#4 Showdown with the Dead Man
After the Undertaker won the 2007 Royal Rumble match, he began to play mind games with the three world champions. WWE Champion John Cena, ECW Champion Bobby Lashley, and World Heavyweight Batista had the unfortunate opportunity to become the Undertaker's next victim.
On the February 5th,2007 episode of Raw the Undertaker chose to challenge Batista for the World title at WrestleMania.
Undertaker and Batista had a decent feud leading to their match in WrestleMania 23 which saw the Dead Man slaying the Animal to win his first World Heavyweight Championship and extend his streak to 15-0.
Though Batista was on the losing end on the match, being in the ring with the Undertaker at WrestleMania is one of the most significant achievements in a superstar's career, and Batista had achieved it very early in his career, which iterated the trust Vince McMahon had in Batista as the future of the WWE.
Batista also squared off against the deadman on multiple occasions for the world title on Smackdown and other WWE pay-per-views.
