In October 1990, Calaway signed with the World Wrestling Federation (WWF). He made his debut as Kane the Undertaker at a taping of "Superstars" on November 19, 1990. Calaway made his official on-camera debut on November 22 at Survivor Series as a heel when he was the mystery partner of Ted DiBiase's Million Dollar Team. Approximately one minute into the match, The Undertaker eliminated Koko B. Ware with his finisher, the "Tombstone Piledriver". He also eliminated Dusty Rhodes before being counted out; however, his team won the match with DiBiase being the sole survivor. During the match, Calaway was referred to as The Undertaker, omitting the name 'Kane', which was dropped shortly after the event (and seven years later was given to another wrestler who eventually became Undertaker's younger brother of the same name). Throughout the end of 1990, The Undertaker mostly picked up squash victories against jobbers on Superstars of Wrestling and Wrestling Challenge tapings. He was a participant in the 1991 Royal Rumble match which was won by Hulk Hogan. In February 1991, The Undertaker switched managers from Brother Love to Paul Bearer – a histrionic, ghostly character, almost always seen bearing an urn, which he used to revive The Undertaker's strength whenever Undertaker fell victim to his opponents. Undertaker placed his defeated opponents (almost always jobbers) in a body bag and carried them to the back. He continued picking up victories in squash matches leading up to his first feud in the WWF with "Superfly" Jimmy Snuka.
