The method for summoning Zords varies depending on the season of Power Rangers, but it usually involves the Rangers using a special device or calling out a command to activate their Zords. Here are some examples of how the Power Rangers summon their Zords:
Mighty Morphin Power Rangers: The Rangers would use their communicators to call for their Zords. They would say "Zordon, we need Dinozord power now!" and then their individual Zords would appear.
Power Rangers Zeo: The Rangers would use their Zeonizers to summon their Zords. They would say "Zeo Zord [number], activate!" and then their individual Zords would appear.
Power Rangers Turbo: The Rangers would use their Turbo Keys to summon their Zords. They would say "Shift into Turbo! [Zord name], power up!" and then their individual Zords would appear.
Power Rangers in Space: The Rangers would use their Astro Morphers to summon their Zords. They would say "Galactic Zords, arise!" and then their individual Zords would appear.
Power Rangers Ninja Storm: The Rangers would use their Storm Chargers to summon their Zords. They would say "Ninja Storm, Ranger form! [Zord name], power up!" and then their individual Zords would appear.
Power Rangers Dino Thunder: The Rangers would use their Dino Gems to summon their Zords. They would say "Dino Thunder, power up! [Zord name], arise!" and then their individual Zords would appear.
