Pseudoroids are physically similar to the Mutos Reploids of the Mega Man Zero series. Instead of a human appearance, Pseudoroids resemble mechanical animals (or plants) with humanoid traits. Despite this, Pseudoroids are unique for the fact that Biometals (or fragments thereof) are used in their construction. Certain lines from a few Pseudoroids suggest that at least some of them were not actually born as Pseudoroids, although their actual origins were never revealed.
