Return

Return is a Normal-type charged attack. This attack is taught to a Pokémon that has been purified as a replacement for Frustration.

Return is retained by Purified Pokémon if evolved. Unlike Frustration, a Charged TM can be used to change it, and it would be overridden by community day exclusive moves if applicable.

Trivia

 * This attack was added with the release of Shadow Pokémon.
 * Return does not seem to have any animation of its own; upon using it, the Pokémon would only perform its normal Charged Attack animation without additional visual effects.
