The Alpha Centaurians were aliens from a planet where life had evolved on land before it migrated seawards. When their planet began losing its water due to vapor dissipating into space, they built a fleet of ships to steal water from other planets. They came to Earth to find water as well, but when they saw the amphibian Sub-Mariner, they made a deal with treacherous high priest Kormok, hoping to evolve themselves into amphibious creatures as well. They were defeated by Namor and Triton.
Their planet, Arima, was completely submersed in water. When Galactus came to feed upon it, the Keeper (the Silver Surfer) transported them to Centauri IV, home of a blue skinned, primitive culture.
After the Guardians of the Galaxy travelled back in time to the late 20th century of Earth-616, their actions on the planet Moord somehow changed the timeline of Earth-691 so that the Badoon attacked much earlier than they originally had and made the Alphans extinct. After discovering what had happened, the joined Starhawks travelled back in time and negated what the Guardians had done, restoring the timeline to how it had been.
