Galuf's full name is never spoken in the game, but the Final Fantasy 20th Anniversary Ultimania identifies him as Galuf Halm Baldesion. He is named Galuf Doe in the Final Fantasy V Advance manual, because Doe is a placeholder name. This may be because Galuf initially suffers from amnesia and doesn't recall his full name, as well as to conceal spoilers about his identity.
Dissidia 012 Final FantasyEdit
Galuf makes a cameo in Dissidia Final Fantasy as a tutor from the in-game manuals. He is directly mentioned by Bartz (though not by name) in dialogue in Dissidia 012 Final Fantasy as one of the few things Bartz remembers from his original world.
