Hybrid Insector

Hybrid Insector is an unofficial dojinshi spin-off manga of the Showa Era Kamen Rider Series by Eiichi Shimizu and Tomohiro Shimoguchi. The manga would only publish nine chapter until Toei gave notice to stop.

Plot
Before the series' start, in the twentieth century Kamen Riders had fought against an evil threat where many friends and family members were lost. However, they were defeated by people with powers and enhancements. With their defeat, the Kamen Riders and anyone similar to them were reduced to being called Hybrid Insectors. Eight years later, the newly named Hybrid Insectors were being hunted down by groups called the Insect Hunters. One member named Akira joined the group because he lost his father because of a Hybrid Insector. What Akira didn't know is, his father himself was a Hybrid Insector who was killed by an Insect Hunter. Encountering one of the originals Shiro Kazami who defeated an army of clones, Akira puts on a belt and himself becomes a Hybrid Insector. Now wanted by the Insect Hunters, Akira reluctantly joins V3 in the battle to bring Kamen Riders back to their former glory and free them from oppression.

Cancellation
When Toei found out about the dojinshi and its popularity without their permission they gave out an order to stop. The manga was forced to stop but nine chapters are stil available in raws and translations.
