Helios is the Greek Titan of the sun, responsible for sunrise and sunset by riding his flaming chariots across the skies. He is the son of Hyperion (the Titan of light) and Theia (the Titaness of the sky). His siblings are Selene (the Titaness of the moon) and Eos (the Titan of dawn).

Helios has two children: Aigle and Phaeton. The latter appears in one of the stories that was used to explain the origin of colored skin and the appearance of African deserts. He had relationships with Oceanids and water nymphs.
