Bizarro is content "protecting" his own "town" on a deserted planet - until Mr. Mxyzptlk turns up. The imp claims that Superman sent him there out of jealousy and really despises him. Then he sends the enraged clone back to Earth and follows him to watch the fun. However, the Tribunal of the fifth dimension have observed Mxy's antics, and they are not pleased. Stripping him of his powers, they send him to Earth until he can do three months of good deeds for the people he's been tormenting. Meanwhile, Superman has to convince the enraged Bizarro that he's been lied to.
