First Oni

The First Oni was, as its moniker indicates, the first oni created by Fu Leng. As the bearer of the true name of Fu Leng ("Fu Leng" is a false name for the Ninth Kami, and his true name has been lost to the ages), the First Oni is the most powerful oni ever created.

The First Oni's form is defined by its shape-shifting abilities, which allow it to create appendages and limbs out of its own body.

The First Oni was present on the first Day of Thunder. It killed Mirumoto during the battle in Fu Leng's keep, and left Hida Atarasi to become corrupted. Some time later, chasing the fleeing Shosuro and Shinsei, it was confronted by the Kami Shiba, who had come to save the remaining Thunder. The First Oni and Shiba traded mortal blows in the ensuing battle, and both died shortly thereafter. (DotE pp. 107-08; Jade p. 123; Phoenix pp. 5-6)
