Icon-oooThis article is about a villain in Kamen Rider OOO.

The Ancient King (古代王, Kodai Ō), or simply King (, Ō), is the overarching antagonist of Kamen Rider OOO. He is Kousei Kougami's ancestor who created the Greeed 800 years ago as the original Kamen Rider OOO (仮面ライダーオーズ, Kamen Raidā Ōzu). In the present day, he is revived and transforms into Ancient King Kamen Rider OOO (古代王仮面ライダーオーズ, Kodai Ō Kamen Raidā Ōzu),[1][2] or Ancient OOO (古代オーズ, Kodai Ōzu).[3][4]


OOO absorbs Medals

The Ancient King, as the original OOO, absorbs all the Core Medals.

The original 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. When he no longer needed the alchemists, the king turned them into Cell Medals, not knowing that Gara's consciousness is still intact. 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 Tajadol’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 created the Cockroach, Lion, and Whale Yummies, a group of Yummies who were almost as strong as a fully restored Greeed thanks to the King’s strong greed.

However, none of them were 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 their 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 was turned into a stone coffin, Uva, Kazari, Gamel, Mezool, along with Ankh's right arm were sealed. The OOO Driver, the very thing that the greedy king sought to gain power from, became the lock of the coffin.


10 years after the events of the main series, the Ancient King is resurrected by unknown reasons (implying that he regain back his body after Ankh unsealed the coffin at the beginning of the series), and by taking advantage of Dr Maki's lost Medals, he manages to revive the Greeed and plans to conquer the world again. At some point, he fights Eiji Hino and wins, and as Eiji is trying to protect a little girl, the King lands a devastating blow on him.

In an attempt to take Ankh's Core Medals, he sends Uva after him, but Uva fails and is defeated by a Goda-possessed Eiji. Disappointed by his underlings, the King absorbs all of their Core Medals and decides to take matters into his own hands. He swiftly gains the upper hand on Eiji and resolves to take his (Goda's) Core Medals as well. However, Ankh gets in the way and becomes absorbed instead. To the King's surprise, Ankh's consciousness is still active within his body, and the Greeed tosses Eiji the Purple Core Medals to allow the transformation into Putotyra Combo. Goda-Eiji then proceeds to use the Combo to finally destroy the King for good. The King's Medals would later be absorbed by Goda.

Other Events[]

Kamen Rider OOO: Final Stage[]

Greeed (King) Profile

The Ancient King assumes his Greeed form, resembling Eiji's

In the Final Stage, it is revealed that his soul was traveling in parallel worlds after his death. In order to regain his original power of OOO, he sealed every OOO in each parallel world and became the ruler of the World of Putotyra. He uses a gold medal to teleport Eiji Hino, the last OOO from the World of Tatoba, a.k.a. the main OOO world, to the World of Putotyra. King assumes the form of OOO PuToTyra Combo to gain the trust of Eiji, and reveals his true identity after gathering other Greeed. He battles Eiji in his Greeed form and gains an advantage until Ankh grabs the medals from him and the other Greeed. He is ultimately defeated by eight OOO after Eiji releases all the other OOO from the seal. [Kamen Rider OOO: Final Stage]

Kamen Rider Travelers Record[]

In this game, the Ancient King was revived by a scientist, but turned wild and rampaged, like when Eiji was possessed by the purple Core Medals. Thus, the King rebelled against his own creator. He serves as the main antagonist of the game.


According to the Kamen Rider OOO novel, the original OOO was similar to his descendant Kousei Kougami, being an eccentric ruler with little regard for consequences. In general, he was a power-hungry greedy king that had a "soul of desire" (欲望の魂, Yokubō no Tamashī), becoming more unhinged as he used OOO's powers. This caused the King to ultimately betray his own allies entirely; first by turning the alchemists into Cell Medals and then taking his partner Ankh's Core Medals by force. Similar to his descendant Kousei Kougami, he also has a habit of shouting "Happy Birthday" as seen when he took the Greeeds' Core Medals during their birth.


