An American scientist born in Oshkosh, Wisconsin, Gideon stands 5'10" tall and tips the scales at 173lbs. He's lean but not particularly muscular. He wears his black hair in a kind of short bob. Blue eyes and lightly tan skin help him look younger than his 27 years.

His codename is Rose, but the color of rose used indicates certain condition: red = injured and needs medical attention, black = critical condition and needs immediate medical attention, yellow = compromised identity or position, white = coast is clear, pink = dangerous female present--beware.
