Dizzy - Yenra Picture Wiki
Dizzy was abandoned by her mother Justice, and found as an infant roughly three years before the events in Guilty Gear X, by a couple.
However, the other villagers became afraid since Dizzy appeared to age from being an infant to her late teens in three years. This was compounded when she discovered, that she now had wings and a tail.
Dizzy was now identified as a Gear—essentially, a living weapon of mass destruction, and a hundred-year war against Gears had just ended five years ago. Dizzy's foster parents hid her in a grove in the woods, but she was soon discovered and subjected to abuse at the hands of her captors.
She quickly escaped, however, and the government issued a 500,000 World-Dollar bounty for her death. She was later taken in by Johnny and May, joining the Jellyfish Pirates
