Darklon is a character from the G.I. Joe: A Real American Hero toyline, comic books and cartoon series of the 1980s. He is affiliated with the Iron Grenadiers as the Evader driver and debuted in 1989.

Darklon is a distant cousin of the Destro clan, and the last of a long line of privateers, mercenaries and investment bankers. He lives in a cast-iron castle in the Alps, from where he dispatched his private armies to do battle for the highest bidder until Destro called for his help in a bid to take over Cobra. Darklon is motivated purely by greed, and is completely unhindered by ideology or ethics.
