#5. Gillberg (Duane Gill.)
During the Attitude Era, WWE programming began to feature some stars of ECW. Among those chosen to appear on Raw and Smack Down was a crew known as the J.O.B. Squad, which included Duane Gill.
Gill was considered a perennial underdog due to his short stature. However, he would wind up winning the WWE Light Heavyweight title from Christian.
What followed is what most people remember, however. Duane Gill was repackaged as Gillberg, a mockery of WCW's biggest star at the time, Bill Goldberg. Gillberg adopted all of Goldberg's mannerisms, albeit with a comedic twist.
Instead of a winning streak, Gilberg embarked on a losing streak. WWE has resurrected the gimmick from time to time since, but once Goldberg was under WWE contract Gillberg became obsolete.
Duane Gill was a decent in-ring worker, but his small size and lack of high flying ability pretty much guaranteed he would remain an enhancement talent until the end of his career.
FUN FACT: He also teamed up with fellow Enhancement Talent, Barry Hardy, to comprise the Teenage Mutant Ninja Turtles-"inspired" tag tea, the Toxic Turtles.
