Ok well.
the picture attached is a reference for skin colour and his outdated visor.
His pants are just like any other big bro pants except they are a tad darker with Orange lights and Actual pads on the bottom to support him instead of balls.
His skin is the off greenish grey you see here. littered with the odd scar here and there. he's also a tad bigger that usual big bro sligs and carries a Huge hacker Strapped to his back (( think super sized vykker hacker. ))
if the pants are a tad too difficult just draw em without em looking rather peeved XD
