Eiji Hino

'''

Kamen Rider OOO (仮面ライダーOOO(オーズ), Kamen Raidā Ōzu) is the main protagonist and one of the main characters in the series of 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" (王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. Also Kamen Rider OOO is the 100th Kamen Rider to be created.

Eiji Hino
Eiji Hino (火野 映司, Hino Eiji, portrayed by Shu Watanabe) is the son of an 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 to stop while he 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. Soon after, Eiji learns from Kousei Kougami, the Foundation's owner, that the only way to counteract the purple Core Medals is to acquire a desire of his own, something he is yet capable of.

Later on, he turns into the dinosaur-like Eiji Greeed (映司グリード, Eiji Gurīdo) after absorbing two more purple Core Medals from the other Purple Greeed, Kiyoto Maki, in a bid to make him go beserk. However, it was by then Eiji remembers his desire is to have the power to help others and later agrees to Kougami's suggestion to absorb all the Cell Medals in the Kougami Foundation's possession to achieve that desire. However, it does not halt Eiji's Greedification during his his final battle when he uses all the Cell Medals in his body in a risky attack that fails to destroy Maki. But before Eiji fully became a Greeed, Ankh gives Eiji his last three Core Medals, disappearing from Shingo and allowing Eiji to transform to defeat Maki, resulting in the destruction of the Core Medals along with Ankh's. As a now-normal Eiji falls back to the Earth, Ankh appears to him as his disembodied arm, saying his farewells, before disappearing into half of the broken Taka Medal that once held his consciousness. Saved by Kamen Rider Birth, receiving the other half of Ankh's Core Medal that Hina found, Eiji leaves Japan and resumes his journey around the world while find the way to fix the broken Taka Medal with a spectral Ankh arm following him.

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, he 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).

Tatoba Combo
Statistics Ability Perimeters: Tatoba Combo (タトバコンボ, Tatoba Konbo), known as the "Multi Combo" (複数コンボ, Fukusū Konbo), is the main combination that is always used by Kamen Rider OOO using the Taka, Tora & Batta Core Medals. As Tatoba Combo, OOO is armed with the Tora Claw gauntlets, and can transform his legs into Batta Legs to reach enemies that are out of his reach, such as ones that can fly. He can execute a Rider Kick called the Tatoba Kick (タトバキック, Tatoba Kikku), where after jumping high up through the Batta Legs, he descends with a drop kick through the three rings that form, which are in the primary colors of the Taka, Tora, and Batta Medals which surround him in auras depending on the Core Medals. 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. Like True Tatoba Combo, original Tatoba also can dual-wield the Medajalibur and the Medagabryu, as seen in The Shogun and 21 Core Medals.

 * After absorbing a vast amount of Cell Medals, Eiji uses the King's Core Medals which Kougami gave him to transform into a more powerful version of Tatoba Combo, variably referred to as "The Ultimate Tatoba Combo" (究極のタトバコンボ, Kyūkyoku no Tatoba Konbo) and "The True OOO" (真のオーズ, Shin no Ōzu). In this state, Kamen Rider OOO's power has increased to the point of momentarily surpassing the purple Core Medals, allowing him to dual wield the Medajalibur and the Medagabryu, as well as defeat a complete Greeed with the Tatoba Kick. However, because of the immense power that was brought from the immense number of Cell Medals within Eiji's body, these Medals overloaded and shattered.

The 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 Kamen Rider OOO's purple combination. Paring up with the famed Tajadol Combo, Putotyra is easily one of the most powerful combos but it will slowly turn him into a mindless beast if he stays in the Combo for too long until recently when Kamen Rider OOO managed to gain control of the Purple Cores (if barely) but he still suffers from the physical strain resulting from Combo use, and is still at risk of "letting himself go" if he does not consciously keep control. As a result of the purple Medals residing in his body, Eiji is undergoing a process known as "Greeedification", gradually turning him into a Greeed the longer the Medals are inside him. The Putotyra Combo has a power that is capable of destroying or damaging Core Medals. After Eiji gains two more Purple Medals, he can access this from in the usual way or straight into Putotyra while in Greeed form.

Unlike the other combos, the Putotyra Combo causes most of the OOO armor to become white and cannot form a mix and match 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 and it is announced by the call "Putotyrannosaurus" (プトティラノザウルス, Putotiranozaurusu) rather than just its name "Putotyra".

