Bonnie grew up in the casino nights zone; her life wasn't ideal. Loud traffic jams, Mobian's yelling, Bright lights, it was an everyday thing for that stuff. It was annoying, but one thing Bonnie had was her family. People who love each other, something you could never lose, right?
That all changed. As Eggman was taking over the world, chaos rose everywhere. Things got 10x worse when Eggman blew up a third of the Casino Nights zone. Bonnie happened to live in said third, and things got bad. After being unconscious, Bonnie soon realized that she was the only one of her family to survive. Her home and family were stripped right from her. All because of Eggman.
She vowed to get revenge after such a tragic incident. So Bonnie took a pickaxe and headed straight to one of Eggman's bases the following week. She was going to kill him for what he did. While trying to wave around security. She was caught by an onslaught of robots that took her straight to the man Himself.
Quick interrogation revealed her plans, and Eggman realized something: her anger and determination...So instead of ending her life right there for intrusion, He strikes a deal.
A) Join his team and get something big in return
or B) She would be Roboticized
She feared the idea of even working for him, he took everything from her. But getting turned into a robot for revenge? worse. So, being cornered, she accepted the offer.
But what's the catch?
Eggman saw potential in her for many things, so. He did an experiment on her; he needed something to fight back the blue buzzkill after they saved the world. So he took one of SONIC'S quills and put it in her arm. Altering her genetics successfully, he had something to fight back Sonic and his friends. A hedgehog that's capable of moving at the speed of light and manipulating water.
It was sealed.
He had something to fight back Sonic and His friends...but would that really be the case? Especially with the telekinetic one?
