Power Rangers Zeo

Power Rangers Zeo is an American television series and the fourth season of the "Power Rangers" franchise, based on the 19th Super Sentai series "Chouriki Sentai Ohranger". It is the continuation of "Mighty Morphin Power Rangers", which aired in year 1996.
"Power Rangers Zeo" is also the first season of "Power Rangers" to follow the Sentai practice of annual Ranger suit changes and also the last series to use "it's Morphin' Time" until the Saban Brands era of Power Rangers returned with it as a pre-start command starting with "Power Rangers Megaforce".
Plot.
After witnessing the destruction of the Command Center, the powerless Rangers discover the Zeo Crystal intact in the rubble—apparently dropped by Goldar and Rito Revolto. The Crystal guides them to a portal, which takes them deep underground to the Power Chamber where they find Zordon and Alpha 5 waiting for them. The Mighty Morphin Power Rangers become the Zeo Rangers, a new team of Rangers powered by the Zeo Crystal. The four remaining Mighty Morphin Power Rangers, Tommy Oliver, Adam Park, Rocky DeSantos and Katherine Hillard become Zeo Ranger V — Red, Zeo Ranger IV — Green, Zeo Ranger III — Blue and Zeo Ranger I — Pink respectively and Tanya Sloan joins the team as Zeo Ranger II — Yellow, while Billy Cranston chooses to become their technical advisor rather than continuing as a Ranger.
The Machine Empire, led by King Mondo and Queen Machina, enters Earth's solar system, seeking to conquer Earth, with the Zeo Rangers serving as the only opposition. Many, even Rita Repulsa and Lord Zedd, are forced to flee to the M51 Galaxy under the threat of destruction. Unbeknownst to anyone, Rito and Goldar – now amnesiac – are left behind on Earth. They are taken in by Bulk and Skull, who have them serve as butlers. Meanwhile, Bulk and Skull continue to be members of the Junior Police Force until Lt. Jerome Stone is dismissed, when Bulk tries winning the heart of the chief's daughter. Quitting as a show of respect for Stone, they join him at his new detective agency.
Over time, the Machine Empire wears down the five Zeo Rangers, but they are rescued by the mysterious Gold Ranger. Though his identity is unknown, it quickly becomes clear he is there to help the Rangers. After he is injured in battle, it is revealed that the mysterious Gold Ranger is an alien, Trey of Triforia. Split into three separate selves, Trey is forced to temporarily pass his powers to a worthy warrior while healing. They attempt to transfer Trey's powers to Billy, but as Billy acquired excess negative energy during the Command Center's destruction, he is unable to do so. The ultimate successor is Jason Lee Scott, the original Red Power Ranger and team leader. This event also sees the introduction of the more powerful Super Zeo Zords, which were used against a tougher generation of machines. The Super Zeo Megazord is powerful enough to later destroy King Mondo, creating a power vacuum in the Machine Empire.
Secretly returning from the M51 Galaxy, Lord Zedd and Rita seek to become top villains again. Operating out of an RV with Finster, they restore Goldar and Rito's memories, retrieving the pair in the process. After King Mondo's death, they launch their first plan, to use Louie Kaboom to take over the Machine Empire. Though he succeeds, he breaks free of Zedd and Rita's control. He embarks on his own plans to conquer Earth and destroy the Zeo Rangers. Louie is eventually killed by King Mondo's first-born son Prince Gasket and his wife Princess Archerina, who rule until King Mondo's reconstruction is complete, which causes them to flee.
When Billy begins rapidly aging as a side-effect of restoring his proper age before undoing Master Vile's spell in the last series, the Zeo and Aquitian Rangers race to help him and fend off monsters from King Mondo as well as Zedd and Rita. Billy leaves Earth for treatment on Aquitar and chooses to stay to be with Cestria. Soon after, it is discovered the Gold Ranger powers are leaving Jason and draining his life force in the process as the alien powers were not meant for a human. Trey is still in recovery, but a risky gamble with the Zeo Crystal heals him, restoring his powers. Rita and Lord Zedd finally get revenge on the Machine Empire by crippling their leaders with a bomb.

Villains.
Machine Empire.
Machine Empire Monsters.
The monsters of this show are robots created by the Machine Empire. They are adapted from the monsters featured in "Chouriki Sentai Ohranger". To make a monster grow, Klank would swing Orbus around until he latched onto the monster emitting an energy that would enlarge the monster.
Besides some of the monsters listed above, some of the monsters from the last season made cameos in the two-part episode "King for a Day" as members of the Machine Arena's audience. They consist of:
Identity of the Gold Ranger.
During the middle of the series, the identity of the Gold Ranger was a constant teaser and a central plot theme. After many episodes of speculation, with other characters like Billy Cranston, David Trueheart, and even Eugene Skullovitch suspected, it was revealed the Gold Ranger was Trey of Triforia, a new character. Former Red Ranger, Jason Lee Scott, obtained the powers of the Gold Ranger after Trey lost the ability to transform. Actor Brad Hawkins, who played Ryan Steele on "VR Troopers", voiced the Gold Ranger early on. Saban had supposedly planned to use him after the end of "VR Troopers" as Ryan and put that series into the continuity of "Power Rangers". However, for unknown reasons (believed to be scheduling conflicts), he was not used as the identity of the Gold Ranger, and instead Ted, Tim and Tom DiFilippo portrayed the three parts of Trey.
Home media releases.
Starting in August 1996, several episodes of "Power Rangers Zeo" were released on VHS.
In 2012, Shout Factory announced that it had reached an exclusive distribution deal with Saban for shows such as "Power Rangers" and "Big Bad Beetleborgs". "Power Rangers Zeo" was released on DVD in August 2012, as part of a Time-Life exclusive boxed set containing seasons 1–7. The show later became available independently of the boxed set in two volumes, each containing 25 episodes.
Comics.
Image Comics began publication of a "Power Rangers Zeo" comic in August 1996. It featured scripts by Tom and Mary Bierbaum, and art by Todd Nauck and Norm Rapmund. Four issues were drawn but only one was released before Image Comics lost the license.
During the events of "Shattered Grid," the Zeo Rangers existed in their own bubble of reality and are seen fighting the Machine Empire. Upon further revelation, it is revealed that Lord Drakkon has taken Tommy's place and is holding him hostage. He steals Adam's Zeo Morpher to use the Green Zeo Powers to create more soldiers for his army, and slits Tommy's throat before leaving the Zeo Rangers' world. Later, Katherine, Tanya, Rocky, and Jason are summoned from their universe to fight the forces of Drakkon, with Adam being left behind in their world due to the corruption of his Green Zeo morpher.
It has been revealed that Tanya will join a team of rangers formed across the various universes in the follow up to "Shattered Grid" in "Beyond the Grid," alongside the Ranger Slayer, The Magna Defender, Andros, Cameron, and the as of yet unrevealed Dark Ranger.
