There was a superheavyweight thread recently where Viscera was brought up a few times. Has there been a wrestler with a wider scope of "in character" personality changes than him? He was a rapper, a King, a monster, and a love machine all without having a
true clean slate.
Someone like Ziggler wouldn't count since I don't think the current character was ever supposed to have been a cheerleader or a caddy.
I think that Brutus Beefcake's various identities in WCW were all supposed to be the same person, so I'd vote for him if so.
