Eiji Hino

Kamen Rider OOO (仮面ライダーOOO(オーズ)) is the main Kamen Rider in Kamen Rider OOO. His title is pronounced similarly to both "Os," refers to the three O's in the series title which represent the character's transformation items, as well as meaning "multiple kings" (ｓ, Ōzu). The three O's also represent the infinity symbol with an additional circle over the center, stating that Kamen Rider OOO is Over Infinity. His debut was a cameo in the film Kamen Rider Double Forever: A to Z/The Gaia Memories of Fate where he fights against the Luna Dopant. Before Eiji Hino, there was a previous Kamen Rider OOO who had fought and sealed the Greeed away.

Eiji Hino
Eiji Hino (火野 映司, Hino Eiji, portrayed by Shu Watanabe ) (Age: 21) is the son of a politician who travels the world with his grandfather. While at Africa a year prior to the series, Eiji attempted to use his fortune to help out a village. However, his money was used to fund a civil war that cost the life of a little girl Eiji befriended whose death he was unable stop was forced to looked on helplessly. Though the Hino family used his sob story to get the people's support, the ordeal caused Eiji to lose any desire and become willing to help those in need, going so far to even risking his neck for complete strangers.

He returned to Japan to fund for more of his travels. His latest part-time job at the Kougami Art Museum ends due to the destruction of the museum around him, Eiji takes a strange red coin he found while off duty which he thinks is his pay. This causes a disembodied arm to begin to follow him around, until the arm announces that it is called Ankh and is one of the ancient beings known as the Greeed, and he needs Eiji's help to become King. When they are attacked by a monster called a Yummy, Eiji risks his life to rescue Ankh, who in return saves him and gives Eiji two more strange coins, calling them Medals, and a belt, enabling Eiji to transform into Kamen Rider OOO. After destroying the Yummy and further encounters with the Greeed, people from the Kougami Foundation begin to approach Eiji, offering their assistance in the fight against the Greeed and Yummy, but their true motives are not clear. He also gets a job and housing at the Cous Coussier after the owner Chiyoko Shiraishi finds out that he is a world traveler. In the process, joined by Akira Date, Eiji learns more of the Greeed's desire to become whole and the reason why Ankh is unable to assume his complete form. However, things changed when Eiji ended up becoming a host to half of a set of Purple Core Medals that react to his lack of selfish desires, the same presumed reason why he is able to use Kamen Rider OOO's powers without any sign of going berserk so far like the First OOO, with dangerous consequences.

Personality
Despite often coming off as happy go lucky in his personality, Eiji is actually quite strong willed and was easily able to pick up on the fact he could use Ankh's need for him and the OOO Driver to keep the Greeed in line. Another defining trait is Eiji will fight to protect anyone in need, even complete strangers and at the risk of his own life. This stemmed after his regret from not saving the little African girl he befriended during a civil war which his family fortune started. He keeps a collection of coins and almost always has pairs of underwear of different designs and colors which he at times even gives to others. Eiji possesses no selfish desires which made him ideal for being OOO but also became a weakness once the Purple Core Medals went into his body.

Combos
After Eiji inserts three Core Medals into the OOO Driver belt, scans them with the O-Scanner, and then holds the O-Scanner up to his chest, he transforms into Kamen Rider OOO. Like Kamen Rider Double before him, OOO has multiple combinations of forms he can access referred to as Combos (コンボ, Konbo?). Each aspect of a Combo gives OOO different powers and weaknesses. In a fight, if a particular section of OOO receives a significant amount of damage, the power of that section will be disrupted. If it takes further damage, the power will cut off completely and the section's corresponding Medal will be forcefully ejected from the OOO Driver, canceling the transformation. In addition, single-colored Combos are incredibly taxing on Eiji's body, as they embody the full power of the corresponding Greeed and fatal fatique if using more than one full combo as first seen in episode 15. Except for Tatoba and Tamashii Combos, the only combinations with "Combo" in their name are those of a single color while other mixed color combinations are known as Random Combos (ランダムコンボ, Randamu Konbo).

After 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.

According to Ankh, because it was Eiji that broke the seal on the OOO Driver itself, it will only work for him and no one else. However, someone else can perform the physical action of scanning Medals for Eiji as long as he is wearing the OOO Driver. The reason the seal broke was because of Eiji's lack of desire, which made him perfect to become OOO.

O Scanner
The O Scanner (オースキャナー, Ō Sukyannā?) is a device that is able to read the energy found within O Medals. By using the O Scanner on a set of three Core Medals in the OOO Driver, it allows for the transformation into Kamen Rider OOO or one of his various Combos. By scanning the Core Medals in the OOO Driver, again, it initiates one of Kamen Rider OOO's finishing attacks known as Scanning Charges (スキャニングチャージ, Sukyaningu Chāji?). The O Scanner can also be used on the Cell Medals in the Medajalibur to initiate its Scanning Charge, as well, however it has a different manner to use it's Scanning Charges.

