Zeta Metroid

The Zeta Metroid is the third stage of a typical Metroid's life cycle. The Zeta Metroid has a very different structure from the previous three forms; it gains a bipedal structure with a tail, and its limbs become clawed. The head is separated from the rest of the body by a short neck. In the place of a Gamma Metroid's beak, the Zeta Metroid grows a leech-like mouth.

Samus Aran encountered Zeta Metroids during her mission to [[SR388].
