King (OOO)

The First Kamen Rider OOO was Eiji Hino's predecessor who orchestrated the creation of the Greeed so that he would achieve godhood. He is also an ancestor to Kosei Kougami.

Personality
According to the Kamen Rider OOO novel, the first OOO was similar to his descendent but evil. He was a power-hungry greedy king that had a soul of desire (欲望の魂, Yokubō no Tamashī) who desired to become a god and in order to achieve his goal, he had four alchemists create the Core Medals, which manifested themselves as the Greeed, and the OOO Driver in order to harness the power of the Medals. He went as far as to betray his own allies in order to obtain what he wanted; first by turning the alchemists into Cell Medals and then taking his partner Ankh's Core Medals by force. Similar to his descendant Kosei Kougami, he also has a habit of shouting "Happy Birthday" as seen when he took the Greeeds' Core Medal during their birth.

Abilities
The King possessed the same equipment and abilities as Eiji, the only difference was that his O Scanner had a deeper voice and he had a specialized set of Core Medals that were much more powerful. Unlike Eiji, who possessed no selfish desires, the king's self centered desires made him descend further into insanity with each transformation.

History
The First Kamen Rider OOO was a greedy king of a mysterious lost European civilization, who wanted power more than anything else. Having Gara and three other alchemists create life through the Core Medals which became the Greeed, beings of living desire. After he witnesses the birth of the Greeeds, he says “Happy Birthday!” as he takes their Core Medals. Ankh joins up with the other Greeeds and agrees to take down the King together, in order to retrieve their Core Medals.

The King was insanely strong and controlled a large portion of Europe. He used the combos very efficiently; with Gatakiriba, he cloned himself and destroyed neighboring countries and their armies. He used Tajador’s flight to his advantage and burned down villages that tried to oppose him. With Latoratah’s speed, he infiltrated enemy camps and strikes quickly. He used Sagohzo and Shauta to cause earthquakes and tsunamis to take down the Spanish Armada. The Greeeds finally managed to get their Core Medals back, but even when they were in their full form they couldn’t defeat the King.

In order to defeat him, they resorted to using Yummies created from the King’s greed. Uva, Kazari and Mezool creates the Cockroach, Lion and Whale Yummies, they were almost as strong as a full form Greeed because of the King’s strong greed.

But none of that was enough as Ankh reveals that he was working with the King all along, but the King betrays Ankh and leads up to all of them being sealed and took thier cores by force. He scanned all thirty Core Medal types at once in an attempt to gain their power through the OOO Scanner, which he thought could fulfill his desire to become a living god. However, this became his undoing.

The power was too great for him to handle and the First OOO turned into the stone coffin, and the four Greeed: Uva, Kazari, Gamel, Mezool, along with Ankh's right forearm became sealed in. The OOO Driver, the very thing that the greedy king sought to gain power from, became the lock of the coffin itself.
