Pirateman is an anthropomorphic mango piratethat debuted in the 1959 February issue of Wikia Heroes
Pirateman is an anthropomorphic mango pirate... He did some things once... I guess he became a pirate at some point. Maybe he likes Alestorm? his moustache is gray... maybe he's been at this a while.
While Pirateman himself doesn't make an appearance, his son, Captain Limon, does. Appearing during the Seafaring Saga trilogy, Limon assaults Koopa's Ship but gets defeated. This reveals that Pirateman does exist, or has existed in the Rulers of Wiki continuity.
