To celebrate the release of Sonic Forces, I created art of my Sonic OC based on the artwork from the Sonic Channel site!
(You can see what I'm referring to here: http://sonic.sega.jp/SonicChannel/character/sonic.html)

I’ve had Fluffy since I was 9 years old, so I guess she’s the oldest OC I have (or fan character if you want to be technical). Some aspects of her design have changed a bit since she was first created, but her general look has been mostly the same.
