Timeline

A timeline of events in the Kamen Rider Series.

Ancient History

 * 60 milion years ago: The parasitic lifeform Fog Mother arrives on Earth to feed and spawn her offspring, resulting in the extinction of the dinosaurs.
 * 10,000 years ago: The Undead are created by God in the form of the a stone slab called the Monolith, to kill each other in a free-for-all battle royale known as the Battle Fight, with the winner granted a wish to alter the world. The 52 Undead represented 52 different species and battled so they can wish for the species they represent to rule the Earth, while the Joker represented death. While the other Undead were sealed by the Monolith, the winner of that battle was the Human Undead and the world has been populated by humans ever since.
 * Early human civilization: The Gurongi, a mysterious ancient civilization consisting of beings that can transform into monsters to kill people for their ruthless game, which is translated into the Gurongi Language as the "Gegeru", attack their rival civilization the Linto, the original Kuuga defeats the leader of the Gurongi and seals all 200 of the Gurongi away. The Linto's success in defeating the Gurongi was because of the Lords, who had revealed to them how to make Kuuga's equipment.
 * 800 years ago: The Greeed are created from the fifty Core Medals by humans who attempt to create life under the will of the King, the First Kamen Rider OOO, as part of his plan to achieve godhood. Though originally mindless, the five Greeed gained wills of their own after one Medal in each of the five sets was destroyed. They are beings without true life that crave endlessly, cursed with a void in them that can never be filled. They lack proper senses, resulting in bleak sensory input (e.g., colors are washed out, taste is nonexistent, sounds are muffled and distorted), as well as the inability to feel deeper emotions such as love. As such, the four other Greeed became bent on filling the void left in them by consuming everything obsessively in an attempt to experience what humans normally take for granted. However, they and part of Ankh were sealed by the King when the Core Medals consumed him and transformed him into a stone coffin.
