WrestleMania, supposedly the greatest stage of them all. But people at the Madison Square Garden or watching WrestleMania XX on Pay-Per-View knew that only one man would prevail in the main event, a fatal-four way match between Randy Orton, HHH, Kane, and the Undertaker for the World Heavyweight Championship. Only one championship had changed hands that night. Rey Mysterio had won a sixteen-man battle royal for the Cruiserweight championship. Fire exploded from the entrance ramp, and Kane came out. He went to the ring, raised his arms, and brought them down, making fire come out of the ring posts. HHH came out next, holding his title. Randy Orton came to thousands of boos. Everyone waited for the Undertaker's music to come on, but it never did.
Instead, Eric Bischoff came out, claiming that the Undertaker was not going to show up, for reasons unknown. "Now," he said," the original fatal-four way match is going to be a-" Just then, the lights went out, and a gong was heard. The lights came back on, and Undertaker was in the ring, behind everyone. Eric saw him first, and ran. Every one in the ring turned around and got out of the ring. As soon as HHH and Orton were out, they went after each other and started fighting. Undertaker waited, hoping there would be a triple count-out and he would get the win. But then he realized he would not get the title unless he won by pin-fall or submission. He got out of the ring and irish-whipped Kane into the ring apron. He then threw him in the ring.
Randy Orton and HHH were still brawling outside the ring and, even though the count had restarted, they were counted out. "The winners of this match due to double count-out are Kane and The Undertaker. HHH is still, however, the champion," the announcer said. Just then, Mr. McMahon came out. "There can't be a tie. The match is now a one-on-one match between Undertaker and Kane." Undertaker instantly irish-whipped Kane into the turnbuckle. He then punched Kane. They fought for a while until Kane made a comeback by delivering a chokeslam to Undertaker. He waited for Undertaker to get up , and then he tombstoned him. Undertaker sat right up and delivered Old-School to Kane. Afterward, he delivered a chokeslam and tombstone to Kane, but before 'Taker could pin him, HHH attacked the referee from behind. Undertaker ran towards HHH and clotheslined him over the ropes into Randy Orton. He then picked up the referee and dropped him right next to Kane, then pinned Kane, winning the title.
