Johnny Test: The Once and Future Johnny

In this standalone 2011 one-shot from Viper, Johnny Test races through time to fix a future gone haywire—a fast-paced, all-ages adventure tied to the animated series. The issue captures the show’s signature slapstick energy and sibling rivalry, with Johnny and his genius sisters Dukey, Susan, and Mary at the center of the chaos. While brief, it’s a fun, self-contained snapshot of the franchise’s comic-book era.
