The Titans were the eldest of the three races born to Gaea (also spelled Gaia) the Earth and Ouranos the Sky, before the Hekatonkheires (Cottus, Gyges, and Briares) and the Elder Cyclopes (Arges, Brontes, and Steropes). All were detested by their father, but he detested the six younger children so much (mainly for their ugliness) that he imprisoned them in the terrifying abyss of Tartarus, which was itself deep within the Earth. Enraged at Ouranos and his actions, Gaea then gathered her remaining twelve children, the Titans, to free their brothers and overthrow their arrogant and sadistic father. Kronos was the boldest, as well as the most ruthless and devious and cruelest of the siblings (even though he was the youngest) and, initially, only he would agree to help his mother. While growing up, Kronos would frequently resort to dirty fighting tactics while wrestling his elder brothers, earning his infamous nickname "The Crooked One." Furthermore, as the youngest of the twelve Titans, Kronos was initially ignored by his parents (who even had trouble recalling his name), which inspired the young Titan to prove himself as superior to his elder brothers, in any possible way. This is also what inspired him to sadistically murder his father. Though the youngest, Kronos proved himself as a natural leader, and was able to convince all of his Titan brothers (except for Oceanus) to aid him in their father's murder. Kronos' sisters Theia, Tethys, Themis, Phoebe, Mnemosyne, and Rhea also refused to participate.
