Celebrate is a unique ability that is exclusive to Pokémon event distributions. When a Pokémon with Celebrate uses the move, it does not deal damage or inflict status conditions. Instead, it triggers an in-game animation where the Pokémon appears to celebrate a special occasion, complete with confetti and joyous music.
Celebrate, as a move, essentially functions as a non-competitive, novelty ability, primarily serving to mark special events, such as anniversaries or promotional giveaways. It holds a special place in the Pokémon community as collectors often seek Pokémon with this move for their rarity and unique appeal.
Interesting Facts:
Event Exclusivity: Celebrate is not obtainable through normal gameplay and can only be acquired on specific Pokémon distributed during special events. For example, event-distributed variants of Pikachu or Eevee might come with Celebrate as a signature move.
No Battle Impact: Because Celebrate does not impact the status or health of the opponent or the user, it carries no strategic advantage
