True Gaia Memory

A Gaia Memory (ガイアメモリ Gaia Memori) is a mysterious device resembling a USB flash drive that contains all of the Earth's knowledge of what it represents. This enables its user to become a Dopant or Kamen Rider whose powers and skills relating to that aspect. Gaia Memories are distributed to the citizens of Futo via the black market by Museum, an underground organization headed by the Sonozaki Family that hopes to use the data collected from the Dopants they create to orchestrate a second Gaia Impact. Every Gaia Memory is adorned with the first letter of its name, stylized to reflect the powers it imbues on its user.

In order to transform into a Dopant, the Gaia Memory is first inserted into a device called the L.C.O.G (Living Connector Setting Operation Gun), also called a Connect Shooter (コネクトシューター Konekuto Shūtā), which then produces a USB port-like tattoo on the user's skin called a Living Connector (生体コネクタ Seitai Konekuta). Whenever the Gaia Memory is pressed onto the Living Connector, it enters the user's body and transforms the user into a Dopant. It is possible to use a Gaia Memory without a Living Connector at the cost of additional side effects, such as severe physical pain after several uses. This direct insertion will eventually drive its user insane from its addictive influence. To avoid this, special belts called Memory Drivers (メモリドライバー Memori Doraibā) have been developed for use by high ranking members of Museum to filter out the side effects of using Gaia Memory. However, this weakens the Dopant visibly, and as such high-ranking Museum members use especially potent Gaia Memories, identified by their golden colors, to compensate. Despite their benefits, there are those who dislike the use of Drivers and rather take the risks than being weakened, such as Doctor Isaka.

Kamen Riders utilize Gaia Memories that have been refined to remove all negative side effects. These Memories can only be used in specialized Memory Driver belts, and have their power channeled through the Driver instead of entering the user's body. They were created by Shroud during her research as Fumine Sonozaki. This refinement has the downside of further weakening the Memories, the full power of which can only be accessed during a Maximum Drive.

To defeat a Dopant, a Kamen Rider has to use a Maximum Drive to eject and destroy the Gaia Memory in what is called a Memory Break (メモリブレイク Memori Bureiku). Stronger Gaia Memories require a direct strike on its location within the Dopant's body to execute a Memory Break. If the Dopant did not use the Memory via a Living Connector, a Memory Break will not occur, but the Gaia Memory will still be ejected from the user's body.

A person's ability to use a Gaia Memory depends on their compatibility with it. A user with high compatibility will be able to access a Memory's full powers, sometimes resulting in a Dopant or Kamen Rider gaining a stronger form. A user with lower compatibility will be weaker and may experience adverse side effects. It also seems that when used over long periods of time, the user will be able to use some of the Gaia Memory's power while untransformed, as hinted to when Ryubee seemed to be able to intimidate others after holding the Terror Memory for at least ten years.

These Gaia Memories used by Philip (Double's right half).

  • Cyclone Memory (サイクロンメモリ Saikuron Memori): Also known as the Windy Memory (風の記憶 Kaze no Kioku), allows the user to move at fast speeds and control the very power of wind, turning them into the Windy Warrior (風の戦士 Kaze no Senshi). When used, half of Kamen Rider Double becomes the green Cyclonic Right Half (旋風の右半身 Senpū no Migi Hanshin). Forms using the Cyclone Memory possess the Windy Stabilizer (ウィンディスタビライザー Windi Sutabiraizā), a silver scarf hanging from the neck.
  • Heat Memory (ヒートメモリ Hīto Memori): Also known as the Hot Memory (熱き記憶 Atsuki Kioku), empowers the user with the element of fire, turning them into the Blazing Warrior (炎の戦士 Honō no Senshi). When used, half of Kamen Rider Double becomes the red Heated Right Half (熱き右半身 Atsuki Migi Hanshin).
  • Luna Memory (ルナメモリ Runa Memori): Also known as the Illusion Memory (幻想の記憶 Gensō no Kioku), allows the user to cast illusions, stretch limbs, and bend gunshots, turning them into the Mysterious Warrior (神秘の戦士 Shinpi no Senshi).

  • Trigger Memory (トリガーメモリ Torigā Memori): Also known as the Sniper Memory (銃撃手の記憶 Jūgekishu no Kioku), turns the user into an expert marksman known as the Gun Warrior (銃戦士 Jū Senshi). When used, half of Kamen Rider Double becomes the blue Sniping Left Half (狙撃手の左半身 Sogekishu no Hidari Hanshin).

Pseudo Memories (ギジメモリ Giji Memori) are artificial Gaia Memories which power the Memory Gadgets, allowing them to switch between Gadget Mode and Live Mode.

