Magnus is a rotund, reddish-orange elder dragon with spikes on his body and wings, and a tuft of hair like a topknot. His appearance is reminiscent of a sumo wrestler, complete with a necklace and a loincloth like a yokozuna's rope. He is a proud glutton who swallows his food whole and enjoys teasing people by wiggling his large, soft belly. Personality-wise, Magnus is headstrong, tough, boastful, and brutish, yet also possesses a father-like demeanor. He is a capable fighter who can use his bare hands in combat.
