This is Brattle! He’s actually based off of a species of pet on Subeta, known as the Lasirus:
All I know about him is that his name pretty much defines his personality—he’s a brat. He also has a fear of flying, which is why he doesn’t mind covering up his wings with his hoodie. While he was first learning how to fly, he crashed face-first into a wall and his nose basically crunched. Because his appearance was altered so drastically, he refuses to fly. Brattle also holds talented flyers in contempt, possibly out of jealousy. He’s still young, so he still has plenty of time to get over his phobia and take wing.
I went with a more “traditional” bat design for this guy—big, big arms and puny legs. He’s pretty top-heavy, but then again, so are bats. Look at how tiny this guy’s feet are in comparison to his wings and upper body:
Now, technically, Brattle’s design isn’t quite accurate to the Lasirus’. The Lasirus is more of a cross between a bat and a rat, and thus has longer legs and feet. But I’m not too concerned about it. I think the tail works well to make it clear that Brattle isn’t designed on a real species of bat.
