Devilon

Devilon is the primary antagonist of the series. He is the last surviving Draikonian who almost conquered the Spirit Realm 2000 years ago. He was ultimately imprisoned by The Spirit Queen, but not before turning Chaos and 13 evil and taking them with him.

He was freed centuries later by Chase, and now the ghosts are wreaking havoc throughout the town of Appa Hills.

He plans to find the Ancient Stones and use them for his own heinous purposes.
