The Dinozords were the first zords used by the Mighty Morphin' Power Rangers. They were called on whenever Rita Repulsa grew her monsters to giant size after the rangers beat them in their normal size. After Lord Zedd came to Earth, the Dinozords were greatly weakened and almost destroyed, but were then used as the foundation of the more powerful Thunderzords.
Tyrannosaurus DinozordThe Tyrannosaurus Dinozord was the zord of Jason Lee Scott, the Red Ranger, and was the strongest of all the Dinozords. It could fight on its own using its claws and tail in battle, even taking on the Dragonzord on its own. The Tyrannosaurus Dinozord could unleash powerful roars, that created seismic blasts. In the Megazord formation, it formed the head and torso and when not in use, it was hidden below the Earth. It was later used to create the Red Dragon Thunderzord.
Saber-Toothed Tiger DinozordThe Saber-Toothed Tiger Dinozord was the zord of Trini Kwan, the Yellow Ranger and was by far the fastest moving of the Dinozords. It had a laser cannon on its tail, but it could also attack with its fangs. In the Megazord formation, it formed the right leg and when not in use, it was hidden in a deep jungle. It was later used to create the Griffin Thunderzord.
Triceratops DinozordThe Triceratops Dinozord was the zord of Billy Cranston, the Blue Ranger. It was able to fire laser blasts from a twin cannon on its tail and send out chain-link power cables form its horns in order to subdue its opponents. In the Megazord formation, it formed the left leg and when not in use, it was hidden in a desert. It was later used to create the Unicorn Thunderzord.
Pterodactyl DinozordThe Pterodactyl Dinozord was the zord of Kimberly Ann Hart, the Pink Ranger, and the only Dinozord capable of flying. It could fire twin lasers which resembled lightning bolts when used on its own and in the Megazord formation, it formed the chest plate. When not in use, the Pterodactyl Dinozord was submerged in a volcano for hiding and was later used to create the Firebird Thunderzord.
Mammoth DinozordThe Mammoth Dinozord was the zord of Zack Taylor, the Black Ranger. It was able to unleash freezing blasts of cold air and mist at opponents. In the Megazord formation, it formed the arms and shield and when it was not in use, it was hidden in the Artic. The Mammoth Dinozord was later used to create the Lion Thunderzord.
DragonzordThe Dragonzord is the zord of Tommy Oliver, the Green Ranger, and later Jason temporarily after Tommy lost his powers for a time. This zord could be summoned from the ocean and controlled by the music played on the Dragon Dagger. Tommy first used the Dragonzord when he was being controlled by Rita Repulsa to attack Angel Grove, but after the spell on him was broken, Tommy and the Dragonzord began fighting alongside the rangers. After Tommy lost the powers of the Green Ranger again and became the White Ranger, the Dragonzord remained untouched at the bottom of Angel Grove Harbor. But it made its return after the Wizard of Deception created a clone of Tommy and granted him the Green Ranger powers, then had him steal the Dragon Dagger. The clone summoned the Dragonzord and had it attack Angel Grove, then battle the Tigerzord. But after the clone was freed from the Wizard's control, he returned the Dragonzord to the sea where it has presumably remained ever since. While formidable on its own and even capable of matching the Megazord, the Dragonzord could combine with the Mastodon, Triceratops, and Saber-Toothed Tiger Dinozords to form Dragonzord Battle Mode or the Megazord to form the Mega Dragonzord. The Dragonzord was able to fire missiles from its fingers and had a large drill on its tail that it could fight with.
