3. Steve Blackman
WWE.comSteve Blackman became a regular performer in WWE after his debut on the November 3, 1997 edition of Raw. It wasn't a traditional debut, though. It was very unique in that he went into the ring, nobody stopped him and he was able to unleash offensive moves on wrestlers. Vader was a babyface that was getting attacked by Jim Neidhart, Doug Furnas and Phil Lafon when this guy entered the ring. He unleashed martial arts kicks on the three men attacking Vader, but then he got overwhelmed by them due to the numbers game. https://www.youtube.com/watch?v=X_gXrIv9ID0 The announcers kept asking "who is this guy?" repeatedly as Jim Ross referred to him only as a fan. Blackman was protected by Vader, but then Blackman got taken away by security and was escorted out of the arena. Of course Blackman was a signed performer that was a trained wrestler from many years earlier. He was actually a part of Vader's team at Survivor Series six days after this too.
