#4 Goldberg (The Rock)
Goldberg was certainly more than a rising star when he made his WWE debut. One of WCW's biggest attractions and the former holder of one of the most impressive undefeated streaks in history, he came to the company as a major star.
Goldberg debuted in a memorable segment boosted by the outrageous facial expressions of The Rock. He went on to defeat the People's Champion at Backlash, devastating his opponent with multiple spears and a Jackhammer.
Goldberg's first WWE run did not go as expected, but he more than made up for it in his unlikely second run, winning multiple world championships.
#3 Former WWE Tag Team Champion Tazz (Kurt Angle)
Tazz was initially presented by the company as a big deal. The Human Suplex Machine defeated Kurt Angle in his debut to end the latter's undefeated streak.
Tazz wasn't booked to perfection during his WWE career. Even more troubling was his history of injuries, which led him to an early retirement. He remained in the company as a color commentator for years before joining TNA. The two-time ECW World Heavyweight Champion currently works in AEW as a commentator and manager.