The King possessed the same standard equipment and abilities as Eiji, alongside the tenth Core Medal of each five set. Immensely selfish in nature, the King did not suffer the same drawbacks as Eiji when using OOO's powers, his greed empowering him greatly. The King's Tatoba Combo alone proved capable of facing all five completed Greeds with ease, using none of his finisher moves to defeat them. However, this selfishness ultimately became the King's undoing; his mind and body being consumed upon attempting to access OOO's full powers.

When he was revived in present day, he had new powers where he was capable to shoot energy blasts and spears. He wields his own sword along with the Medajaribur for energy slash attacks. After he absorbed all the Greeeds, he was able to utilize all of their powers.

As Tatoba Combo, OOO is armed with the Toraclaw gauntlets, and can transform his legs into Batta Legs to reach enemies that are out of his reach, such as ones that can fly. This Combo is also the most balanced in speed and power.

This Combo's Scanning Charge finisher is the Tatoba Kick (タトバキック, Tatoba Kikku), where after jumping high up through the Batta Legs, OOO descends with a drop kick through the three rings that are formed, which are in the primary colors of the Taka, Tora, and Batta Medals which surround him in auras depending on the Core Medals. When passing through the red ring representing the Taka Medal, he is surrounded in a red veil with wings, the yellow ring representing the Tora Medal gives an aura with claws, while the green ring representing the Batta Medal gives an aura with legs.

An artistic depiction of the King's Tatoba Combo shows him with a cape, a gauntlet similar to the Tajaspiner and a sword similar to the Medajaribur.

As Latorartar Combo, OOO can emit an infrared light called the Lio Diaz (ライオディアス, Raiodiasu), which is intense enough to incinerate, use the Toraclaws, and run at high speeds. The Cheetah Legs also enable Latorartar Combo to perform the Revol Spin Kick (リボルスピンキック, Riboru Supin Kikku).

Also, Latorartar Combo's Running Speed is faster than AccelTrial, although it sports weaker armor and greater agility, this Combo is better suited for high speed movement.

This Combo's Scanning Charge finisher is the Gouache Cross (ガッシュクロス, Gasshu Kurosu), which projects three yellow rings in front of OOO before charging through them with the Cheetah Medal's speed before delivering a cross slash on the target with the Toraclaws infused with the Lion Medal's energy projection.

The name of this Combo has been variably written as "Latorartah" and "Latoratar" in various print materials.

Although Sagohzo Combo is the toughest and strongest of the first five Full Combos, its jumping height is considered to be weaker and it has the slowest Running Speed.

This Combo's Scanning Charge finisher is the Sagohzo Impact (サゴーゾインパクト, Sagōzo Inpakuto), where OOO manipulates gravity to lift him into the air and weights himself down to hit the ground with a powerful stomp, trapping a Yummy in the ground that forms around it while the reformed ground moves toward OOO where he delivers a powerful double handed punch and headbutt at the same time. The damaged ground reforms after the Scanning Charge.

The Tako Legs allow Shauta Combo to climb walls with their suction cup-like abilities and can split apart for a barrage of hits.

Although Shauta Combo is better well-suited for underwater combat, its also very weaker than the other combos due to its punching and Kicking Power, but it has fantastic flexibility.

This Combo's Scanning Charge finisher is the Oct Vanish (オクトバニッシュ, Okuto Banisshu), where OOO liquefies his lower body to propel himself upward, then use the Unagi Whips to drag the opponent upward while OOO goes back down using the Tako Legs to form a drill to burst through the opponent.

Appearance: OOO Episode

Tajadol Combo

Tajadol Combo

"Taka! Kujaku! Condor! (Eagle screech) Ta~ja~dol!"
―Transformation announcement[src]
Rider Statistics
  • Rider Height: 198 cm.
  • Rider Weight: 87 kg.
Ability Parameters
  • Punching Power: 10 t.
  • Kicking Power: 15 t.
    • Prominence Drop:150 t.
  • Maximum Jump Height: 160 m.
  • Maximum Running Speed: 100 m. per 4 sec.

