The Legionnaires fear acting directly against the Brain-Globes, who might subvert their will again. Noticing the Brain-Globes cannot control the minds of animals or Superboy's Kryptonian dog Krypto, they decide to recruit other super-powered animals from across time for help. Knowing Superman's future, they recruit Streaky the Supercat, Beppo the Super-Monkey, and Comet the Super-Horse (who they knew would be a companion to Supergirl after she arrived on Earth years later). The pets defeat the aliens and Saturn Girl declares the group of animals will now be honored as the Legion of Super-Pets, a special branch of the Legion of Super-Heroes. They then return the animals to their proper time periods, not telling Superboy how the Brain-Globes were defeated since he shouldn't know too much about his own future, including people and animals he has yet to meet.
