Orphnoch are fictional creatures from the Kamen Rider series, specifically introduced in Kamen Rider 555. They are a race of humanoid beings that possess both human and monster traits, created from the DNA of humans and the Orphnoch species. Their primary goal is to coexist with humans, but they often find themselves in conflict due to their inherent powers and abilities. In the series, Orphnoch can transform into powerful forms, gaining enhanced strength and agility. They are often depicted as antagonists, but some characters struggle with their identity and the desire for acceptance among humans. This duality adds depth to their portrayal in the storyline.
