Gene Dopant

The Gene Dopant appeared in 2010 TV series called Kamen Rider W. Gene Dopant (ジーン・ドーパント Jīn Dōpanto) is the Dopant form assumed when one uses the Gene Gaia Memory.

The main user of the Gene Memory was Toru Kawai (川相 透Kawai Tōru), an extremely shy independent film director. Using his power, he made his magnum opus on his own and then tricked theater goers into an empty room to sit through the 7-hour uncompleted film. After being easily defeated, Akiko decides to rehabilitate him by taking control of the movie's production, while trying to hook him up with its star Ai Nijimura who he impersonated beforehand, but this only upsets Toru due to Ai's character being rewritten from the dark figure as originally intended. However, after being used by Wakana to fuse the Gaia Progressor into her body and Akiko beating sense into him, Toru finally speaks his mind. Soon after, Toru gives up the Gene Memory, which is crushed to bits by Kamen Rider Double CycloneJokerXtreme, and begins working on the movie in his own way with Ai.

Powers and Abilities
As Gene Dopant, the user is able to use the DNA Mixer (ＤＮＡミキサー DNA Mikisā) on their right arm to alter the genetic makeup of anything they touch.
