He-Man and the Masters of the Universe

An evil king from the Dimension of Evil has kidnapped a good wizard. In order to get his freedom back, his daughter makes a bargain that she will kidnap the Star Child so that the evil king can look upon her. However, she soon finds out that she's bee duped when the evil king breaks his bargain and transports her, the Star Child and the heroes (along with the Star Child's body guard) to his dimension, hoping to force the Star Child to use her powers to open a gate to Eternia for himself and his forces to come through and take over.
