Malleus is often seen as someone with a powerful presence and a distant demeanor, however, he can become very protective of the things that are important to him. Despite his calm and respectful yet cold personality, he also has a naive and childish side. He's incredibly skilled with magic, but struggles with most modern technology. He can be rather clingy with those who he's close to, and struggles to control his dragon instincts during mating season, though he's embarrassed about admitting it.
