In the anime Crusher Joe: The OVA's, Ghellstan is a dictator who rules the planet Kabara. He is described as a cruel and oppressive leader who maintains power through brutal measures. His most notable action is the operation of a slave labor camp located on a frozen comet orbiting Kabara. This comet serves as a prison where political dissidents and other prisoners are subjected to forced labor under inhumane conditions.

Ghellstan's role in the story is that of an antagonist who creates a significant crisis. When an industrial accident in space alters the comet's trajectory, threatening to send it crashing into the planet Kabara and causing massive destruction, Ghellstan's cruel regime has turned the comet into a floating prison camp. This situation directly endangers the lives of the prisoners he holds there. It is this impending disaster that prompts the hiring of the protagonist team, Crusher Joe, who are dispatched to alter the comet's course and rescue the prisoners, making Ghellstan the source of the central conflict in the OVA episode "The Ice Prison."