Some are also exclusive to the game such as the Rider Medals that allow Kamen Rider OOO to transform into the Kamen Riders based on those Medals and perform their finisher attacks.

Core Medal
Core Medals (コアメダル, Koa Medaru?) are colored Medals used to transform into Kamen Rider OOO or any Combo which are acquired from a Greeed. These five types of Core Medals were originally fifty created by human scientists 800 years ago as a means to create artificial life, drawing from characteristics of different animals, forming the core of the Greeed before one Medal in each set was destroyed. Each set of Core Medals comes in a specific color and animal type. Red Core Medals have bird powers; yellow Core Medals have big cat powers; green Core Medals have insect powers; silver Core Medals have heavy mammal powers; blue Core Medals have marine animal powers; and purple Core Medals have dinosaur powers. The purple Core Medals are embodiments of hollowness that destroy desire. Five of these Medals enter Eiji's body when they sense his lack of desire, having a profound effect on him by allowing him to sense a Yummy and appearing on the OOO Driver on their whim. There are 60 Core Medals total from the series, each three from a Greeed divided in three groupings: Head, Arms, and Legs.

 * Gorilla Medal (ゴリラメダル, Gorira Medaru): The Gorilla Medal is the Gorilla-themed O Medal. As an Arms Core Medal it allows OOO to fire his Gori Bagon gauntlets at an opponent like missiles.
 * Kujaku Medal (クジャクメダル, Kujaku Medaru): The Kujaku Medal is the Peacock-themed O Medal. Until episode 20, Kazari took it for himself until Anhk stole it from him after making a diversion. It allows Kamen Rider OOO to use the Kujaku Arms, arming him with winged gauntlets called the Kujaku Wings and the Taja Spinner. Ankh finds another copy of this Medal during the events of Movie War Core.
 * Torikera Medal (トリケラメダル, Torikera Medaru): The Torikera Medal is the Triceratops-themed O Medal. As an Arms Core Medal, It allows OOO to use the Wide Stinger horns that are mounted on the Torikera Shoulders, which can stretch into various lengths according to OOO's command. Due to the Purple Cores being made to get rid of desire, the Torikera Medal cannot be used to form a Random Combo.
 * Panda Medal (パンダメダル, Panda Medaru): The Panda Medal is a white Core Medal themed after a Giant Panda that is given out with the March 2011 Televi-kun magazine. In Kamen Rider Battle: Ganbaride, it arms Kamen Rider OOO with the Panda Arms, arming him with gauntlets similar to the Tora Claws, essentially making it a white pallete swap of the Tora Claws.
 * Imagin Medal (イマジンメダル, Imajin Medaru): The Imagin Medal is a Momotaros themed Core Medal appearing in Let's Go Kamen Riders, created from Kamen Rider Den-O's body which arms OOO with the Imagin Arms.
 * Batta Medal (バッタメダル, Batta Medaru): The Batta Medal is the Grasshopper-themed O Medal given to Kamen Rider OOO by Ankh. As a Core Medal, it allows OOO to use the Batta Legs to jump and kick with great strength. When used in Scanning Charge or when energy is pushed into the legs, the legs become more grasshopper-like, allowing OOO to jump high in the air to perform a Rider Kick or to reach higher places. It was one of four initital Core Medals OOO could utilize, and once belonged to Uva.
 * Cheetah Medal (チーターメダル, Chītā Medaru): The Cheetah Medal is the Cheetah-themed O Medal. As a Core Medal it allows OOO to use the Cheetah Legs to move at blurring speeds and use rapid-fast kick attacks.

 * Zou Medal (ゾウメダル, Zō Medaru): The Zou Medal is the Elephant-themed O Medal. As a Core Medal it allows OOO to use the Zou Legs to cause minor earthquakes with a mere step of his foot.
 * Condol Medal (コンドルメダル, Kondoru Medaru): The Condol Medal is the Condor-themed O Medal. It allows Kamen Rider OOO to use the Condol Legs, allowing him to use talon-like attachments to enhance his kicks. Ankh found one during the events of Movie War Core. In the series, it was revealed that Kougami has a copy of this Medal, and intended to give to Eiji, but he declined so Ankh wouldn't leave Shingo's body to die but was later used during the fight with the Lion-Kurage Yummy.
 * Tyranno Medal (ティラノメダル, Tirano Medaru): The Tyranno Medal is the tyrannosaurus rex-themed O Medal. As a Leg Core Medal, it allows OOO to use the Tyranno Legs, which can use a tail to give a devastating blow by the use of the thigh armor and use the Legsteranail claws on the feet to attack enemies with kicks.

