Waterwraith

The Waterwraith is a supernatural creature that has a humanoid shape and a translucent green-gray body. It is extremely dangerous, as it can instantly kill Pikmin by merely rolling over them, and can not be deterred or defeated until Purple Pikmin are used against it, as only they can stop it in its tracks and make it vulnerable to attack. Once it suffers enough damage, its rollers crumble and it runs about the area on foot, now harmless.

In Pikmin 251
In Pikmin 251, the Waterwraith is a boss enemy first seen in the Palace of the Wraith. Its behavior has been altered from, as the creature now moves faster and has more health.

In Pikmin 3 (Flish version)
They reappear, along with several new forms of the same creature, but have a new attack. they can teleport like a Honeywisp and will fall from the ceiling again, falling on Pikmin. other members, which are faster, cannot do this. Black Pikmin are good to kill these, along with Purples, because even in their jell form Black Pikmin can injure them. This takes longer, however.

In Pikmin 4 (Wii U)
The Waterwraith appears in only two places, Ghost Den and Paradise Forest during nighttime. At Paradise Forest, two Waterwraiths appear at first and a larger one appears later on.

In Pikmin Galaxy Adventure
It reappears, along with the Firewraith, Electrowraith, Magnetwraith, Acidwraith, and the Clambering Wraith, although the entire family is weaker than their counterparts in other games.

In Pikmin: The After Years
The Waterwraith is much stronger and appears along with the Firewraith, Electrowraith, Magneticwraith, and the two newly discovered Acidwraith and Clambering Wraith.

In Pikmin: Dimensional Breach
Waterwraiths are mostly unchanged from their counterparts in past games, appearing in various late-game dungeons alongside other Wraiths, including its cousins from Pikmin: Redemption. Waterwraiths make up the bulk of Derrick's army. Black Pikmin cannot harm Wraiths by themselves in this game.

In Pikmin: Redemption
The Waterwraith, along with the Firewraith, Electrowraith, Magneticwraith, and the Phantom, only appear in the Haunted Village, Crystal Palace, Tower of Babil, and Pit of Redemption. These creatures are extremely powerful and terrifying, but yield great rewards.

In Pikmin: The Winds of Light
The Waterwraith appears twice so far, both times in the Royal Wraith's Palace, once in the lower-right arena on Sublevel 2 and two of them appear in Round 5 of Sublevel 3. Also, in the Architect's Playground, hitting the wall on Sublevel 5 will trigger the sound of three Waterwraiths, yet none will appear.
