OOO Driver
The OOO Driver is a belt that gives Eiji Hino the ability to become Kamen Rider OOO, originally the 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, turning the O Slater on the Force Drive, 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 who undid the seal on the OOO Driver itself, it will only work on 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.
O Scanner
The O Scanner 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. The O Scanner can also be used on the Cell Medals in the Medajalibur to initiate its Scanning Charge, designated as "Single", "Double", or "Triple", as well.
The Medajalibur is a sword that serves as Kamen Rider OOO's main weapon, given to him by the Kougami Foundation as a "birthday present". It can also be used to fire waves of energy to attack. By inserting three Cell Medals into the Medajalibur and scanning them with the O Scanner, it can be used to perform a slashing Triple Scanning Charge attack called the OOO Bash.The OOO Bash appears to slice through, not only the Yummy, but everything behind it, though anything other than the Yummy is restored afterwards. The name is a portmanteau of "medal" and Excalibur, the legendary sword from Arthurian myth.
O Medal Holder
The O Medal Holder is a special case designed to store O Medals, rather than merely being contained within Ankh's body. Although the O Medal Holder first appears in the Kamen Rider OOO: Nobunaga's Desire act of Movie War Core, in episode 17 of the television series it is revealed that Hina had commissioned its creation while she and Chiyoko were vacationing in Egypt.
Taja Spinner
The Taja Spinner is a shield-like gauntlet that can be summoned when the Kujaku Core Medal is equipped, first seen being used by Kamen Rider OOO Tajadol Combo. Powered by seven O Medals in its O Crown, it can be used either as a shield, to shoot powerful fireballs, or to perform a Giga Scan by changing some of the O Medals with Core Medals and then using the O Scanner, which continuously draws power from the Medals inside. Using Ankh's Core Medals in the Taja Spinner for a Giga Scan, Kamen Rider OOO can perform the Magna Blaze, generating a firebird-like aura around him before charging at an opponent.
The Medagabryu is a Putotyra Combo's signature weapon, enabling him to unleash the full potential of the Core Medals. It can change between its Axe Mode and its Bazooka Mode. When Cell Medals are inserted in the Medagabryu, Kamen Rider OOO can perform a Putotyranno Hissatsu depending on the weapon's mode. When in Axe Mode, Kamen Rider OOO can perform the Grand Of Rage slash, or the Strain Doom blast if the Medagabryu is in Bazooka Mode. The Medagabryu can be used with other forms. However, only Putotyra Combo is able to control it's Bazooka Mode
The Burahngi is a pungi-like weapon that can be summoned when Kamen Rider OOO is in Burakawani Combo. When Kamen Rider OOO plays a song into the Burahngi, Kamen Rider OOO can perform the Cappello Brush which summons a giant cobra from the top of his head
Birth Driver
The Birth Driver is the belt that enables the transformation into Kamen Rider Birth. After a single Cell Medal is inserted into the Birth-Slot, and the Grap Accelerator knob is twisted, the belt's Receptacle Orb's Trancer Shield is opened, encasing the user in the energy-based Cell Reactor as the Kamen Rider Birth armor forms around him. After inserting another Cell Medal and turning the Grap Accelerator again, Kamen Rider Birth can summon one of the Birth CLAWs units. By inserting two more Cell Medals into the belt, Kamen Rider Birth can initiate a Cell Burst attack.
Birth Buster
The Birth Buster is Kamen Rider Birth's personal sidearm. In its Normal Mode, it is a gun that uses Cell Medals as ammunitions, firing medal-shaped energy bullets. Kamen Rider Birth can reload the Birth Buster with Cell Medals by using the Cell Bullet Pod. In its Cell Burst Mode, the Birth Buster is capable of releasing an explosive ball of energy, so long as a Cell Medal has been inserted in it. The recoil of the gun is very powerful, as evidenced by Shintaro Goto was thrown flying backwards after firing just one shot, when he fired the gun first time. Date later allows him to use it, as so to prepare Goto in becoming Kamen Rider Birth once Date achieves his goal of acquiring one hundred million yen.
Cell Medals
The Cell Medals are silver O Medals as a manifestation of human desire. Unlike Kamen Rider OOO who uses Core Medals, Kamen Rider Birth uses these Cell Medals to transform or access weapons. These Medals can be used to transform into Kamen Rider Birth or used in a Cell Burst. No specific Cell Medal is required for Kamen Rider Birth to transform, summon a Birth CLAWs armament, or initiate a Cell Burst attack.
Birth CLAWs
The Birth CLAWs (Cannon/Leg/Arm/Wing System) is an armor system that consists of six armaments contained in Receptacle Orbs on the Kamen Rider Birth armor. Using a unit requires a Cell Medal as payment for it to emerge and attach to the Recepable Orb it came out from. Furthermore, the Birth CLAWs are magnetic and thus attract Cells Medals to them. Kamen Rider Birth can also use two or more CLAWs units at once by inserting in more Cell Medals into the Birth Driver.
Crane Arm
The green Crane Arm unit, referred to as the Springer Haken ("Jumper Hook" in German), is a powerful winch attachment that is contained in the Receptacle Orb on Kamen Rider Birth's right shoulder. The winch allows him to scale buildings as well as collecting any leftover Cell Medals with one sweep. This unit is first used by Nobunaga to fight the Pteranodon Yummy in Movie War Core.
Breast Cannon
The red Breast Cannon unit, referred to as the Salamander Launcher, is a powerful energy cannon that is held in the Receptacle Orb on Kamen Rider Birth's chest. Due to its size, using it hinders Kamen Rider Birth's mobility. The cannon can be charged up to multiple levels of power by using additional Cell Medals.
Drill Arm
The blue Drill Arm, or Brighton Bit , is held in the Receptacle Orb on Kamen Rider Birth's right forearm. Its powerful drill bit can extract Cell Medals or even Core Medals from the bodies of Greeed and Yummy, while dealing serious damage to their bodies. The Drill Arm can also be combined with the Crane Arm by activating both simultaneously, allowing Birth to use it as a powerful ranged attack.
Catepillar Leg
The purple Catepillar Leg, or Haze Crawlers, are held in Receptacle Orbs on Kamen Rider Birth's legs, and allow him to move easily over tough terrain and execute heavy kicks.
Shovel Arm
The orange Shovel Arm, or Vermillion Bucket, is held in the Receptacle Orb on Kamen Rider Birth's left forearm, increasing his power to where he can lift Yummy off of the ground with it.
Cutter Wing
The yellow Cutter Wing, or Solent Edges, is held in the Receptacle Orb on Kamen Rider Birth's back, allowing him to fly. The unit can also magnetically collect Cell Medals by flying over them.
CLAWs Sasori
When the six Birth CLAWs units combine, they create the CLAWs Sasori (CLAWs), an autonomous scorpion-like assault droid which has its master server and network connection installed in the Birth Helmood.
Birth Day
Birth Day is the name for when all six Birth CLAWs units are summoned and attached to Kamen Rider Birth. Costing six Cell Medals, it is extremely risky when Kamen Rider Birth activates this combination on his own, and requires Kamen Rider OOO to back him up.