Tajadol Combo (タジャドルコンボ, Tajadoru Konbo), also known as the Blazing Combo (炎のコンボ, Honō no Konbo), is Kamen Rider OOO's red combination, using the powers of Ankh's Core Medals: Taka, Kujaku, and Condor. This combo's primary motif is the Phoenix, often called the king of birds and is a mix of different kinds of birds. In this form, the Taka Head becomes the Taka Head Brave (タカヘッド・ブレイブ, Taka Heddo Bureibu), with the eyes becoming red rather than the usual green, wings protrude from the Taka Head, and the hawk head symbol on the forehead becomes more prominent.

As Tajador Combo, OOO can see far distances, create energy peacock tail feathers to direct at opponents, use the Kujaku Wings to fly, project Core Medal-like energy at its opponents, shoot streams of fire and use the talon-like attachments of the Condor Legs called the Raptor Edges (ラプトルエッジ, Raputoru Ejji).

Tajador is shown to have an increase in power, speed, and defense, making it the most superior out of the other combos.

This Combo's Scanning Charge finisher is the Prominence Drop (プロミネンスドロップ, Purominensu Doroppu), where after sprouting wings from the Kujaku Arms, OOO flies into the air and performs a flying drop kick, with the talons on the Condor Legs splitting apart, on the target.

Putotyra Combo

Putotyra Combo

"Ptera! Tricera! Tyranno! (Screech) Pu-To-Tyrannosaurus!"
―Transformation announcement[src]
Rider Statistics
  • Rider Height: 205 cm.
  • Rider Weight: 95 kg.
Ability Parameters
  • Punching Power: 10.5 t.
  • Kicking Power: 20 t.
  • Maximum Jump Height: 210 m.
  • Maximum Running Speed: 100 m. per 3.3 sec.

Putotyra Combo (プトティラコンボ, Putotira Konbo), also known as the Invincible Combo (無敵のコンボ, Muteki no Konbo), is OOO's purple combination accessed by the Ptera, Tricera, and Tyranno Core Medals.

Along with Tajador Combo, Putotyra is easily one of the most powerful Combos in OOO's arsenal. Putotyra Combo has much higher Kicking Power, jumping height, and Running Speed than Tajador Combo, along with marginally higher Punching Power. It is also capable of destroying or damaging Core Medals, making this Combo more dangerous and destructive.

In this form, OOO uses wings on the Ptera Head, called the External Fins (エクスターナルフィン, Ekusutānaru Fin), to fly, as well as to freeze the opponent with a blast of icy air. The horns on the Tricera Shoulders, called the Wind Stinger (ワインドスティンガー, Uindo Sutingā), can stretch into various Heights according to Kings's command. The claws on the Tyranno Legs, called the Legsteranail (レグステラネイル, Regusuteraneiru), enhance his kicking. He can also combine the thigh armor to form a tail, called the Taildivider (テイルディバイダー, eiru Dibaidā), that can give off a devastating blow.

Unlike the other combos, Putotyra Combo causes most of the OOO armor to become white and cannot form a mismatch with the other Core Medals, as the purple Medals are made in nature as the antithesis of desire, negating the power of the other Core Medals. The O Scanner announces this Combo by the long name of Putoyrannosaurus (プトティラノザウルス, Putotiranozaurusu) rather than just "Putotyra".

Also, like Tajadol Combo, this Combo has its own weapon; an axe/bazooka-hybrid called the Medagabryu.

This Combo's Scanning Charge finisher is the Blasting Freezer (ブラスティングフリーザ, Burasutingu Furīzā). When activated, OOO uses his Tricera Shoulders' Wind Stingers to stab his opponents in the shoulders to hold them in place, while he uses his Ptera Head's External Fins to freeze them immediately after, and the Tyranno Legs' Taildivider to finish them off by smashing them into frozen shards.

This form is exclusive to the Kamen Rider OOO: Final Stage.
