Quirky anectode: I befriended an american hobo who travelled to Brazil in the 90's (he came here again every now and then). He didn't shower much, truly looked like a crusty vagabond, and when he found out about it, he absolutely loved the character named Capitão Feio ("Captain Ugly"), a dirty, crusty supervillain whose superpowers are spreading dirt around. Capitão Feio lives in the sewers and got his powers and he got crushed by all the dust and dirt of his huge, old comic book collection. He's also Cascão's uncle, and his goal is to become dirtier than his nephew.

edit: I don't know what he's actually called in english. Captain Ugly is the literal translation. By the way, 'Little Onion' is way cooler than 'Jimmy Five'.
