Kingdom Hearts Birth by Sleep
Xehanort uses Vanish while battling Terra, Ventus and Aqua separately in the ruined Land of Departure. The major difference is the spell lasts longer, making him more lethal as he uses his attacks. He cannot be locked on and can only be tracked via his blades. The best way to survive this is to keep dodging and use the finisher of the Rhythm Mixer Command Style to end the battle quickly.