  • Stag Memory (スタッグメモリ Sutaggu Memori): Allows the Stag Phone to switch between Cell Phone Mode and Stag Mode.
  • Spider Memory (スパイダーメモリ Supaidā Memori): Allows the Spider Shock to switch between Wrist Watch Mode and Spider Mode.
  • Bat Memory (バットメモリ Batto Memori): Allows the Bat Shot to switch between Digicam Mode and Bat Mode.
  • Frog Memory (フロッグメモリ Furoggu Memori): Allows the Frog Pod to switch between Speaker Mode and Frog Mode.
  • Denden Memory (デンデンメモリ Denden Memori): Allows the Denden Sensor to switch between Goggle Mode and Denden Mode.

  • Fang Memory (ファングメモリ Fangu Memori): Also known as the Fanged Memory (牙の記憶 Kiba no Kioku), it is a special Gaia Memory used with the Joker Memory by Double to transform into FangJoker. It was created to protect Philip and act on his orders. It can change between its Live Mode (ライブモード Raibu Mōdo), which resembles a Dromaeosaurid, and its Memory Mode (メモリモード Memori Mōdo), the top of which resembles a dinosaur's head. When used, half of Kamen Rider Double becomes the white Fanged Right Half (牙の右半身 Kiba no Migi Hanshin) while altering the left half to match its spiked design. Unlike other forms of Double, this transformation is initiated by Phillip and the process causes Shotaro to fall unconscious and transfer his mind until transformation is undone
  • Xtreme Memory (エクストリームメモリ Ekustorīmu Memori): A special bird-like Gaia Memory used by Double to transform into CycloneJokerXtreme. It can change from Live Mode (ライブモード Raibu Mōdo) to Memory Mode (メモリモード Memori Mōdo) in order to slide onto the Double Driver. The Xtreme Memory's powers come directly from the true Gaia Memory. When Philip dissolves after his final battle as Kamen Rider Double, the Xtreme Memory, which holds the data of his mind and body, does as well. However, after Wakana sacrifices her life, she brings back the Xtreme Memory, which holds Philip's body until his physical form is restored.

  • Prism Memory (プリズムメモリ Purizumu Memori): Powers the Prism Bicker. It serves as a conduit for other Gaia Memory powers and can combine the powers of four Maximum Drives into one.
  • Shippu Memory (疾風メモリー Shippū Memorī): A version of the Cyclone Memory created and used within the Nightmare Dopant’s dream world.
  • Kirifuda Memory (切札メモリー Kirifuda Memorī): A version of the Joker Memory created and used within the Nightmare Dopant’s dream world.


  • Accel (アクセルメモリ Akuseru Memori): Also known as the Acceleration Memory (加速の記憶 Kasoku no Kioku), allows Kamen Rider Accel to transform into his default form.
  • The Trial Memory (トライアルメモリ Toraiaru Memori): Also known as the Challenge Memory (挑戦の記憶 Chōsen no Kioku), allows Kamen Rider Accel to transform into Accel Trial. It is used in its Memory Mode (メモリモード Memori Mōdo) for transformation. The transformation is complete once the light on the Trans-Signal (トランスシグナル Toransu Shigunaru) flashes red, then yellow twice, then finally blue, signifying a 3 second countdown. While in its Maximum Mode (マキシマムモード Makishimamu Mōdo), it allows Accel Trial to perform his Maximum Drive. Once the Maximum Switch (マキシマムスイッチ Makishimamu Suitchi) button is pressed, Accel has ten seconds to perform as many attacks as possible before pressing the Maximum Switch again to finish the Maximum Drive. If the Maximum Switch is not pressed within the time allotted, the Maximum Drive fails and Accel's transformation is forcibly cancelled.

  • Engine Memory (エンジンメモリ Enjin Memori): Powers the Engine Blade . It is not a true Gaia Memory, however, and its powers are linked to the Accel Memory. It empowers the Engine Blade with several abilities, each based on a different type of engine: Steam (スチーム Suchīmu), which creates a wave of hot steam; Jet (ジェット Jetto), which allows the Engine Blade to execute heated slashes or fire an energy projectile; and Electric (エレクトリック Erekutorikku), which allows the Engine Blade to perform electrically charged slashes or fire a bolt of electricity.
  • Beetle Memory (ビートルメモリ Bītoru Memori): The Beetle Memory allows the Beetle Phone Memory Gadget to switch between its Cell Phone Mode and its Beetle Mode.

  • Cyclone Memory (サイクロンメモリ Saikuron Memori): Ryu was briefly lent the Cyclone Memory by Philip to battle the Weather Dopant. When inserted into the Engine Blade, it allows Kamen Rider Accel to perform a wind-powered Maximum Drive.


  • Skull Memory (スカルメモリ Sukaru Memori): Also known as the Skeleton Memory (骸骨の記憶 Gaikotsu no Kioku), allows Kamen Rider SKull to transform.

  • T2 Joker Memory (T2ジョーカーメモリ Tī Tsū Jōkā Memori): Used by Kamen Rider Joker to transform. This Memory is later destroyed with the other 25 T2 Gaia Memories during the battle with NEVER, with the Lost Driver being lost as well.
  • Joker Memory (ジョーカーメモリ Jōkā Memori): Following the loss of Philip, Shotaro uses his normal Joker Memory with a Lost Driver left by Philip to transform into Kamen Rider Joker.

