They can be evolved into six different types:

They can be further evolved into Void Bringers. Note that Shadow Bringers have different options for Void Bringer evolution than Shormy do.

A supporting spirit whose primary role is to spread shadow, which they do at the start of every turn if they're standing on shadow. Shadow Bringers are rather weak and unable to attack, unless you evolved a Magic Type that learned ShadowBlast as its only means of damage.
