Kane then formed a tag team with Rob Van Dam, with the duo eventually winning the World Tag Team Championship from Chief Morley and Lance Storm in a triple threat elimination match (also involving The Dudley Boyz) on the March 31 episode of "Raw". After they lost their World Tag Team Championship to La Résistance at Bad Blood, Triple H offered Kane a spot in his stable Evolution. Raw co-general manager Stone Cold Steve Austin offered Kane the opportunity to face Triple H for the World Heavyweight Championship if he rejected Triple H's offer; however, co-general manager Eric Bischoff insisted that if Kane lost the match, he would unmask. Kane accepted Austin's offer and challenged Triple H the following week in Madison Square Garden. Triple H won the match following interference from his stablemates, and on the June 23, 2003, episode of "Raw", Kane removed his mask. The unmasking rendered Kane emotionally unstable, and in an interview with Jim Ross, Kane attacked Ross and set him on fire. He later attacked Linda McMahon on the Raw stage. This action sparked a feud between Kane and Shane McMahon, Linda's son, with Kane defeating Shane in a Last Man Standing match at Unforgiven and an ambulance match at Survivor Series. During the latter event, Kane also interfered in a Buried Alive match between Vince McMahon and The Undertaker, helping McMahon bury The Undertaker and win the match. In January 2004, Kane took part in the Royal Rumble match; he was eliminated when he heard the bell toll from The Undertaker's entrance music, distracting and distressing Kane, and enabling Booker T to eliminate him. Over the following weeks, Kane repeatedly insisted that The Undertaker was "dead", only to be met with various paranormal incidents such as a rainstorm localized over the ring in which he stood. The Undertaker finally returned at WrestleMania XX (again sporting his "Deadman" persona) with Paul Bearer at his side, defeating Kane.
