Doctor Death/Ikadevil (死神博士/イカデビル Shinigami Hakase/Ikadebiru, 40-52, Rider vs Shocker, 61, 63 & 68, V3 27 & 28 & Decade: All Riders vs Great-Shocker, Let's Go Kamen Riders) is an executive member of Shocker from the Switzerland branch.


Kamen Rider

Before joining Shocker, Doctor Death was known as Ivan Tawanovitch a half-Japanese, half-Russian citizen who was given the title 'Death' 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.

Death 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 become 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, Death finds Mao supposedly dead in South America, but Mao had actually just transcended his Earthly body. Mao then asks Death to join him in his goal to take over the world offering to help save his sister.[1]

Death began working in modified human research in Europe, but his creations were destroyed by Kamen Rider One whose constant interference made the doctor focus on defeating the rider. After Colonel Zol's destruction at the hands of Rider Two, Death takes command of Japan's branch.Deathmatch! Monster Snowman vs. Two Riders

He faces Rider Two in Japan several times and came close to success, but with the help of the original Rider, the Double Riders stopped his plans. Eventually, he left Japan to South America only to be followed by Rider Two.My Name is Mysterious Birdman Gilgalass

Death then goes through a reconstruction process to become Squidevil, a squid monster with the ability to use his tentacles as whips and a pincer claw for his left hand. However, Death predicts he will die in battle.[1] He returns to Japan and works alongside Ambassador Hell to take down Takeshi Hongo.Monster Catfishgiller's Electric Hell

Hongo confronts a transformed Death as Squidevil when he's ambushed while testing the New Cyclone. Frustrated by Rider One's continuous interferences, Death decides to attack him personally by kidnapping Tobei Tachibana and forcing him to train him to crush Rider One. However, that just leads to Tobei noticing Squidevil's weak point, his head.

Finally, Death challenges Takeshi Hongo to a duel. When they meet, Death discards his cape and transforms into his cyborg form, Squidevil, revealing his identity to Hongo. Shocker Combatants take care of Kazuya Taki while he fights Hongo. At first, Squidevil has the upper hand, but with guidance from Tobei, Rider One manages to overpower Squidevil and weaken him with a Rider Chop aimed at his weak point near the neck before finishing him off with his Rider Drill Shoot.Doctor Death, the True Meaning of Terror?

He died with the other revived commanders when Destron's base accidentally self-destructed.

Let's Go Kamen Riders

40th Ikadevil & Garagaranda

Due to a change in history caused by Ankh leaving an O Medal behind in 1971, Shocker created the Shocker Greeed. The Double Riders learn about Shocker's plan and attempt to replace the medal with a tracker device to find their headquarters. However, they had merely secured another fake medal and were ambushed when attacking Shocker, facing a large army of resurrected monsters, which included the recently defeated Squidevil and Garagaranda. These troops eventually manage to overwhelm and capture the Riders, while their allies escaped. In the present, Squidevil continued as a Shocker member even as it expanded to include members from other groups that would have been separate organizations in the original timeline, alongside making a huge alliance to lead under its banner the organizations that did appear. When the Riders returned as people's belief in justice partially restored the timeline, Squidevil along with Ganikomol and Garagaranda was destroyed by Kamen Rider Den-O Climax Form's Boistous Slash and Kamen Rider New Den-O's Counter Slash.

Doctor Death in Kamen Rider Decade

In Kamen Rider Decade: All Riders vs. Dai-Shocker, a new version of Doctor Death appeared, under the guise of Eijiro Hikari as a Dai-Shocker commander, using cape once again to assume transformations. Like in Kamen Rider, Death has the ability to assume his cyborg form, Squidevil. In the film, Squidevil 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 to have no memories of being Death.

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

In the manga adaptation, Eijiro's transformation into Doctor Death was played for real. Natsumi was more visibly upset and Eijiro didn't return at the end after Death was destroyed. Death also didn't transform into Squidevil neither did Ambassador Hell transform into Garagaranda.
