He aided Kratos for a period of time the vicious beast known as the Hydra terrorized the Aegean Sea, until Kratos, guided by Athena, was called upon. Arriving upon a mess of shipwrecks, Kratos battled the various heads of the Hydra. During this feat, he was met by the great God Poseidon, who granted Kratos the gift of Poseidon's Rage. With this magical ability Kratos was able to cast a stream of lightning through his body into his enemies, destroying them or weakening them enough so that he may finish them off. This ability would also be of important use while battling against the Hydra King, the strongest and largest of the Hydra’s heads. After destroying the beast, the nightmare the Hydra had caused for many sailors in the Aegean Sea came to an end.Poseidon was also given a section devoted to him in Pandora's Temple. In this section, Kratos obtained Poseidon's Trident, granting him the ability to breathe underwater and dive. Atlantis' Destruction While Poseidon does not appear physically, the god manifests himself through one of his statues. Infuriated with Kratos for Atlantis' destruction, he vows he will never forget Kratos' actions, promising he would one day answer for them. Also, his personal army, his "children", the Tritons, appear as enemies. Following Kratos opening Pandora's box, Posidon was infected with the evils the box held, and thus slowly succumed to his own plague, anger. This corrupted him, causing him to side with his corrupted brother, and oppose Kratos. Kratos was forced to kill him. His death caused the sea's to be rendered out of control, and thus flooded most of Greece.
