Its gotta be Kane!!
At the 1990 Survivor Series PPV in Hartford, CT a man who has become one of the more recognizable and legendary WWE superstars of all-time Mark Calaway made his debut as the character "The Undertaker". Fast forwarding 28-years later and "The Deadman" still competes for WWE sporadically to bring today's current crop of stars to the dark side. The man who was alongside The Undertaker for his debut was former WWE creative writer Bruce Prichard or better known by some as "Brother Love".
Besides The Undertaker's numerous championships victories and his ominous presence, an individual who was always linked to Taker is a man who is currently running for Mayor of Knox County, TN, former WWF Champion Kane. Kane recently competed at WWE's 'Extreme Rules' PPV on July 15th where he and Daniel Bryan attempted to win the SmackDown Live Tag Team Titles.
While making a guest appearance on Busted Open Radio with Dave LaGreca and WWE Hall Of Famer Mark Henry, Bruce Prichard was asked about some of the characters and creations that he had his hands on during his time in the WWE/F and he stated that having a hand in bringing the characters of The Undertaker and Kane to life were two of his personal favorites.
“The Undertaker. Creating The Undertaker and Kane." Prichard said. "That, first of all just seeing I was a fan of Mean Mark Callous when he first started in Dallas and I watched him through his time in WCW--I always liked him… I didn’t know him personally but I liked him--the way he worked, he was unique and I created that character, not necessarily The Undertaker but he was the black to Brother Love’s white and he was the yin to my yang and, then, Vince came up with the name The Undertaker but being able to build that character and having the human being behind that character that really made it work. It wasn’t me, it was the guy behind the character that made it work, and then the story of Kane and his brother that was in the fire and the whole nine yards. That story and those two characters are probably, immediately what I point to and go, ‘Yeah that’s it’.”
Bruce Prichard also stated during this interview that sometimes the host of his 'Something To Wrestle' podcast Conrad Thompson can get under his skin. For more on that, head over to Fightful's article published about it.
