Initial thumbnail sketch idea for Space theme alien prisoner "A limbless thing with wings and razor sharp beak and tail" Banshhe is a fully sentient creature. It can't articulate words but it understands a vast array of languages. The problem with Banshee is that doesn't like anything it hears and just lashes out in a very antisocial way. Which is bad news if you happen to be in an elevator with him. It's hoped he can be rehabilitated and prison is the safest place to keep him.
