Myg was the second hero to take up the title of Karate Kid. After Karate Kid death, his will was read with a request to Timber Wolf and Sensei Toshiaki to travel to the planet Lythyl. The planet was ruled by the council of three judges, who include a teenager named Myg. After engaging the pair in a test of hand-to-hand combat skills, Myg was knocked unconscious by Timber Wolf and Sensei.
They smuggled him off the planet so that it would not corrupt him as it corrupted Val Armorr's father, the Black Dragon. Myg was brought to Shanghalla, the memorial planetoid for fallen heroes. Humbled by the level of respect given to the fallen hero, Karate Kid I, Myg vowed to follow his teaching. He became the new Karate Kid and enrolled in Legion Academy. He later had a short tour as a member of the Legion of Substitute Heroes and, eventually, as a full member of the Legion of Super-Heroes.
