Gleen is the Sinestro Corps member of Sector 312.


Gleen was a native of Krolotea, and was feared throughout his sector for his tampering with evolutionary patterns. He was part of a group of Krolotean gremlins that was responsible for Hector Hammond's telepathy, the Shark's rage, and initiated the experimentation on Black Hand. He was most feared among the Kroloteans, and was recruited to be the representative of the Sinestro Corps in Sector 312.
