The battle between the Mighty Morphin Power Rangers and the Evil Space Aliens led by Lord Zedd and his wife Rita Repulsa continues as both sides gain new allies and powers. Rita's brother Rito Revolto arrives bearing new minions in the form of Tenga Warriors, and he also destroys the Rangers' Thunderzords and powers as part of a cunning trap. Zordon sends the Rangers to the Desert of Despair to meet with Ninjor, a legendary warrior who grants them Ninja Powers and new Ninjazords. Big changes also come to the long-suffering Bulk and Skull when they join the Angel Grove Junior Police Patrol and meet with their new boss, Lt. Jerome Stone.
