Rangers of Two Worlds

Rangers of Two Worlds is the forty-seventh and forty-eighth episodes of Power Rangers Zeo. It is a team-up between the Zeo Rangers and the Alien Rangers and the final physical appearance of Billy Cranston in the Power Rangers franchise; despite no appearance by his original actor David Yost due to previously departing over staff issues regarding his sexuality.

Synopsis
Billy is rapidly and uncontrollably aging, King Mondo has unleashed Cog Changer to steal the Zeo Megazord, and Rita Repulsa has created an invincible monster. The Zeo Rangers must once again join forces with the Alien Rangers of Aquitar to deal with these multiple situations.

Part I
At the Juice Bar, Kat is moaning over the ugly-looking pink purse she had made in Art class. Adam and Tanya attempt to cheer Kat up, which somewhat works, until Jason arrives and asks them to come with him and Rocky immediately. Nearby, Bulk and Skull are studying for the exams to earn their detective licenses, with Detective Stone pressuring them on.

Arriving at the Power Chamber, the Rangers meet with Tommy, Alpha 5, and a strange man... who introduces himself as Billy. Seeing his friends confused, Billy recounts when Master Vile reversed time and turned them into children. He had used his Regenerator device to restore himself to his normal age before it was destroyed, but now its side-effects are causing him to age very rapidly. Not even Zordon is able to find a solution to Billy's condition, but Billy seems to have an idea...

In the Machine Moon Base, Queen Machina is ecstatic to be reunited with King Mondo after his lengthy repairs, while Prince Sprocket informs his father of Gasket's attempts to steal the Empire in his absence. Listening in from a hideout on Earth, Gasket and Archerina are less-than-pleased at Mondo's plans to punish them and decide to flee the planet for now.

Back at the Juice Bar, Kat and Billy are pouring through the Lost & Found in hopes that someone found any other of Billy's devices, but there aren't any there. Billy does find Kat's ugly purse (much to her disappointment), plus a whistle which proves handy in getting an eavesdropping Bulk and Skull off their backs.

Elsewhere on the Moon, Rita Repulsa has received a new, more powerful magical staff from Finster, and she gets the idea to use the staff to bring Kat back to her side as a villain. While the RV drives into position for the shot, Rito Revolto and Goldar squabble over seats and accidentally makes Lord Zedd drive the vehicle off-course as Rita fires her staff, causing the shot to instead hit Kat's ugly purse and turn it into a new monster -- The Impursonator. Not one to be outdone by their efforts, Mondo sends out his most powerful creation yet -- Cog Changer.

Back at the Power Chamber, the effort to find a solution to Billy's problem is no more successful, and Billy has begun to age further. Fortunately, two familiar friends arrive to help: Delphine and Cestro of the Aquitar Power Rangers. The Alien Rangers attempt to restore Billy using a Regenerator of their own design, but the device backfires and takes out the teleportation unit. Though Delphine and Cestro will repair the device, they need very fresh water for it to work. Rocky suggests going to Angel Grove Falls, and Billy recommends that they take the Zeo Jet Cycles.

The alarm suddenly sounds as both Mondo's and Rita's monsters are detected. Jason decides to go to the Falls to get the water while the Zeo Rangers morph into action. As they ride to battle, Cog Changer appears and hits the Bikes with remote devices, causing them to go out of the Rangers' control and crash into an abandoned shack containing fuel drums. The Rangers quickly leave before the fuel drums explode, destroying the shack and the Bikes. Mondo then arrives with a Cog army to pound on them further, but the fight is quickly interrupted when Rita and Zedd enlarge Impursonator to steal Mondo's glory.

The Zeo Megazord is summoned to fight the larger threat, but all of its attacks prove unable to beat the beast's blubbery body and electrical counterattacks. The Red Battlezord joins the fight and pushes Impursonator back, while Mondo orders Cog Changer to secretly send an evil cog into the Zeo Megazord. The Rangers are kept unaware of the sabotage as they form the Zeo Megabattlezord, bring Jason's Gold Ranger powers into the battle with Pyramidas, and even launch the Zeo Ultrazord, but Impursonator resists and counters everything thrown at her. The Rangers are ultimately forced to retreat, but Rita and Zedd's victory is ruined when Mondo teleports their monster to another planet out of spite. He then boasts that thanks to Cog Changer's sabotage, the Zeo Megazord will destroy the Rangers the next time it's activated.

Back at the Power Chamber, the repaired Regenerator is used but fails to have any effect on Billy. Between this failure, Cog Changer on the loose, and Impursonator still a threat, the situation is indeed dire. Regardless, the Alien Rangers pledge to help in any way possible.

Suddenly, Zordon picks up a reading in the Zeozord holding bay, specifically inside the Zeo Megazord. Disregarding concern over his condition, Billy goes inside the Zeo Megazord to investigate and run a system check, only to become trapped when the evil cog activates the Megazord and makes it fly out of the holding bay.

