Transformed Master of Weapons
Real Name: Duncan of the Viper Clan
Duncan heroically served King Randor throughout their battles with Skeletor and the Snake Men as Eternia’s chief war strategist and weapons maker. Exposed to the Serpent’s Ring, Duncan was magically transformed by King Hssss into a snake man permanently. Under this evil spell, he used his genius to create great and horrific machines of war for the Snake Men as they battled for control of Eternia. Eventually, Duncan was forced to battle against Clamp Champ, who had since replaced him as Royal Man-At-Arms. In their epic final duel during the Second Ultimate Battleground, Duncan was mortally wounded, but not before momentarily recovering his humanity thanks to a spell cast by his daughter Teela, the new Sorceress of Grayskull.
