A gymaholic mound of muscle who's either at the gym, or using the weights bench in his living room, in a bid to get rid of his chubby, youthful looks. Most likely to be found constantly flexing in front of 6th formers and frequently spraying them down with his mr muscle spray.
Captain Flex's movement resulted in such a gun show that it caused his jeans to rip. "Damn you fifteens!"
