The Lostbelt Olympians are the Greek Lostbelt of the Gods of Olympus and the major antagonists of Fate/Grand Order: Cosmos in the Lostbelt. They are the secondary antagonists of Atlantis and Olympus chapters, composed into the two-parted Greek Lostbelt chapters, and the core allies of Kirschtaria Wodime.


The Greek Lostbelt, also known as the Atlantis Losteblt, diverged in 12000 B.C. around the same time of Fate/Extella: The Umbral Star, where the Velber arrived in the Solar System and Sefar slaughtered the original God Concepts, the Twelve Pillars, beginning the decline of the Age of Gods. In this Lostbelt, the Olympians defeated the Velber and maintained the Age of Gods intact.

When Zeus decided to expand the Age of Gods to further their reign, Hephaestus, Hades, Athena, Apollo, Hestia, Ares opposed him and got destroyed in the resulting war. Zeus survived alongside Artemis, Poseidon (at the time still active), Demeter, Aphrodite and Hera, and continued to rule the world. They advanced their powers and technology to the point where they redefined the concepts of Gods and fully became machines, with powerful divine nanomachines being used as Authorities.

For instance, Hades was reconstructed into a nanomachine armor wore by Odysseus, who guarded the gate into Mount Olympus, now became a floating mountain attached to its Fantasy Tree named Atlas. Artemis took the form of becoming a gigantic satellite laser cannon with heavy destruction scale. Poseidon was reconstructed into a gigantic submarine similar to a whale.

Later, because of Caenis' interruption, Poseidon began losing his authority over the sea, and subsquently spawning new forces among it. He eventually became the guard of a black hole leading towards Mount Olympus. One of his core was later stripped by Francis Drake, rendering him into a machine with just a little sentience.

Currently, Nanomachine Hades vanished after the Chaldea crew defeated Odysseus with the sacrifice of Charlotte Cordette, Artemis was defeated and shot down by a sacrificial attack from Super Orion, and Poseidon was destroyed when the crew had destroyed its remaining cores, but with the price of Iason's sacrifice.
