  Poseidon, first king of Atlantis.

• Thousands of years before it sank beneath the waves, Atlantis was ruled by sorcerer kings. During these times, Atlantis (along with most of the ancient world) found itself under attack by extra dimensional beings called the Old Ones. The Old Ones nearly destroyed humanity as they prepared the way for Ichthultu, the most powerful of them all. Channeling almost all of the ambient mystical energy on earth, King Poseidon forged a Trident capable of banishing the Old Ones. However, the price was high as the same mystic energy Poseidon used to defeat the Old Ones also powered the spells that prevented Atlantis from falling beneath the ocean. Having saved the world, the king doomed the Atlantean people to a life beneath the sea. (JL: The Terror Beyond)

Hades tricked Hippolyta into opening the gates of Olympus for the Titans, resulting in a battle so fierce the Muses still sing of it thousands of years later. The Gods fought back, and eventually prevailed. As punishment for his treachery, Zeus cast Hades into the pit of Tartarus, where he would rule over the dead for all eternity.
