Comments:
When this story was reprinted in Adventure Comics #371, two new panels were added and some dialogue was altered to include the Legion of Super-Heroes, who were not present in the original story.

This story was originally entitled:"The Valhalla of Super-Companions".

Ultra Boy, Triplicate Girl, Sun Boy, and Lightning Lass appear in two new panels on page 4, but were not in the original story.

Lightning Lass is depicted, but she was not a member of the Legion at the time this story takes place.

Synopsis:
An alien ship arrives on Earth and puts the residents of Smallville to sleep. Othar, the alien leader, wants Superboy to return to his homeworld of Thrann to live. The Boy of Steel is forced to comply in order to wake the sleeping people. Othar stops at several other worlds and blackmails their heroes into coming to Thrann as well.

On Thrann, the heroes compete to determine leadership. Superboy wins by performing the greatest feat, but everyone misses their homeworlds. The heroes begin to fight among themselves, forcing Othar to realize his mistake in bringing the heroes to Thrann. He allows them to return home where they belong.
