Fullbottles



Fullbottles (フルボトル) are the sample bottle-like collectible devices used by the transformation gears in Kamen Rider Build. The majority of the Fullbottles are in a collection of 60 that are associated with each panel of the Pandora Box, with 20 Fullbottles representing each region of Japan: Touto, Hokuto, and Seito respectively.

Variants of Fullbottles include Sclashjellies, used by the Sclash Driver, Gears, used by the Nebulasteam Gun, and Evolbottles, used by the Evol-Driver.

Overview
The Fullbottles were originally created by the alien entity Evolto using memories of his host the astronaut Soichi Isurugi to enpower the Pandora Box so he could destroy the Earth as he did with Mars, however he was stopped by the Queen of Mars Vernage who possesed Isurugi's daughter Misora to eliminate the essence of the bottles resulting in the Skywall Disaster. Years later, under Evolto's Influence, the bottles were re-created by Takumi Katsuragi alongside the Build Driver as part of the first phase of Project Build. They contain purified Nebula Gas to allow a person with a Hazard Level of 3 or higher to transform into a powerful armored form with the Build Driver or Transteam Gun. At some point 20 of the bottles ended in Hokuto and the other 20 in Seito. Evolto (While possesing Isurugi) faked the robbery of the Driver and several Fullbottles as part of a plan to make Isurugi's daugther Misora (who was in charge of the purification process) believe that her job would be for a good cause. In order to make his plan work, Soichi/Evolto erased the memories and faked the death of Katsuragi who found out about Soichi's true identity and his true intentions. Soichi/Evolto also gave the Driver and the Fullbottles that he had stolen to an amnesic Katsuragi now bearing a new face and under the name Sento Kiryu, making him believe that he was a hero, while in reality he was unwittingly helping Soichi/Evolto further his evil schemes.

Ten unique pairs of purified and Best Matched Fullbottles from Touto exist, corresponding to Build's ten main forms. They are integral in Soichi/Evolto's scheme, as he intended to use them to unlock the Pandora Box and access its powers. Later, it was revealed that another ten pairs of Fullbottles each existed in Hokuto and Seito.

After Build defeats a Smash, an Empty Bottle (エンプティボトル) is used to absorb the Nebula Gas from the victim, causing the Bottle to swell and gain a black spiderweb pattern and a Transgel Solid inside (often colored after the Smash, not the Fullbottle it will become), becoming the Smash Bottle (スマッシュボトル). Through a mysterious power held by Misora Isurugi, her gold bracelet, and a modified microwave machine in nascita's basement made by Sento, the harmful properties are purified, leading to the creation of a Fullbottle which can then be used by Build. Sento's machine isn't needed for the process, but reduces the amount of exhaustion Misora suffers following it; from a full week being unconscious to only a few hours of exhaustion.

Before undergoing the purification process, the contents of a Smash Bottle can be poured back upon the victim, transforming them back into a Smash. However, if one uses a Smash Bottle with a lethal amount of unpurified Nebula Gas inside it, they will disintegrate and die.

The power of a Rider may also be absorbed in order to create Fullbottles. Fullbottles made in this way allow Build to take the form of the Rider whose power was absorbed. In addition, the Rider whose power was taken will be rendered unable to transform. If the Rider wishes to take their power back, he/she must shake the Fullbottle(s), releasing the powers and contents and sending it back to him/her.

Functionality
Kamen Rider Build transforms by inserting two Fullbottles into the Build Driver and turning the lever. Organic-type Fullbottles (有機物系のフルボトル) are inserted into the right-hand slot, and form Halfbodies that affect the left side of Build's head, his right arm, and his left leg. Inorganic-type Fullbottles (無機物系のフルボトル) are inserted into the left-hand slot, and form Halfbodies that affect the right side of Build's head, his left arm, and his right leg. Any pair of organic and inorganic Fullbottles can be used to create a Trial Form (トライアルフォーム), but each Fullbottle has a Best Match (ベストマッチ) with another Fullbottle, creating a perfect combination of powers that synergizes well. If they are used together, they create an especially powerful Best Match form.

Each Fullbottle has at least one Best Match with another specific Fullbottle, though individual Fullbottles can have multiple Best Matches depending on which Fullbottle is used.

Kamen Rider Cross-Z uses only the Dragon Fullbottle to transform, by inserting it into an adapter called the Cross-Z Dragon, and inserting it into the Build Driver.

Night Rogue and Blood Stalk use the Bat and Cobra Fullbottles respectively to transform by inserting them into the Transteam Gun.

Fullbottles may be inserted into certain weapons such as the Drill Crusher or Beat Closer to activate special finisher attacks. The Lion Fullbottle is used to turn the Build Phone from phone to bike mode.

Fullbottles can also be utilized to give their users (in civilian form) temporary superhuman abilities by shaking them (example: the Rabbit Fullbottle gives Sento temporary super speed and agility to evade attacks; the Dragon Fullbottle gives Ryuga powerful, fiery punches; etc.). Seemingly, the more a Fullbottle is used by someone without transforming, the more they synchronize with it.

Design
A regular Fullbottle consists of the following parts:


 * Shielding Cap (シールディングキャップ) - The cap on top of the Fullbottle. It is a protective valve that prevents the Transgel Solid inside the Fullbottle from leaking out. This is also why the label on the cap must be turned to face forward during transformation.


 * Material Absorber (マテリアルアブゾーバー) - The component on top of the Fullbottle on which the Shielding Cap is located. It is responsible for absorbing Nebula Gas from the Smash and putting it inside the Fullbottle. Additionally, when Build transforms, the Material Absorber is responsible for retrieving and assembling/disassembling Build's equipment.


 * Transgel Solid (トランジェルソリッド) - The liquid inside the Fullbottle. The liquid activates by stimulus, such as shaking, and when activated, forms Build's suit and armor.


 * Clear Mold Bottle (クリアモールドボトル) - The exterior of the Fullbottle, holding the Transgel Solid within. The Bottle is molded with a high strength, lightweight material, and the image cast on it shows the hidden ability inside the Fullbottle.

The RabbitTank Sparkling Fullbottle consists of the following parts:


 * Shielding Tab (シールディングタブ) - The tab on top of the Fullbottle. When pulled, the transformation system starts, and the RT-SP Connector (RT-SPコネクター) pops out at the bottom of the bottle, which feeds the ingredients inside the bottle into the Build Driver.


 * Material Absorber SP (マテリアルアブゾーバーSP) - A component absorbing device attached to the Bottle. When Build transforms, it retrieves and re/disassembles equipment. Located inside the Build logo-imprinted section of the can above the Sparkling Indicator.


 * Sparkling Indicator (スパークリングインジケーター) - The light emmiting component of the bottle that takes the shape of Build's eyes. It shows the state of each component inside the bottle and emits light when the components are activated.


 * Hard Metal Can (ハードメタルカン) - The exterior metal plating that makes up the exterior of the can to protect the internal components. Inside is an inner tank filled with a foam substance called Best Match Liquid (ベストマッチリキッド), which was developed using the Transgel Solid of the Rabbit and Tank Fullbottles and combining it with residue emmited from the Pandora Box. The Best Match Liquid is added as a material for suit and armor (most likely the white sections of the RabbitTank Sparkling Form) and enhances the performance of equipment.


 * Material Activator (マテリアルアクティベイター) - A vibration amplification device built into the Bottle. When shaking the bottle, the Material Activator amplifies the kinetic energy of the shaking and allows the components inside the RabbitTank Sparkling Fullbottle to activate faster.