  • Eternal Memory (エターナルメモリ Etānaru Memori): Used by Kamen Rider Eternal to transform. A user with poor compatibility will only be able to access Eternal's Red Flare form, while a user with strong compatibility can access Blue Flare. It was abandoned by Daido in favor of the stronger T2 Eternal Memory.
  • T2 Eternal Memory (T2エターナルメモリ Tī Tsū Etānaru Memori): Used by Kamen Rider Eternal to transform.



T2 Gaia Memories (T2ガイアメモリ Tī Tsū Gaia Memori, short for "Type Two") are next generation Gaia Memories created by Foundation X using Shroud's research before she left the Museum and later stolen by NEVER. They are exclusive to Kamen Rider Double Forever: A to Z/The Gaia Memories of Fate.

There were 26 T2 Gaia Memories, one for each letter in the alphabet. Unlike other refined Gaia Memories, they have blue plugs instead of silver or gold ones. They are capable of transforming someone into a Dopant without a living connector and not cause the side effects associated with previous Memories. T2 Gaia Memories can also be used with a Lost Driver to transform into a Kamen Rider. T2 Gaia Memories also seem to have a level sentience, as they were seen seeking out compatible users. T2 Memories are also implied to be stronger than their T1 counterparts. Unlike the previous Gaia Memories, T2 Gaia Memories could not be destroyed with a normal Maximum Drive, which only results in the Memory being ejected from the user.

The "Dopants" produced with these Memories are simply outrageous outfits instead of monster costumes.

  • Bean Memory (ビーンメモリ Bīn Memori): This Memory was seen in a flashback in the TV series of a Museum lab as part of an experiment to test Gaia Memories. In the net movie, Jinno claims that the original Bean Memory was replaced by the producer for being too horrid, then proceeds to test it on Makura, transforming him into the Bean Dopant ( Bīn Dōpanto). Jinno then eats the beans that grew on his assistant. The Doctor is Happy About B/Now, In the Mumbling

The Comedy of Y/The Man Searching for Curry
  • UFO Memory: Jinno tries testing it on Makura, but Makura fights back and it ends up touching a ramen deliveryman, turning him not so much into the UFO Dopant as an actual small flying saucer spacecraft, which they send off to explore space for Museum. The U is a Mystery!/Roundelay

A new batch of special Gaia Memories was released in 2013, more or less two years since Bandai stopped releasing Gaia Memories in any form — DX Candy Toy, Gashapon.

Wizard

The Gaia Memories, along with the other Rider Powers, were stolen from Double by Amadum in the world within the Magic Stone, who explained that they were already his due to the Riders' powers being from the same source as evil. However, the power was soon returned thanks to the appearance of Kamen Rider Gaim, with the return of the Memories immediately transforming Double into CycloneJokerXtreme. Neverending Story

Portrayal

The voice of the Gaia Memories is provided by Fumihiko Tachiki (立木 文彦 Tachiki Fumihiko), who is also the narrator of W.

Notes

  • Astroswitches, Lockseeds, and Rider Gashats take cues from Gaia Memories in design and function:
    • Both Rider Gashats and Gaia Memories are removed from the main belt and inserted into a secondary slot to activate their belt finishers.
    • All four of these devices can be inserted into weapons to activate weapon finishers.
    • Gaia Memories, Lockseeds, and Rider Gashats all have buttons that, when pressed, declare the name of the individual device. Astroswitches declare their name when inserted into the Fourze Driver.
    • The Double Driver and Gamer Driver both can utilize two Memories/Gashats at once, and there are Memories/Gashats that take up both slots.
    • They are all used by villains. Dopants use Memories to transform, Zodiarts use Zodiarts Switches to transform, Inves use Lockseeds to become more powerful, and Bugsters are born from games that have been made into Gashats, as well as the Collabos Bugsters using Gashats directly to gain armor.
    • Particularly powerful instances are much larger and sometimes come with unique functionality, such as the Fang Memory which transforms into a dinosaur and has its own Sengoku Driver-like finishers, the N and S Magnet Switches that combine into the NS MagPhone and can be used as gun triggers in Magnet States, the Kiwami Lockseed which connects to the Kachidoki Lockseed and can be turned to summon weapons, and the Gashat Gear Dual which contains two games, functions on its own, and can be used in the Gamer Driver for a super form.
  • The creation of Gaia Memory is very similar to the Materia from Final Fantasy VII, since both items are created from the knowledge from their respective planets.
  • The Joker Memory is used after the series to represent Kamen Rider Double's power instead of both it and the Cyclone Memory as seen in Kamen Rider × Kamen Rider Gaim & Wizard: The Fateful Sengoku Movie Battle and Kamen Rider Ghost: Legendary! Riders' Souls!.
