A little about him: Pax is barely sentient so he can't talk or understand others very well. The fire flaming on his body is to help keep him cool (like how humans sweat and canines pant) and he can also breathe fire. In colder climates his body will generate the fire to keep him warm and heat his surroundings, but doing this for long periods of time makes him very hungry. He's quite friendly, but often wary of strangers.

Though this reference does not show it, the inside of his mouth is purple like his scarves. The blue flames were heavily inspired by the anime Ao no Exorcist.
