|This article is about a/an Dopant identity in Kamen Rider W.|
Through the use of the Eyes Memory, the user can enforce their will on others. The Eyes Dopant is able to counterattack by detecting the opponent's next move and brand the Quarks with an eye marking on their foreheads that kill them should they try to escape. However, it was unable to read Katsumi's movements as Kamen Rider Eternal. He is also able to communicate through others that are branded with the eye, use large floating eyeballs to create an explosion on what they look at, and summon a whole mass of eyeballs to swarm an opponent.
- Main article: Doctor Prospect
The main user of the Eyes Memory was Doctor Prospect (ドクター・プロスペクト Dokutā Purosupekuto), a Foundation X scientist who was studying the use of psychic ability and created an army of psychic-powered soldiers known as Quarks (クオークス Kuōkusu). In his fight with Katsumi Daido as Kamen Rider Eternal, he manages to kill all of the Quarks, including Mina as it seemed at the time, which enrages Daido and makes him go mad, killing Doctor Prospect by destroying his Gaia Memory and leaving him victim to its psychic killing effect.
