Delzaine

The current king of Endora. For reasons unknown, he wants to revive the Babel, a contraption that once connected Endora to the surface. It's said that he murdered Emilio's father, the former king, but there's no definitive proof. He may have a relationship with Shun's father because in the first episode there was a scene where they are having a conversation in front of the Adamas and in professor Asanaga's hands is the crystal that pulled Shun into Endora. It is revealed that Delzaine may be aware of the phenomenon that is causing the Warp particles in Endora to decrease because the incident began to take place after he was named king.