This combo consists of the Dinosaur Core Medals: the Ptera, Torikera, and Tyranno Medals. As Putotyra Combo, Kamen Rider OOO uses wings on the Ptera Head, called External Fins, to fly, as well as to freeze the opponent with a blast of icy air; horns on the Torikera Shoulders, called the Wind Stinger, which can stretch into various lengths according to Eiji's command; and the Tyranno Legs can form a tail, called the Tail Divider, that can give off a devastating blow. Also, like the Tajadol Combo, this Combo has its own weapon, an axe 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, Putotyra Combo using his Torikera Shoulders' Wind Stinger Horns to stab his opponents to stun them, while he uses his Ptera wings to freeze them immediatly after, and the Tyranno Leg's tail to finish them off by smashing them into frozen shards.

After the final battle against the Kyoryu Greeed, the Putotyra Combo is lost forever when the ten Purple Core Medals shattered when they reached the event horizon of the Greeed-made black hole, overloading on the emptyness.

Burakawani combo is Kamen Rider OOO's orange and reptilian Combo. It's Core Medals are the Cobra, Kame and Wani. Burakawani Combo is the movie-exclusive Combo in Kamen Rider OOO Wonderful: The Shogun and the 21 Core Medals. This Combo was (mysteriously) lost forever when the alchemist Gara was defeated. Burakawani Combo's body is covered in a substance called Soma Venom (ソーマ・ヴェノム, Sōma Venomu), which makes him able to heal instantly after taking any attack. As Burakawani Combo, Kamen Rider OOO's eyesight is doubled and gains infra-red vision, use the tutle shell-like Goura Guardner, and use the Saw Deadscythers on his legs to generate an energy crocodile, which chomps his enemies with every kick. In addition, he is armed with the Burangi, which lets him summon a giant cobra from the top of his head to attack enemies.

This Combo's Scanning Charge is the Warning Ride (ワーニングライド, Wāningu Raido) Rider Kick, where Kamen Rider OOO projects three orange rings in front of him before dashing through them in a foot-first slide before unleashing a powerful kick with the Saw Deadscythers.

"Burakawani" appears in official printed matirial regarding this combo.

Super Tatoba Combo
Super Tatoba Combo is Kamen Rider OOO's movie-exclusive combo in Kamen Rider x Kamen Rider Fourze & OOO Movie War Megamax. It is a more powerful version of Tatoba Combo accessed by the Super Medals. The colors of Super Tatoba are inverted compared to the original Tatoba Combo (meaning that he's mostly red, yellow and green and not black).

Super Tatoba Combo has the Super Taka Head, similar to the Taka Head Brave while in the Tajadol Combo, the longer and sharper Super Tora Solid tri-claws, and the spiked Super Batta Legs. This Combo's Scanning Charge finisher is a Rider Kick called the Super Tatoba Kick (スーパータトバキック, Sūpā Tatoba Kikku), which is a more powerful version of the Tatoba Kick..

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. 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. The Medajalibur's Scanning Charges are designated as "Single", "Double", or "Triple", depending if OOO has put the amount of Cell Medals, with the only difference between the Scanning Charges is the amount of energy is put out for the OOO Bash.

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. There are two different O Medals: Core and Cell. In Kamen Rider Battle: Ganbaride, toy version of the O Medals, both Core and Cell, can be used with the OOO style Ganbaride arcade machines to either change combos or initiate attacks. 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 O 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. However, as revealed by Maki, they made a sixth set of Core Medals: the Purple Cores, which were formed from the antithesis of desire and had the potential to shatter Core Medals with ease. Five of these Medals entered 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, but they also entered Dr. Maki due to his wish for the end of the world.

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; purple Core Medals have dinosaur powers; and orange Core Medals have reptilian powers. There are 70 Core Medals total from the series, each three from a Greeed divided in three groupings: Head, Arms, and Legs.

In the series finale, only 53 Core Medals that remained after Eiji and Maki permanently killed several of the Greeed, but all Core Medals except for one Core are seemingly destroyed when Eiji as able to defeat the Kyoryu Greeed, the Greeed absorbing all but one of the Core Medals, along with the Medal Vessel, in a black hole-like collapse of the Purple Core Medals' power, the Purple Cores shattering as they approached the event horizon, disappearing forever. That one Core Medal that was left is the split-in-two Taka Medal which formally contained Ankh's consciousness, Eiji now carrying it with him on his journey while find a way to fix the medal and revive him. However, in the Kamen Rider x Kamen Rider Fourze &amp; OOO Movie War Megamax, all desire-based types of Core Medals are reappeared again, along with Ankh.

