Undertaker

The moment his signature gong echoes though the darkness, The Undertaker captivates the WWE Universe by his mere presence. The Deadman from Death Valley is usually a man of few words, but he can intimidate even the toughest WWE Superstars with just one glance. His somber persona and seemingly mystical powers has been a terrifying trademark of WWE for more than two decades and no list of WWE all-time greats can be considered complete without him.

First seen at the 1990 Survivor Series, Undertaker was introduced as the final member of Ted DiBiase's "Million Dollar Team." Since then, he has become a multiple time WWE and World Heavyweight Champion and maintained a WrestleMania undefeated streak that currently stands at an incredible 19-0.

To cement his tremendous legacy in the squared circle, The Deadman has defeated such elite Superstars as Shawn Michaels, Triple H, "Stone Cold" Steve Austin, Randy Orton, Bret "Hit Man" Hart, The Rock and Edge.

Throughout his time in WWE, The Undertaker has notoriously disappeared for months at a time. Often thought dead and "resting in peace," The Phenom always mysteriously returns to the ring to seek vengeance against those who have sent him away. From Yokozuna to Kane to Edge, Undertaker always finds a way to claim the souls of those who have wronged him.

In addition to his solo success, The Deadman has been quite the team player throughout his career. From his lengthy relationship with manager Paul Bearer to spearheading The Ministry of Darkness, The Phenom has been successful in every venture. He has even captured tag team glory alongside the likes of The Rock, "Stone Cold" Steve Austin, Big Show and his own Brother of Destruction, Kane.

In fact, The Big Red Monster is the ally-turned-adversary (and often back again) that The Undertaker continuously comes to crosses with. Kane made his WWE debut by costing his half-brother the first-ever Hell in a Cell Match. While their relationship is always turbulent, together they are nearly unstoppable.

The Undertaker has many firsts to his credit. Aside from being the originator of the Tombstone, he has also taken part in the inaugural Hell in a Cell in October 1997, as well as the first-ever Casket Match Survivor Series 1992. Throughout it all, The Undertaker has remained one of WWE's most popular Superstars, virtually cementing his place as a future Hall of Famer
