Dragonzord lay dormant in the sea off the coast of Angel Grove for an indeterminate number of years. After creating her evil Green Ranger, Rita Repulsa gave him the Dragon Dagger, granting him the power to summon and control the Dragonzord. When her spell was broken and Tommy joined the Power Rangers on the side of good, he retained the dagger and control of Dragonzord. Later, when Rita’s green candle sapped the Green Ranger powers, Tommy bestowed what remained of them on Red Ranger Jason. He was then able to summon the Dragonzord via the Dragon Dagger even while Tommy was out of action. During a crisis, Zordon infused Tommy’s power coin with some of his own great power, allowing him to return to the fold as the Green Ranger and reunited with Dragonzord. Later, when Lord Zedd took over from Rita and sent his Pirantishead monster to Earth, Dragonzord was corrupted a second time by the creature, who froze four of the Dinozords and turned Dragonzord and the Tyrannosaurus Dinozord against the Power Rangers. The Rangers were able to regain control of Dragonzord, however Tommy was forced to return it to the sea to protect it. As a result of this incident Dragonzord was severely weakened and, like Tommy, would have its powers occasionally fail. Tommy didn’t use Dragonzord much from this point on; in addition to its power growing weaker and weaker alongside Tommy’s own (with one attempt to summon it failing completely), the Dragonzord was incapable of combining with the newer Thunderzords, further limiting its usefulness. Unlike the other Dinozords, Dragonzord was not able to transform into a Thunderzord since Tommy’s power were too weak to allow this. Its final battle for the Rangers occurred when it fought Turbanshell and was easily defeated by the powerful monster.
