Emperor Ali Swan is an anthropomorphic swan.
The middle-aged Ali Swan is the Emperor of the small foreign country of Alistan. Rather than an idle nobleman, Ali Swan is also a skilled businessman who serves as CEO of Alistan's most thriving industry, the culture and exportation of a special variety of avocados. Tricky if not outright villainous, Swan once sent Scrooge McDuck an elephant as a "gift", knowing full well that the capricious animal could only be fed with great quanitties of Swan's own avocados.
Behind the scenes
Ali Swan only ever appeared in The Costly Cat.
