In the Kamen Rider continuity, The OverLord created the ancestors of humans over 30,000 years ago along with the Lords as their protectors, then humans were declared the dominant species in Earth through the Undead's Battle Royale approximately 10,000 years ago, after the founder of the Human Race defeated the Joker and was declared the last Undead.
Afterwards, Humans had made their own civilization, but were divided by their beliefs. One tribe known at that time as the Gurongi, who transformed into monstrous beings after finding a magical stone from the heavens and used it to wage war on the other tribes. While the other tribe, who lived peacefully, were known as the Linto. Being a peaceful tribe, they never had a need for warriors. In fear of their tribe being eradicated by the Gurongi, the village shamans sought the help of the Lords, who helped them by selecting Riku to become their tribe's defender. Although the Linto's champion defeated the Gurongi, the Linto's lives were changed. Humans became as aggressive as the Gurongi and sought things to satisfy their desires.
About 800 years before a certain individual met a certain floating arm, a group of alchemists were instructed by their king to devise a means to harness different attributes from each living animal on the planet, thus creating the Core Medals. After these Medals became sentient beings called Greeed, the king tried to defeat them in order to acquire their power. After defeating the Greeed, the king tried to assimilate them into his body. Ultimately, the process backfired and the OOO driver sealed the medals with the Greeed and the king inside a sealed sarcophagus.
During the Heisei period, other races that were similar to Humans emerged. In Kamen Rider 555, Humans who had surpassed death became Orphnochs. In Kamen Rider Hibiki, there were the Oni, Humans who have undergone physical training to boost their abilities. In Kamen Rider Wizard, there are humans with magical potential known as Gates, housing creatures called Phantoms.
