Eiji Hino

Kamen Rider OOO 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 a man who travels the world that has no dreams, no long-term job, and no family since his grandfather died. During one of his many travels Eiji met a little girl in a foreign nation who shared an item with him, they soon got caught up in a civil war and Eiji tried to help the little girl when she was in a war zone but was unable to do so in time because he was too weak from hunger and the girl was killed in an explosion, which still haunts him to this day.

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.

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 Middle Eastern girl he befriended. He keeps a collection of coins and almost always pairs of underwear of different designs and colors which he at times even gives to others.

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 Combo, 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).

By placing seven O Medals 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.

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.

Medagaburyu
The Medagaburyuu (メダガブリュー, Medagaburyū?) is a special weapon that Kamen Rider OOO can use in Putotira Combo. In Axe Mode (アックスモード, Akkusu Mōdo?), it can store three O Medals and announces a Combo's name when three specific Medals are inserted in the "mouth". It can also change into its Bazooka Mode (バズーカモード, Bazūka Mōdo?) where the three Medals from the mouth transfer to the Medal Pod and initiate a final attack

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 Gorilla Candroid is a Gorilla Candroid developed by Kiyoto Maki for OOO. It has superhuman strength and can throw heavy objects. It also has the ability to sense the activity of a Yummy, to which is the reason why Date/Birth keeps several around. They are the sixth Candroid to appear, and the first Candroid to debut without OOO activating one. So far, Eiji/OOO or Ankh has of yet to use the service of a Gorilla Candroid.
 * The Kujaku Candroid is a Peacock Candroid developed by Kiyoto Maki for OOO. It can rotate its sharp, sawblade-like tail feathers to 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.
 * 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.
