from a machine to a new world

while Eggman was make a machine to beat sonic once and for all he ended up misunderstanding his own instructions and that leads to putting everyone even sonic and his friends allie/rival shadow the hedgehog,to also follow along and there they meet a new friend/sonic's old friend.but for shadow he gains feeling for his'rival' but will have to deal with Amy to get to his heart.will they find a way back with a better future or will things stay the same(hope it was good cause idk what to put here rlly)
