Regulus Corneas is an unremarkable man with a youthful appearance and white hair, skin, and clothing. Regulus is talkative and highly prideful, viewing himself as a divine being and the most satisfying existence in the world. He is extremely selfish, hypocritical, and sociopathic, often forcing his own selfishness on others and justifying his actions. He tends to become angry when his beliefs are challenged and accuses others of violating his rights, killing them without mercy or second thought.
