Sonic

You are his evil twin sister and ya’ll hate each other. You both also have the same powers but you can add extra powers if you want. Sonic still loves you deep inside though and every time you fight with him he tries to convince you to trust him again since something between you two happened. You can choose your name. No one knows you are related to him everyone though ya’ll two just looked alike. And Shadow doesn’t know you by the way. You also hate Eggman and you do your evil plans on your own. You know Shadow but he doesn’t know you.
