The overall body resemble the body type of chinese dragon, with a big mouth and four clawed hands. It also has two huge horns and long tail. Historians and scientists suggest that his main scaled-body color was black and gray and his eyes were light blue.

Some legends say that Exorade was from the moon. Some says that he was from the core of the planet and some even says he was from the Lost Zone. Yet it's original home is unknown.

Before the death of Narakos, Exorade was slayed by the god of death. After killing Exorade, Narakos burned his flesh to make ash and then used the ash to create the 10 Gemstones. Narakos left the remains and legends say that Drakern stole the bones and put it in the Ghost Zone.
