Subsequently it was used by both Shotaro Hidari and Philip to transform into Kamen Rider Double in order to fight against the Museum Corporation.ĭue to having Gaia Memories used retain their physical form when transformed instead of being absorbed, the user is completely shielded from their corrupting effects, at the cost of further weakening the memories' powers when not boosted during a Maximum Drive activation. However it was stolen by Kamen Rider Skull and Shotaro Hidari from the Narumi Detective Office after Philip was rescued from the museum. The Doubledriver was originally created by the Museum to link to Raito, the person who has all the knowledge of the Earth in the form of the Gaia Library.

It was also later shown that the Xtreme Memory can be inserted to further boost the Gaia Memories if the users are compatible enough with the memories and each other. However unlike the Gaia Driver, the Lostdriver and the Acceldriver, which all only have one Memory Slot, the Doubledriver has two Memory Slots that allow two clear Gaia Memories to be inserted and give the user more power. The Doubledriver was inherently based on the Lostdriver and was the third to be built in the series.
