Turbotron versus Exacto?
No, it's Michael versus obnoxious Todd Newman.

Jeremy, Lee, and Michael Jenkins are psyched. Their mother's going to present Turbotron, the superstar superhero she created, at a comic book convention. And she's taking her three sons along. Michael will even get to play Turbotron in costume at the show. But jealous Todd Newman has other ideas. His father owns a rival comic book company, and Todd's planning a mean trick to make Turbotron look stupid -- unless the Jenkins brothers can stop him.
