Using what I've learned, I decided to update Balthazar the bat to a more fitting look.

Balthazar is a thief at heart, using seduction and the power of dimensional movement, he's able to lift quite a bit of cash.

Although he is agile and is able to use his wings to glide, his frame is small and flimsy. His bones are similar to that of a birds, hollow save for a few supports. Due to his nature and body structure, he's also quite gaunt, sometimes to the point of looking unhealthily thin. He claims he's as healthy as a horse, but his friends still worry.

By the way, yes, his arms are indeed that long.
