When the Power Rangers are going up against a new adversary, there are two stages to defeating their foe. The first is defeating the monster/alien on the ground with their fighting skills and weapons. Then once said monster/alien starts terrorizing humanity as a giant, then the Rangers call upon their Zords, mechanical vehicles that can come together to form the Megazord. We've seen glimpses and quick shots of the Zords in Power Rangers marketing material, but a new poster for the upcoming reboot provides the best look yet at the mighty beasts.
Just like in the 1990s Mighty Morphin' Power Rangers TV series, the new versions of the original teenagers with attitude will be piloting Zords based off dinosaurs and other prehistoric creatures. Along with the Rangers themselves in the new Power Rangers poster, we have Jason the Red Ranger's Tyrannosaurus Rex, Trini the Yellow Ranger's Sabertooth Tiger, Billy the Blue Ranger's Triceratops, Kimberly the Pink Ranger's Pterodactyl and Zack the Black Ranger's Mastodon. For longtime Power Rangers fans, the only thing missing from the lineup is Tommy the Green Ranger's Dragonzord. Tommy won't appear in Power Rangers, although if the Green Power Coin in Rita Repulsa's staff is any indication, he and his Zord are being set up for introduction in the sequel.
Like the Rangers' suits, Zordon and Alpha 5, Power Rangers' versions of the Zords have been radically altered to look more alien. You can still tell that they resemble animals that lived on Earth thousands-millions of years ago, but the similarities aren't nearly as noticeable as they were on Mighty Morphin' Power Rangers. While the Zords are powerful enough individually, it's when they're assembled together as the Megazord, which is a humanoid robot akin to Jaegers from Pacific Rim and other types of mechas.
As seen in the most recent Power Rangers trailer (which you can re-watch below), the Rangers will use their Zords to battle Rita Repulsa when she's unleashed Goldar, who isn't a winged ape demon wearing gold armor in this continuity, but a gargoyle-looking monster Zord made out of pure gold completely subservient to Rita. According to reports, Goldar is the only one capable of breaking through to the Zeo Crystal, the artifact that protects the Morphing Grid, which gives the Rangers their power. It looks like the battle with the gigantic Goldar will be Power Rangers' climactic conflict, and if the morphenomenal superheroes don't stop him and Rita with their Zords, they'll be destroyed and the Earth will be at the mercy of these villains. No pressure or anything.
You can see the re-imagined Zords in battle when Power Rangers morphs into action on March 24.
