Kamatari

is a small, seemingly one eyed wonder weasel holding a sickle with which it can cause a lot of destruction in a short amount of time. Its sickle is almost as large as itself. This mysterious weasel has only been seen twice for a few seconds after its summoning, once in the Sasuke Retrieval arc, and once in the final filler arc. After it starts moving, it can't be seen by the unaided human eye.
 * Name: Kamatari
 * Voice Actor: ???
 * Temari is the only person to summon it so far.

It is summoned using Temari's fan as a medium through, after which it slices down all in its path with enough force to decimate an entire forest.
