Billy Bat

Ostensibly a talking anthropomorphic bat that is the star of several detective comic book series throughout the 20th Century. His true nature and purpose comprise the central mystery of the plot. Francis Xavier himself once mentioned the Bat himself unsure if the entity was an angel or demon or perhaps both. Zf on the other hands claims there are two bats one white and the other black. When The White Bat appears it always says confusing things and when The Black Bat appears it manipulates people to do bad things.
