List of Kamen Rider Build characters
As well, she played a role in Project Build, as Evolto used Sōichi's memories of her drawings of organic and inorganic-based objects to influence Shinobu into developing the Best Match system.
The new world version of Misora regains the memories of her alternate self when the Pandora Box is reconstructed during Killbus's invasion and accepts Kazumi's proposal during the events of Downfall's attack.
[1] While possessed by Evolto, Sōichi utilizes the Cobra (コブラ, Kobura) Fullbottle in conjunction with the Transteam Gun (トランスチームガン, Toransuchīmu Gan) to transform into Blood Stalk (ブラッドスターク, Buraddo Sutāku).
[1] After Sento and Ryuga are transported to the new world, the Hokuto Three Crows regain the memories of their alternate selves and their ability to transform while fighting alongside Grease against Downfall.
He was once a eccentric but kind-hearted patriot, but his personality was altered after the Skywall Disaster and he became a sadistic and power-hungry maniac, performing questionable acts to ensure Touto's safety after deeming his father's pacifism a liability.
After taking his late friend's position as the prime minister's advisor, Gentoku took the mantle of Night Rogue (ナイトローグ, Naito Rōgu) and declared leadership over Faust.
Until he destroyed the Martian civilization, he was rendered incorporeal and lost his true physical form before Vernage sealed him and his damaged Evol-Trigger (エボルトリガー, Eboru Torigā) within the Pandora Box.
But this plan backfired, as his attempt to possess Namba Industries security guard Yuri Banjo resulted in the fragment assimilating into her unborn child Ryuga.
13 years later, Evolto possessed the astronaut Sōichi Isurugi when he retrieved the Pandora Box from Mars and attempted to destroy Earth, only for Vernage's intervention to result in the Skywall Incident.
This forced Evolto to execute a decade-long plan of manipulating various individuals and events, such as the foundation of Faust, becoming part of Namba Heavy Industries, and grooming Ryuga as his next vessel.
Evolto also used Sōichi's connections to force Shinobu and his son into working for him, tricked a young Misora into purifying Fullbottles, and framed Ryuga for Tarō's death while an unconscious Katsuragi was spirited away with his memory and face altered.
After all Fullbottles are purified, Evolto exposes his treachery to the crews of Nascita and his plans to use the Pandora Box to destroy Earth's civilizations, exploiting Namba as they engineer a series of schemes to take over Japan, with only Touto and its Kamen Riders opposing them.
Evolto also assumed Midō's identity to place the Blood Tribe as governors to execute Build Annihilation Plan, but a mutiny by Inō forced him into an alliance with his own adversaries.
After this, he falls back to his original plan of destroying all life on Earth, and as the final battle between him and the Riders commences, he kills Kazumi and Utsumi after the latter reveals his true allegiance.
The Smash (スマッシュ, Sumasshu) are monsters formed by humans injected with liquefied Nebula Gas (ネビュラガス, Nebyura Gasu) as part of Faust's experiments, with the subjects losing most of their memories.
He initially collaborates with Faust and Evolto to acquire the Build system for military applications, but has a secret agenda to use the Pandora Box's energy to create weapons of mass destruction.
In Build New World: Kamen Rider Cross-Z, when Killbus restores the Pandora Box, Utsumi's lack of Nebula Gas administration prevents him from regaining the memories of his alternate self.
Compared to the Build Driver, the Evol-Driver's Evol Match (エボルマッチ, Eboru Matchi) scrambles both elements of Fullbottles into a symmetrical form and is specially tuned for human use.
Having accidentally killed Kamen Rider Genm prior, Build went on to extract Ex-Aid's samples into a single Fullbottle before foiling Mogami's intent to cause a convergence between the two realities.
He later faked his suicide after cryptically informing Takumi that Ryuga is essential to stopping Evolto and his kin, enlisting Reika Kine's aid in smuggling himself out of Touto.
He suffered a heart attack during Faust's raid on a Touto facility, and entrusted Gentoku as acting prime minister, unaware that he is actually high-ranking Faust-member Night Rogue.
As a result, the Touto government is compromised until Sento and Ryuga defeat Night Rogue and expose his identity to Taizan, who orders his son to be taken into custody.
She is later brainwashed by Evolto and transformed into the Owl Lost Smash (オウルロストスマッシュ, Ōru Rosuto Sumasshu) before being defeated and freed by Kamen Rider Build's Genius Form.
Vernage leaves Misora's body to restore humanity and is transformed into the CD Lost Smash; she later transfers herself into Ryuga to counteract the psychological effects from the remnants of Evolto's genes.
Utsumi acquires the Kaiser System blueprints after Mogami's death and perfects the technology, which he gives to Seito as the developed Hell Bros gear the Washio brothers use.
Led by Killbus's younger brother Evolto, the four surviving Blood members caused the downfall of the Martian civilization and several other planets before possessing the four astronauts sent to explore Mars.
He becomes governor of Touto by the events of Kamen Rider Build the Movie: Be the One, after the Japanese civil war ends, and leads a mutiny against Evolto to carry out the Blood Tribe's initial plan to destroy Earth.
After Killbus is defeated and her students recover with the power of the Genius Fullbottle, she forgives Ryuga and the others and helps him with the sale of Sento's experiments, starting a new relationship with him in the process.
Using man-made Metal Bottles (メタルボトル, Metaru Botoru), they can transform into green-colored battle forms known as Phantom Crushers (ファントムクラッシャー, Fantomu Kurasshā).
He was originally one of Faust's scientists, who studied the Last Pandora Panel White alongside Shinobu Katsuragi and Evolto, but died as a result of their Lost Fullbottle experimentation.
