The Celestial Genesis Era is the first known era, covering the events of Aquarion: The Movie (and the two OVAs that it was adapted from). This era (along with the entire planet) was destroyed by the Solar Aquarion.

This era is before the events of Genesis of Aquarion, however it affected the events in Genesis of Aquarion. In this world, Apollo lived in a forest by himself until one day, Silvia de Alisia and Reika fight the Shadow Angels in the Assault Aquarion, destroying part of the forest he lives in. In this world, Sirius de Alisia was killed by the Shadow Angels, and Reika's reincarnation, Scorpius, is still in the Book of Holy Genesis.

At the end of this era, the world was destroyed, but the events affected another world.
