Streaky

An ordinary Earth tomcat belonging to Supergirl, Streaky accidentally gained temporary super-powers after exposure to X-Kryptonite — a variant of Kryptonite Supergirl had been experimenting on. His sporadic super-abilities eventually led him to join the Legion of Super-Pets.

Few comic book pets have earned a place in DC's constellation quite like Streaky, the super-cat who first bounded onto the Silver Age scene in Action Comics #261 in 1960, brought to life by the legendary Jerry Siegel and artist Jim Mooney. Sharing adventures alongside luminaries like Supergirl, Krypto, and Kara Zor-El across titles including Tiny Titans and Supergirl, Streaky occupies that wonderfully imaginative corner of DC where even a cat can be extraordinary. With a publishing presence stretching an remarkable 66 years from 1960 all the way to 2026, this feline has proven to have serious staying power — a beloved slice of Silver Age whimsy that collectors and fans keep returning to with genuine affection.
