"I am a warrior who feeds on the dark hearts of people, I turn sadness into the power of hate. My name is Kamen Rider Core!"
―Kamen Rider Core introducing himself[src]

Kamen Rider Core (仮面ライダーコア Kamen Raidā Koa) is the main antagonist in the final portion (Movie War Core) of the film, Kamen Rider × Kamen Rider OOO & W feat. Skull: Movie War Core.

Character History

Core is purely an energy-based Rider. He was created from the Sasori, Kani, and Ebi Core Medals, which appeared to house his consciousness, merging with the Memory Memory which held the memories of all of the Kamen Riders and the True Gaia Memory, thanks to the Pteradon Yummy gathering them. Because of these memories being housed in him, Core possessed various traits from previous Riders. The main source of his power came from a crystallized form of Earth's energy. The crystal was destroyed by Double CycloneJokerXtreme's Bicker Charge Break and OOO's OOO Bash. This, however, did not drain his powers completely, as Double and OOO had believed. Instead, it only removed some of his power, and in his fury he stopped (albeit briefly) OOO from assuming Tajadol Combo. However, this was only temporary. Core was then slain at the hands of Double CycloneJokerGoldXtreme's Golden Extreme & OOO Tajadol Combo's Prominence Drop.


Being an amalgamation of the memories of all previous Riders and their battles, Core believed himself to be the most powerful Rider, and being for that matter, in existence. He sought to use the power he had to rule over the rest of the Earth. He was arrogant, calling Double and OOO losers and worms. He responded with shock and fury when Double and OOO told him that he was only a fraud that was imagining himself as having done accomplishments the other Riders did and how he was nothing compared to true Kamen Riders, who protected the innocent even when it interfered with their own personal lives.

Core Bike State

Core can turn his lower body into a motorcycle called the Bike State (バイク形態 Baiku Keitai), reminiscent of Showa Era Rider Machines, to increase his speed. Core's Bike Mode also proved to be durable enough to smash through dense rocks as if they were nothing.

Concept Art

Kamen Rider Core was designed by Katsuya Terada (寺田 克也 Terada Katsuya).


  • He is the first entirely CG Kamen Rider (all of the other Kamen Riders were actors and suit actors with special effects added to their transformations and finishing attacks) albeit more similar to a Daikaiju than a Kamen Rider.
    • The first instance of a human-sized CG Rider would occur in the form of Build RabbitDragon.
      • It was less than a year after that that a similar concept to Kamen Rider Core was created in the form of Another Kuuga and Another 1.
  • He is the second Rider that can change into a bike, the first being Kamen Rider Accel.
  • He can be categorized as both a W Rider and an OOO Rider, due to him being made from a Gaia Memory and a set of Core Medals.
  • Kamen Rider Core greatly resembles Kamen Rider 1.
    • This is presumably because Kamen Rider 1 was the original and therefore the symbol for the Kamen Rider series.
  • He is also the fifth Kamen Rider that is gigantic aside from Kamen Riders 1, J, Arc, and Decade (Jumbo Formation).
