Antaran

The Antarans are one of the elder race sin the Master of Orion Universe.

Culture
A race of paranoiacs who have an instinctual talent of analyzing an opponent and finding their weaknesses, known throughout galactic history as the Destroyers. The Antarans are what you'd call 'control freaks'. They can't accept anything being outside their domination. That means races weaker than them are conquered or destroyed so they can never become a threat, and races powerful enough to threaten them are just outright destroyed.
