Chomin was an inhabitant of the Anti-Matter Universe and came from the planet Qward. After encountering the Green Lantern Corps protector of Earth, the Weaponers of Qward decided to hatch a complicated scheme in order to depower him and destroy him. This led to them dispatching two Qwardians to the positive matter world of Earth where they disguised themselves as salesman with one of their number being Chomin. At some point, this operative began to make a connection between the mysterious Green Lantern of Earth and Hal Jordan; an employee at Ferris Aircraft.
