Roman Groom was an American member of the group on Bowie Base One. He was the designer and operator of the robot Gadget, giving it its "comedy" persona.
A child genius, he had multiple degrees by age 17 when he decided to sign up with NASA. He was the youngest member of the Bowie Base mission, noted to have an instinctive talent for mechanics.
When escaping the base, he was infected by The Flood when a single drop of water fell on to his cheek. He warned Adelaide Brooke and the remaining members to run before he transformed. The infected Roman was killed when Adelaide blew up the entire base. (DW: The Waters of Mars)
