Keanu

Based on a real phenomenon, Keanu purely serves host to a Tau demon. Originating from Makana, Hawaii, the legend states that the fallen foes of fights eventually rise up to grant death to those who opposed. Unfortunately for this Espeon, no trait or sign is original to its host. Tau demons are supposedly made from the ground up to deal as much damage as possible, and unfortunately this leads to little to no defense. They can and will use any form of means to destroy a threat. It sounds scary on paper, but they have been observed to be harmless to humans.
