I hope you guys like this. This is sorta my first Sonic fanfic so please just correct ,e if I make any mistakes, especially with the information. Anyways, here's the story!

Disclaimer: I don't own Sonic or any of its characters, but I do own the OC

Dr. Eggman was bored. After his latest defeat, he had lost interest in attacking Sonic and his friends for the time being. His robot companions, Bokkun, and Shadow the Hedgehog lounged about the ship, not really caring either. Scanning through his grandfather's old computer files, he yawned. But then, something seemed to catch his eye.

"What's this?" he yelled out, causing his other companions to jump in surprise, all except Shadow.

"What is it doctor?" Decoe the robot asked, but Eggman ignored him. Scanning through the project files, he began to cackle.

"Perhaps the doctor needs some fresh air" Bocoe suggested and Decoe nodded.

"His pants are a bit too tight on him" Just as he said this, the doctor bonked them both on the head.

"I'm not crazy, you fools! Look!" he pointed at the large computer screen.

"Project: Onyx?" Bokkun inquired. At the mention of the name, Shadow's eyes widened.

=FLASHBACK=

A purple hedgehog stood by the window, gazing at the planet known as Earth. Her black shaded quills fell a little passed her shoulders, and black stripes were imprinted on the side of her arms and legs. She wore a dark grey top with red straps on the center, a dark grey skirt skirt and dark grey also wore red band on her wrists and upper arms. She held a thoughtful expression as she merely stared out the window. Shadow approached her and placed a hand on her shoulder with the same thoughtful yet guarded expression.

"It's beautiful, isn't it?" she turned to him then back out the window.

"Yes, it is. Do you think we will be able to go there one day?" Gently wrapping his arms around her waist into a hug, Shadow replied,

"One day, Onyx. I promise, you will be able to feel the ground at your feet, and see the sky above your head."

"Will you be there by my side, Shadow?"

"I will" the female hedgehog turned to face him.

"Promise?"

"I promise"

=END OF FLASHBACK=

"Onyx" Shadow gasped.

"It says that this creature was sealed off as Shadow had been, and can only be activated by the use of a special gem." Eggman explained. The others began to sink in the information, and Shadow stood there, staring blankly at the screen.

'This Onyx, she's still alive?'

I hope it was alright. Anyways, please review!
