Human

Humans (Homo sapiens) are primates of the family Hominidae, and the only known existing species left of the genus Homo.

In the Kamen Rider continuity, 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 have made their own civilization, but were divided by their beliefs. One tribe were known at that time as the Gurongi, who have 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 have lived peacefully, were known as the Linto. Being a peaceful tribe, they never have 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 desire.

About 800 years ago, a group of alchemist 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 onto himself, the process backfired and the OOO driver sealed the medals with the Greeed and the king inside a sealed sarcophagus.

During the Showa era, Shocker and other organizations have experimented on humans and made their own artificial humans which were Cyborgs and Mutants.

During the Heisei period, other races that were similar to Humans emerged. In Kamen Rider 555, Humans who have surpassed death became Orphnochs. In Kamen Rider Hibiki, there were the Oni (Humans who have undergone physical training to boost their abilities). And in Kamen Rider Kiva, there were the 13 Demon Races in which the Human Race was a part of.

In Kamen Rider Den-O, there were humanoid-like beings that were known as Imagins that are from the future. The Neo-Fangires, a new breed descended from Fangires, were also from the future.
