Pokémon Ranger: Shadows of Almia
In Pokémon Ranger: Shadows of Almia, Dialga is available in a Special Mission. At the beginning of the mission, it uses Roar of Time to send the player and Wendy back in time to before the player moved to Chicole Village. If the player fails to capture Dialga within a hidden time limit, Dialga will send them back to the beginning of the mission.
Effect: The user cannot attack the next turn after this move hits.
Grid assumes the user is in the square marked by > facing to the right. Orange squares indicate spaces that are hit. Red squares indicate the knockback on hit Pokémon. A blue square indicates the user's position after performing the move.
Dialga's eyes glow orange and the diamond on its chest glows blue. The fins behind it grow larger and Dialga opens its mouth, an indigo ball forming in front of it. It then fires an indigo beam from the ball at the opponent. After the attack has been fired, the fins on its back shrink back to normal size.
Dialga's diamond on its chest glows blue, then a small purple and black ball grows in front of its mouth, until it becomes nearly the size of its face. It then shoots a black, purple, and white beam from it, with white gusts of aura bursting from the beam as it is fired.
