4. Goldberg

Another former football player turned wrestler, Goldberg was one of the most popular wrestlers during his stint with WCW, likely due to a long undefeated streak that spanned more than 450 days and involved nearly 200 events. During his streak, he beat other famed figures like Raven, Curt Hennig, “Hollywood” Hogan and most of The nWo.

Following the folding of WCW, he went overseas with the All Japan Pro Wrestling. Later, he returned to the states and made his debut with the WWE.
