista deserves to be recognized as one of the greatest WWE superstars to ever grace the squared circle.
His current tussle with Triple H will see the light of the day this Sunday in a No Holds Barred Match where The Game will be putting his in-ring career on the line.
Look who just shut down all of Tony Khan's critics! More HERE.
I have to admit this that Triple H's career-ending stipulation does bring an intriguing feel to this marquee feud here, but considering that this could very well be Batista's farewell encounter, it seems unlikely that The Animal will be walking out with the victory in this one.
He has stated multiple times that he wants his career to end on his terms and judging by the way WWE has booked this, The Game could very well be ending Batista's career this Sunday.
Now, getting back to why I believe this will result in the former World Champion turning face. Careers that end at WrestleMania tend to have an emotional conclusion and with these two heavyweights having so much history, this would be the right time for The Animal to turn babyface and close the curtain on an incredible career.
#5 Turn heel - Seth Rollins

If this week's Monday Night Raw segment between the Universal Champion Brock Lesnar and Seth Rollins was anything to take into consideration, then it feels that The Architect could be pulling off some dirty tactics from his book to get the job done.
With the Saudi Arabian show also set to happen in May, it's unlikely that The Beast Incarnate will be dropping the gold at The Grandest Stage of Them All.
Since the WWE Universe has been rooting for Rollins to be their savior and burn the Suplex City to the ground, losing here would certainly derail The Architect's momentum heading into the later stages of 2019.
It's understandable that the company does see Roman Reigns as the top guy on the red brand, Rollins using his dirty tricks to get the job done whilst reminiscing the days of WrestleMania 31 could bring some edge to this averagely booked feud.