Part II
With the Zeo Megazord on a rampage and Billy still trapped inside, the Rangers try to repair the damaged teleportation unit so as to get him out of danger. The targeting systems are still offline, making a precision teleport from within the moving Megazord impossible, and so the Rangers launch the Super Zeo Megazord to hold it in place long enough to get a lock. Thanks to Cestro's "unique" repair methods, Alpha is able to lock on and teleport Billy back to the Power Chamber.

Zordon reports that Cog Changer has commandeered the Zeo Megazord, his prior sabotage allowing him to bypass the defense mechanisms, and the Rangers are forced to fight it off with the Super Zeo Megazord. Meanwhile, Billy has aged even further. At Alpha's calculations, he'll reach age 100 within the next hour.

On the Moon, Rita is jealous at Mondo's monster turning a Megazord against the Rangers, while Zedd is merely apathetic. Finster, however, reports that Impursonator is already on her way back to Earth. Her arrival comes as a complete and literal shock to the Rangers, as she teleports into the Super Zeo Megazord and ejects them before turning her attention to Cog Changer. As the two Megazords begin tearing through Angel Grove, Bulk and Skull are beginning their detective license exams. They assume that the alarms, earthquakes, and sounds of destruction are part of the exam, so they ignore the chaos even as the office collapses around them.

With limited options, Jason summons Auric the Conqueror in order to stop the fighting, but Auric's attempt at a peaceful resolution between the Megazord-piloting monsters backfires when Impursonator banishes him away. On Sprocket's suggestion, Mondo then adds injury to insult by sending Cogs to kick the Rangers while they're down.

After a short fight, the Rangers return once more to the Power Chamber. Delphine reports that there may yet be a way to save Billy. She tells them of the Eternal Falls, a mystical source of water which keeps her people young and healthy, but Cestro warns that its effects on humans are unknown. Billy is willing to take the risk and has asked that a friend of his from Aquitar, Cestria, bring him some of its water. Delphine also reports on an observation she made about Impursonator: it's easily distracted, leading Kat to come up with a plan.

Tommy, Adam, and Rocky arrive to taunt Impursonator, who takes the bait and abandons the Super Zeo Megazord to fight them. Rita instead pulls her monster out of battle to scold her for such a costly mistake. Meanwhile, Tommy, Adam, and Rocky take back the Super Zeo Megazord and hold Cog Changer back while the girls slip into the Zeo Megazord and destroy Cog Changer's evil cog before ejecting the unwelcome pilot. At the Power Chamber, Cestria administers to Billy the water from the Eternal Falls, which briefly works but fails to have any lasting effect. It's decided that Billy must go to Aquitar for extensive treatments, and Billy asks Jason to tell the other Rangers of the news as he and Cestria teleport away.

The alarm sounds as Cog Changer and an army of Cogs converge on Angel Grove Colosseum, along with Impursonator. As Jason heads back to action, the entire team of Aquitar Power Rangers join him to unite with the Zeo Power Rangers, sparking an enormous battle royale between Rangers and monsters. As the Cogs are dispatched, Klank and Orbus arrive to enlarge Cog Changer, while Rita and Zedd cross their staffs to make Impursonator grow. The Zeo Rangers bring in the Super Zeozords to deal with the giants while Jason and the Alien Rangers finish off the remaining Cogs.

Sprocket then hits on the idea to make both monsters fuse together, creating the Cog-Impursonator. The Super Zeo Megazord is formed, and the Zeo Megazord, Red Battlezord, and Warrior Wheel are summoned to join in. Together, the two Megazords and the Red Battlezord throw the Warrior Wheel among them and trap the fused monster in the middle of the energy vortex they create, weakening Cog-Impursonator enough for the Warrior Wheel to destroy it in a final strike.

The next day, Bulk and Skull get their exam results from Det. Stone. Though the pair are initially happy that they passed, Stone informs them that they would've failed had they not gotten extra credit for working through a monster attack, and their moods quickly drop. In the Power Chamber, the Zeo Rangers receive a message from Billy on Aquitar, who looks and sounds much more like his normal age again. The Rangers ask when he's coming home, but Billy explains that he intends to stay on Aquitar with Cestria, feeling that it's the place where he belongs.

Errors

 * Both the Power Rangers and the Machine Empire seemed to suddenly be aware of Rita and Zedd's return.
 * When the Rangers jump into their Zeo Zords they do so with a teleportation sound. Not only was the teleportation system explicitly stated to be down, but this noise had never been heard during the many previous instances that the Rangers entered their Zords.
 * The Rangers didn't think to summon the Super Zeozords or the Warrior Wheel during their near-disasterous battle against Impursonator.
 * When the alarms in the Power Chamber went off for the first battle, they sounded more like the old Command Center alarms.
