6. King Kong Bundy
Other than competing in the main event of the second hour at Wrestlemania II, almost nothing can be said about King Kong Bundy's influence in the WWE. Between his debut year of 1985 until the year in which he had his final match in 1995, just over 6 years were spent on hiatus. Billed at 450+ Lbs, the appeal of King Kong Bundy was his massive stature, a label passed down to Mabel in the 1995 Royal Rumble after being eliminated by him in 3 minutes despite being a favourite to win that year. By that point King Kong Bundy had been in the professional wrestling industry for a total of 8 out of 14 years and could really offer little except being a behemoth. If King Kong Bundy were to find himself bested by a younger, more agile competitor for the sake of simulation, he could always rely on managers such as Bobby Heenan or Ted DiBiase to make sure he comes out on top. However this tactic can only work so many times, and with his offence being primarily slams the modern day wrestler could have a variety of ways to wear down such a beast.
