On Rimbor, word of the asteroid's collision has caused mass hysteria. As the Legion heads for Rimbor, they are contacted by Lyle Norg (Invisible Kid) and Querl Dox (Brainiac 5), informing the Legion that Superboy's plan to smash the asteroid will fail because the asteroid is too large. The Legion calls in Thom Kallor (Star Boy), the last survivor of the planet Xanthu, who uses his gravity powers to increase Superboy's mass to stop the asteroid. Superboy shatters the asteroid, and the Legion collects the fragments.
