Ogrons are a form of higher anthropoid - tall, stout, ape-like aliens which used to live in scattered communities on one of the outer planets. Their planet is located in an otherwise completely uninhabited sector of Draconian space, and it is a stark, rocky place. The main lifeform on the planet is some kind of large, savage reptile. But to the Ogrons, the main lifeform is a billowy orange monster with tentacles. They fear it, and worship it as some kind of god.
As sentient aliens go, the Ogrons are rather simple-minded and stupid. They are highly subservient and seem to be very happy blindly obeying the orders of their masters. Because they are so loyal, and honest to boot, they are often employed as policemen - or mercenaries, used to do others' dirty work. When the Master employs them to attack and board ships and steal their cargo, to make the Earth and Draconian empires suspect one another, he equips them with a neuronic stun gun which can also kill people, burn through metal doors, and blow the locks off doors. They are very burly and strong. While Ogrons do speak, their speech is slow, reflecting their ponderous thought processes. They usually lumber around, but can be quick when the need arises.
