'Him' is a term that can refer to both males and androgynous genders. Since the gender of Pokémon is not typically outright stated, the gender would default to 'him' since it is a term that can be used for things with unknown genders.

And besides, this is Smash Bros. specifically, and in these games, the Pokémon characters do have a specific gender.
