Bird Dopant (バード・ドーパント Bādo Dōpanto) is the Dopant form assumed when one uses the Bird Gaia Memory. [1]



Akane Egusa (江草 茜 Egusa Akane) was a middle school girl selected by Saeko Sonozaki to test the limits of one of the newest Gaia Memories: the Bird Memory. In addition to the fact that no one under the age of 20 is allowed to use a Gaia Memory, the Bird Memory could also be used by those without a Living Connector and it has an addictive side effect.

When Akane ran away from home, her friend Touma Fujikawa (藤川 統馬 Fujikawa Tōma) was the first to test the true powers of the Bird Memory out and decided to use it for fun with friends Yuichi Kanamura (金村有一 Kanamura Yūichi) and Yayoi Kubota (久保田 弥生 Kubota Yayoi) until Touma decided to use it to attack people as the Bird Dopant (バード・ドーパント Bādo Dōpanto). They were stopped by Kamen Rider Double, and the two boys were taken into the hospital after suffering from some of the negative side effects of using a Gaia Memory without a Living Connector.

Later, Akane was overpowered by withdrawal from the Bird Memory and attacked Philip who got in her way of obtaining it. Consumed completely by the Gaia Memory, Akane was able to access the Bird Dopant's Strengthened Form (強化態 Kyōkatai), only to be defeated after the Nasca Dopant assisted Kamen Rider Double in finding the Bird Dopant's weak spot for a direct strike on the Bird Memory by means of CycloneTrigger's Trigger Bat Shooting Maximum Drive.
