Legion of Super-Heroes (1980) # 310 - Omen

The Legion of Super-Heroes face the threat of Omen on the planet of Khundia. Unfortunately for the Legion, the Khunds do not want the Legion's presence on their planet and would consider it an act of war if they fail to vacate their planet. When Phantom Girl is stuck behind an energy sphere that Omen has created, the Legion have no choice but to stay and fight both Omen and the Khunds. The Legion soon learns that Omen is on Khundia because he was attracted by a negaton bomb that is housed there. Dream Girl is able to detonate the bomb to destroy Omen. After the dust settles, the Legion are shocked to find Lyle Norg, the original Invisible Kid, laying down in front of them where the bomb was.
