Android

Androids are purely mechanical humanoids. Some appear to be simple robots, while others are designed to blend into the societies of other life-forms such as those of the Human and Beastman.

Description
'Metal men created before the fall of civilization. They were originally used to excavate resources deep underneath the crust of the Earth. Thus, when the Fall came, many of them were largely unaffected by it. Contrary to what the past might suggest however, they have been almost universally hostile to organic lifeforms since reappearing on the surface of the Earth.' -- In-game Description

Androids are in truth a species that are extremely powerful due to them lacking the frailties that plague organic lifeforms such as weak hearts, needing to build up stamina, and other, similar attributes. They have the highest energy mod in the game, most being capable of developing energies greater than 10`000x that of base by year 50.
