#2 WWE Hall of Famer Hulk Hogan (Hulk Hogan / Mr. America)
Even Hulk Hogan, one of the most marketable performers in the history of WWE, had to don a mask at one point in his career. In 2003, the villainous Mr. McMahon forced the former franchise to stay away from the ring and events. A mysteriously familiar masked superstar entered the scene shortly after.
Mr. America copied all mannerisms of The Hulkster, including his gestures, moves, and verbal style, although he was fierce in his rejection of the fact of him being Hulk Hogan in disguise. Meanwhile, Hogan left the company in real life, and McMahon fired the masked sensation in kayfabe. In his subsequent returns, Hogan has donned familiar colors.
#1 WWE Hall of Famer Mick Foley (Mankind / Cactus Jack / Dude Love)
Carrying the usage of multiple individualities to a different tier, Mrs. Foley's Baby Boy went on to use three personalities in WWE to some success. They comprised of the deranged and deserted Mankind, the hardcore legend Cactus Jack, and the relaxed hippie Dude Love.
In a glorious moment, the 1998 edition of WWE Royal Rumble saw all three personalities take part in the eponymous match, much to the enjoyment of the spectators and the confusion of the opponents. In WWE, Mankind remained the most prosperous gimmick, but all three linger beloved amongst fans today.
