Shoofly Pie, Igneous Rock Pie's brother, is the head of the gang. He's big, loud, and, above all, fun. If you're sad, Shoofly will scoop you up in his troika and drive you around town, jumping over fences like hurtles, singing loud enough to scare off pedestrians, and just being an absolute madman. He has no qualms about stealing from the rich, confusing the heck out of LEOs by playing pranks on them, or practicing a little civil disobedience.
Wanderlust was a geologist and teacher back in Hallow Shades. He was revered and respected by his students and fellow professors, and he had a good life— until he saw something he shouldn't have while on a spelunking trip in the caves beneath Canterlot. Ever since, he's been on the run from the royal guard. He knows a lot about the geography and culture of most cities in Equestria, so he acts as the team's encyclopedia, tour guide, and negotiator.
Bardolino, AKA Bard, is the mysterious one. He's a sharp-shooting, gun-slinging, smoke-spitting old cowboy with a story behind every one of his scars. He can't fly, but he can use his wing to give himself an extra boost when he's running or jumping, and he's probably the fastest of the three. Shoofly and Wander don't really know where he came from or what he's after, but they love him anyway. He's usually the group's voice of reason— though, if you get him really excited, he'll go absolutely buck wild.
