Unlike the previous Mystery Dungeon games, the Adventure Squad Series has the inclusion of the Alternate Coloured Pokémon. Like in the main games, these Pokémon are incredibly rare and will likely not be seen by most players. As such, when you get them, you'll have to do your best to recruit them
Differences from Normal Pokémon
Unlike the other Pokémon, the Alternate Coloured Pokémon within this game do have an added bonus. Their Hunger stat is always 200 as opposed to the 100 of normal Pokémon. This makes these Pokémon incredibly worthwhile for the larger dungeons and great as a base for the Pokémon Towers.
Aside from that change however, the Pokémon essentially remain the same apart from the aesthetic change.
