3 Current AEW stars and 2 WWE stars who won championships in WCW

#2. Former WWE Champion Rey Mysterio

With his colorful luchador masks, Rey Mysterio is one of the most marketable faces in WWE. WCW, however, decided to have him shed the mask.

Despite the dubious booking decision to have Rey Mysterio wrestle unmasked, The Ultimate Underdog enjoyed a successful run in WCW, especially in the pioneering Cruiserweight Division.

He won the WCW Cruiserweight Championship five times. He also managed to win a Cruiserweight Tag Team title and three world tag team titles in the promotion.

#2. AEW star and former WWE Champion Paul Wight

Paul Wight initially found success in WCW, where he was billed as the kayfabe son of Andre The Giant. He was an important part of the storyline involving The nWo and won the World Heavyweight Championship twice. The Giant also won three tag titles.

Paul Wight shifted base to WWE and achieved major success as The Big Show. He was considered a company loyalist, and his AEW signing was a surprise. He has since settled into a role as a commentator, although he steps inside the ring from time to time.
