Rubelans

Not much is known about the Rubelans. They are an extremely powerful cybernetic race who consist of a humanoid brain inside a suit of armor which was built by the immortal telepath Madam Eterna. They have a tendency to travel through space and land on planets to cause random destruction. They either go in small numbers or one at a time. The only known events in which Rubelans swarm planets in mass numbers is when they are called on to attack by their master. Their emotions are either neutral or angry and they're incapable of independent thought as their once human brains have been warped by dark energy.
