The publication date of this post is August 28th, 2011, the day the final episode of Kamen Rider OOO aired. To mark the occasion, let’s look at something I’ve sunk more money into this year than I care to think about: OOO’s henshin gear!

OOO Driver

OOO Driver

OOO’s henshin belt is the OOO Driver. “Driver” seems to be the new standard term for henshin belts, a bit of a shame they don’t come up with more unique names anymore. Names aside, the OOO Driver itself is pretty nice. The buckle is glossy black and silver with metallic blue “circuit” detailing. When wearing the belt, on your left hip is a small holder for easy access to up to six OOO Medals. This holder is amusingly styled after the type of belt mounted change holders a vendor on the street might use. On your right hip is the OOO Scanner, where all the electronics and magic really reside. I’ll discuss that more in a bit, but on the belt it has its own holster clip, keeping it securely in place when not in use. The straps for the belt also feature release buttons, allowing them to be easily detached from the buckle for display if you prefer.

OOO Medals

OOO Medals

The central theme of Kamen Rider OOO is OOO Medals. Each medal bears the crest of a particular animal, and grants OOO a unique power. Medals are primarily classified as Core Medals or Cell Medals, shown above the translucent Condor Core next to the dull gray Condor Cell. Core Medals are the “core” of the beings called Greeeds. Each Greeed has nine cores: 3 head cores, 3 body cores, and three leg cores. Which part of the body the core corresponds to is indicated by bars on the back of the medal: 1 for head, 2 for body, 3 for legs. You can see the back of the Kamakiri Core on the right has two bars, indicating it is a body core. Cell Medals “stick” to core medals to form the remainder of a Greeed’s body mass, and can be created by having a creature called a Yummy feed off human desire. In the context of the toys, Core Medals are made of translucent plastic with a gold painted metal ring. These medals feel very substantial when held, and are very nicely made.

Cell Medals are made from simple, unpainted gray plastic. This indicates their relatively lower value, and are not functionally interchangeable with the Core Medals. On the back of Cell Medals is a large “X”, since they do not activate any power for OOO (though they are utilized by Kamen Rider Birth).

Inside each medal is an RFID chip, which is activated and read when the OOO Scanner passes over it. This is the same technology being applied to credit cards and passports, allowing you to wave them near a pad for them to be read. IMO, this technology is better applied to toys, since the security implications make me cringe.

OOO Driver loaded

To use the OOO Driver, load three medals into it. They should be, in order, one head core, one body core, and one leg core. Above we see the three medals that make up OOO’s “default” form: Taka (head), Tora (body) and Batta (legs). In practice, the toy doesn’t really care. Put them out of order, use three head cores, use cell medals, it’ll still work in a basic sense. Once the medals are loaded, the front part of the buckle can be tilted to prepare for scanning.

OOO Scanner

OOO Scanner

Take the OOO Scanner, and squeeze the large button hidden inside its grip area. This will cause the scanner to light up and begin making a pulsing standby sound. Starting from your right with the head medal, run the scanner through the track along the bottom edge of the buckle so it passes over each medal in turn. As you pass the medals, the red lights along the front edge will illuminate one by one. If you go slowly, the scanner will announce the name of each medal as you pass. If you go quickly, it will announce them all at the end. Make sure to catch the hidden sensor at the end of the buckle to signal the scanner you’re done. The OOO Scanner will announce the names of the medals, then play a sound effect. The effect you get will either be generic, or a unique “jingle” if you scanned a special combo. The above set is OOO’s default TaToBa Combo. The scanner will play the special jingle for the combo: “Ta-To-Ba TaToBa Ta-To-Ba!” All the other combos are made up by using all three medals of the same color. These single color combos also get a sound effect related to the animal group they represent (screeching bird, buzzing insects, etc.) Here is the list:

TaToBaTakaToraBatta, OOO default combo
RaToraTahLionToraCheetah, cat combo
GataKiriBaKuwagataKamakiriBatta, insect combo
SaGouZouSaiGorillaZou, large mammal combo
TaJaDoruTakaKujakuCondor, bird combo
ShaUTaShachiUnagiTako, aquatic combo
PuToTyraPteraTriceraTyranno, dinosaur combo (in the show, these medals cannot mix with other medals)
BuraKaWaniCobraKameWani, reptile combo (movie exclusive)

To use OOO’s hissastsu techniques, scan the same set of medals you just scanned a second time, and the OOO Scanner will announce “Scanning Charge!” It will then play the combo’s animal noise if applicable, followed by a hissastsu sound effect.

