Batista entered the Royal Rumble 2005 and won it, thus earning a right to challenge either Triple H or JBL for their respective titles at WrestleMania 21.
The Game wanted Batista to challenge JBL, and staged many incidents to develop a feud between The Animal and JBL.
However, on the episode of RAW where Batista had to choose between the two champions, Batista gave a thumbs down to Triple H, reminiscent of Triple H turning on Orton a few months ago. The Animal attacked Triple H, and signed the contract for the World Heavyweight championship - thus weakening Evolution.
