Rigellians

The Rigellians were a race of space colonizers. Threatened by the expansion of the Black Galaxy and Ego's attacks, they sought new worlds to colonize for when they would have to leave their home planet. A Rigellian colonizer, Tana Nile, tried to take control over Earth, but was not taken seriously by the authorities.[1]

Later, when the Black Stars set out for their home planet, Rigel-3, all Rigellians fled it in a desperate attempt to survive. Thor arrived and rescued the Rigellian mutants that had been left to die by the normal Rigellians. Not long after Rigel-3 had been fully evacuated, the Black Stars destroyed it.[2]
