Deadly intelligence is the easiest way to sum up Malysuss's disposition. He is always looking for the most strategic approach to a situation, as well as likely the most sinister. While he does care about his rather strange bond, one could never call him "affectionate". Then again, how could one be particularly affectionate with a ghost?
