The alien creatures known as the Brain-Globes of Rambat decided that, in order to succeed in their plan to move Earth to their own solar system, they would have to defeat Superboy. When they are unable to gain control of Superboy, they summon Cosmic Boy, Lightning Lad, and Saturn Girl of the Legion of Super-Heroes from the future and mentally command the trio to capture him.
After Superboy is defeated, the Brain-Globes of Rambat release their hold on the Legionnaires. When they notice that the Brain-Globes cannot control animals, the Legionnaires gather Krypto (from Superboy's present), Streaky and Beppo (from Superman's present), and Comet the Super-Horse (from a few weeks in Superman's future) to battle the aliens. The pets defeat the aliens and are named the Legion of Super-Pets, the animal branch of the super club. They are then returned to their proper time periods.

- This version of Legion of Super-Pets, including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. Even though versions of the character may have since appeared, this information does not apply to those versions.
- The team first appeared in Adventure Comics #293 (February 1962), though most of the members had appeared in earlier issues.
- The full squad appears during a segment for Robot Chicken, where the team, which also includes "Hissy, the Super Snake", are left at the Fortress of Solitude while Superman is fighting at space. Upon his return, he finds that all the Super Pets are dead and have been frozen by the frigid temperatures. It is later revealed that the one who was supposed to take care of them thought the job was supposed to be on the next month.
