Animēshon

The Animēshon are corpses that III creates from scratch and are animated by Isis' Devil Fruit, the Sonzai Sonzai no Mi. They are separated into levels depending how much detail is put into them and their strength.

Mugen sells these beings in the Underworld for a profit depending on the level. And, if the buyer asks for them to be "custom-made", then the price will increase.

Overview
The Animeshon are artificially made beings with III and Isis being their creators. III creates everything within his body with the usage of his blood via the Shukketsu Manipulation Technique. However, this results in his blood loss, having him have Hepen be there when III is creating the bodies. Depending on the level, the time frame it takes to make them is rather large. If a corpse doesn't have all the required pieces in which it needs to be animated, Isis cannot animate the corpse, and as such, will be deemed useless and tossed away unless it can be modified so the corpse is complete.
