Autocron

The Autocrons are a humanoid race with blue-black skin that inhabits the planet Cron.

Biology
They are not a carbon-based lifeform and are instead iron-based, which likely is the direct reasoning behind their superhuman strength and durability.

Culture and society
They have a technocratic government, and a technological level superior to that of modern-day Earth. They are ruled by a super world-computer, which has set their culture to be an imperialistic, militaristic, and orderly one.
