Third races

The term third race refers to species neither Shi'ar nor Humans. When humans were being absorbed into the Shi'ar Empire thanks to the conquest of Kree Empire territory, they eventually became the second most influential race in the Empire only behind the Shi'ar themselves.

Of course, a number of third race members of various species served in the Imperial Navy, especially as Imperial Navy troopers, and some appointed senators in the Imperial Senate were members of the third races.

On the other hand, very few Imperial Stormtroopers were of the third races, and almost no Supreme Chancellor was of the third races.

The use of this term continued after the Shi'ar Empire absorbed the Galactic Republic (itself a government largely dominated by humans) and became the Intergalactic Empire.

Under the present-day Empire, a number of third race members, particularly Kree and Skrulls, have joined the Rebel Alliance in order to overthrow the present Imperial regime.
