An official Final Fantasy comic was close to releasing in the 90s, but was cancelled at the last minute
Here's an interesting tidbit of information for you. Back before the Japanese release of Final Fantasy IV, Square-Enix (then Squaresoft) had given the greenlight to a Final Fantasy comic series that would release in North America. Unfortunately, that project ended up getting cancelled before it could see the light of day.
Writer Kurt Busiek revealed that the comic would have featured interior art by Dell Barras, letters by John Costanza, covers by Mike Mignola, and Hollywood Comics would be publishing. Multiple scripts written and an issue and a half's worth of drawings had been done before the plug was pulled. Characters were loosely based on the North American version of Final Fantasy II, and some of the Japanese names would have been "Americanized."
Unfortunately, what we see above is pretty much all that's left of the comic. As to why it was cancelled so late into development, that remains a mystery.
