Electrowraith

The Electrowraith is a terrifying creature that is very similar to the Waterwraith but with a body made of electricity instead of water. Much like the Waterwraith, it falls from the sky or cave ceiling, rolls around on two stone rollers, and relentlessly chases nearby leaders.

As the Electrowraith's body is made entirely of electricity, Purple Pikmin that are thrown by it to make it vulnerable will die upon contact with it; Yellow Pikmin are unable to successfully attack it when it is not made vulnerable by Purple Pikmin. Luckily, a Dual Bud can be used to temporarily combine the two Pikmin types to create a Purple-Yellow Pikmin which will eventually split into the two Pikmin that formed it. Purple-Yellow Pikmin are not only able to make the Electrowraith vulnerable to attacks, but they can damage it too. Once the Electrowraith has run out of health, its rollers with crumble and the creature will begin scuttling around the area it was fought in, electrocuting any Pikmin it walks through that are not resistant to electricity. Continuing to attack it with Purple-Yellow Pikmin will eventually result in its defeat, where it falls onto its back and vanishes into nothing.

In Pikmin: The After Years, this enemy will drop two randomly-colored 20-pellets and one 10-pellet after defeat.
