Throughout WWE history, many superstars have undergone changes in characters. Whether it was a slight alteration or a complete makeover, it's common to see a wrestler go through two to three iterations before finding something that sticks.
Some examples in WWE today include Tensai (Albert, A-Train), Ryback (Skip Sheffield) and Damien Sandow (Idol Stevens).
Some wrestlers in the past made a career out of it (Brutus Beefcake, The Godfather, Crush and Rikishi might have been their most popular characters, but they have a long list of portrayals).
Umaga- Before he was the Samoan Bulldozer, he was Jamal, one-half of 3-Minute Warning. Jamal never screamed main event.
JBL- John Bradshaw Layfield.
Now, Bradshaw of the APA,Justin Hawk Bradshaw or Blackjack Bradshaw.
Dolph Ziggler- Spirit Squad and Dolph's days as Nicky—but even Dolph Ziggler started as a guy who just annoyed people by introducing himself constantly.
