The fight between Sonic and Dark Oak starts. Sonic directly attacks Dark Oak, but he instantly disappears: it was a hologram. Outside the fortress, a Metarex armada, led by Red Pine, is approaching. Surprisingly, the Red Pine army begins to attack their own fortress, while there still are Metarex inside. Shadow, Rouge, and Chris are transported, via Chaos Control, inside the Crimson Egg. Chris finds a way to steal the emeralds found by Eggman and flees away by using one of Eggman's mini-ships. Shadow follows him and he stops him. The 7 Chaos Emeralds are put together, transforming Sonic and Shadow into their super forms. Super Sonic and Super Shadow engage into a fight inside the fortress. At the same moment, a gravitational field is activated inside the fortress and it starts to destroy itself from the inside. The Metarex armada is destroyed, Super Shadow sends the Crimson Egg away with Chaos Control and the Blue Typhoon escapes with the power of the Master Emerald. However, during the event, the 7 Chaos Emeralds disappeared.