OOO Medal Holder

OOO Medal Holder

It’s not long before the number of medals OOO and his partner Ankh are using becomes a bit difficult to manage. They begin to use a special OOO Medal Holder, which of course Bandai produced and sold. For what it is, it’s actually pretty nice. It’s made of the same glossy black plastic with metallic blue detailing as the OOO Driver. It has a really solid hinge, and two slide locks to keep it from spilling open. Inside, it’s lined with a sort of stiff foam rubber with cutouts for 24 medals. The medals fit snugly into the cutouts and do not tend to fall out. For what it is, it’s a pretty nice little piece, and a stylish way to house and protect the investment you made in all those medals. Shown here is my collection, featuring all 18 Core Medals from the TV series, and the Condor Cell which comes with the case itself. These are all the “deluxe” versions of the medals, rather than the gashapon or candy toy versions which are slightly lower quality. Here’s the breakdown of where the deluxe cores come from:

OOO Driver: Taka, Tora, Batta, Kamakiri
Medal Set o1: Lion, Cheetah, Kuwagata
Medal Set 02: Sai, Gorilla, Zou
TaJa Spinner: Kujaku, Condor
Medal Set 03: Shachi, Unagi, Tako
Medal Set 04: Ptera, Tricera, Tyranno

The Cobra, Kame and Wani cores come in Medal Set SP, which I haven’t been able to get ahold of yet. There’s also Medal Set EX, featuring the Cores from Kamen Rider OOO & W feat. Skull: Movie War Core, but their names aren’t actually spoken by the OOO Scanner. A few promotional medals like a kangaroo have also been released as magazine premiums in Japan, and they actually do work, though they aren’t part of any combo.

TaJa Spinner

TaJa Spinner

Though each body medal features a “weapon”, like the Tora Claws or the Kamakiri Blades, only two were released as actual toys: the TaJa Spinner and MedaGabuRyu. TaJa Spinner appears on the left arm whenever the Kujaku Core is used. In form, it’s sort of a small shield, looking like a giant Core Medal featuring the crest of the TaJaDoru combo. Detailing as expected of Bandai’s DX role play toys, is nice, but I feel like its design could use more variation of color. Its overall effect is rather bland. Functionality is also not all that great. There’s a trigger on the hand grip (which may be too small for adult hands). Pushing the trigger plays a sound of a fireball being launched, but a light on the front would have sold this much better.

TaJa Spinner action

TaJa Spinner is able to activate its own hissastu attack separate from Scanning Charge. To do this, open the TaJa Spinner and fill it with seven medals of any kind. Close the cover, and pull back the handle. When the OOO Scanner is set in the track at the front, it’ll press a button causing the medals inside to rapidly spin past. After they’ve all passed, push the scanner the rest of the way through to catch another sensor. It will announce the names of the first six medals that passed it, then say “Giga Scan!” After this, the trigger on the TaJa Spinner will play a bigger attack sound effect. Why they include space for seven medals when only six matter is curious. It seems they could’ve spaced them out and adjusted the timing so everything would just work with six, if that’s all the memory in the scanner can handle.

The OOO Driver is great. The medal system allows for a lot of variation, and they’re neat little collectibles. The belt itself is a blast, though the cost to get all the medals can be daunting. Try not to get scalped on the price of the medal sets, they’re not worth more than 1500 yen at most. The TaJa Spinner is a little more lacklustre. I just somehow expected… more. Even just the addition of a light on the front would have been a big improvement. If all you want is the Kujaku and Condor Cores, you may want to consider getting the gashapon or candy toy versions.
