Loudred fights alongside Sunflora during the fight against the three Haunter. He functions as a companion Pokémon rather than as an ally Pokémon, granting him a fixed moveset.
Despite the warnings given in the Special Episode about Sunflora's type disadvantage, not only are there no Fire-type Pokémon found in Spring Cave (aside from two Slugma in a cutscene) but over a third of the Pokémon in this dungeon are weak against Grass-type moves.
