30. Mantaur
Mantaur is definitely one of the most bizarre WWE wrestlers of all time. The character consisted of a very creepy-looking bull mask, resembling the Minotaur from Greek mythology. He would also act like one, going on rampages, charging, trampling, and even mooing at opponents. After wrestling as Mantaur for several years, Mike Halac decided to change personas and leave the bull mask behind, revealing his face to the world. He still wore paint to cover his face, but his new persona was completely different. After being the Tank for a few years, he retired in 2005.
