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.

It is summoned using Temari's Iron Fan as a medium through the Summoning: Quick Beheading Dance, after which it slices down all in its path with enough force to decimate an entire forest.
