Kamen Rider OOO

The year is 2021 and the world is in a state of chaos and fear. The ancient king OOO has come back to life after 800 years of dormancy. Eiji Hino returns to Japan, believing he has at last found the means to revive the Greeed Ankh.

Leading an expedition in Germany, Kougami unseals the resting place of one of the alchemists that created the Core Medals in an effort to retrieve a set of lost Medals. However, upon the seal being undone, millions of Cell Medals erupt into a tower while creating a magical barrier that causes parts of Japan to flip over. As the alchemist reveals her plans to become a new OOO, Eiji and his friends are thrown into the past and must find their way back home and stop the alchemist before she destroys the world.

An enemy is caught off guard when the black Core Medals appear and combine with the Gaia Memory into the giant Kamen Rider Core. Kamen Rider Core begins to destroy everything nearby as Kamen Riders OOO and W team up to fight the enemy.

Eiji and Ankh team up with Kotarou and Momotaros as they travel back in time to stop the Imagin. But Ankh's desire to obtain Core Medals while in the past sets off a chain of events that alters the history of the Riders and the world.

College student and motorcycle enthusiast Takeshi Hongo is abducted by the evil organization Shocker and converted into a cyborg as part of their plans for world domination. Before they can brainwash him to do their bidding, he escapes and uses his new enhanced abilities as Kamen Rider to wage a one-man war against Shocker.
