Mysterious Life Form

The Plasm Wraith, better known as the Mysterious Life Form, is the main antagonist of the second season of The Lost Pikmin.

It is an ancient and powerful spectral entity who was once defeated and sealed away in a box by The Elemental Pikmin long time ago, until the second season of the show, where it was accidentally freed by Sparkles when the Phantom Pikmin unnoticed sent him searching for a "shiny treasure". Then the Life Form proceeded to attack/destroy Pikmin villages and other buildings (including Plum & Violet's house) seeking to absorb Sparkles for freeing it, even getting to absorb the Phantom Pikmin (who was preparing to hypnotize it).

Luckily, after Cotton tells his companions its history, the Pikmin Friends made teams and reunited the Elemental Pikmin, thus making their ways to Captain Indigo's village, where they fought and subdued the Mysterious Life Form enough time to vanish it from PNF-404 with the Special Combined Elemental Attack, sending it to its origin dimension not to be seen again.
