Synopsis:
After attending the dedication of a Sun Boy statue, Sun Boy finds that his powers of heat and light have stopped working. With the help of the Legionnaires, he tries to recharge himself by duplicating the accident that gave him those powers, but to no avail. After his powers briefly return in an entomologist’s office, he invites Ultra Boy and Superboy to concentrate their heat vision powers on him, still with no effect. Heartbroken, he resigns from the Legion, just as Kranyak, his old foe, breaks prison and comes after him.

More worried than before, Sun Boy realizes what it will take to recharge his powers, and deliberately walks into the blast of a Kryptonian flame-beast. With his abilities restored, he defeats Kranyak, and rejoins the Legion. He then explains that he needed the heat-energy of a living being to restore his power, and the Ultra Boy and Superboy present are robots, sent to take those heroes’ places while they celebrate Pete Ross’s birthday in the 20th century.
