#3. Rick Rude
The late "Ravishing" Rick Rude has many accolades milestones in his Hall of Fame career. But, aside from multiple titles, legendary feuds and one of the greatest personas in wrestling history, there's one fascinating historical tidbit he can lay claim to. He's the first and, as far as I know of, only performer to appear on WWE Monday Night Raw and WCW Monday Nitro on the same night.
The episodes aired on November 17, 1997. During that particular era in the company's history, the WWF would tape episodes of Raw every other week as a cost-cutting measure. Rude appeared on the live episode of Nitro, ripping on both his former company as well as his former faction, Degeneration-X. An hour later, Rude showed up on the pre-taped Raw... along with DX.
Interestingly enough, he was also featured on an episode of ECW TV that aired in syndication that week - making him to only performer to have that accomplishment, as well.
While this was certainly a memorable moment in the history of the Monday Night Wars, Rude merely filled a managerial role in the faction, and only to back up his fellow Minnesota native, Curt Hennig. He was only in the company for less than two years, leaving in 1999 in order to train for a return to active in-ring performing.
Unfortunately, Rude would pass away that year from heart failure. He was 40 years old. He was, rightfully, inducted into the WWE Hall of Fame 18 years later.
