Synopsis:
Superboy uses his mind-prober ray to retrieve forgotten memories from his own mind. Using the machine, he learns that he was kidnapped from Krypton as a small child by Brainiac. Brainiac takes him to the planet Bryak which has a yellow sun, resulting in young Kal-El acquiring super-powers. The mischievous child creates so much trouble for the outlaw, that Brainiac returns him to Krypton vowing to return later to avenge his humiliation.
