The Transformation Smoke Pistol Transteam Gun (変身煙銃トランスチームガン, Henshin Enjū Toransuchīmu Gan) is the personal weapon and transformation device of Night Rogue and Blood Stalk. It is also the personal weapon of Kamen Rider Evol. It combines with the Steam Blade to form the Steam Rifle (スチームライフル, Suchīmu Raifuru).

It is a simplified version of Kaisei Mogami's Nebulasteam Gun created by Takumi Katsuragi, who worked as Kaisei's assistant. It operates solely on Nebula Gas, rather than the original's combination of Nebula Gas and Bugster Virus.

Unlike the Rider System, the Transteam System (トランスチームシステム, Toransuchīmu Shisutemu) does not rely upon the user's Hazard Level. This enables people that have not undergone extensive Nebula Gas experimentation to use it. As a result, however, it cannot raise the user's Hazard Level, meaning that the power of the transformation is fixed. ^{[Who Takes Off The Veil?] [ROGUE]} Hence, Transteam System users must rely solely on their own skill, abilities, and experience in fights.

The schematics for the Transteam Gun and its abilities are detailed in the 2nd file of Project Build.

Design

The Transteam Gun is composed of the following parts:

• Fullbottle Slot (フルボトルスロット, Furubotoru Surotto) - The slot of the Transteam Gun, it takes in a Lost Bottle (Cobra or Bat) used for transformation or a Fullbottle for an attack (i.e. Rocket). It has a function which activates the Transgel Solid inside of the Fullbottle via a special pulse, allowing the Transteam Gun to suck up the Fullbottle's essence.
• Blazing Steamer (ブレイジングスチーマー, Bureijingu Suchīmā) - The gun port of the Transteam Gun, it can shoot out bullets wrapped in hot steam called Steam Burettes (スチームビュレット, Suchīmu Byuretto) (On a side note, a Burette is a lab equipment used in chemistry to measure the volume of a liquid or gas. It consists of a glass tube with a stopcock at one end). Additionally, it also shoots out Transgel Steam (トランジェルスチーム, Toranjeru Suchīmu), which is used for transformation.
• Mystic Charger (ミスティックチャージャー, Misutikku Chājā) - The silver panel on the Transteam Gun with pipes on it. It is a steam generation unit which is directly mounted onto the gun. It heats up the Lost/Fullbottle's Transgel Solid (essence) and turns it into Transgel Steam, allowing transformation. In addition, Nebula Gas is stored inside of it's inner tank, allowing Night Rogue and Blood Stark to change humans into Smash whenever they desire without using laboratory equipment.
• Power Hit Grip (パワーヒットグリップ, Pawā Hitto Gurippu) - The hilt of the Transteam Gun. Because it is composed of materials that can withstand impacts, it can be used as an impromptu striking weapon. Additionally, a computer unit inside it uses combat data to figure out the user's combat style and adjusts shooting behaviour accordingly.

Functionality

Transformation

Fullbottles are loaded into the Transteam Gun to transform. Night Rogue uses the Bat Fullbottle to transform, and Blood Stalk uses the Cobra Fullbottle. The transformation command is "Jouketsu" (蒸血, "Jouketsu" lit. Blood Steam). According to Gentoku Himuro, to use the Transteam Gun, the user needs to have Hazard Level at a suitable level, albeit not as high as the Build Driver's requirement. ^{[Night Rogue Chapter]}

Users (chronological order)

User	Transformation	Episode Obtained	Description
Gentoku Himuro	Night Rogue	Prologue: NIGHT ROGUE RISES	The first Transteam Gun. Was created by Faust scientists along with Bat Fullbottle, placed in a glass case. When Gentoku announced the founding of Faust, he smashed the case and took the Transteam Gun and Fullbottle to transform, christening himself Night Rogue. He continued using it for 3 years, but lost it when it was presumably taken by Namba Heavy Industries Ltd. after his exile from Touto and given to Utsumi.
Evolto/Soichi Isurugi	Blood Stalk/Kamen Rider Evol	Pre-series	The second Transteam Gun. Evolto had already been in possession of one for an unknown period of time by the start of the series.
Nariaki Utsumi	Night Rogue/Kamen Rider MadRogue	Theory of Conspiracy (briefly) Kamen Rider Build: Raising the Hazard Level ~7 Best Matches~: First Chapter	Utsumi originally transformed into Night Rogue to act as Gentoku's decoy in order to keep his identity a secret, with the Transteam Gun being returned to its owner afterword. Later, he would take Gentoku's Transteam Gun and transform into Night Rogue several more times in order to collect data on Sento.

Finisher

The Transtream Gun has 2 finishers: the Steam Break (スチームブレイク, Suchīmu Bureiku) with the Bat Fullbottle or Cobra Fullbottle/Evolbottle and the Steam Attack (スチームアタック, Suchīmu Atakku) with any other Fullbottle.

When combined with the Steam Blade to form the Steam Rifle, its finishers are the Steam Shot (スチームショット, Suchīmu Shotto) with the Bat Fullbottle or Cobra Fullbottle/Evolbottle and the Steam Attack with any other Fullbottle.

Notes

• Being a transformation device that also doubles as a gun, it is similar to the Drake Grip, Diendriver, Break Gunner and Lupin Gunner.
  • Particular aspects make it closer to the Break Gunner, as it was designed to transform into a Rider-like form as opposed to the other aforementioned devices, and could use the collectible devices used by protagonists and antagonists of the series.
• Interestingly, Transteam Gun has both small and big models used in the series (as Soichi used the small one to transform and the big one once completing the transformation into Blood Stalk). The small model is likely the size of the toy version.
• The transformation call, Mist Match, could be a pun on the words mist and mismatch.
• This is the first transformation device to be used by the series antagonists, capable of combining with a sidearm for more powerful attacks, and make use of the series collectible to augment its power.
  • The closest comparison can be seen in Kamen Rider Chalice (being a series antagonist only by nature), when the Chalice Rouzer (the Rider's personal weapon) was inserted into the Chalice Arrow (the main weapon for the template of said Rider).
