The Plasm Wraith (アメニュウドウ, Ame Nyūdō) is the final boss of Pikmin 3, and is responsible for capturing Captain Olimar. It is a virtually featureless, vaguely-humanoid Waterwraith-like being made entirely out of a cellular protoplasmic mass, which allows it to split different parts of its body off to create other semi-independent entities. It is fought in the Formidable Oak. As with all final bosses, the path leading up to it, and/or the boss fight itself, requires the knowledge and utilization of every single Pikmin type.
