Power Rangers Ninja Thunder

Power Rangers Ninja Thunder was the first season to not feature "Thunderstorm". Its Sentai source was Ninja Sentai Kakuranger, which translated into Ninja Squadron Hidden Ranger. However, alongside Season 2, it did not use the Kakuranger suits for the core Rangers and were used for the Alien Ranger series instead. Much of the season was also heavily serialized, with multiple-part storylines sowing the seeds for events such as the Masked Rider television series, the eventual departure of long-running character Carmen Rodriguez and the events that would tie directly into the opening episodes of Ninja Thunder Alien Rangers.

During the last airing of this Season until Power Rangers Geo Force premiered, the "Today on Power Rangers" segments were replaced with the Geo Serial shorts.

Synopsis
Vita and Vito's cousin, Vida Vile comes to The Moon with strange eggs. She takes on the Power Rangers to impress her cousins, and destroys their Thunderzords, taking their powers with it. Telexa sends them to the Desert of Despair where they find Jinjor who, after some reluctance at first, grants them Ninja Powers as well as new Ninjazords. The Rangers continued their fight against Vita and Lady Morticia until shy new girl, Claire Mitchell, an gymnast/ex-diver comes to Riverside under Vita's spell. Carmen is captured by Goldonna but is eventually rescued by 15-year-old Susie Gold and the Rangers also gain the Shogun Zords. Claire later breaks free of Vita's spell and tells the Rangers everything. Carmen passes her powers to Claire but then comes Vita and Vito's parents, Master and Mistress Vile who wants to gain the power of the Geo Crystal. The Rangers thwarted that plan and one involving the singing Dischordia monster but Master and Mistress Vile's third plan basically stripped them of their powers, reversing the Earth's time back a few years and turning the Rangers into kids.
