#2: Mark Henry
Mark Henry has always been an anomaly in WWE.
Joining with one of the company's most lucrative contracts ever, Henry for years wallowed in the mid-card, before leaving TV in early 2004.
Returning in 2006, Henry would again be part of the mid-card, as very few saw any potential in the future Hall of Famer. That all changed in 2011 though, as the World's Strongest Man was drafted to SmackDown, and attacked fellow blue Superstars Christian and John Cena.
A new heel, Henry showed off his mean-streak with the incredible Hall of Pain, as he would punish stars of all sizes.
This path of destruction set Henry on a collision course with Randy Orton, and at Night of Champions, Henry destroyed the Viper, proving his worth and taking the World Heavyweight Championship in the process.
