Duncan Foreman

A tough-as-nails mercenary hailing from New Constantinople, Duncan Foreman was once a two-bit lowly nobody who stole to survive the harsh brutality of his poor living conditions. When he entered his teenage years he started to assemble small gangs and conduct even bigger crimes with his coterie of chums. Much, much later, these dangerous activities led to the formation of his ever-so-insidious mercenary band, known as the Crimson Claws. A ruthless mercenary group dedicated to causing as much havoc as possible, whether it be murder, pillage or destruction of property.
Duncan serves as the main antagonist of Halo: Lone Commando, in which he fights numerous skirmishes with none other than a SPARTAN-II.
