Green Lantern / Green Arrow #1 (2004)

Green Arrow shows Green Lantern the plight of the people living in the tenements of slumlord Jubal Slade. But when the Guardians of the Universe observe GL roughing up Slade, they bring him to Oa and reprimand him. Against their orders GL returns to Earth and collects evidence to put Slade away. In response, the Guardians contact Green Lantern, but Green Arrow argues that there are serious problems across America that have escaped the attention of Green Lantern. The Guardians confer, and decide to send a representative to accompany the two heroes as they go on a journey of discovery.

Green Lantern, Green Arrow, and the Old-Timer come across the company town of Desolation, where the boss Slapper Soames plans to execute Johnny Walden to silence the songs he sings which have inspired the people of Desolation to think about a better way of life. As Green Lantern joins the townspeople in attacking Soames' stronghold, the Guardians inform him that since he is on a leave of absence they have reduced the power of his ring. But even weakened, Green Lantern and Green Arrow are able to free Johnny and turn Soames and his men over to the authorities.

Green Lantern and Green Arrow get involved in a dispute over logging rights on Native American land. While GL searches for documentation for the Indians' claim, GA tries to inspire them with the ghost of their ancestor.

For putting the welfare of Green Lantern ahead of the ecological welfare of the planet Earth, the Guardians of the Universe send Old-Timer, accompanied by Green Lantern and Green Arrow as witnesses, to the planet Gallo to be judged by the Tribune.

Green Lantern and Green Arrow, now joined by Black Canary, travel to Oa and find that Old-Timer has been found guilty by the Tribune. The Guardians strip him of his immortality and sentence him to live out his days on the planet Maltus. The heroes go with him into his exile and discover a planet wildly over-populated due to the efforts of Mother Juna. After they put a stop to her work, the Old-Timer vows to restore balance to Maltus.

When Green Arrow and Black Canary are confronted by harpies, GA calls Green Lantern for help. GL follows the harpies into a trap laid by The Witch Queen on behalf of her brother Sinestro.

With this information, the duo follows the trail to The Witch Queen and rescue Green Lantern from banishment and the grasp of the legendary Medusa.
