Much like Andre the Giant and The Big Show (who doesn't make an appearance on this list), Mark Henry is somebody who can pretty much do whatever he likes to whoever he likes. Despite debuting way back in 1996, it wasn't really until the late 2011 that Henry started to really become a main event player. He'd been Sexual Chocolate, he'd been a member of The Nation of Domination, he'd even been ECW World Champion, but Henry only really started to realise his potential after being drafted to the Smackdown brand in 2011. The World's Strongest Man was a moniker often used by Henry, but it was only at this point that he started to look truly dominant, even defeating Randy Orton clean to become the World Heavyweight Champion. This was a brutal, seemingly always pissed off Henry who was only too happy to induct many a competitor into the Hall of Pain as he proclaimed "that's what I do." To the surprise of many, Mark Henry has gone on to be portrayed as a true badass during his most recent years in the WWE, although the powerhouse does seem have his injury issues. That said, it looks like he'll be on the card in some form come Wrestlemania this year.
