Green Lantern #6 (2005)

Doiby's assigned to find the lost South American nation of Exilia, as it's supposedly rich in resources that would be a boon to the war effort. Wickwar, the only explorer who knows how to find Exilia, has recently given up his hermit's ways and wants to reveal what he knows. However Wickwar's already been visited (and abducted) by Pelk, a synthetics manufacturer afraid of losing his market share if the wealth of Exilia's brought to America. Helping him are some Nazi spies planning to capture Exilia's resources to fuel the German war machine. Green Lantern and Doiby visit Wickwar's house, inadvertently obliterate Wickwar's treacherous butler by rebounding his grenade back at him, and follow the trail to the Nazis' hideout. They subdue the spies and find Wickwar, who's fading fast after the Nazis' rough persuasion tactics but reveals how to find Exilia to Green Lantern. However the Nazis set off charges in the house with Green Lantern and Doiby still inside.

The heroic duo survive and hop a military plane to Exilia, where they're shot down by the locals using giant ballistas. Doiby bails out and lands not far away from a beautiful woman who finds herself charmed by the portly stranger, especially when he knocks out her indignant fiance with one punch. As its name suggests Exilia is home to exiles from many different nations, all going about in their respective national garb, and all respecting mighty warriors. Doiby's new rival challenges him to a formal duel that soon turns into a melee with all of his followers jumping in to teach Doiby a lesson (and Doiby not realizing he's not quite the whirlwind he thinks he is as Green Lantern's helping out by melting the attackers' weapons and knocking them out when he isn't looking). A policeman brings Doiby before the king of Exilia, who declares Doiby an enemy of the people for being an ally of Green Lantern and throws him into an arena with an assortment of vicious animals.

Green Lantern gets into a fight with an opportunist German expat which ends with Green Lantern easily defeating him and taking his uniform to look less conspicuous. Soon he runs into Nordo, the Nazi who oversaw Wickwar's abduction and already head of the German expats in Exilia. Nordo lets slip he plans to depose Hitler eventually, and also that Doiby's been thrown into the arena. Green Lantern knocks him out then throws off his disguise and flies to help his friend. They escape into the king's palace where he takes them captive and demands they reveal what they know of the American war effort, as he plans to conquer the United States. A fight breaks out with the king's guards and in the course of the fight the king's revealed to be nothing but a dummy, operated by a lady named Shiloh. She admits her grandfather fought for the Confederacy in the American Civil War, and after it was beaten he came to Exilia, and she's nurtured that desire to finish what the Confederacy started that drove her grandfather. Green Lantern tells her he had a grandfather on each side of that war, but they've united since then. Shiloh, convinced by Green Lantern's story that peace is better than war, agrees to turn her influence to having Exilia help the Allied war effort. However Nordo's already taken advantage of the power vacuum and whipped the Exilians into a blood frenzy for Green Lantern and Doiby.
