The Dominators storyline comes to a surprising conclusion that will change the lives of the Legionnaires irrevocably!
The votes are in! The newest leader of the Legion of Super-Heroes is Supergirl. She meets up with Tenzil Kem, a prosecutor from the United Planets hired to find if Cosmic Boy is responsible for the death of the entire race of Dominators. Brainiac 5 informs Supergirl that he knows the three most likely areas where Cosmic Boy would be found and Supergirl sends three teams to scout each area. Ultra Boy, Shadow Lass and Atom Girl visit the planet of Lallor. Supergirl, Saturn Girl and Lightning Lad go to the Gobi Rainforest on Earth. Sun Boy, Star Boy and Mekt Ranzz go to Ranzz's homeworld of Winath, where they are met with Tenzil Kem.
