Billy

Bursting onto the comics page in 2006's Cartoon Network Block Party #21, Billy is a Modern Age creation from Scott Roberts and Cindy Morrow that brought the anarchic spirit of animated mayhem straight into DC's all-ages lineup. His handful of catalog appearances place him alongside some seriously colorful company — Grim, Mandy, Johnny Bravo, Buttercup, and Blossom all share his pages — making even his small comics footprint feel like a genuine Cartoon Network crossover event. Collectors with a soft spot for early 2000s animated nostalgia will want to track down his key appearance in Super Secret Crisis War! The Grim Adventures of Billy and Mandy One-Shot, a title that practically announces its own must-read status.
