Greg Osborne was a corrupt CIA agent who came into conflict with Green Arrow several times. His crimes included drug trafficking to fund missions not sanctioned by the United States government. The last of these was when he blackmailed Green Arrow into tracking down the assassin Shado and used connections in the Yakuza to make sure the job got done. He is arrested by the FBI and sent to prison, where it is implied he will be murdered by Yakuza. After this, he is not heard of again for years, but he eventually resurfaces, brainwashing Arsenal into assassinating Green Arrow, and using his daughter, Lian as leverage. However, Arsenal eventually breaks free of his indoctrination, and confronts Osborne along with Arrow and Shado. After a tense armed standoff, the three archers kill Osborne and rescue Lian.
