Tales of the Legion of Super-Heroes in "The Legion's Space Odyssey!"
Dream Girl reveals a dream to Superboy only. Soon, several Legionnaires are teleported to a remote planet where Superboy is killed by a monster with kryptonite teeth.
The remaining Legion members make their way back to Earth to find Superboy alive; it was all planned to keep the Legion safe and to prevent Dream Girl's prophecy from coming true.
(This is the last Legion of Super-Heroes story in Adventure Comics; after this issue they move to Action Comics with issue #377.)
