#5. John Cena

John Cena is a Superstar who has long surpassed his 'polarizing' status that dominated most of his career. His transition into a part-timer isn't one like The Undertaker or Goldberg where fans think that they need to take a step back.
If anything, John Cena's decreased presence on WWE television has made fans fonder of him. Every time he returns to the squared circle, we're reminded of why he's truly among the all-time greats - something that fans never realized until he took a step back.

While his time on the top seems to be all but over, there's never a dull moment when he's around. Win or lose, he'll always have a prominent spot on television and returning to face 'The Fiend' Bray Wyatt at WrestleMania 36 is one such example of that.
From what the rumors suggested, WWE considered the possibility of John Cena vs Goldberg. We can't imagine that they won't try making that match at some point and Cena would be the perfect big-match opponent to end Goldberg's career.
