EG:Luigi has always been the human face of the Super Mario Bros. - and let's face it, they could do with one. Irrepressible, indomitable, upbeat to a frankly rather irritating fault, Mario - who meets every situation with a WOO-HOO! - is a global icon for a reason, but that reason is not that he's easy to identify with. He started out as an everyman turned superhero, but he's since become an abstraction, a squawking bundle of heroic momentum hiding behind a moustache. He's loveable, but not exactly likeable.
