Hal Jordan's enemies: Haasp

Brother of the Green Lantern Harvid, Haasp travels the cosmos, hunting the most rare and exotic breeds of sentient races and selling their skins on the black market. After an attempt to murder and skin one of the rarest species in the universe, his brother Harvid deemed him unstable and placed Haasp into a sciencell on Oa. Haasp eventually broke free from his sciencell and escaped, and he now harbors a deep hatred for his brother, whom he has designated to be his next big hunt. Haasp has yet to mention his other brother, Ghanrik, who was a criminal for a time, as well.
