Biology

The Basculin native to the Hisui region are of a form known as White Stripe Basculin, which are the only form of Basculin that can evolve into Basculegion. This evolution occurs when a Basculin is possessed by the souls of other Basculin from its school that could not withstand the harsh journey upstream. Basculegion fights together with these souls, which attack opponents as if with a will of their own. Its appearance differs depending on its gender.
