Lord Flashheart is boisterous and an arrogant womaniser, attractive to all the women he meets. He is extremely popular among his peers and becomes the centre of attention whenever he enters a room, usually by bursting through a door in a spectacular fashion. The two Flashhearts are stereotypes of a certain kind of hero (the Elizabethan swashbuckler and the World War I flying ace), slanted to emphasise the negative qualities associated with such characters such as narcissism, sexism and promiscuity. His catchphrases are "Woof!" and "Let's do-oo-ooooo it!", while suggestively thrusting his pelvis. He commonly uses sexual innuendo in ordinary conversation, for example, "Am I pleased to see you, or did I just put a canoe in my pocket?" Rik Mayall later recalled, "I was surprised when they asked me. Very honouring that they asked me. 'Alright,' I said, 'I'll do it as long as I get more laughs than Rowan.'"
