Kurenai no Buta
The plot revolves around an Italian World War I ex-fighter ace, now living as a freelance bounty hunter chasing "air pirates" in the Adriatic Sea. However, an unusual curse has transformed him into an anthropomorphic pig. Once called Marco Pagot (Marco Rossolini in the American version), he is now known to the world as "Porco Rosso", Italian for "Red Pig" or "Red Pork". (Source: Wikipedia)