 * Shocker Medal (ショッカーメダル, Shokkā Medaru): The Shocker Medal is a Core Medal appearing exclusively in Let's Go Kamen Riders, created by Shocker for the Shocker Greeed which bears it's Eagle insignia. It allows OOO to use the Shocker Legs, which are very similar to the Condol Legs.

Cell Medals
Cell Medals (セルメダル, Seru Medaru) also come from the Greeed, but also make up the bodies of the Yummy. These Medals are a manifestation of human desire. While the Greeed were sealed away, the Kougami Foundation studied and gathered the Cell Medals, incorporating them in their Ride Vendor, Medajalibur, and Candroid technology. Whereas Core Medals can be used and reused without effect done on the Medals, Cell Medals only have a limited amount of energy and vanishing when the energy has been depleted.

King Medal
There is also a King Medal, as shown in a Foundation X, which is said to possess more power than the Gaia Memory.

O Medal Holder
The O Medal Holder (オーメダルホルダー, Ō Medaru Horudā?) is a special case given to Ankh by Hina Izumi after she had commissioned it while she and Chiyoko Shiraishi were in Egypt. Able to hold 24 O Medals. This first appears in the Kamen Rider OOO portion of Movie War Core, where Ankh gives Eiji three Medals for him to transform.

Medajalibur
The Medajalibur (メダジャリバー, Medajaribā) is a sword that serves as Kamen Rider OOO's main weapon. By inserting three Cell Medals into the Medajalibur and scanning them with the O-Scanner, it can be used to perform a slashing finishing attack called the OOO Bash (オーズバッシュ, Ōzu Basshu). Even without performing the finisher it is shown to be powerful enough to cut through anything in the line of its attack, even when it is a distance away. Interestingly when it cuts through inanimate objects like a building, the object reforms. Its name is a portmanteau of Medal and King Arthur's legendary sword, Excalibur.

Taja Spinner
The Taja Spinner (タジャスピナー, Taja Supinā?) is a shield-like gauntlet that is used by Kamen Rider OOO Tajadol Combo and random combos that include the Taka and Kujaku Medals. It can fire fireball and medal-like projectiles and a stream of fire, guard against attacks, and when used for physical attacks fire sprouts out of it. By placing seven Core Medals, Cell Medals, or a mixture of the two into its O Crown (オークラウン, Ō Kuraun?) and then using the O Scanner, Kamen Rider OOO can perform a Giga Scan (ギガスキャン, Giga Sukyan?) which continuously draws power from the O Medals. Using Ankh's Core Medals in the Taja Spinner for a Giga Scan, OOO can perform the Magna Blaze (マグナブレイズ, Maguna Bureizu?), generating a firebird-like aura around him before charging at an opponent.

The name given for this item in Hyper Hobby magazine's February 2011 issue is the "Tajyaspiner". "Tajya Spinner" has also appeared in Uchusen, volume 131.

Medagabryu
The Medagabryu (メダガブリュー, Medagaburyū?) is a special weapon that Kamen Rider OOO can use in Putotyra Combo. It can change between its Axe Mode (アックスモード, Akkusu Mōdo?) and its Bazooka Mode (バズーカモード, Bazūka Mōdo?). The Medagabryu can draw out the full potential of the Core Medals, as when specific Core Medals are inserted it will say the name of a Combo (for example when inserting the Taka, Tora, and Batta Medals, it will announce "Tatoba"). When Medals are inserted in the Medagabryu, Kamen Rider OOO can perform a Putotyranno Hissatsu (プトティラノヒッサツ, Putotirano Hissatsu?). It's finishers are called: Ground of Rage (Axe Mode), and Strain Doom (Bazooka Mode).

Ride Vendor
The Ride Vendor (ライドベンダー, Raido Bendā) is OOO's and other's personal modified Honda VT 750 C2B Shadow Black Spirit mass produced by the Kougami Foundation. It can transform from its Machine Vendor Mode (マシンベンダーモード, Mashin Bendā Mōdo?), where it acts as a vending machine which holds the Candroids, to its Machine Bike Mode (マシンバイクモード, Mashin Baiku Mōdo?), when a Cell Medal is inserted and touching the Multi TaS Center (マルチＴaＳセンサー, Maruchi Tasu Sentā?, "Touch and Scan"). This allows the Ride Vendor to remain in plain sight until needed. The Ride Vendor's transformation can also be controled remotely, but this fact is hidden from Ankh and Eiji, as Kousei Kougami wants them to be dependent on his technology so he can collect Cell Medals from Kamen Rider OOO's fights.

