In the year 1992, a Japanese space mission to the planet Nemesis led to the accidental release of Bandora and her minions. Seeking to pick things off where they left off, Bandora launched a full-scale assault on Tokyo. This prompted Barza to revive the warriors of the five tribes to put a stop to her. Brought up to date on what was going on, the five were given Dino Bucklers they could become the Zyurangers, avatars for the Guardian Beasts on Earth and the only force powerful enough to oppose Bandora. Mei became the Pink PteraRanger, and was under the command of Geki. Their primary mission was to save the lives of two children who were kidnapped from the space mission by Bandora. This led to battles against two of Bandora's creations, the Dora Monsters known as Dora Skelton and Dora Titan. Ultimately the monsters fell thanks to their new powers and abilities. Dora Titan, in particular, fell when Geki summoned the Guardian Beast Tyrannosaurus to destroy the gigantic monster. With her initial attack on Earth a failure, Bandora was forced to retreat to the Moon where she launched subsequent attacks on Earth and the Zyurangers.
