Dark Lightning Koios is the third Titan Pontos released from Tartarus and Phoebe’s consort.
Koios is a god of calm mind and great wisdom, perhaps the most intelligent of the Titans and whose ability to “understand everything” by analyzing earned him the title of “Him that everything has discovered / understood”. Koios also has a high value of honor in combat, making it among the other gods denote. His simple smile, keeps a great friendship and bond with Hyperion and cares for his wife Phoebe .
He fought against the Olympians in Titanomachy, siding with his brother Kronos. Koios created the Keraunos, the Thunder Bolt, a force that could kill even the gods themselves, but was so powerful and destructive that Koios decided to hide it forever by placing the object within his own memories. However, his sister, the Titaness Mnemosyne, found the Keraunos’s hiding place and gave it to Zeus. With such power, the king of the Olympians managed to defeat his father and the other Titans. Along with the others, Koios was sentenced to Tartarus.
