#5. Big Show
Big Show is also one of the longest-tenured Superstars in WWE. He has been a loyal servant to the company since 1999 (minus a brief departure in 2006-07) and has done whatever the company has asked him to do.
Big Show has admitted that he could have been booked better, but that hasn't stopped him from putting over whoever WWE asked him to. His most recent stint saw him put over Randy Orton in the latter's resurgent 2020 run.
Given how in-and-out he is with WWE these days, it wouldn't be surprising to see Big Show abruptly stop wrestling without anyone realizing it.
#4. The Rock - A quiet retirement from WWE?
The Rock is a Superstar who quietly retired from WWE years ago. His last match was against John Cena in the main event of WrestleMania 29. While his last match "technically" was against Erick Rowan at WrestleMania 32, it was a bout that lasted all of six seconds.
While a main event match against John Cena would be the perfect retirement match for The Rock, it was never meant to be. The Rock had once revealed at the end of 2013 that the original plan for WrestleMania 30 was for him to face Brock Lesnar.
Triple H had also revealed that the original plan for the WrestleMania 32 main event was a match between himself and The Rock. The Great One never got an official farewell match, and given his status in Hollywood and outside pressure, the chances of him ever returning to the ring again are slim.
