Stupidity: Zartan, as the president, asks the real president where Cobra Commander and Destro are being held. However, in the previous movie, he had already replaced the president when they were captured, which means they were transferred to the German prison while Zartan was posing as the president. If it was a preexisting facility known by the president, Zartan should have been told they were sent there. Thus, either Zartan has no reason to think the president knows where they are, or he has no need to ask.

Continuity mistake: When Duke and Roadblock are playing video games in Roadblock's house, Roadblock's kids come up and start messing with Duke. They knock Duke's headphones off and comment about his big ears. But then Duke stands up with them on his back and his headphones are on his head again. The next shot, they vanish. (00:05:20)
