Thunder Megazord (Mighty Morphin)

In forming the Thunder Megazord, the Red Dragon in Warrior Mode formed the internal structure and wore the other Thunderzords like body armor, (similar to the formation of the original Megazord) making it look like a samurai. The Lion formed the main arms (gloves and shoulder pads), chestplate, and helmet. The Griffin and Unicorn formed the main legs. And the Firebird wrapped itself around the waist forming skirt-like lower torso armor. Unlike the original Megazord, the power-crystals weren't needed to transform the Thunderzords. While piloting the Thunder Megazord, the Rangers would stand inside the cockpit located within the green window on the Megazord's chest. It was also called the "Mega Thunderzord" at times.

The Thunder Megazord's main weapon was the Thunder Saber, which hung in a sheath on its hip while not in use. Like the original Megazord's Power Sword, it also delivered an energy slash as a finisher. Another one of its weapons was the green window on its chest, which could unleash a smokescreen that could cause damage. In Dairanger it also had a speared polearm which combined the Firebird's tail with the Red Dragon's staff, which it was cut out from the Power Ranger episodes, but was included in the American toy versions.

The Thunder Megazord is one of only 2 Megazords to have its main weapon used against it. In the episode "Orchestral Maneuvers in the Park", the Trumpet Top monster used the Thunder Saber to inflict damage on the Megazord (The other was the Mega Winger from Power Rangers in Space; Psycho Pink used the Wing Blaster against it). The Thunder Megazord is also the first Megazord to have an American-made cockpit, the only others in the entire franchise being its successors, the Ninja Megazord and Shogun Megazord, as well as the Titanium Ranger's Max Solarzord in Power Rangers Lightspeed Rescue, as the Titanium Ranger is solely an American-made character.
