OOO Driver: The object that allows the user to become Kamen Rider OOO. It should be noted that the Driver can only work for one being that it has “bonded” to (we tested this, Katsuo is the only one it works for). The Driver functions using a combination of three Core Medals in the three slots, the combination of which determines the form and powers the form will take and have. When attached to the user the Driver creates a belt that had a Scanning Disc for activating transformations and powerful finishing moves (Scanning Charges), a small pouch for carrying Cell Medals, and a single edged sword called Medajalibur.
Core Medals and Their Respective Powers: There are seven colors of Core Medals, each possessing nine Medals, three of each type. In terms of usability by OOO, they fit into either Head, Torso, or Leg categories. Each one also has an animal theme.
Note that the names of Medals will either be in Neighponese/Japanese or an oddly pronounced form of Equestrian/English that Katsuo has dubbed “Engrish.”
Red: Bird
Head: Taka (Hawk). Allows the user enhanced sight including telescopic vision and a sort of X-Ray vision.
Torso: Kujaku (Peacock): Summons a small shield-like item referred to as the “Taja Spinner” on the left arm. This object has seven slots for Medals, usually filled with Cell Medals, but can have Core Medals inserted instead. Can shoot balls or streams of fire, has a fiery melee attack, and can block attacks. In addition it can perform an additional Scanning Charge referred to as a “Giga Scan.”
Legs: Condor. Allows the feet to function as “talons,” energy projections of blades on the feet.Yellow: Big Cat
Head: Rion (Lion). Allows the user to project a blinding light from their head.
Torso: Tora (Tiger). Gives the user folding bladed gauntlets. As well as functioning as melee weapons they can fire energy blades the claws for a projectile attack.
Legs: Cheetah. Super speed and rapid kicks.Green: Insect
Head: Kuwagata (Stag Beetle). Has two mandible like horns that can be used for melee. Can also discharge electrical attacks.
Torso: Kamakiri (Praying Mantis). Gives the user two large collapsible arm blades.
Legs: Batta (Grasshopper). Increased jumping ability and kicking power.Grey: Heavy Animals
Head: Sai (Rhino). Gives the user a sturdy single horn.
Torso: Gorilla. Gives the user two club-like bludgeoning fists and increased arm strength. Can fire the fists off for a projectile attack.
Legs: Zou (Elephant). Increased leg strength and being able to produce shockwaves by stomping.Blue: Aquatic Animals
Head: Shachi (Orca Whale). Allows the user to breathe underwater, use echolocation for sonar, and firing high velocity blasts of water.
Torso: Unagi (Eel). Gives the user two whips that can channel electricity.
Legs: Tako (Octopus). Allows the user’s legs to easily stick to any surface and transform into tentacles for combat.Orange: Reptiles
Head: Cobura (Cobra). Gives the user infared vision.
Torso: Kame (Turtle). Gives the user two shield gauntlets that can project energy barriers.
Legs: Wani (Alligator). Allows the user to attack with a chomping attack from the legs.Purple: Dinosaur
Head: Ptera (Pteranodon). Gives wings to allow for flight.
Torso: Tricera (Triceratops). Gives the user two extendable shoulder horns.
Legs: Tyranno (Tyrannosaurus). Gives the user clawed feet and a powerful tail.Cell Medals: Like Core Medals, Cell Medals are also concentrated Desire, but are much less powerful. They can be used for certain abilities, but disappear after their power has been expended, unlike Core Medals which seem to be able to use their power indefinitely. Cell Medals are not entirely uniform, but they are all silver in color and have the same effect and power.
Full Combos: Full Combos occur when the three slots of the OOO Driver are filled by Core Medals of the same color. This not only allows the user to use all their powers, but provides a significant power boost and grants more abilities. It also puts increased strain on his body.

Added Abilities: Can expel ice and freezing gusts of wind.WARNING: Katsuo has mentioned that while power it may cause him to go into a “Berserker Mode”, where he attacks whatever currently has his attention, friend or foe. This would also exhaust him more than if he was in control of the Full Combo. As such, he is going to what he can to not use it as to not risk Berserker.
Weapons: Katsuo has mentioned that OOO has two weapons, although at the moment he only has one. However, he mentioned that the other may become available to him in the future.
Medajalibur: A single edged sword about three feet in length. It also has a slot to insert Cell Medals, and can hold up to three. OOO can use this as a melee weapon or, after inserting one, two, or three Cell Medals, can perform a Scanning Charge for a powerful attack and finishing move. The most powerful, a Triple Scanning Charge, Katsuo describes as having the effect of seeming to slice through reality. However, he also mentions that anything aside from an enemy that was cut by this immediately returns to its original state. The enemy is destroyed.
