The Mighty Morphin Power Rangers, also known as the Power Rangers are "teenagers with attitude" that Zordon recruited to battle Rita Repulsa using the power that they wield with their Power Morphers and Power Coins. They developed a strong sense of unity, but whenever one had to move on with his or her life, Zordon appointed new ones to take over.
When Rita Repulsa and her minions were freed from their imprisonment on the moon, Zordon took action to prevent her from taking over the Earth unchallenged. Instructing his childlike robotic assistant, Alpha 5, to recruit "five teenagers with attitude," he chose Jason, Billy, Trini, Kimberly, and Zack to receive the five Power Coins in his possession and become Power Rangers. These five rangers thwarted many of Rita's plots, but nearly met defeat when Rita used a sixth Power Coin to transform Tommy into her own evil Green Ranger. Tommy succeeded in cutting off communications with Zordon and trapping the Rangers' Zords before unleashing his own Dragonzord. However, Alpha was able to restore the Command Center's link with Zordon, who helped bring the Zords back, allowing the Rangers to defeat Dragonzord. Once Jason destroyed Tommy's Sword of Darkness, Tommy was freed from Rita's control, and immediately became a new member of the team.
