#2. Bobby Roode
Second on the list is none other than the Glorious one himself.
Bobby Roode has appeared on Raw & Smackdown, and despite having success in winning championships- his character has been very stale. Roode first arrived on Smackdown, where he managed to gain the US Championship. He was also embroiled in feuds with superstars such as Randy Orton, Rusev & Jinder Mahal- but he was never treated like the big deal that he should've been.
NXT was the platform where Roode thrived, and we saw The Glorious One at his best as he had an NXT Championship reign which lasted for a very long time. Roode played the role of a perfect heel who was not only glorious on the mic, but he was very calculated and tough in the ring as he was able to put on great matches with everybody.
But now, Roode is on Monday Night Raw- and he is one half of the Raw Tag Team Champion alongside Chad Gable. Their tag team has not been very entertaining as you would expect due to the booking. The best way for Roode to find himself again would be to have him & Gable lose the tag team titles, only for Roode to turn on Gable with a vicious attack.
Roode can simply state to the world that he doesn't need the fans anymore. The Glorious character is somebody who should be egotistical, conniving and simply reckless. This is the example of who Roode was during his run on NXT, where he didn't care about who he offended or attacked.
At the age of 41, Roode may not ever be in contention to be the face of the company- but he would definitely work as a heel talent that could easily slide in and out of the main event scene when needed.