There were also the King's Core Medals (王が持っていたコアメダル, Ō ga Tsukatteita Koa Medaru), which were originally part of the Core Medal sets that composed Ankh, Kazari, and Uva. Being the only tenth Core Medals separated from the rest of their respective sets instead of being destroyed, the King used them to become Kamen Rider OOO eight centuries ago. They were originally in Kougami's possession until he gives them to Eiji to become the true Kamen Rider OOO. These special Cores were first mentioned in a Foundation X report during the antepenultimate episode of Kamen Rider W, referred to as the King Medal (at the time, it was believed there was only one King Core) which are said to have more power than even the True Gaia Memory. However, prior to the final battle, the King's Core Medals are shattered due to the power of the purple Core Medals and the massive amount of Cell Medals in Eiji's body.

In the Tajadol Combo, the Taka Head becomes the Taka Head Brave. It was the first Core Medal to be seen in the series and was one of four initital Core Medals OOO could utilize. After Ankh's sacrifice, only one copy remained before it broke into two halves while the last intact copy was sucked into a black hole.

 * Kangaroo Medal (カンガルーメダル, Kangarū Medaru): The brown Kangaroo Medal was given out with the August 2011 issue of Televi-Kun magazine to go along with the Kamen Rider OOO Hyper Battle DVD. Unlike other Core Medals, the Kangaroo Medal can be used as either an Arm Medal where it arms Kamen Rider OOO with boxing gloves, as in the Combo Takagaruba (タカガルバ), or as a Leg Medal where it gives Kamen Rider OOO spring-loaded jumps and kicks while adorning him with what looks like sneakers, as in the Combo Takatoragaru (タカトラガル).

These Medals are based on the Rider Medals which used to be compatible with the Kamen Rider Battle: Ganbaride arcade game.

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.

Super Core Medals
Super Core Medals (スーパーコアメダル, Sūpā Koa Medaru) are enhanced Core Medals created from technology 40 years in future in Movie War Megamax, enabling Kamen Rider OOO to evolve his combo. They are similar in design to the Core Medals; but in addition to the gold edges, they also feature a gold design of the animal they represent. Only three Medals of Super Medals have been revealed in the movie. Michal Minato has obtained three Super Core Medals from the future and give Eiji the Super Core Medals from the future before going back to his time to protect it after realizing what it means to be a Kamen Rider.
 * Super Taka Medal (スーパータカメダル, Sūpā Taka Medaru): The Super Taka Medal arms Kamen Rider OOO with the Super Taka Head (スーパータカヘッド) Sūpā Taka Heddo), which looks similar to the Taka Head Brave in the Tajadol Combo.

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. It is able to hold 24 Medals, usually Cores. 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 Kujaku Medal. 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. a Giga scan can be performed by using only Cell Medals for a Non elemental attack but wont be as powerful as without Core 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.

Medagabryu
The Medagabryu (メダガブリュー, Medagaburyū) is Putotyra Combo's signature weapon, enabling Kamen Rider OOO to unleash the full potential of the Core Medals. 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 Cell Medals, as when specific amount of Cell Medals are inserted, it will say the name of a Combo followed by the karaoke of the Combo (for example when one Cell Medal is inserted, the Medagabryu will annouce "Tatoba". When two Cell Medals is inserted, it will annouce "Gatakiriba") except for the Tajadol Combo. When Cell 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) depending on the weapon's mode. When in Axe Mode, Kamen Rider OOO can perform the Ground of Rage (グランド・オブ・レイジ, Gurando obu Reiji) slash or the Strain Doom (ストレインドゥーム, Sutorein Dūmu) blast if the Medagabryu is in Bazooka Mode.

The Medagabryu can be used with other Combos in Axe Mode, but Bazooka Mode is only usable while in Putotyra Combo. The Medagabryu is the most dangerous weapon OOO can wield to the Greeed, because it has the power to destroy Core Medals, thus permamently killing a Greeed. It also can absorb a massive amount of Cell Medals to charge up its attack power, thus destroying a Greeed in one hit instantly if it properly hits.

Burangi
The Burangi (ブラーンギー, Burāngī) is a pungi that can use when Kamen Rider OOO is in the Burakawani Combo. When Kamen Rider OOO plays a song into the Burangi, a giant cobra is summoned from the Cobra Head's "ponytail" to attacks enemies. The Burangi are only appears in The Shogun and 21 Core Medals, though oddly, it didn't came as part of the full Combo, but rather, it was a tossed-aside flute in Feudal Japan. How a pungi appeared in Japan is unknown.

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. However, 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.
