Dopants
The Dopants are normal humans who use Gaia Memories which have the knowledge of everything on the Earth. The Sonozaki Family uses a strange temple underneath their mansion to access the Gaia Memory. They then sell these to the highest bidder or to common criminals, both types used as guinea pigs to study the Gaia Memories as part of the Gaia Impact project. The name comes from the English words "dopant" and "doping". 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. It makes a USB port-like tattoo called a Living Connector and when a Gaia Memory is pressed onto the Living Connector, it transforms the user into a Dopant. Using a Gaia Memory without a Living Connector has the fatal side effects and a Memory Break won't occur but the Memory will still be ejected.

Special belts called Memory Drivers were developed for use by high ranking members of the Museum to filter out side effects. This weakens the Dopant visibly; high-ranking Museum members use some of the strongest Gaia Memories to more than compensate for this weakening. In some cases, a Gaia Memory may be compatible with its user which, in that case, direct insertion won't corrupt the user and may even make the Dopant even stronger.

To defeat a Dopant, a Kamen Rider has to use one of his Maximum Drive, a finishing attack to forcefully eject and destroy the Gaia Memory, resulting in a Memory Break. Evolved Gaia Memories require a direct strike on its location within the Dopant's body to execute the Memory Break without the risk of killing the user. In order to defeat a Dopant that uses a Memory Driver, the belt must be broken in order to defeat the Dopant.

Gaia Impact
The Gaia Impact is an event that was planned by Ryubee Sonozaki to enable all humans to be made one with the Earth, the result of his fear for the certainty of humanity's future due to the extensive extinctions that he studied as a paleontologist and archaeologist. This plan began when his son Raito (Philip) died after falling into the source of the true Gaia Memory and became a data entity and conduit for its powers, enabling the production of the artificial Gaia Memories. After Philip was saved by Sokichi Narumi and Shotaro from the requests of Shroud, the Gaia Impact was halted until Philip could be retrieved. The source was then used to monitor the use of Gaia Memories, collecting their data to prepare for the Gaia Impact.

After Kamen Rider Double accesses his Xtreme form, it enables the Museum to produce the Prototype Organic Information Controlling Organ Body Gaia Progressor for Wakana, enabling her to transform into ClayDoll Xtreme and become the new conduit for the true Gaia Memory. After Ryubee convinces Philip to help with the family's plans once more after Philip discovers that he has died, Philip is thrown into the source of the Gaia Memory once more, dissolving in data that Wakana absorbed until Shotaro stops Ryubee.

After Philip is separated from Wakana through the Xtreme Memory and Ryubee dies, Jun Kazu takes Wakana with the intent to convert her into data in order to upload her to one of the Foundation's satellites and have her kill all life on Earth that is incompatible with Gaia Memories. However, he must wait until her power as ClayDoll Xtreme must resurface; after discovering that Philip's emotions are linked with Wakana's power level, he decides that the only course of action is to kill everyone close to Philip in order to set the plans into motion. This fails when Shotaro rescues Wakana and, in the process, destroys the building and equipment necessary to cause the Gaia Impact. Afterwards, Kazu himself falls to Double, putting an end to his plan for the Gaia Impact for good. Foundation X stops funding Gaia Memory Research and pursuing the Gaia Impact.

After Wakana discovers that Philip has given up his life for her, she decides to modify the Gaia Impact to do what she believes is best for humanity; she decides to sacrifice her existence to bring Philip back so he can protect the Earth with Shotaro as Kamen Rider Double.
