"There's not a lot that can shatter Cobra Commander's resolve to rule the world but this guy comes close. Calling himself 'Sigma' this enormous android or rather Repolid as X says they're designated, well he's as brutal as they come. Apparently he has gained control of most of Cobra's resources at the moment and has every last Viperoid after X and us Joes. We're going to need something amazingly powerful to win this war...Hawk out."
GI Joe Alterverse figures have returned and here's the menacing Sigma from the Megaman series for you! A compilation of different Sigma designs this Reploid was made from a Target Exclusive Justice League Lex Luthor, Avengers Thunderstrike Thor legs and arms, and various Gundam/DCU Cyborg/fodder parts for armor. He's fully articulated now where the original Brave and the Bold style body only had 7 points of articulation. Sigma also has his Beam Saber and a cape from a movie Superman to complete his Alterverse look.
