Andromedon

Serving the Ethereals during their occupation of Earth, Andromedons are unable to survive in Earth's atmosphere, and so are confined to a heavily armoured environment suit. The gasses required by the Andromedon to survive are proven to be toxic to Humans, which they take advantage of in their use of acid bombs, likely containing and releasing the gas in their suits. In the event that an Andromedon is killed, their suits will reactivate and behave autonomously. Without the operator, the robotic suit loses functionality to many systems, primarily the Andromedon's weaponry, but will continue to engage the enemy in close-quarters combat.
