Reality with some similarities to Earth-691, in which the Guardians of the Galaxy exist very much like the Legion of Super-Heroes, including dozens of members like the Destroyer, Immortal One (apparently Wolverine) and Sun Girl the 52nd.
Unlike Earth-691, humanity does not seem to have been exterminated by the Badoon, and the Guardians are based out of the Guardian Dome, located on Earth. It has also on occasion faced attacks from a youthful version of Kang the Conqueror called "Kid Kang". The Sentry of Earth-1611 frequently travelled to this universe to share adventures with the Guardians.
