#2 The Sultan (WWE Hall Of Famer Rikishi)
Rikishi entertained WWE of the late '90s and early '00s through his dancing spirit, happy-go-lucky persona, the stinkface, and his association with Too Cool. However, he played a variety of gimmicks before settling on the sumo-inspired ring name. Amongst others, he played a Samoan savage and a role model trying to make a difference.
Nevertheless, the most peculiar of Rikishi's many gimmicks is The Sultan. Managed by The Iron Sheik and Bob Backlund, The Sultan was a masked wrestler who never uttered a word. The reason behind his silence? His tongue was cut off. When The Sultan vanished and Rikishi arrived, he spoke and his tongue was visible for all to see.
#1 The Leviathan (WWE Hall Of Famer Batista)
Batista's Deacon gimmick is mentioned in the introduction of this list, but he has an ever weirder gimmick in store. In OVW, Batista was The Leviathan, a devilish figure created by Jim Cornette, who wanted it to be a foil for the likes of Kane and The Undertaker.
Batista's short-lived union with D-Von led to him turning on him. He joined Evolution and became one of the major WWE superstars of the 21st century, before leaving to fulfill Hollywood dreams. For The Leviathan, this would've been next to impossible to achieve.
