Kaisei Mogami is the main antagonist of the 2017 film Kamen Rider Heisei Generations FINAL: Build & Ex-Aid with Legend Riders. He is a scientist of Namba Heavy Industries Ltd. from the World of Build working alongside his alternate counterpart, a Foundation X researcher from the World of Ex-Aid, to destroy both dimensions by merging both of them together.

He was portrayed by Kenji Ohtsuki.

History

Origin

Kaisei Mogami originally worked at the Touto Institute of Advanced Matter Physics where he discovered the Bugster Virus inside the Skywall. Theorizing that it came from a parallel world, Kaisei began working on a dimension bridging machine called the Enigma alongside Takumi Katsuragi.

When the Touto government did not approve his budget for the project Kaisei sought backing from the weapons manufacturing company known as Namba Heavy Industries Ltd.. While working at the company, Kaisei also developed a form of the Bugster Virus infused with Nebula Gas and created the Kaiser system.

However, Katsuragi discovered that Kaisei intended to use the Enigma device not just to create a bridge between the two dimensions but to merge them together and destroy them. Thus, Katsuragi quit working on the project and sabotaged the Kaiser system.

Completing the Enigma

2 years later, Kaisei put the finishing touches on the Enigma and began initiating the final stages of his plan to become ruler of both dimensions alongside his Ex-Aid counterpart. He set his Nebula Bugsters loose in order to lure out Build so he could claim the Doctor and Game Fullbottles from him. He was pursued by Cross-Z, but Kaisei managed to send him to the World of Build using his Enigma device.

His Ex-Aid counterpart meanwhile also set the Nebula Bugsters loose in order to empower his own Enigma machine. He then activates the machine and brings the Build Earth to the World of Ex-Aid.

Eventually, Kaisei as Left Kaiser merged with Ex-Aid Kaisei as Right Kaiser to become Bi-Kaiser as the final step of his plan to become ruler of both worlds. However, his plan was foiled when Build activated the Enigma early, preventing it from being able to converge the worlds on time. Bikaiser was then defeated by Kamen Riders Build and Ex-Aid.

    • Grudge Signal - Kaiser's output regulator. When the angry emotions of the transformant exceed a certain level, the chest strengthening device "Nebula Generator" is activated at high speed, providing combat power that is difficult to control.
    • Air Face Duct - Kaiser's intake and exhaust system. It has the role of removing harmful substances when taking in the surrounding air inside. It is also possible to discharge toxic gas.
    • KA Side Blade - Kaiser's data collection device. It is possible to aggregate battle data in real time and accurately grasp the abilities of yourself and the enemy. It also manages the condition of the whole body, and if there is a damaged part, it automatically performs emergency repair.
    • Dusk Seeker Eye - Kaiser's visual sensor. It is a high-sensitivity sensor with a night-vision function, and can instantly detect moving object reactions and heat source reactions. It can also detect chemicals in the air and look for traces of enemies.
    • KA Face Guard - A protective device that protects Kaiser's head. It is possible to minimize damage by emitting waves that attenuate the enemy's energy attack.
  • Cog Chest Armor - Robust armor that protects Kaiser's chest. Equipped with a device "Nebula Generator" that uses special steam to strengthen the fighting ability, it is possible to speed up all movements of itself for a certain period of time and increase the power of attacks.
  • Punishment Arm - Kaiser's arm. It has both power and speed, and is good at high-powered elbow strikes and continuous punches.
  • Dominate Gloves - Reinforced gloves that cover Kaiser's fist. It has a shape specialized for fighting attacks, and is good at continuous thrusting using a claw with a sharp fingertip.
  • Punishment Leg - Kaiser's legs. It has both power and speed, and is good at high-power knee kicks and continuous kicks.

  • Gear Steam Shoulder - Armor that protects Kaiser's shoulders. Optimize the movement of the arm to improve the attack accuracy. It is also possible to disperse the appearance by spraying colored gas through the gaps in the armor.
  • KA Unlimited Suit - Kaiser's shock-resistant bodysuit. At the same time as protecting the transformant from combat damage, it is possible to release the physical limiter and bring out the hidden physical ability.
  • Gear Torque Gauntlet - An attack device attached to Kaiser's arm. It is possible to generate and inject a gear-type energy cutter. The control unit of the huge device "Enigma" that interferes with the parallel world is also incorporated.
  • Metal Knee Bat - Armor that protects Kaiser's knees. Optimize leg movements to improve exercise speed.
