Rigellians
An advanced race that likes to colonize other planets.
Origin
The most famous colonizer is Tana Nile. Their people are also called the 'Colonizers' for their far-flung colonization of planets. The Grand Commissioner explained the driving force behind their colonizing zeal as, "We hate the stink of bodies around us."
They were driven from their home planet of Rigel when the Black Stars invaded their part of the galaxy and consumed the matter of their planet.
The Rigellians also created Recorders to help them in their efforts of planet colonization.
Creation
The Rigellians were created by Stan Lee and Jack Kirby in 1966 and first appeared in Thor # 131.
Alternate Realities
Earth-829
In this reality, the Rigellians combined themselves with the Recorders, becoming mostly cybernetic. They also increased their height greatly.
