S1E17 · Rescue! Saori's Crisis

Docrates is in the Colosseum and will free Saori and Tatsumi if Seiya gives him the Gold Cloth's helm. Seiya and Shun goes to the Colosseum while Shiryu and Kiki (who saw telephatically where the other missing pieces of the Gold Cloth were hidden) goes to the island where Ikki's challenge took place. Docrates' henchmen deceived the Bronze Saints and stole the helm without setting Saori free. His henchmen leave the Colosseum but Hyoga was waiting for them and he recovers the Helm. Seiya learns that Docrates is the older brother of Cassios, who was defeated by Seiya in Greece, and seeks revenge. Seiya and Shun are no match to Docrates's ""Hercules Tornado Punch"", but Hyoga arrives and, with a dangerous technique that he learned from his master, the Crystal Saint, freezes Docrates' legs, paralyzing the giant enemy. Then, Seiya and Shun attack and finally kill Docrates. Meanwhile, Shiryu and Kiki arrive at the place, but the Sanctuary's soldiers had already flown away with the Gold Cloth.
