Invisibility is a common plot used in many Hanna-Barbera cartoon series. Such ability was commonly used for the purpose of thwarting a villain's schemes, secretly foiling criminal activity, and at times, mischief. When a character becomes invisible, his or her clothing usually vanishes with him or her.

There is speculation that invisibility plots may have occurred because the artists who designed the characters may have needed a break from drawing, thus making an invisibility plot very useful to fill the episode order.

Examples of invisibility plots
