Masquerading as Superboy, Dev-Em blackens his rival's reputation with his parents and the people of Smallville. Then he releases Superboy from the Phantom Zone and takes himself and the space capsule bearing his parents into the future. Superboy finds that only the Kents believe his story of Dev-Em's impersonation, and he is ordered by the mayor of Smallville to leave Earth.

The townspeople change their minds, and Superboy is allowed to stay.

Bizarro Mxyzptlk gives Bizarro Lois No. 1 super-powers, and she assumes the secret identity of Stupor-Woman to help female Bizarros.

Perry White exposes Bizarro-Clark as both Bizarro No. 1 and Stupor-Man because he wears his "Bizarro No. 1" medallion in plain sight.
