SHI'AR

The Shi'ar are oviparous humanoids of avian descent; resembling humans with feathered crests atop their heads in lieu of hair.They have light hollow bones, and some vestigial feathers on their forearms, left of wings that were lost over evolution. Through freak genetic throwbacks, some individuals still possess wings which allow them to fly. The average Shi'ar can lift 1 ton in earth-like gravity and has far greater stamina.

With a monarchic society, they are expansionnist and aggressively absorb new cultures.While the empire has grown to include hundreds of thousands of different sentient species and worlds, the Shi'ar race controls and governs the empire. Its central base of power is located on the "throneworld" Chandilar, while the Shi’ar homeworld is called Aerie. Leadership of the empire is am hereditary position, occupied by members of the royal family.The Shi'ar Empire is one of the most advanced and expansive civilizations in the universe, spanning an entire galaxy and spawning into others. It is mainly an economic co-operative, where trade is the driving force. Though having warlike and militaristic ancestry, the Shi'ar Empire has largely occupied the role of peacekeepers in many interstellar affairs.
In 1992, the Shi'ar annexed the Kree Empire at the end of the Kree-Shi'ar but internal affairs made the Shi’ar abandon their dominion soon after. Most recently, The Shi'ar have had contact with the Spartoi, described as an equally advanced distant race.
The Shi'ar possess faster than light starships, force fields, faster than light communication, teleportation technology, advanced holographic technology and Cloaking technology, Stargates network system used for travel to faraway distances, both planet-based used for personal travel and space-based versions used for starships to travel through, Starcracker technology that can cause stars to go supernova. Most of their technology is sentient.Source: X-Men vol. 1 #97 (February 1976) by Chris Claremont & Dave Cockrum. Marvel Universe
