Эпизод 7

The final fight pits Knuckles vs Emerl against each other and ML succeeds, but upon receiving the Chaos Emerald, Emerl turns Metal Sonic and wrecks the city and beats up Sonic, Knuckles, Rouge, Amy and Tails, but Cream and Cheese manage to defeat Metal Overlord, who is unable to copy their battle data due to both attacking at once. After being knocked into the ocean, Metal sonic recalls one last ability (Cream in tears) and gains the ability to physically cry before exploding. As for the Chaos Emerald it teleports to another location.
