#3 Vladimir Kozlov
When Vladimir Kozlov made his in-ring debut in 2008, the colossal star was a monster heel, demolishing everyone in his way.
Entering a feud with then-WWE Champion, Kozlov was impressive but failed to take the title.
After being knocked down the totem pole, the Moscow Mauler became part of a great comedy duo with Santino Marella, and succeeded in winning the Tag Team titles.
After losing the gold, Kozlov quietly retired from wrestling in 2011, to focus on other ventures.
These other ventures included completely transforming his body, as the former champion is almost unrecognisable to the WWE Universe.
Taking his incredible physique to Hollywood, Kozlov has appeared in hits including Fast and Furious 6 and John Wick 2, and attributed his physical change to needing to be flexible for stunt work.
