Synopsis:
Mxyzptlk returns to Earth to plague Superboy. Lex Luthor seizes the opportunity and builds a machine to siphon off Mxyzptlk's powers and give them to himself. Angry that he was upstaged, Mxyzptlk starts a battle with Luthor with Superboy caught in the middle.

Superboy tricks Mxyzptlk into saying his name backwards, sending the imp home to Zrfff. Luthor retains his powers though. Superboy tries the same trick on Lex, but even when he says his name backwards, Lex's powers don't disappear. Superboy then examines the machine that gave Lex his power. After completing his analysis, Superboy finds a way to remove Lex's powers using a coded set of numbers which represent Lex's name.
