Undertaker
One year. That's how long it took Undertaker to climb to the very top of the WWE. He hasn't looked back since.
He made his surprise debut at the 1990 Survivor Series, where Undertaker began a decade-and-a-half of destruction with a bang. He defeated two Superstars before he was counted out of the eight-man tag team elimination match. The following year, at Survivor Series, he defeated Hulk Hogan to capture his first WWE Championship. Although he lost the title just days later at Tuesday in Texas, fans soon learned that Undertaker wasn't going anywhere any time soon.
Six years later, "the Man from the Dark Side" ousted Sycho Sid for his second title.
Two years after that, he took out Stone Cold Steve Austin for is third championship. In 2002, in a rematch of his Survivor Series 1991 showdown, Undertaker defeated Hogan once again to earn his fourth WWE Championship reign.
Whether it's been against monsters such as Giant Gonzales, Yokozuna, and Kamala, or icons like triple H, Hogan, Flair and Austin, Undertaker has battled and defeated every challenger that's come his way. With each victory, he just grew stronger.
At 6-foot-10, 328 pounds, one might think that the "Deadman's" biggest asset would be his size. However, as evidenced throughout his career, intimidation may be Undertaker's greatest weapon. From the eerie way he walks to the ring, to the imposing way he sits up from some of the most devastating maneuvers ever used, Undertaker has a reputation of being fearless. He's fought in Casket Matches, Buried Alive Matches, Hell in a Cell Matches, and even Inferno Matches, where the object of the contest is to set your opponent on fire, and he's never even flinched.
Using a variety of high-impact maneuvers, such as the Tombstone, the Chokeslam, and the Last Ride, Undertaker has left a legacy of carnage that will surely lead to his eventual inclusion in the WWE Hall of Fame.
Fresh on the heels of an amazing victory over "Legend Killer" Randy Orton at WrestleMania 21 that brought his WrestleMania record to 13-0, there's a very good chance we haven't seen Undertaker's last Championship reign yet.
