- "Gosei Great Megazord, ready!"
- ―Mega Rangers announcing the complete transformation
Gosei Great Megazord is the first Megazord used by the Megaforce Rangers in Power Rangers Megaforce, a combination of the five Mechazords. The rangers utilize this Megazord against Vrak in Power Rangers Super Megaforce.
The rangers ready their Gosei Mechazord cards that read 'Gosei (whatever their zord is called)". The rangers activate them, summoning their Mechazords. The Rangers lock their morphers onto the zords' dashboards once entering the cockpits.
When combined the Rangers teleport to a more central cockpit using the same teleportation technology Gosei uses for transport.
It's able to fire its Zord component heads like projectiles to execute the Multi Zord Attack, and control to execute the Mega Punch and the Mega Kick. The Gosei Great Megazord is armed with a large sword that it uses to execute the Mega Strike slash attack.
The Gosei Great Megazord was always part of the Mega Rangers battle system. However, they didn't use their Mechazords until their encounter with Yuffo. They had defeated Yuffo with Megaforce Blaster's Victory Charge. However, Vrak's Zombats arrived and made him giant-sized. With his power to separate into saucer sections, Gosei told the Rangers to call on their Mechazords for battle.
After Vrak managed to turn the Rangers' Legendary Ranger Keys to stone, cutting them off from the use of the Legendary Megazord, they employed the Gosei Great Megazord again in order to do battle with Vrak's minions. They would later summon the Mechazords again in their final battle using Zords against the Armada, but were defeated; it is unknown whether or not the Mechazords were destroyed.
