Wario and Waluigi are two of gaming's goofiest characters. When painted in noir shades, they make surprisingly convincing heavies. This beautiful artwork from Flickr user Charity Ryan shows no there is no honor among Mario Bros. criminals. Bowser and son may be ready to double-cross Don Wario and Waluigi, but that Bob-omb peering around the corner--and the one in Waluigi's hand--at least implies that this won't be a simple grab and dash.

Who knew that Super Mario Bros. could be so seedy?
