Superman: World of New Krypton #3

Zod allows Kal-El thirty minutes to negotiate with the labor guild hostage-takers. When Alura finds their leader Tam-Or's demands reasonable and acceptable, the hostages are released. Commander Gor, not satisfied with the outcome, tries to assassinate Tam-Or, but Supergirl saves his life. Humiliated by Kal-El's actions, Gor challenges Superman to a physical duel. But Kal-El teaches Gor that though he now has the same super-powers as Superman, he doesn't have Superman's experience with them. Just as Superman puts down Gor, New Krypton receives a visit from the Green Lantern Corps.
