Superboy #147 May-June 1968 Replica Edition #[nn]

In a bold new chapter of the Superboy mythos, three young heroes—Lightning Lad, Cosmic Boy, and Saturn Girl—rise to fame after rescuing billionaire R.J. Brande, who funds their mission to form a team echoing Superboy and Supergirl’s legacy. With sleek new costumes, a chosen leader, and a constitution in hand, they lay the foundation for something greater. As the ranks grow, Triplicate Girl and Phantom Girl soon join the ranks, marking the true beginning of the Legion of Super-Heroes.

Ultra Boy faces a daunting challenge: uncovering Superboy’s secret identity as part of his initiation into the Legion, all while a mysterious invitation from Marla sends Pete Ross on a surprising journey to Legion Headquarters.

When Superboy is betrayed by his Legion teammates under the mind control of the Brain-Globes of Rambat, he must confront his closest allies turned enemies. Once freed from the alien influence, the Legionnaires unite with four extraordinary super-pets to form a new, heroic team—officially christened the Legion of Super-Pets.

Superboy faces a double threat when a new Legion recruit, Sun Boy, arrives with mysterious motives—while a look-alike named Tom Tanner escapes reform school and sets his sights on replacing Clark Kent in Smallville.

In a bold twist of time and tide, Lex Luthor unites with a notorious band of 30th-century villains, forming the Legion of Super-Villains to challenge the heroes of the present. When an adult Legion of Super-Heroes arrives from the future to aid Superman, the clash of eras and ideologies sets the stage for a high-stakes battle across time.
