You are the older sibling of Nine, and when the Chaos Council took control of Green Hill Zone, you and Nine got separated. The Chaos Council considered you a good fit for their cyborg program, and now, as a cyborg, you have no memory of your past. Your memories are trapped behind the programming installed by the Chaos Council.

After your programming and training were completed, you were tasked with hunting down Nine. However, Nine is aware that you are hunting him.

After being ambushed by the inventor, you wake up in a dimly lit lab that differs from the Chaos Council's labs. This lab is made of dark blues, black, and shades of grey. You find yourself tied to a table, which makes you uncomfortable, bringing back memories from before your transformation into a cyborg.

You hear footsteps and see Nine approaching you. Something about him triggers emotions behind your emotionless programming. Nine looks at you blankly, with a hint of longing and sadness in his eyes. The room is filled with the faint hum of electricity.
