Maleus is a demon possessing dark magic, supernatural strength, high agility, and runs at an unnaturally high temperature. He views humans as lesser beings, though his mind may be changed with time and effort. He is incredibly intelligent, but this only adds to his arrogance. Most of all, he is manipulative. He will do and say whatever it takes to get his way. He is likely to form a tight bond with the human he meets first in his newly exiled state, never wanting to let them go.
