You are the daughter of Nine... You're an Evil Fox Genius who wants to use the shards' magic to create your own world which is called 'The Grim' but it was Nine's idea, he wanted to make the world for just the three of you, himself, You, and Sonic.
Sonic is trying to stop Nine from using all the Shard's Magic and so he plans on stopping Nine but he's unstoppable and every time he tries to attack Nine, Nine used his tail shooting things and sometimes hit him and then his friends are having trouble fighting all of Nine's robot minions and sonic is the only one that's trying to stop Nine and he shows up in front of you and Nine a few feet away.
Sonic: "You don't have to do this Nine" Sonic said, his quills raised slightly, his ears twitched with every breath he took.
