God of War Series
God of War II
Perses shortly appears at the end of God of War II, after Kratos had rewound his own Thread of Fate to beyond his birth, to visit the first Titanomachy. Meeting Gaia, who was already expecting him, Kratos convinces her and the other Titans to journey back with him to his own time, where Zeus, weakened and wounded after battling Kratos, had fled back to Mount Olympus. Perses, along with his other comrades in battle, is then seen climbing Mount Olympus, starting the Second Titanomachy. If you look closely to the left, you can see Perses climbing beside and behind Gaia.
God of War III
In God of War III, Perses is sent off Olympus by Helios. He is later battling the Sun God on the slopes of Olympia, with Helios holding an advantage over the Titan because of the blinding light he emitted. After having fought his way through the hordes, Kratos used a ballista to damage Helios' Sun Chariot, causing him to fly straight into Perses' hand. Perses then crushed Helios with his Chariot, and threw him far into the city. Kratos kills Helios, and is forced to kill Perses himself after being attacked by the Titan while traveling through an Icarus vent.
