Amadeus, the "angel".
He has a human form, but it's not shown here. He can shift freely between the two forms, but prefers his beastly self for various reasons.
His demeanor is relatively benign, if somewhat guarded, and will shy away from conflict more often than he'll seek it. His past hangs over him and trust is not often one gained from the poor thing, often bonding to one person and defending them for life.
He is afraid of birds and snakes. In his dreams, he is haunted by both.
