Still drawing his own layouts, finished by Curt Swan and George Klein this time, Jim Shooter created an enduring Legion villain, Universo, and an important supporting character, Rond Vidar. (Although, surprisingly, Rond is not named in this story. He’s just, “The kid who invented the time cube.”)
Like the Dr. Regulus story last issue, this story opens more traditionally than Shooter’s “One of Us Is a Traitor,” with the Legionnaires visiting a science fair. It then uses the same device used last issue to pull the team away from a public appearance—an emergency at the clubhouse. Brainiac 5 informs them that someone is desperately trying to break in, though he never explains how he knows.
