Greek Mythology: The Fall of the Titans (part 1)

 Zeus ...
Zeus grew up preparing to overthrow his father Cronus. Gaia gave a "poison" to Zeus when he was ready to finally go through to overthrow Cronus. Zeus slipped it into his drink and Cronus became very sick and regurgitated all of his 5 children first came the rock that he had swallowed and the children followed in reverse order Hestia being the last to be expelled becoming the first and the last born of the Olympians... (lol fun fact)...

Lol... its kinda hard to explain

Zeus then freed the rest of Gaia's "monster" children and in exchange that they would help his against the Titans but the Cyclops went even further in giving Zeus the gift of thunder bolts, Hades the Helm of Darkness (makes the wearer invisible), and Poseidon a Trident.
