The main feud heading into WrestleMania on the Raw brand was between Triple H and Batista for the World Heavyweight Championship. Batista won the 2005 Royal Rumble, last eliminating John Cena, earning the right to participate in the main event of WrestleMania 21 against the World Champion of his choice. In an attempt to persuade Batista to challenge WWE Champion John "Bradshaw" Layfield rather than Batista facing Triple H at WrestleMania, Triple H concocted a scheme to have Batista run over in a limousine resembling the one used by Layfield. Initially, Batista did not want help from Evolution and wanted to confront JBL by himself. Triple H insisted that Evolution accompanied Batista anyway, saving him from the oncoming limousine. Batista became aware of the plot while eavesdropping on fellow Evolution members and signed a contract guaranteeing him a match with World Champion Triple H at WrestleMania, thus leaving Evolution and officially turning face. Batista pretended to sign with the SmackDown! brand, giving Triple H and Flair the "thumbs up," but turned it into a "thumbs down" before attacking the pair. This lead to Batista's departure from the stable.
