Darklon's family is related to the Destro clan. Like his distant cousin, he wears a steel mask of his family's design. Whereas the Destro clan made their fortune in arms dealing, the Darklons established their business in mercenary work, privateering and investment banking. They choose no sides, preferring to work for anyone who offers the highest bid. Darklon further distances from Destro in that he does not share the same scruples or operate under some kind of moral code or ethics. He is motivated purely by greed.

Darklon was part of a unit of Iron Grenadiers used by Destro in Sao Cristobel when the latter sold a nuclear warhead to one side in the country's civil war but arranged for the helicopter carrying it to crash. Darklon was sent in command of a team of Iron Grenadiers under to recover it before a G.I. Joe Team reached there first. En route a peasant girl warned him "Beware the dark man... he will be your downfall... I have dreamt it..." but Darklon was dismissive. However Darklon's team and the Joes were beaten by a Cobra team headed by the Baroness.
Darklon and the Grenadiers returned to Destro's temporary base which they unsuccessfully defended against an attack by the G.I. Joe Team, who sought the remote control for the warhead. During the battle Destro was thrown out over the edge of a cliff and Darklon, believing his salary gone, contemplating selling the remote control to Cobra but he was overpowered by the Joe Snake-Eyes (the "dark man") who took the control and used it to take the warhead from Cobra.
