When a certain God of Thunder had his toenails clipped, one of them rode on the lightning storm that was happening underneath. That toenail(together with the lightning) ended up hitting one of the "pro-wrestlers" during a match.
Because of it's special abilities it made the wrestler into a giant toenail with a lightning crack in the middle. This toenail now roams the World fearing it may be hit by lightning once more if found and set on an antenna 15 ft. high, during a storm.
If you find a Thundertaker, you must make it your pet! It has powers to control monster toenails!
