Curiously, the image names of the Pirate Gunner on the 2015 LEGO Pirates website referred to him as Rummy. While he has several elements in common with the original Rummy minifigure (the brown tricorner hat, grey pants, and general design of his shirt) his eyepatch has switched sides, he's gained a mustache, and the main color of his shirt is now green rather than blue.
This is a pirate who is fond of gunpowder. But his hearing has suffered from all that canon noise, and now the Gunner is practically deaf. But sometimes, when the parrot won’t stop blathering, this is a good thing.
