Nova

Nova Chaos is the Viottis daughter of Gaia and the Greeks. She and Gaia are the only known Viotti in existence. Her actual birth year is unknown, albeit she was awoken for the first time by the Greeks in 776 BC.

Viotti only have one parent, and it is not genetic. They also technically aren't birthed either. They are 'buried' until someone finds them and brings them into existence. Gaia had been dug up long before Nova was. Their parent claims them at the burial site. The Greeks had found her, but they had claimed that the ancient Viottis, Gaia, was her mother. So, they reburied her, in hopes that Gaia would find her.

Unfortunately for them, 3 other civilizations, Rome, Egypt, and Mesopotamia, had found her, all claiming to be the parent. The Greeks had fought for her back, creating a war between the four. Eventually, Greece had gotten her back and she stayed with them until Alexander the Great had died in 323 BC, when an alien, who called himself Sir Reginald Hargreeves, abducted her and trained her.

He made her become the most advanced being in the universe, with the ability to absorb other's pain. He then left her uncharged, or in an unconscious state, for 2,685 years. And then a phenomenon took place, which unknowingly sent her path for life downhill.
