Shippō's father

Shippō's father was killed by the Thunder Brothers, causing Shippō to seek revenge on them, first by stealing jewel shards from Kagome and Inuyasha. After hearing his story, Kagome and Inuyasha eventually agree help him, and the Thunder Brothers are killed by Inuyasha. During the battle, Shippō's father's spirit protected Shippō and Kagome from harm using his pelt, which the Thunder Brothers had stolen. When Shippō's father was killed, his fur was used by Manten as a decorative sash.

It is interesting that while Shippō's father takes a form of an actual fox or an animal that resembles a fox, Shippō looks more humanoid. It could be that that's Shippō's human form.
