Leon is stubborn, pigheaded, proud, resourceful, mildly ill-tempered, but overall compassionate and has a major soft spot for pups and young children. Though Leon is only willing to devote himself to a single handler despite this love for young humans and pups, many humans have attempted to gain his alliance through many, many means but they never once managed to bond with him or break him. Having spent majority of his life, including his pup-hood and teenage stage on his own, this Toko understands more then anyone what it is like to face one conflict or danger after another. His pride however makes it almost impossible for the beast to cow down or admit weakness, this makes training him difficult and working through things even harder.
