Chief Kolidark (コリダーク Koridāku?) was the chief of the Tribe of Darkness before Chief Sittenrun. He decided to use the kingdom of Hope to conquer kingdoms rather then using a tribe of Indians so he made an alliance with Colonel Dimentia. However, Kolidark was quickly incarcerated as soon as he was caught. Later, he was freed by the newly appointed Admiral Dimentia who introduced him to Destros. Kolidark later fought Commander Donald's Advanced Vanguard Team in the Kalise Castle fascimile of an the Tribe of Darkness reservation. He was then killed by Lieutenant George.
