The Cloud of Darkness is the antagonist and final boss of the game's final story Rhapsodies of Vana'diel. Also known as the Void, the residents of Tartarus know it as the Cloud of Darkness, and that it is a primordial being that resides in the space between worlds. It consumes light and darkness, ceasing all life in its path while leaving a lifeless realm called Escha in its wake.
The Cloud of Darkness began to seep into Vana'diel when Promathia's destruction weakened the winds of time, despite numerous adversaries that maintained the balance of light and darkness. In one future, the Cloud of Darkness would fully appear in Vana'diel once all five Mothercrystals have been shattered from the corrosion caused by it. The future version of the adventurer attempts to defeat the Cloud of Darkness by expelling his/her darkness to become a god, but the plan fails and his/her counterpart is turn into the cloud's thrall Volto Oscuro.
Volto Oscuro acts to invoke the Cloud's manifestation prematurely in present-day Vana'diel, before being freed by Sempurne. Though the adventurer and his/her counterpart restore the winds of time before rejoining, the Cloud enters the Reisenjima Mothercrystal to gather its strength with Iroha attempting to hold it off. The exposure to Phoenix's power consolidates the Cloud of Darkness into physical form so it can be destroyed. After the battle, the Cloud of Darkness implodes with only its mask remaining before it shatters.
The Cloud of Darkness appears as the antagonist of the Crystal Tower story arc, and the final boss the World of Darkness raid. She is a powerful Voidsent who made a pact with Xande to be brought into Eorzea.
Among the antagonists, the Cloud of Darkness plays a small role in the storyline. Along with Kefka, Kuja, and Exdeath, it desires to plunge the world into the Void and destroy everything. Under Kefka's instruction, it kidnaps Terra to use as a tool for their plan, and confronts the Onion Knight with his childish fears and bravado. After Terra is rescued and the Onion Knight claims his Crystal, the Cloud of Darkness takes a minor role.
The Cloud of Darkness's alternate outfit colors its cape blue, while its EX Mode is colored a mixture of light green and dark green with a dull red for the legs.
The Cloud of Darkness reappears as a Warrior of Chaos in the prequel to Dissidia Final Fantasy alongside all the other characters from the original. It attacks Laguna, but is intrigued by his attitude towards serving Cosmos and fighting the Warriors of Chaos. Cloud of Darkness tells Laguna about the portal the manikins are using to cross over into World B from the Void to see what he does with this information, as seeking out the portal would be a suicide mission. The Cloud of Darkness's actions result in Laguna and other Warriors of Cosmos finding and closing the portal, and as punishment for its treachery, Kefka kills the Cloud of Darkness in the twelfth cycle, costing it its memories in the thirteenth.
The Cloud of Darkness's second alternate outfit gives it a white cape with white, blue and lavender body coverings. Its EX Mode in its original alternate outfit is changed to an orange and blue form resembling its NES battle sprite.
When the balance between light and dark is lost, a perfect void will be born that goes beyond all else and puts a stop to time's march. This being of pure darkness desires such nothingness above all else.
