Marill is a Water/Fairy-type Pokémon (originally a pure Water-type until Generation VI) that first appeared in Pokémon Gold and Silver. It evolves from Azurill with high friendship (starting at Generation III) and evolves into Azumarill at level 18. In Super Smash Bros. Melee, it can be spawned from a Poké Ball and attacks by using Tackle, which involves it running in a single direction, launching back any opponent who gets in its way. Marill continues in the opposite direction if it hits a wall; if it ends up in an enclosed space, it continues to bounce back and forth until it disappears.
