The World is Gray (Sonic Fan Fiction)

Monochrome is an emotionless scientist who only cares about his research (which is about Extra-Sensory Perception). He hates colors and anyone that smiles because of his troubled past, but the present attempts to change him. Heartless Monochrome will encounter several people who will try to help him smile. Will they be successful, or will he destroy life and its happiness? You will only be able to find out if you proceed into the darkness of Monochrome's heart.

I wrote this one when I was twelve. Be wary that it might not have the greatest development.