Toride Vendor
By combining with the Tora Candroid, the Ride Vendor can become the Toride Vendor (トライドベンダー, Toraido Bendā). As the Toride Vendor, it's speed and power is increased and can use the claw-like attachments to release Medal shaped blasts of energy. But due to its feral nature, the Toride Vendor is only compatible with OOO while he is in his Latorartar Combo, with the machine's ability to siphon the excess energy allowing OOO to use the Combo without overexerting himself while taming the living super bike.

Candroids
The Candroids (カンドロイド, Kandoroido) are special support robots that are held within the Ride Vendor. After inserting a Cell Medal into the Ride Vendor in its vending machine mode, a beverage can-like device is "bought" from the machine. The Candroid is transformed from its Can Mode (カンモード, Kan Mōdo) into its Animal Mode (アニマルモード, Animaru Mōdo) through the pull-tab on top. Normally, a large number of them can be deployed from the Ride Vendor, but only one needs to be manually activated, the others simply activating on their own soon afterwards.
 * The Taka Candroid (タカカンドロイド, Taka Kandoroido) is a Hawk Candroid with an Animal Mode can fly, and is primarily used by the Kougami Foundation to gather Medals or performing recon. It is the first of the Candroids to appear.
 * The Tako Candroid (タコカンドロイド, Tako Kandoroido) is an Octopus Candroid, it's Animal Mode is a flexible flyer that can join with fellow Tako Candroids to form various things like roads, bungee cords, or trampolines. It flys by spinning in a helicopter fashion or like an actual octopus. And much like an actual octopus, the Tako Candroid is capable of releasing ink to aid in escape. It is the second of the Candroids to appear and the most used for support in handling Yummies.


 * The Batta Candroid (バッタカンドロイド, Batta Kandoroido) is a Grasshopper Candroid with an Animal Mode that has the ability of hopping to long distances and shoot medals. It also has the ability to transmit messages through other Batta Candroids, used as video cameras for recon purposes, or to trick people with, as was the case of Ankh tricking Uva that he left. It is the third Candroid to appear, but did not first come from a Ride Vendor, but rather as a deal proposition for Eiji and Ankh as a field test before being put into the Vendors themselves.
 * The Tora Candroid (トラカンドロイド, Tora Kandoroido) is a Tiger Candroid created by Kiyoto Maki who personally gives it to Eiji. It can enlarge itself and combine with the Ride Vendor to become the Toride Vendor. It is the fourth Candroid to appear, and is the first one to truly be of an offensive nature.
 * The Unagi Candroid (ウナギカンドロイド, Unagi Kandoroido) is a Electric Eel Candroid developed by Maki and sent to OOO by Goto (at first Eiji thought they were snakes). It is designed to gather Cell Medals more effectively with an Animal Mode that has the ability to create electric shocks, and can form a restraining cable of sorts when several Unagi Candroids link up together. They are not that durable, as outside help can remove the linked up Unagi Candroids, so long as the means isn't conductive. They are the fifth Candroid to appear.
 * The Kujaku Candroid is a Peacock Candroid developed to gather Cell Medals more smoothly, first used by Erika Satonaka to deliver the Condol Medal to Kamen Rider OOO during the rematch fight with the Lion-Kurage Yummy. It can rotate its sharp, sawblade-like tail feathers at great speeds to propel itself, create small tornados, shread through foes, and to hover in the air. They are the seventh Candroid to appear, but in it's first appearence, it was just sitting on Kougami's desk.
 * The Ptera Candroid is a Pteranodon Candroid is a next-generation Candroid developed to utilize the Cell Medal energy more efficiently. It moves better than other Candroids and can transfer information via ultrasound. Like the Taka Candroid it is capable of flight and is more useful in combat, but even then, they are not quite as durable and an enhanced Yummy can take them out in one swing if it connects. They are the eighth Candroid to appear, and once more not first used by OOO, as Dr. Maki first used them as a desperate ploy to save Chiyoko Shiraishi from his own Yummy.
 * The Torikera Candroid is a Triceratops Candroid is a next-generation Candroid developed to utilize the Cell Medal energy more efficiently. Compared to other Candroids, the Torikera Candroid seems to have very limited mobility. They seemed to be a successor to the Gorilla Candroid in the aspect of delivering Cell Medals to Birth, as well as being a ranged combat-orientated Candroid. They are the ninth Candroid to appear, and once more not first used by OOO, as Birth first used it after finding the lone Candroid in Dr. Maki's trashed lab after the latter abandoned Kougami Foundations.
 * In Kamen Rider Battle: Ganbaride, Kamen Rider OOO and Ankh have access to the Furifuri Candroid (フリフリカンドロイド, Furifuri Kandoroido?), a teal-colored Candroid that when used grows several times in size and after it is shaken and opened, it releases a blast of energy in an attack called the Furifuri Can Hour (フリフリカンアワー, Furifuri Kan Awā?), similar to soda can eruptions.
