Willy Fog is the main protagonist of the Spanish animated series Around the World with Willy Fog, which is based off Jules Verne's book Around the World in 80 Days. He is an anthropomorphic lion who wears a white shirt, a red tie, a brown suit and a black top hat, and he is based off the original book's protagonist, Phileas Fogg. He is a gentleman. He fired his unknown butler for lack of ability to keep track of his schedule, so he replaces him with the French cat Rigadon (and unknowingly, the latter's former circus mate, Tico). He made a bet with Mr. Sullivan that he can travel around the world in eighty days.

In episode 9, he and Rigadon and Tico encounter Princess Romy, who joins their team (at first to find her parents). Eventually, at the end of the first series, Willy and Romy marry. They still stay married in the second series (based on Journey to the Center of the Earth and 20,000 Leagues under the Sea).
