It was originally called https://en.wikipedia.org/wiki/El_Mercenario btw (even I know that much Spanish ;) ). Strangely, Wikipedia categorizes it as sci-fi. You could call it medieval sci-fi, I guess.

If we're expanding out a bit, there's always https://en.wikipedia.org/wiki/Kalim%C3%A1n

Which comes with this fun piece of history:

The comic was so popular that it was one of the few Mexican comics consistently sold in the United States, mostly in areas with a large Latin American population. Since the character The Incredible Hulk used the subtitle "El Hombre Increible" for Latin American editions and was first published in 1962, Marvel Comics sued Promotora K for using "El Hombre Increible" in Kalimán's comic title. After several months, the court ruled in favor of Promotora K with the reasoning that Marvel did not use the subtitle "El Hombre Increible" until 1968, years after Kalimán was sold in the United States. As a result of this ruling, Marvel Comics had to pay royalties to Promotora K to legally use "El Hombre Increible" in the Hulk's titles. After the decision was made, Promotora K made several Kalimán covers featuring parodies of popular Fantastic Four characters threatening Kalimán.

Kalimán is so incredible that the Hulk had to pay him royalties.
