Scorpio was Zartan's associate who assisted him in his plans. He was a short, possibly human individual with his head wrapped his bandages, and was missing his right arm. The limb was replaced with a robotic arm equipped with a laser gun. When Jonny Quest and Hadji Singh infiltrated Zartan's lair, Zartan ordered Scorpio to kill them. He tried to shoot them with the weapon attached to his arm, but was picked up by Hard Rock and thrown against a control panel, which electrocuted him. He later died when Hard Rock caused Zartan's entire lair to come crashing in on them.
