When the evil witch Rita Repulsa and her minions Goldar, Squatt, Baboo, and Finster, are freed from their imprisonment on the Moon, the wizard Zordon, with the help of his assistant Alpha 5, enlists five teenagers—Jason Lee Scott, Trini Kwan, Billy Cranston, Kimberly Hart, and Zack Taylor—to become the Mighty Morphin Power Rangers to battle Rita's invasion of the Earth, using their Power Coins and Dinozords to combat her monsters. Rita soon creates her own evil Power Ranger by brainwashing a recent transfer student Tommy Oliver, but the Power Rangers are able to free him from her control and he joins their side.
