Don Dugo de Pato was a male anthropomorphic duck.
Don Dugo de Pato, a Spanish ancestor of Donald Duck (through the Coot side of the family), was a member of the Spanish Armada in the 1500s, and was in command of a Spanish treasure galleon sailing from the "New World" full of gold. Don, wanting to impress the king, had the ship plated in gold, however, this excess weight caused it to sink. Don escaped on a barrel, and noted the ship's position in his log.
Afterward, Don was cast off from the Armada, and moved to Scotland, where he married an ancestor of Scrooge McDuck. Soon afterward, Don met Caballero Carioca and Caballero Gonzalez. Together, the three called themselves the Three Caballeros, and, along with the goddess Xandra, who they had discovered trapped in a magical atlas, traveled the world, defeating the evil of Lord Felldrake. Eventually, they met Felldrake in battle and managed to trap him in his staff using their magical amulets. What became of them afterward is unknown. Their descendants, Donald Duck, José Carioca, and Panchito Pistoles, would later take up the mantle of the Three Caballeros
