plasm wraith
Final boss of Pikmin 3. A giant, vaguely humanoid creature made of golden plasma, notably having a hole on its face. Attacks by using its "arms" as spikes or by turning into puddles of plasma that are also elemental hazards.
It takes Olimar captive and is very protective of him for unknown reasons. When Alph, Brittany, and Charlie try to rescue him, it chases them through the Formidable Oak and fights them explicitly to keep him.
