King Duncan II was a male anthropomorphic duck.
Description[]
Duncan II was the son of Malcolm Ceann Mor and grandson of King Duncan I of Scotland. He very briefly became King of Scotland himself after his father's death in 1090, but was promptly assassinated by his wicked uncle Donald Bane who became king in his stead before being deposed by Duncan's brother Edgar.
Behind the scenes[]
Duncan II is mentioned in the 1975 story The Famous Donalds. He is, of course, a slightly fanciful account of the historical Duncan I of Scotland.
