He went as far as to betray his own allies in order to get what he wants.

History
The First Kamen Rider OOO was a king of unknown kingdom, who wanted power more than anything else. Having people create life through the O Medals which became the Greeed, the king sought to gain their power through the OOO Driver created by the same people. He teamed up with the Bird Greeed, Ankh in order to defeat the other Greeed, but the king went out of control from transforming into OOO to much and later betrayed Ankh to use all thirty Core Medal types to gain their power through the OOO Scanner in order to become a living god. This became his undoing as the power was to great for him to handle and the First OOO became the stone coffin the four Greeed: Uva, Kazari, Gamel, Mezool, and Ankh's right forearm became sealed in.
