Yeaah, they were human, and might've been the first vigilantes before the JL formed. Might've gotten caught by some mad scientist cultists. Might've gotten gene spliced a bit, but shhh. Don't worry about it :) They're fine. Absolutely Fine. This is Fine.
But anyway, they have wings now. And talons. And a lot of other things they have to adjust to and might straight up not have a civilian identity for a while- becomes more than a bit of social recluses while they figure this shit out.
So anyway, I haven't finished drawing or designing them, if I ever will, so have what each is based off of. There's a lot of robins. :) Also have how old everyone is at the start of the story. (Timelines are a fake thing that never make sense)
