#4 Kevin Owens - Monday Night Raw
Kevin Owens was poised to have a big return to SmackDown Live and face Daniel Bryan at WrestleMania 35, but Kofi Kingston would get the spot instead.
The Prizefighter has faced a lot of superstars on both brands, but would probably benefit Monday Night Raw the most.
As a former Universal Champion, Owens could immediately jump into the world title picture and face his old rival, Seth Rollins.
This feud was clouded with interference from Chris Jericho in 2016, but revisiting the feud with Owens as the challenger would make for great TV.
In addition to Rollins, Owens could always revisit his feud with Roman Reigns or Bobby Lashely, the superstar who defeated him before he left to deal with his injuries.
Yet, the biggest and most interesting opportunity would be for Owens to reignite his feud with fellow ROH, PWG and NXT alum Sami Zayn.
