His powers are even more depressing. Aviax has the amazing ability to transform into any bird, one of the many creatures in nature less capable of fighting crime than a regular human. And because life was not miserable already, they gave him a weakness as if his entire self wasn't weakness enough: Aviax has hollow bones, like real birds. Which is OK for them because unlike Aviax, birds are not going to get into fist fights with super villains.
