The feline Antarians resemble bipedal felines. Individual Antarians may have patterns in their fur that resemble tigers, mountain lions, or any other feline. The males have large heads proportioned like a tiger or lion, while the female's heads resemble domestic cats.

Antarians are known as the merchants and financiers of space. Their entire culture is oriented toward commerce. They roam the galaxy in search of financial gain. They are experts in economic manipulation as well. Their trade ships range from merchant ships with multiple compartments for different trade goods to "Securities Ships" which are designed to infiltrate another planet's financial network.
