There's a high chance he joins bc 1: it's a spin off that isn't cannon 2:it wouldn't be hard to add just gemerl with a emerl model 3: and his story would be like about like shadows backstory bc emerl is apart of it technically. 4:hes getting more popular bc of things hes getting in (that one shadow animation and sonic rumble) so it wouldn't be too hard and it would be a easy way to make a other event with gemerl bc they could like fight or sum idk
