With nearly all of the Chaos Emeralds in hand thanks to Rouge and Shadow, Eggman announces his intention to conquer the world, using the Emeralds to fire a laser cannon to intimidate the government. As Sonic and his allies try to grapple with the threat looming on them, Chris finds himself under Shadow's watch as the Ultimate Lifeform reflects on his past, along with a promise he made to a friend.
