The Undertaker is one of the most well-known superstars throughout WWE history. He's not only popular amongst WWE fans, but within the mainstream media as well.
The Phenom rose to prominence alongside the likes of Stone Cold Steve Austin and The Rock during the Attitude Era. His popularity grew further thanks to The Streak, a series of 21 straight victories at WrestleMania.
What many non-hardcore WWE fans don't know though is that Mark Calaway actually wrestled for WCW before joining WWE and becoming one of their biggest stars in history.
Calaway wasn't a big name in WCW. He had a completely different gimmick to how we see him in the ring nowadays, performing under the name Mean Mark Callous.
It was another wrestling legend that was responsible for bringing The Deadman to WWE. Sgt. Slaughter saw a video of him and brought him to the company.

During a recent interview with Sports Illustrated prior to WrestleMania 35, the WWE Hall of Famer recalled how he helped bring The Undertaker to the WWE.
Slaughter said, via Fightful: “To not lose a WrestleMania for 21 years is pretty astounding. Then I brought him into the WWE always made me feel even better. Yeah, helped bring him in.
"He was wrestling down in WCW, kinda floundering around. [He] had real short hair red hair. Mark Callous, Mean Mark Callous.
"[I] saw a video of him, took it to Vince McMahon and he said, ‘Serge, if you think he’s good enough to be here, bring him in for a tryout’ so, brought him into Rochester, New York.
"He wrestled the first match and as I was watching the match, all of a sudden, my headset went off my ear and I heard Vince McMahon’s voice and he said, ‘Where’d you find this guy?’ And I said, ‘In a box of tapes’.
"He said, ‘Well, send him to my office when he’s done’ so, Mark came back from the ring and he said, ‘How did I do?’ I said, ‘Vince McMahon wants to talk to you’.
"He said, ‘Oh, did I do something wrong?’ I said, ‘I think you probably did something right’ so I introduced him to Vince and he’s been there ever since.”
The rest, as they say, is history.
The Undertaker is still wrestling with the WWE today, and he recently signed a new deal with the company, according to Dave Meltzer of Wrestling Observer Radio, via Ringside News.
His next match for the WWE will likely be in Saudi Arabia in June, where he is expected to face Elias following their confrontation on Monday Night Raw last week after WrestleMania 35.
