Autocron

The Autocrons are a humanoid race with blue-black skin and two-toed feet. They are not a carbon-based lifeform and are instead iron-based, which likely is the direct reasoning behind their superhuman strength and durability. They are ruled by a technocratic government, and have a technological level superior to that of modern-day Earth. They are ruled by a world-computer, which has set their culture to be an imperialistic, militaristic, and orderly one.

Trivia

 * The Autocrons first appeared in Machine Man #3 (June 1978).
