Final Fantasy isn't usually praised for racial diversity amongst it's main cast of characters, see Final Fantasy XV, but when controversial dark skinned characters like Sazh and Barret are created and thrust upon the nitpicking fanbase, heads are surely bound to turn. There has been many black characters throughout Final Fantasy's history but you could only count them on one hand at one point.
"Since Final Fantasy VII diversity has gradually crept through the cracks and introduced darker palettes"
In 1997 Squaresoft introduced it's first official black character 'Barett Wallace' a no-nonsense, stereotypical and walking parody of actor Mr T and whilst definitely not the best representation, fans who look beyond physical appearances will know as the story progressed Barett came across as a strong, caring and lovable character who would risk his own life to overthrow a corrupt government and save the planet.
Luca (Final Fantasy IV: The After Years)
Luca first appeared as a npc in Final Fantasy IV. She's the aristocrat of the dwarves in an underworld kingdom and the child to King Giott. She appears several years later as playable character in Final Fantasy IV: The After years with a drastic change in appearance.
In The After Years Luca's shadow face is gone and she now has a drastically different design. At present Luca has dark brown skin, plump lips and a wide nose. In the game Luca claims she was "never a fan of dwarven fashion", which makes us wonder if the rest of the dwarvens are black under their shadow guises.
Leo Cristophe (Final Fantasy VI)
It's been often said that Barett wasn't the first black character to appear in the Final Fantasy series. In Final Fantasy 6, Leo's skin complexion is a subject of discussion as he is depicted as dark skinned in Yoshitaka Amano's art and in his menu picture, As well as having the features of a black person but his in-game sprite is very pale in comparison.
His sprite being light-colored could be due to the colour palette restrictions within the game's code. In the mobile version Leo's sprite has a darker skin complexion.
Baret Wallace (Final Fantasy VII)

Barret was a character character designer Testsuya Noruma has wished to implement into the Final Fantasy series for quite some time but it wasn't until FFVII that this actually came to fruition.
