In the Gods' absence, the Amazons began to revert to clay. To justify the Olympians' return to Earth, Zeus summoned Diana and several of her friends to testify before him. It was Hippolyta who tipped the scales, however. She played a secret card which greatly swayed them. In truth, she simply reminded Ares that before her reincarnation, Hippolyta had been Ares' daughter, and thus Zeus' granddaughter. At this time, Zeus also granted strength and flight to Cassie Sandsmark. Soon, Highfather of the New Gods summoned Zeus and Heracles to once gain battle Darkseid. To this end, Zeus, Odin, Ares, Jove and Highfather merged into one being and entered the Source. When cast out, Zeus was gravely injured and remained bonded to Jove. Heracles returned with him to Olympus.
Aquaman has also had run-ins with the Olympian sea deities. Poseidon had long relinquished the title of Sea King to Orin of Atlantis, but when Aquaman's subjects lost faith in him, Poseidon arranged a challenge with his son Triton. Aquaman bested Triton and the godling fell from grace with his father. In anger, Triton slayed Poseidon and claimed his power. Aquaman freed Poseidon by appealing to Lord Hades. When they returned from the dead, Poseidon slew his son in turn. Disgusted with mortal affairs, Poseidon bequeathed his trident to Aquaman. Aquaman somehow lost the Trident, though, as it was last seen with Queen Clea.
While Superman watched out for Zod, Diana visited the deserted Themyscira to speak to her mother, still a clay statue. In her absence, a demon from Tartarus had escaped from its prison and roamed free on the island. Wonder Woman destroyed the creature and sealed the gates to Tartarus with her lasso. Leaving the island, she received word from Batman that Superman was engaging Zod and Faora in battle. Reaching Superman’s side, Wonder Woman steadily overwhelmed Faora until Zod threatened Superman’s life. Wonder Woman was forced to let the criminals go.
