Metroid/Enemies

There are 25 distinct species of basic creatures that Samus will encounter throughout her mission to defeat Mother Brain. Zebes has a very harsh ecosystem, one that only the fittest can survive in, and these evolution of these creatures reflect that. In a world where resources are limited, only the most aggressive species have manage to survive such an unrelenting environment. Many of the creatures follow similar behaviors to one another, having evolved from a common ancestor at some point, and then branching out to different regions of Zebes and adapting to the local environs. Creatures with common traits are grouped together.
