Was gonna throw this into a doodle dump but it's better on it's own.
While anyone can have a Tomo, the main one is given to Shadow! He is not too thrilled by it, but as a gift from the best lady ever, he can't deny. Tomo just wants to make Shadow happy! And is finding that a lot harder than expected. He will still do his best!
Tomos are programmed to be as "real" as possible! So they can react to different responses and respond when given various meals.
Note for this AU: Sonic doesn't exist in this world and Eggman isn't exactly an evil doctor. More of a mad toy maker that wants to take over the world using his gadgets! But he keeps getting distracted with all the cute Tomos he makes!
I am happily taking Tomo requests for anyone who wants to play with ideas! How would your OC react to owning a Tomo? Dress them up? Take them on adventures! https://forms.gle/kK1B95aoQ3HMFLGt8
