Flan Azabache uses higher level magic attacks, but is not difficult unless Oversouled. Having Reflect or elemental resistant equipment helps when facing it in Oversoul, and having several recovery items on hand helps to deal with its Demi spell. Absorb is nothing to worry about.
When recruited, Flan Azabache comes with Magic Up, Flare, Curaga and Life Preserver learned. It is advised to have it fight Humbaba in the Fiend Arena to learn Ltg./Water Eater, Total Limit Break and Ultima, becoming a force to be reckoned with. It can learn an additional Fire/Ice Eater from an enemy that casts fire or ice spells, e.g. the Djose Outlaws team of the Fiend Arena.
You wish to hear an old man's tale? Many years past, in the dark of night came a great flash of light. The blood of my people flowed like water, and the glow of the pyreflies blinded us all. It was like millions of stars falling from the sky. When day broke, I found myself in this form.
Let's skip forward a thousand years, hmm? Yevon preached about the horrors of Sin and the imperfection of humanity, and slowly grew in power. But I refused to let Yevon dictate how we should live our lives. So I began a movement against him.
We were but a small group, and Yevon persecuted us relentlessly. We were declared heretics and sentenced to exile in Baaj, but we would not even make it there. Yevon's followers, in accordance with his teachings, sent us to the Farplane in his name. Our remains turned into pyreflies, lighting up the night. Yet I resisted, choosing to become a fiend. Even the great Yevon has a dark side to his story. My mission is to make sure that part of his legacy is not forgotten.
But enough of such stories. My time has long since passed. Ironic, no? One of Yevon's own summoners bringing its long history to an end. I was murdered by a summoner, and sent on my way to the Farplane all those years ago. I have resisted the journey for a thousand years, but now I believe the time has finally come.
One notable Flan Azabache was created from the spirit of a man who lived 200 years ago. Part of a group against the newly established Yevon Order, this man met his end against a summoner and remained a fiend while his allies departed to the the Farplane. Brought to the Calm Lands by Yuna and Shinra, Flan Azabache tells them of the countless people who died whose names were never recorded in the history before fading away to be the light within the darkness.
Flan is an open pastry or sponge cake containing a sweet or savory filling. A typical flan of this sort is round, with shortcrust pastry, usually coated with sweet syrup. It is similar to a custard tart or a South African melktert.
Negro Azabache means "jet black" in Spanish.
