Dr. Shinigami is the second Shocker commander to appear in the Japanese TV series Kamen Rider.


Summoned from Switzerland, Dr. Shinigami took command after Kamen Rider 2 destroyed Colonel Zol. He is mostly seen in his cape, holding a wand. He is able to transform into Ikadevil, a squid monster. In episode 68, he kidnapped Tobei Tachibana and forced him to train him so he can destroy Kamen Rider 1. As a result, Tobei discovers his weak spot: Ikadevil's head! When Kamen Rider 1 came to challenge him, Dr. Shinigami discards his cape and becomes Ikadevil to deal with Ichigo once and for all. Kamen Rider 1 overpowers Ikadevil by giving a Rider Chop on his head, and finishing him off with Tailspin Shoot. He is briefly brought back to life for a Destron operation, thinking he was to replace Doktor G, along with the other Shocker and Gel-Shocker officers. He along with the other resurrected officers is killed when the Destron base they are in self-destructs.

Due to a change in history caused by Ankh leaving a O Medal behind in 1971, Shocker achieved its goal of world dominion with the Shocker Greeed which defeated the Double Riders, and new members from the various groups that would had manifested in the normal timeline after Shocker's destruction. Ikadevil was among the many villains who were part of the this alliance. When the riders united against Shocker, he along with Ganikomol and Garagaranda was destroyed by Kamen Riders Den-O and New Den-O.
