There were only a few gods left that he could not defeat: Zeus, the King of Gods, Hades, the God of the Underground Ruling the Dead, Kratos, the God of War, and Izanami, the God of Death. In order not to be defeated, the remaining Gods go to Mount Olympus, where the Gods live.
Zeus does not intend to join the war and wonders what Ken can do against the forces of time.
Hades respects Ken's powers, but believes his death power can overcome Ken's time powers.
Kratos, however, is willing to join the fight and plans to use his own combat abilities against Ken's time forces. Izanami, on the other hand, is considering using her own death powers against Ken's forces.
While waiting for the other Gods' alliances to be completed, Ken enters the room where time passes slowly and continues to develop his powers. By foreseeing future events, he predicts what other gods might do and plans to respond.
Ken breaks through space and enters the Realm of Gods. He sees a huge mountain in front of him. He speeds up and enters there in a few seconds. He sees the Welcome to Olympus sign at the entrance of the mountain. He quickly climbs to the top of the mountain and sees Zeus and the other Gods.
Zeus gets up from his seat and moves towards Ken. Ken anticipated Zeus' attack and slowed down his time and moved. Ken slowed down time and threw Time Rays against Zeus, who attacked with his lightning powers. While dodging Zeus' attacks, Ken also planned to evade Zeus by slowing down time even further and bending Zeus' movements.
During this battle, Ken was making full use of his time powers and was able to anticipate and counter Zeus' attacks thanks to his foresight ability. However, Zeus used his own powers to make the lightning bigger and attack Ken.
Ken continued to counter Zeus' attacks as he tried to slow down time and avoid it. In this battle, Ken's foresight and time powers gave him a huge advantage against Zeus' lightning powers.
However, Zeus, as the king of the gods, was a powerful god and managed to resist Ken's time powers. Ken transfers all time energy to the Sword of the Time God and the second stage of the sword is unlocked.
Ken accelerates himself and at lightning speed his sword slices Zeus in half and throws him back to his seat. When Hades sees Zeus dead, he goes crazy and summons the Sword of Hell from under the ground.
