Fullbottles (Build)

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.

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 contain purified Nebula Gas and allow a person with a Hazard Level of 3 or higher to transform into a powerful armored form when used in the Build Driver or Transteam Gun. They may also be used in the Evol-Driver, which the Build Driver was based off of.

The Fullbottles were originally created by the alien entity Evolto based on memories of his host, the astronaut Soichi Isurugi. Evolto did this by asking Soichi questions. He first asked him for 30 things that he liked. Soichi answered with things from Misora's picture book, which were then used to create the Organic Fullbottles. Evolto then asked Soichi to name 30 things that could destroy each of the ones he had just named. Soichi initially answered with objects such as tanks and guns, but soon started naming random objects in an effort to protect the things that Misora loved once he realized Evolto's motives. Pairing an Organic Fullbottle with the Inorganic Fullbottle representing the item intended to destroy it results in a particularly powerful combination, called a Best Match.

Originally, the sole purpose of the Fullbottles was to allow Evolto to open the Pandora Box, giving him access to his full power so that he could destroy the Earth as he did with Mars. However, the Queen of Mars, Vernage, had possessed Isurugi's daughter Misora and removed essence of the bottles. Evolto trying to open the Pandora Box with the blank Fullbottles resulted in the Skywall Disaster. Years later, with Evolto's help, the bottles were restored by Shinobu Katsuragi. His son, Takumi Katsuragi, studied the Fullbottles and Nebula Gas for Project Build, resulting in the creation of the Build Driver and the Rider System.

At some point, several Fullbottles lost their essence and many of them were scattered over Japan. To quickly collect the Fullbottles again and use them to open the Pandora Box, Evolto wiped Takumi Katsuragi's memory and convinced them that needed to defeat Smash and obtain Fullbottles in order to protect Touto.

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 Vernage's power inside of Misora Isurugi's 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 side effects that Misora suffers from a full week of unconsciousness 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.

The FullFull Rabbit Tank Bottle consists of the following parts: The Genius Fullbottle consists of the following parts:
 * Selecting Cap (セレクティングキャップ) - The gold cap on the bottle. It is a form selecting device. Twist the selecting cap to the form desired. The Selecting Cap is normally on a neutral green state, but if Build desires, the Selecting Cap can be twisted to reveal either a red rabbit (for RabbitRabbit) or a blue tank (for TankTank). The desired side is displayed on the Revol Indicator.
 * Revol Indicator (リボルインジケーター) - The display panel on the gold side of the bottle. It displays what side of the Selecting Cap is selected.
 * Material Absorber FFRT (マテリアルアブゾーバーFFRT) - A material absoring device in the gold section of the bottle. It is responsible for materialising the Fullbottle Buster and armor of RabbitRabbit and TankTank.
 * FullFull Indicator (フルフルインジケーター) - The display panel on the silver side of the bottle. It is a light emitting device that shows the state of the FullFull Rabbit Tank Bottle's insides. It will glow red if the insides are ready to transform into RabbitRabbit, and will glow blue if ready for TankTank. It will also emit light during deathblows.
 * Material Activator FFRT (マテリアルアクティベイターFFRT) - A vibration amplifying device built into the silver section of the bottle. By shaking the bottle, the material inside will activate, allowing Build to activate the components inside each tank simultaneously.
 * Hard Progress Metal (ハードプログレスメタル) - The exterior metal parts of the bottle. It is composed of the same components that make up Build's Hazard Form armor, and is designed to suppress the intense internal reaction in the bottle. Components from the Rabbit and Tank Fullbottles are filled in the inner tank one by one, forming a universal regulator called Stabiliser Vapor (スタビライザヴェイパー), which is made due to interference of the same component at room temperature. Furthermore, the Stabiliser Vapor suppresses the side effects of the Progress Vapor (プログレスヴェイパー Puroguresu Veipā) from the Hazard Trigger.
 * Build Up Connector (ビルドアップコネクター) - The hinge and lock system of the FullFull Rabbit Tank Bottle. A hinge connects the two sections of the bottle together, which then separates and re-connects in a different configuration via slots on the insides. At the connecting part, interference between the substances from the Rabbit and Tank Fullbottles occur, creating the Stabilising Vapor. Additionally, a device that maximises the output of the Hazard Trigger is installed in the Build Up Connector, which, during the time of transformation, shifts Build's armor to a similar state as Hazard Form's Overflow mode.
 * Genius Connector (ジーニアスコネクター) - The connecting terminal locatd on top of the Genius Fullbottle, it sends armor and weapon components to the Build Driver.
 * Build Up Starter GN (ビルドアップスターターGN) - The button that activates the Genius Fullbottle. The user must have strong feelings that passes a certain threshold in order for the Build Up Starter GN to activate.
 * Shielding Cap (シールディングキャップ) - The cap of the Genius Fullbottle, it prevents an outflow of ingredients at the wrong time. When transforming, the Build Up Starter GN is pushed first, before twisting the Shielding Cap to show the Build Logo at the front so that the Fullbottle's protection valve (located at the Genius Connector) opens. The user then inserts the Genius Fullbottle to the Build Driver to start transformation.
 * Material Absorber GN (マテリアルアブゾーバーGN) - A component absorbing device located in the top silver part of the Genius Fullbottle. During transformation, it releases components necessary for armor and weapons.
 * Full Build Indicator (フルビルドインジケーター) - A light emitting display in the middle of the Genius Fullbottle, it shows the state of each components. When activating transformation or charging up deathblows, the Full Build Indicator will glow vividly, displaying the Build logo.
 * Material Activator GN (マテリアルアクティベイターGN) - A vibration amplifying device located in the bottom silver part on the Genius Fullbottle's base, it quickly acivates the internal components via stimulus, and can amplify vibration by 60 times to activate components quicker. Because it is highly sensitive, it can even respond to small vibrations such as loading and removing the bottle from the Build Driver.
 * Metal Pandoram (メタルパンドラム) - The exterior metal parts that protect the Genius Fullbottle's interior. It has a double structure akin to a chemical drum can, and uses high strength frame parts similar to the material that makes up a Pandora Panel. Inside is an internal space compression container, which holds seperate containers for all 60 Fullbottle essences, as well as Progress Vapor (from the Hazard Trigger) and Stabilising Vapor (from the FullFull Rabbit Tank Bottle). During transformation, they are sent to a special miniature processing facility called the Plant Ride Builder GN (プラントライドビルダーGN), which automatically develops during transformation. All essences stored inside of the Metal Pandoram is sued as armor components.
