I think from looking at his scenes and hismelf that I know what he will drop in the future.
Drakath;s Armor - Avatar Equip
Drakath's Sword - Avatar Equip
Drakath's Cape - Avatar Equip
Drakath Morph - Avatar Equip
Drakath Dark Morph - Avatar Equip
Drakath's Sword in Ground - House Item
Drakath's Chair - House Item
Chaos Beast Wheel - House Item
Yes I do not have an exact name for the ancient wheel that glows when a Chaos Beast is awakened. But I DO know that Drakath has possibilities of dropping all these items. So be prepared to pwn!
