Eiji Hino

Kamen Rider OOO is the main Kamen Rider in Kamen Rider OOO. His title is an approximation of both "Os" and signifies the three medals he uses to transform, as well as meaning "multiple kings" (王ｓ, Ōzu) refering to the title the Greeed seek. The three O's themselves represent the infinity symbol with an additional circle. 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.

Eiji Hino
Eiji Hino (火野 映司, Hino Eiji, portrayed by Shu Watanabe ) (Age: 21) is a man who has no dreams, no long-term job, and no family; he is also an avid coin collector. Before he got his job as a security guard, he tried to help a little girl when she was in a war zone but was unable to do so in time. When 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 Anku and is one of the ancient beings known as the Greeed, and he needs Eiji's help to become the Multi King. When they are attacked by a monster called a Yummy, Eiji risks his life to rescue Anku, 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, 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.

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 Anku'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.

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.

OOO Driver
The OOO Driver (オーズドライバー, Ōzu Doraibā?) is a belt that gives Eiji Hino the ability to become Kamen Rider OOO. The belt is created from the same seal that kept the Greeed in their 800 year slumber. To transform into Kamen Rider OOO, Eiji inserts three Core Medals into the O Slater (オースレイター, Ō Sureitā?), turning the O Slater on the Force Drive (フォースドライブ, Fōsu Doraibu?), scanning the Core Medals with the O Scanner, and then holds the O Scanner up to his chest.

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?, designated as "Single", "Double", or "Triple"). The O Scanner can also be used on the Cell Medals in the Medajalibur to initiate its Scanning Charge, as well.

O Medals
The O Medals (オーメダル, Ō Medaru) are special medals that are the center of Kamen Rider OOO's different powers based on the animal the Medal represents. The O Medals are actually Core Medals that have been stolen from the Greeed and are now owned by OOO and Anhk.

Core Medals
Core Medals (コアメダル, Koa Mearu?) are colored Medals used to transform into Kamen Rider OOO or any Combo which are acquired from a Greeed. Each set of Core Medals comes in a specific color and animal type. Red Core Medals have bird powers; yellow Core Medals have large cat powers; green Core Medals have insect powers; silver Core Medals have heavy mammal powers; and blue Core Medals have marine animal powers.

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. Arms  Legs
 * Head
 * Taka Medal (タカメダル, Taka Medaru): The Taka Medal is a hawk O Medal given to OOO by Anku. As a Core Medal it allows OOO to use the Taka Head, allowing him to see far distances.

 * Kuwagata Medal (クワガタメダル, Kuwagata Medaru): The Kuwagata Medal is a stag beetle O Medal. As a Core Medal it allows OOO to use the Kuwagata Head, allowing him to have balance and stability. It is one of the two Core Medals OOO has obtained from Uva during his first fight with the Insect Greeed.

 * Gorilla Medal (ゴリラメダル, Gorira Medaru): The Gorilla Medal is a Gorilla O Medal. As a Core Medal it allows OOO to fire his large gauntlets at an opponent like missiles.
 * Batta Medal (バッタメダル, Batta Medaru): The Batta Medal is the grasshopper O Medal given to Kamen Rider OOO by Anku. As a Core Medal it allows OOO to use the Batta Legs to jump and kick with great strength. When used in Scanning Charge, the legs become more grasshopper-like, allowing OOO to jump high in the air to perform a Rider Kick. It was one of four initital Core Medals OOO could utilize, and once belonged to Uva.

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.

Ride Vendor
The Ride Vendor (ライドベンダー, Raido Bendā) is OOO'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. It can also combine with the Tora Candroid to become the Toride Vendor (トライドベンダー, Toraido Bendā).

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 larger Animal Mode (アニマルモード, Animaru Mōdo) through the pull-tab on top. Normally, a large number of them are deployed from the Ride Vendor, but only one needs to be manually activated, the others simply activating on their own afterwards.
 * The Taka Candroid (タカカンドロイド, Taka Kan Doroido) is a Candroid "bought" with the Taka Cell Medal. It's Animal Mode can fly, primarily used by the Kougami Foundation to gather Medals or performing recon. It is the first of the Candroids to appear.

It is the third and most recent of the Candroids to appear, but not from a Ride Vender, but as a deal proposition for Eiji and Ankh.
 * The Denki Unagi Candroid (電気ウナギカンドロイド, Denki Unagi Kan Doroido) is a Candroid "bought" with the Denki Unagi Cell Medal. It's Animal Mode has the ability to create electricity in it's head and swim under water.
 * The Tora Candroid (トラカンドロイド, Tora Kan Doroido) is a Can Droid "bought" with the Tora Cell Medal. It's Animal Mode has the ability to launch two Cell Medals (Tora and Cheetah) from it's claw. It can also combine with the Ride Vender.
