#3. John Cena
John Cena's appearances have been decreasing by the year and his potential utilization at WrestleMania 36 is questionable. He's another legend who has shown nothing but generosity these past 4-5 years, putting over top talent on multiple occasions.
AJ Styles, Dean Ambrose, Seth Rollins, Roman Reigns, Shinsuke Nakamura, and Finn Balor are some of the names he's helped in a big way during and after his transition into a part-time Superstar.
Charlotte Flair to return and wrestle a CURRENT CHAMPION?
Having been on the top of the mountain longer than anyone in modern WWE history, he knows the value of giving back and he did that with Bray Wyatt in 2017 at the Elimination Chamber and two nights after, telling Wyatt "you're a real champ now" as he took the pinfall.
He beat Wyatt at WrestleMania 30 in a match that he shouldn't have, but he can still have a great feud with The Fiend - with the storyline taking a new form as compared to their rivalry 6 years ago.
Utilizing Cena against Bray Wyatt would be the best thing WWE could do and there's little doubt that Cena would put him over.
