Hal Jordan may be cocky, but theres only one Green Lantern whos the epitome of douchiness and deserves the #1 spot on this list: Guy Gardner. Although Hal received Abin Surs ring, Guy was designated as Hals replacement and handled the Lantern duties while Hal was out of commission. These days, with all the Lanterns the Earth has, Guy serves as a regular Green Lantern. While he has an abundance of willpower, Guy is one of the brashest and most arrogant punks the Corps has ever seen. Hell pick a fight with anybody, whether its an alien whos attacking innocents or someone who makes a snide comment about him at a bar. In his earlier appearances, Guy would also frequently advertise himself as Earths greatest Green Lantern, something which got him into arguments with Hal. Of course, the arguments werent solely with his fellow Corpsman. As a member of the Justice League International, Guy was at odds with several of his teammates, most notably Batman. This came to a head when Guy, sick of Batmans leadership, challenged the Caped Crusader to a fistfight, and it ended in seconds with Guy being quickly socked in the face. Batman was able to do what many DC fans had wanted to do for years, and weve been jealous ever since. Although hes been calmed down in recent years (although that Red Lantern ring hes wearing right now isnt helping), Guy will always be primarily recognized for his bravado and self-importance. He may be a great superhero, but that doesnt make his attitude any less annoying.
