Batfink is a superpowered anthropomorphic grey bat in a yellow costume with a big red "B" on the chest and red gauntlets and boots. He uses his super-sonic sonar radar and metallic black wings to fight crime. In the last episode of the series ("Batfink: This Is Your Life"), it is revealed that he obtained his powers when he was born in an abandoned plutonium mine and that he lost his natural wings as a child while saving his mother's life, after escaped convicts blew up their mountain-top cave. This incident is what motivated him to become a crime-fighter.
Batfink lives in a split-level cave, and has a direct video link to the Chief's office.
