@Gentle Sharptooth In "The Hermit of Black Rock," Swooper was the titular character, the old flyer Guido and Petrie met when they crash-landed in Black Rock. He had been able to survive in Black Rock for a long time by learning his way around the caves, but his blindness prevented him from leaving on his own, so until Guido and Petrie showed up, he was leading a hermit's life, making friends with rocks and stuff.

Eventually, he, Guido, and Petrie had to team up to fly back to the Great Valley. Looks like his friendly/quirky character and contribution to the episode's plot make him the TV show fan-favorite, because he's outpacing everyone else in this poll by quite a bit! I suspected that he'd be one of the more popular choices, but I didn't know it'd be by that much.
