History

Kamen Rider

Before joining Shocker, Doctor Shinigami was known as Ivan Tawanobicchi, a half-Japanese, half-Russian citizen who was given the title 'Shinigami' due to the deaths of people he met, even if he did not have anything to do with the deaths and 'Doctor' after he graduated from college with a doctorate as a famous researcher.

Shinigami was working with the Nazis during WWII when Japan was allied with them. He was working on a way to make replacement bodies for dying people, one of them was his father but it was a failure. His sister had became ill and after an accident in the arctic her body was frozen. After the war, the doctor traveled the world after hearing rumors of a monk who can bring back the dead. After finding the monk, Chan Mao, in Tibet; the doctor begged the monk to tell him the secret of bringing back the dead. But the monk refused as the doctor because he is too bound to human emotions. A few years later, Shinigami finds Mao supposedly dead in South America, but Mao had actually just transcended his Earthly body. Mao then asks Shinigami to join him in his goal to take over the world offering to help save his sister.

Shinigami began working in modified human research in Europe but his creations were destroyed by Kamen Rider #1 whose constant interference made the doctor focus on defeating the rider. He then goes against Rider #2 in Japan and Brazil but could not defeat him. The doctor then went through the reconstruction process to become Ikadevil but predicted he would die in battle.

After Colonel Zol's destruction at the hands of Rider #2 Shinigami takes command of Japan's branch. When Takeshi Hongo appears to fight him Shinigami discards his cape and transforms into his Inhumanoid form, Ikadevil, a Squid Kaijin with the ability to use his tentacles as whips. Ikadevil had Shocker Soldiers take care of Ichimonji while he fought Hongo. At first Ikadevil had the upper hand, with guidance from Tobei, Rider #1 manages to overpower Ikadevil and weaken him with a Rider Chop before finishing him off with his Rider Tailspin Shoot.

V3

He is briefly brought back to life along with the other Shocker and Gel-Shocker officers to help supervise a far-reaching Destron plot. He speculated about how he had been brought back to replace Doctor G, only to learn that he was there just for a new operation. He along with the other resurrected officers is killed when the Destron base they are in self-destructs.

Let's Go Kamen Riders

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. OOO, Den-O, All Riders: Let's Go Kamen Riders

Kamen Rider Decade

All Riders vs. Dai-Shocker

In Kamen Rider Decade: All Riders vs. Dai-Shocker, a new version of Doctor Shinigami appeared, under the guise of Eijiro Hikari as a Dai-Shocker commander, using cape once again to assume transformations. Like in Kamen Rider, Shinigami has the ability to assume his Inhumanoid form, Ikadevil. In the film Ikadevil now has the ability to shoot flaming squids at his opponents called Ika Missiles. He is destroyed in the final battle against the Riders by Kamen Rider Decade, Kamen Rider Diend, and Momotaros using the Final Form Rides of Kiva, Blade, and Faiz, telling the Riders that he'll be seeing them again. Despite this, Ejiro lives having no memories of being Shinigami.

In spite of his different appearance, his official profiles originally just gave him the story of the Shinigami from the original Kamen Rider series as his backstory. However, in Movie War 2010, the true nature of the new Shinigami was revealed as something else.

Final Chapter

In Kamen Rider Decade: Final Chapter, Ejiro regains his memories after seeing a squid dish presented to him by Narutaki. Through the black Shinigami Hakase Gaia Memory, given to him by Ryubee Sonozaki, Ejiro becomes Super Doctor Shinigami, the leader of Super Shocker. In the movie he revives the Neo Organism to destroy Decade. However, Super Doctor Shinigami reverts back to Eijiro as the Memory ejects out of him caused by Kamen Rider Double HeatMetal's HardMammother Maximum Drive and he is saved by Natsumi in her Kamen Rider Kiva-la form.

In spite of his different appearance, his official profiles originally just gave him the story of the Shinigami from the original Kamen Rider series as his backstory. However, in Movie War 2010, the true nature of the new Shinigami was revealed as something else.
