4. Kevin Nash
WWE.comA slightly dubious inclusion on the list, given the fact that Nash's most drastic image change was undertaken by the WWF, but one which remains relevant given the sheer awfulness of his early appearance. 'Big Sexy' spent much of 1991 as the laughable Oz, a character based on the titular figure of the famous book (and film). Oz was, without a doubt, one of the most strange, outdated gimmicks in wrestling. Nash would walk to the ring in a billowing green cape and, most bizarrely, a wizard's mask and hat. He'd thankfully remove these before wrestling, but still retained a ridiculous air. WCW thankfully kept Nash's look simple upon his return, allowing him to dress in street-style clothing which would form the foundation of the nWo's iconic image.
