Blackbird

Blackbird is a melanistic cat with dove wings and a missing leg who was  cast out by his family, who viewed him as a curse. His father attacked  him on the way out. He now lives with a group of other castaways. They  are serious and pessimistic, tough on the outside, secretly caring  deeply beneath his tough exterior. He takes on a parental role for those  in his group, hoping to fill the void his family left him with.

Their markings are completely optional, and they've been through a few redesigns over the years, so don't worry if some art has different designs! They're pretty fluid.
