Five teenagers battle against the witch Rita Repulsa and the wizard Lord Zedd to defend the earth. They have large robots called Zords and battle suits for their fights. They are armed with special weapons like swords, axes, bows, daggers and lances to help them fight monsters. Rita and Lord Zedd have an army of fighters known as Putties, which get destroyed and broken into many pieces when they are hit by their weak spot - a Z plate on their chest.
