Dr. Z reveals that the armor the Torvosaurus was wearing was the result of a stone that was on its head. Sophia reveals to the D-Team that her brother is Spartacus and that he was taken away by the Roman Army sent to her hometown of Trachia by Lucius Cornelius Sulla. The D-Team has a run-in with Foolscap of the Space Pirates who arrives to claim the Yellow Cosmos Stone after Gavro's failure. Foolscap unleashes a Shunosaurus upon them, followed by equipping it with the armor in its battle with Chomp. The Alpha Gang and Terry run afoul with the Roman military. Foolscap attacks Max and Rex again until realizing that the Yellow Cosmos Stone isn't with them. When Shunosaurus ends up occupied with the Roman Military, Majungasaurus was used to help obtain the Yellow Cosmos Stone from Sophia. The D-Team arrives and sends Chomp, Ace, and Paris into battle while Foolscap activates the armors for both his dinosaurs. With the new Move Cards taken from Dr. Z, the D-Team defeat the Majungasaurus and Shunosaurus, but Foolscap escapes. (Source: Wikipedia)
