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 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 (Build Driver), the Transteam Gun (represented as Transteam System (トランスチームシステム, Toransuchīmu Shisutemu)) does not increase the user's Hazard Level (which when raised, can increase the power of the user). Hence, Transteam system users rely solely on their own skill, ability, and experience in fights.

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

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 raise their Hazard Level first to a suitably high level, albeit not as high as the Build Driver requirement. ^{[Night Rogue Chapter]}

Users (chronological order)

User	Faust Generals	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	Pre-series	The second Transteam Gun. He has already been in possession of one for an unknown period of time by the start of the series.
Nariaki Utsumi	Night Rogue	Theory of Conspiracy (1st time; temporarily) Kamen Rider Build: Raising the Hazard Level ~7 Best Matches~: First Chapter (2nd time)	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 when he was being experimented on and transform into Night Rogue several more times in order to collect data on Sento.

Finisher

The Transtream Gun has 2 shooting finishers: Steam Break (スチームブレイク, Suchīmu Bureiku) with a Faust Fullbottle and Steam Attack (スチームアタック, Suchīmu Atakku) with a normal Fullbottle.

As the Steam Rifle, its shooting finishers are Steam Shot (スチームショット, Suchīmu Shotto) with a Faust Fullbottle and Steam Attack with a normal Fullbottle.

Notes

• Being a transformation device that also doubles as weapon (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.
• 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).
