A British Joe agent and Pilot of the Dragonhawk Heavy Armored Drop Ship, Lt Stone is a covert-ops specialist and an old friend of General Hawk and Duke.
He was an elite member of a well-known British intelligence agency. He prefers to be called a spy rather than a covert ops agent, because "spy" accurately describes the daring, devious and dangerous nature of his work. He is highly skilled at cracking codes, reading ancient languages and solving mysteries. His fascination with secrets has led him to collect many gadgets with hidden weapons and devices. He is an expert at disguise and often infiltrates Cobra dressed as one of its members. An experienced pilot, Lt. Stone flies the Dragonhawk heavy armor dropship. His left arm, injured during a battle with Cobra, has been replaced with a bionic arm made of ultra-hard dimantium metal.
