Plasm Wraith

The Plasm Wraith 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. Plasm Wraiths are intelligent creatures that show obsessive traits not seen with other creatures of PNF-404, holding even a Leader captive with what appears to be curiosity rather than maliciousness. Efforts to take what it has claimed cause the being to become the Mysterious Life Form and slowly ooze towards it, attempting to retake it, until the possession in question has traveled far enough. Once this occurs, the Plasm Wraith assumes its golden humanoid form, locks the possession in its core, and begins to attack.

After the Mysterious Life Form transforms into the Plasm Wraith, attacking it will cause small bits of its plasmic exterior to fall off, making its health go down. However, Pikmin must then attack the puddles of plasm on the ground to destroy it, or the Plasm Wraith will simply reabsorb the puddles and regenerate health.

It will actively attack Pikmin but mainly prefers to target the leaders and attack when they are close, by skewering them with a rapid "needle-arm" attack. If any Pikmin aside from Rock Pikmin are in range of this attack, they will be skewered and eaten. While it is doing this, it will not be fazed by attacks, and can easily kill the Pikmin. Instead, throw just a few Pikmin at it until it tries to shake Pikmin off by twisting its body. This will cause additional plasm to fly off of its body. As it loses more and more plasm, it decreases in size; this is the key to winning the fight. It can also become temporarily airborne, during which it can be reached by Winged Pikmin, or, with some effort, Yellow Pikmin. If it is hit with enough Pikmin while flying, it will fall down, losing even more plasm as it hits the ground.

Plasm Wraiths have also displayed the ability to sacrifice a bit of plasm to create illusions that are capable of recreating the physical form and behavior of whatever it is mimicking.

Elemental Plasms
After a quarter of its health is depleted, the boss will attack by spewing large masses of plasm onto the arena, then spitting out a small, golden patterned cube. The plasmic mass will form around this solid cube and transform into an Elemental Plasm. Each Elemental Plasm has a specific hazard associated with it. If the Wraith spits out a cube, quickly call all Pikmin away from it. The less plasm in the Elemental Plasm, the less time is needed to destroy it. It has many forms, each of which can only be destroyed with certain Pikmin types:


 * A bubble of water, with the cube in the middle. Blue Pikmin must be thrown in, so they can swim to the core and shatter it. Other Pikmin will gain a bubble of water on their stem if they touch the hazard, and will suffocate if not called back.
 * A bed of fire surrounding the cube. Red Pikmin are recommended, but Rock Pikmin can get the job done as well, provided they are whistled back before they burn to death upon touching it.
 * An electrical sphere. The Elemental Plasm will form a spike underneath the cube, setting it high up in the air, and will then generate an electric barrier around it, making it resemble a . Only Yellow Pikmin can reach high enough and sustain the forcefield.
 * A crystal cube with the Elemental Plasm inside. The cube slowly tumbles around the stage, crushing Pikmin. Only Rock Pikmin can break it, chipping away different shards at a time.

Destroying Elemental Plasms will leave behind a large amount of plasm that must also be destroyed. If they are left there for longer than twenty seconds after being initially spat out, the Plasm Wraith will reabsorb them to heal itself. After the boss has been reduced to just a quarter of its health, it will create three Elemental Plasms at once.

In Fanon Games
In Pikmin Ultimate, it acts as a mini-boss of the cave, Ghoul's Resting Place. It is substantially easier than in Pikmin 3, as it has fewer hit points and has lost its elemental plasm attacks. However, its stabbing attack is longer and it is faster from the original. It can also become the Mysterious Life Form for a brief moment of time. Other than speed, the more dangerous stabbing attack, and the ability to transform, the fight isn't much different.
