#4. Former two-time WWE World Champion Christian
Despite the last few years of Christian's WWE career being plagued by injuries, the former WWE World Champion was a surprise entrant in the 2021 Men's Royal Rumble match.
Christian was able to embrace his long-time friend Edge and bask in a moment that many WWE fans didn't believe he would ever be part of. One of the main reasons why Christian made his in-ring return is because of his recent body transformation.

Nutrition Solutions commented on Christian's body transformation through their Instagram account:
"Being a pro athlete his entire life who is well known for his work ethic and competitiveness, Jay committed not just to getting himself back in shape, but getting himself in the best shape of his life at 47 years young! And as you can see, in just 5 months time he’s made some remarkable progress!"
The former WWE star is now 47-years-old but showed that his commitment in the five months leading up to his in-ring return definitely paid off. Christian's return was a hit. There are now rumors that the former star could return on a part-time basis in the future.
