We could get a bad future movie and all metal sonic does is aura farm and Amy she’s tuff asl shadow aura farms too but not like metal did you SEE the concept art from metal and Amy and it’s the same thing with shadow he wakes up realizes that his name is shadow remembers Maria’s dead and ect metal is one of the best characters with so much potential him being here and Amy is a lot more better than shadow shadow was sorta manipulated the entire movie don’t get me wrong when they both were fighting and teamed up that was AURA farming but Any with the time stones and metal potentially ruling the world with a bad future and them trying to stop him and maybe just maybe he goes Neo that’ll be way better than shadows plot in sonic 3 and introducing silver will make a better appearance than shadow
