Mochtroid

The Mochtroid is a failed clone of the Metroid created by the Space Pirates. They are distinctly different from their progenerators in that they only possess a single neural brain node, instead of three that regular Metroids naturally possess. It also resembles a Metroid in that it floats, has a green membrane, but they are no larger then half the size of a regular Metroid, and most Mochtroids possess only 1/10 the strength of a natural larval Metroid. (Super Metroid, Metroid Prime: Hunters: First Hunt)

This species also appeared in the Maridia area of rebuilt Zebes. They were susceptible to any weapons, and did not have the ability to properly attach to its victim and, therefore, were obsolite.
