Duwingo was a male Yaka slave to Maka Jeth. He served on Maka's freighter, Maka's Delight. As a side-effect of illegal genetics done to his species, Duwingo appeared to be dumb, and also had a knack for terrible jokes. Another part of his "condition", he spoke words with the letter O longer than others without. He and Maka captured the renegade Jedi, Nathaniel Kenobi's wife, Abigaile Jade Kenobi, and her child Abigail Kenobi, on the planet Tatooine.
