Dimension Iapetos was the second Titan to be released from Tartarus. He is a Titan with the ability to manipulate dimensional space.
Iapetus is the son of Uranus and Gaia, and the husband of his sister Themis. He is the father of the Titans Atlas (titan),Prometheus, Epimetheus, and the lesser known Menoetius. He is one of the Titans who helped Kronos defeat Uranus. The Titans fought with their king and brother during the Titanomachy, but were defeated and imprisoned in Tartarus for challenging Zeus.
He was forced to helplessly witness Zeus punished his two sons:Atlas was sentenced by him to hold up the sky for all eternity, while Prometheus, who stole fire from Olympus to give to mankind (and from there developed all man’s technology) was punished by being chained to a mountain where an eagle constantly devoured his liver, an eternal torment for the immortal Prometheus.
War against Gold Saints
Iapetos was the second Titan awakened at the prompting of Pontos, appearing in Jamir to kill Aiolia, Mu and Taurus Aldebaran who were there to repair the Leo Cloth. Mu decided to fight alone against him; at first, the Gold Saint seemed to have advantage against the Titan, who invoked a Hecatonchires to fight for him. Iapetos also succeeds in demolishing the Crystal Wall and attacking Mu several times. As he prepared to use his most terrible attack, Kronos intervened and ordered him back, interrupting combat.
