Corcus, is the Black Aquitar Ranger of the Aquitar Rangers.
He is also referred to as Black Alien Ranger on Earth, as well as Mighty Morphin Alien Black Ranger.
He is the quietest member of the team, often lurking in the background, but he fights with extreme ferocity against his enemies.
During the invasion of the universe by Dark Specter's United Alliance of Evil, Corcus and the other Aquitian Rangers battled Divatox's army on Gratha, where they were defeated. They were later saved by Zordon's Energy Wave.
