The show opens with a fight involving a huge Metarex named Scarship and an armada of smaller ships. Scarship destroys every ship and he's assigned to a new mission: to destroy Sonic and Dr. Eggman. Inside the Blue Typhoon, everybody questions himself about Shadow's return. Aboard the Egg Carrier, Dr. Eggman finds out that Scarship is approaching and the battle engages. Eggman sends Shadow to destroy Scarship, but Shadow is unable to do the job. Rouge flees from the Egg Carrier, just before Starship sends a missile and seems to have destroyed it. Rouge informs the Blue Typhoon's crew of the situation and sends them images from the battle. Cosmo recognizes Scarship, it's the Metarex who destroyed her group's ship. Cosmo begs Tails to flee away, because she doesn't want to risk her friend's lives. However, Sonic and the others insist that they need to face Scarship. The battle starts and nobody gets the advantage. However, Sonic, Amy and Knuckles leave the ship unnoticed and they find a way to block Scarship's weapons. Scarship decide to destroy the Blue Typhoon by crashing into it. The Typhoon won't be able to get out of its way in time, but Shadow appears from nowhere and takes Scarship away. It appears that Eggman was able to escape from Scarship. Sonic and Shadow get inside Scarship and they destroy the engine room. However, Scarship won't ever surrender and it's about to self-destroy. Shadow is able to freeze time around it and Sonic defeats it with the Power Cannon. (thetvdb.com)