Medagabryu: An axe-like weapon that is associated with the PuToTyra Combo, though can be used by other forms. It can use Cell Medals to use a powerful strike that actually has the power to destroy Core Medals. In PuToTyra mode it can be changed to be used like a cannon (Katsuo called it a “bazooka”) and unleash a powerful projectile attack. Katsuo mentioned he is unlikely to gain this weapon unless he uses the PuToTyra Combo, so with the previous warning in mind it is unlikely he will have access to it anytime soon.
Greeeds: Sapient creatures of concentrated Desire that possess magic-like powers. Each one is based one is based on a certain category of animals based on the Core Medals that make them up. Each one has their own particular motivations, but in the end are all based upon fulfilling some desire, which they will go to any length to satisfy, no matter whom or what is in their way.
Cell Medals help make up their body, while Core Medals are more their soul. Each one has one Core Medal that functions as their “brain,” and if it is destroyed they will not be revived even if the other eight Core Medals are intact. Once they retrieve all nine Core Medals of their main color, they will obtain a massive increase in power and abilities, to the point that some even have slight reality-warping powers.
Greeeds can absorb Core Medals from colors other than their own colors, gaining them powers that they would not receive normally. However, doing so too quickly will cause them to go out of control and simply become raging monsters. A Greeed may gain control over these powers if they add other Core Medals slowly and give their body time to adjust. It should also be noted that no matter how many other Core Medals they gain, a Greeed will not unlock their Nine Core Medal form without all nine Medals of their own color.
Yummys: Yummys are created when a Greeed implants a Cell Medal inside of a pony, and are made entirely out of Cell Medals. A Yummy’s only purpose is it accumulate more Cell Medals, which it does by fulfilling the desire of the one it was born from, often twisting that desire in a way that makes it easily fulfilled and often destructive. It should be noted that although they sometimes have a bit of personality, Yummy’s are not truly sapient.
A Yummy’s form and type will be based upon the Greeed that created, and the Desire that it was born from will also have an effect on its form and abilities. The pony who the Yummy was born from may or may not be aware of they Yummy’s existence, and even may be put under a state of euphoria until they notice it. Other times they may be fully aware of its existence and embrace the Yummy entirely. A pony who rejects a Yummy may be snapped out of their euphoria, and those who embrace them will be snapped out when the Yummy is destroyed.
Types of Yummys
White Yummy: This Yummy is directly created from the pony and first appears as a mummy-like figure. After indulging in desire for some time, it will evolve into a more matured and unique Yummy.
Parasite Yummy: This Yummy will develop inside the host and will be able to control their actions, forcing them to indulge in their desire even against their will. It can also cause body alterations to the pony based on its form, and can eventually overwhelm the pony and take it’s true form. This Yummy is particularly dangerous because if the host is not removed from the Yummy, they could be destroyed along with it. A host can by physically forced from the Yummy, or it might decide to leave on its own for whatever reason, but can easily retake its host.
Nest Yummy: A nest Yummy is unique in that a gathering of fish-like eggs will be created somewhere the host tends to be most often. As desire is accumulated it will increase in the number of eggs, and can actually spawn multiple identical Yummys. If the nest is not destroyed, it could potentially produce and infinite number of Yummys.
Self-Made Yummy: A Yummy created from the Greeed itself, this Yummy tends to be very basic and can fulfill whatever desire the Greeed was currently thinking of. It cannot actually increase the number of Cell Medals it has, as it was created from a Greeed and not a pony.
Egg Yummy: This Yummy first gathers desire as a bird like egg before hatching into a form similar to a White Yummy. It will then quickly evolve into a more unique Yummy.
Object Yummy: This Yummy is created from inanimate objects, and can have powers based upon the object or whatever feelings may have been attached to it. The Yummy born from it will be fully formed, skipping a development stage.
That’s all I have for now. If Katsuo remembers anything else, or we discover anything else, I’ll be sure to let you know.
Your Faithful Student,
Twilight Sparkle.
Celestia sat back and thought. On the one hand, this situation was more dangerous than she had thought, and she might have to take extra measures. On the other hoof, Katsuo giving up this much information proved that she had made the right decision, showing not only that he was the most knowledgeable on the subject but also that he was fully committed to protecting her subjects.
I look forwards to being able to publically thank you for your deeds, little hero, she thought with a smile.
