Dr. Nikolic

He was once the most promising doctor in the Mortem Realm. However, he became obsessed with gaining knowledge and power, which slowly eroded his sanity. He began performing morally questionable experiments and disregarding any ethical considerations until he became what he is now. He's polite with those around him, but he can quickly fall into dangerous impulses, causing danger not only to others but also to himself. At first glance he might look and act like a sane individual, but once his facade cracks up, he reveals his true, deranged self.

He enjoys experimenting on other demons, since they have reduced pain sensitivity and quick regeneration. If there aren't any viable subjects, he won't hesitate to experiment on himself. His goal is to uncover all the secrets of the diverse species in Mortem, and dreams of dissecting a living human. He is strictly forbidden from traveling to the human world; Lillium and Razru have a close eye on him. Lillium completely despises him; Nikolic would enjoy having Lillium into his lab, intrigued by his nature as Dalvan's creation.
