Kamen Rider: Memory of Heroez

The Narumi Detective Agency receive an email from a client requesting them to find "Professor Aida" with Shotaro Hidari leaving to investigate the island-based Sector City, once a tourist hotspot until an accident made it uninhabitable while emitting a strange energy. Shotaro meets with Kamen Riders OOO and Zero-One to uncover the mystery behind Aida and stop a Foundation X scientist reviving their old enemies and fallen allies as immortal super soldiers under his control.

• Zeus Dopant (ゼウスドーパント, Zeusu Dōpanto)

The game's main antagonist, a Foundation X scientist who assumed his current form using the Zeus Memory, overseeing Aida's eternal super soldier project using the foundation's research on Gaia Memories, O Medals, and Necro-Overs in hopes of reviving her. He created Sector City's Central Tower to energize the Core Energy, which revives both fallen enemies and allies of both Kamen Riders W and OOO. The tower he created also draws Kamen Rider Zero-One to the prime universe, which might explain why the other cast from Zero-One are not present in the game. Ultimately, he and other Kamen Riders found out that Aida was using them all along. Once Aida had been defeated by Zero-One, OOO, and W, Zeus ultimately join Ankh and Nazca in sacrificing their lives destroying Sector City and foiling Aida's plan.

• Ai (アイ)

An amnesiac artificial intelligence who is stuck inside a floating robot body, serving as the player's navigator before the near end of the game revealing her true identity. She was actually a receptacle of Aida (アイダ), a Foundation X scientist who established the enteral super soldier project before dying in a freak accident. But she transplanted her mind into Ai, initially a support drone for Sector City, manipulating the Kamen Riders and the Zeus Dopant before revealing herself while transferring her mind into Muchiri to achieve immortality as a Greeed. Philip was planning to fix Ai after the crisis is over, but the outcome after Aida was revived inside Muchiri caused him unable to find a way to fix her, despite having had aware of Aida's presence inside Ai from the beginning.

• Muchiri (ムチリ)

A man-made arthropod Greeed created by Zeus to revive Aida with unlimited access to Core Energy, Aida betraying Zeus once obtaining her power before being destroyed with her vessel. Some of the Core Medals that compose Muchiri are taken by Kamen Rider OOO to assume Mukachiri Combo form.
