#4 Bobby Lashley

Bobby Lashley's return to the WWE is finally picking up some steam following his Intercontinental championship win when he defeated Seth Rollins and Dean Ambrose in a triple threat match.
Lashley, who is a heel now after debuting in 2018 as a face, has got some heat on him, thanks mainly to his annoying sidekick, Lio Rush. But the Intercontinental champion hasn't had a memorable feud yet, but one involving Vince McMahon could be in the works.
Lashley and Vince McMahon have history, with the two involved in a feud, where Lashley represented Donald Trump in a hair vs hair match against Vince McMahon's representative, Umaga. Lashley won and Vince's hair was shaved following the match by Lashley, Trump, and Stone Cold Steve Austin.
Lashley then went on to feud with Vince McMahon for the ECW World Championship, which he won. WWE could maybe revisit this storyline and bring it back in 2019, with Lashley attacking the boss for screwing him over.
