Mighty Morphin Power Rangers (Season 2)

Plot
Angered at the repeated failures of his servant Rita Repulsa, the evil emperor Lord Zedd arrives and overthrows her. He then begins to attack the Power Rangers with Pirantishead, a stronger monster than the Rangers are used to fighting. Pirantishead freezes four of the Dinozords and takes control of the Tyrannosaurus Dinozord and the Dragonzord. Because of this, the Rangers are required to upgrade their Dinozords into more powerful Thunderzords, which can combine to become the Thunder Megazord. After doing so, they defeat Pirantishead and give Lord Zedd his first defeat.

As he continues to fight the Rangers, Lord Zedd decides to destroy the Green Ranger Tommy Oliver with a special Green Gem designed to take away his powers permanently. Though the Gem is eventually destroyed, it is too late to restore Tommy's powers. However, Zordon gives Tommy new strength in its place -- the power of the White Ranger.

The Rangers later make some new friends in Rocky DeSantos, Aisha Campbell and Adam Park, who also discover the Rangers' identities. When Jason, Zack and Trini are selected to go to the Peace Conference in Switzerland, the Rangers are required to find three replacements for them. They travel to a deserted planet to retrieve the fabled Sword of Light required for the Power Transfer, but Lord Zedd introduces Serpentera, his gigantic personal Zord. While powerful, Serpentera's massive energy consumption proves to be its undoing. The Sword is retrieved and taken back to Earth, where the retiring Rangers name Rocky, Aisha, and Adam as their successors.

Eventually, Lord Zedd proves no more successful than Rita was, but he does not give up as he undergoes a Centennial Recharge. Rita Repulsa chooses this time to return to the moon and slip a love potion into Zedd's Rejuvenation Chamber. When he wakes up, Zedd is madly in love with Rita and marries her. With both Zedd and Rita together, the Power Rangers are faced with even more terror.

Production
Saban was originally to produce only 40 episodes in the series, ending with the two-parter Doomsday. Another character was to make an appearance, named Bubba. As the episode was originally written, he piloted Cyclopsis, and was based off of Kai in Zyuranger. After Cyclopsis' defeat at the hands of the Rangers, Bandora would be sealed away in an urn (mimicking the ending of Zyuranger), and the teenagers would give up their powers then go to senior prom, which indicated that the team would've all been 17-18, as opposed to 14-15.

However, due to the unforeseen popularity of the series, Saban, the company that produced Power Rangers, was faced with the possibility of exhausting all of its Zyuranger footage with no more to fall back upon in order to continue producing the show. The company decided not to age the Rangers that much and contacted Toei (the company which produced/produces the Sentai series in Japan) as well as Rainbow Productions (the company that designed and produced the monster suits), requesting another half-season's worth of Zyuranger footage...specifically for Power Rangers. The two Japanese companies agreed, creating around 25 brand-new monsters and filming both human- and zord-sized battle footage for each, as well as incorporating elements from MMPR into the footage (a relationship between the Green and Pink Rangers, and the Blue Ranger as the brains of the group being the most obvious examples). This footage of monsters are collectively known in the Power Rangers fan community as "Zyu2".

Around this time, Saban was also negotiating a deal with Toei to acquire footage from Gosei Sentai Dairanger, the sentai series which followed Zyuranger. Saban used more than half of the Zyu2 footage in the remainder of Season One of Power Rangers, but when they decided to replace the Dinozords with the mecha from Dairanger in Season Two (termed Thunderzords in Power Rangers), the Zord footage of the remaining Zyu2 monsters became obsolete. To compensate for this, Saban attempted to splice the Zyu2 and Dairanger footage to ensure that the Zyu2 monsters were fighting the Thunder Megazord instead of the Dino Megazord. The new scenes would show only the monster attacking, followed by a shot of just the Thunderzords taking the damage. It did not always work, for occasionally the monster could actually be seen making physical contact with the old Megazord.
