Shinkuro Isaka



The Weather Dopant is a powerful enemy in Kamen Rider Double and the archenemy of Kamen Rider Accel.

Shinkuro Isaka
Shinkuro Isaka (井坂 深紅郎, Isaka Shinkurō?) is the head physician at the Isaka Medical Clinic (井坂内科医院, Isaka Naika Iin?). Ten years ago, finding no meaning in his life, he encountered Ryubee Sonozaki attacking a group of people as the Terror Dopant. This made Isaka seek to get the Terror Memory for himself, experimenting on himself with several Gaia Memories with various Living Connectors on his body before he settles on one. After his identity is discovered during his failed attempt to add the Invisible Memory to his arsenal, Isaka takes refuge in the Sonozaki estate where he convinces Saeko to take out her father so she can control the Museum and he can get the Terror Memory. Though he originally sees Saeko as merely one of his pawns, he admits to having developed feelings for her. During his attempt to absorb the Quetzalcoatlus Memory, the Weather Dopant is finally defeated by Kamen Rider Accel Trial's Machine Gun Spike Maximum Drive, shattering the Weather Memory. Shortly afterwards, Isaka's excessive use of Gaia Memories causes his body to become covered in Living Connectors that dissolve him away into nothingness as he tells the Kamen Riders that Shroud will be their end.

As the Weather Dopant (ウェザー・ドーパント, Wezā Dōpanto?), he is armed with the whip-like Weather Mine (ウェザーマイン, Wezā Main?) and control over the elements: intense sunlight, heavy rain, lightning, tornadoes, and freezing snow. He originally tested these abilities in a series of murders which include Ryu Terui's family, to whom he is only known as the man with the W Memory (Ｗ（ダブリュー）のメモリを持つ男, Daburyū no Memori o motsu otoko?). Isaka does not use a Gaia Driver, as he feels it only limits the power of Gaia Memories, and he is unaffected by their corruption as he is already intensely psychotic. The Weather Dopant can also withstand Maximum Drives, as he has augmented the Weather Memory with other Gaia Memories' powers. This skill and his knowledge of Dopant physiology makes him an ally to the Museum.
