Dokan (Power Cell)

Dokan was the master of Tengobushi who arrived on Earth in the 21st century to retrieve a Kamishi energy cell.

He himself belonged to a higher Kamishi caste rather than to Tengobushi and could change his appearance at will. (AUDIO: Death in Geneva, The Battle of the Tower)

When Kamishi masters arrived on Earth, they considered his mission complete, ending his existence. (AUDIO: Ice Station Alpha)
