Keiji Uraga (浦賀啓示 Uraga Keiji) is the main antagonist of Kamen Rider Build NEW WORLD: Kamen Rider Grease who is able to transform into Kamen Rider Metal Build (仮面ライダーメタルビルド Kamen Raidā Metaru Birudo). He becomes the new leader of the terrorist organization Downfall after killing Simon Marcus.

Character History

Keiji was a scientist who teamed up with Shinobu until his demise as the Zebra Lost Smash, like many of the previous Smash experimentation victims. During the Killbus incident, his memory returned along with his old wound that happened with other previous victims in the New World. After Keiji remembered the incident of the previous world, he took his goal which he couldn't accomplish before, becoming the "ruler of the world" by creating a terrorist organization and hid his leadership by using Simon Marcus as the fake leader of Downfall.

Keiji ambushed the Prime Minister building during Taizan, Shinobu, and Gentoku's introduction to Simon Marcus about their invention to protect the city, the Build Driver. Taizan and the others were unaware of Simon's status as Downfall's member. During the ambush, Keiji had changed the group into Phantom Crushers with the newly founded Phantom Liquid and prepared a bottle made from Nebula Gas to extract all the Hazard Levels of the Riders, so none of them could transform, with Gentoku as the first victim and the latter being Sento and Ryuga. After Keiji obtained the Build Driver and the Hazard Trigger, he killed Simon as he no longer needed him. Then, he got an information that the Hokuto Three Crows alongside Grease were still able to transform because their Hazard Level couldn't be absorbed, unknowingly that Kazumi and his friends had taken the Phantom Liquid unintentionally by taking a bath on its source spot. Keiji was interested in this and faced the Three Crows when he targeted Misora, yet he didn't know that Misora no longer has Vernage within her. By becoming Metal Build, he easily defeated the Three Crows alongside Grease despite his late arrival and took Misora with her, not before he told Kazumi to bring him the White Pandora Panel.

Later, he had Kazumi come with the White Panel and faced Kazumi's Grease Blizzard and was defeated. However, Keiji used an underhand method on calling a Phantom Crusher to hit Grease from the back. He took the White Panel and absorbed it alongside a Phantom Crusher that was close to him, becoming Phantom Build. As Phantom Build, Keiji gained an upper hand, even when Kazumi later gained the power-up from Ryuga to become Grease Perfect Kingdom, regardless how Kazumi felt pity on him for what happened in the previous world, feeling alone.

During the last moment of their fight, Keiji underestimated Kazumi's determination by mocking him as a weakling who relies on the others, while himself, with the White Pandora Panel, had become the strongest. The provocation angered Kazumi to the point of raising his Hazard Level and made him able to use the true potential of Perfect Kingdom. With the complete defeat from Kazumi's Perfect Kingdom Finish, Keiji mourned by asking how Kazumi got stronger, which Kazumi replying that Keiji had nothing to fight for, much to his dismay as he died by turning into a particle light.

Phantom Build is a playable character in Kamen Rider Buttobasoul.

Personality

Keiji Uraga is a power hungry man and will use any method to achieve his goals, much like any higher ups of Faust during the previous world. For example, he coldheartedly shoots Simon Marcus to death when he reveals to betray him and take over as the leader of Downfall.

He is very sensitive to be called either number two or being inferior to the one he faced as it would drive him mad, albeit he didn't show his anger brightly. Upon utilizing his plans, Keiji is calm and cautious, and whenever his plans worked splendidly, he would smirk in satisfaction before he reaches his final goals.

When his plans didn't work, however, he loses his cool to a degree, going as far to kill the Downfall member who brought him the fake Last White Pandora Panel.

Other negative traits include being extremely arrogant, openly doubting the ideals of his enemies. He told Misora that heroes are just mere fantasies, and even mocks Kazumi's bonds with his comrades. This worsens when he merges with the Last White Pandora Panel to become Phantom Build, along with increased aggression as well.

All of this proves to be Keiji's fatal flaw, with him being defeated by Grease Perfect in the end. Even when he was vanishing, he still doesn't understand why he lost against him.

Powers and Abilities

  • High Hazard Level: Because of how extreme Lost Smash experimentation is compared to regular experimentation, Keiji has developed a high Hazard level, allowing him to utilize a Build Driver and bear the power of the Hazard Trigger.

Weaknesses

  • Superiority Complex: Much like any higher up villains and Blood Tribes, Keiji has a superiority complex and is shown to be completely annoyed to be called number two. He can also be extremely arrogant, and even aggressive when someone mocks him or doubts his ideals, as shown when he was talking with Misora, and during his fight against Grease Blizzard, which the latter got punched heavily on the floor several times and got thrown out of a building through the wall in return.

Keiji transforms into Kamen Rider Metal Build (仮面ライダーメタルビルド Kamen Raidā Metaru Birudo) by using the Metal TankTank Fullbottles in the Build Driver with the Hazard Trigger attached. Due to using two abiotic Fullbottles, Metal Build is incredibly durable and much more powerful than Build's normal forms. Keiji doesn't go berserk in this form, as he uses two identical Fullbottles in the same fashion as the FullFull RabbitTank Bottle.

  • Build Driver finishers:
    • Hazard Attack (ハザードアタック Hazādo Atakku): Metal Build jumps into the air before crashing into the target with a double knee drop. He then creates an energy tank tread that grinds the enemy into the ground.
    • Hazard Finish (ハザードフィニッシュ Hazādo Finisshu): Metal Build performs a roundhouse kick motion towards the opponent, creating a tank track that flies into the target and grinds against them, acting like a chainsaw. This attack can strike multiple opponents.
