As a Green Lantern, Barin Char was responsible for the protection of the myriad worlds of Space Sector 1522. During his time in the Green Lantern Corps, Barin Char had the opportunity to serve with other Green Lanterns, including Kilowog of Bolovax Vik. It was on a border world in his sector that Barin Char met his gruesome fate.

In an isolated area of the planet, a previously unknown alien species had set up a hive within a rock formation. The Green Lantern was investigating the aliens which would, if left unchecked, pose a threat to the population of the planet.

Somehow Barin Char was separated from his power ring and at some point either before or after, was attacked by a "face hugger," a creature which hatched out of the aliens' egg and would forcibly plant an alien within a victim. Barin Char was then partially cocooned in the hive while a new alien gestated inside him. When it was ready, the alien violently burst free from Barin Char's body, killing the Green Lantern.

The Guardians of the Universe dispatched six veteran Green Lanterns to discover what had happened to their fellow ring wielder. Kilowog, Katma Tui of Korugar, Salakk of Slyggia, Green Man, Tomar-Re of Xudar, and Hal Jordan of Earth would learn why Barin Char had not reported to the Guardians. It was Hal Jordan that found Barin Char's ring and lifeless body. After a brief struggle with the acid-blooded aliens, the Corps removed the aliens and their eggs from the planet to be transplanted to a planet on which they would not prove a threat.

It was decided that the planet Green Lantern known as Mogo would be the safest place in the universe for the aliens to reside.
