History Series / PowerRangersZeo

* TheyWastedAPerfectlyGoodPlot: Tommy's family history. The only members of Tommy's family we ever meet are Sam and David Trueheart as well as his ancestor (who is also likely David's and maybe Sam's) The White Stranger from MMPR's season 2 Wild West episodes). His parents are mentioned in the Wild West Rangers episode of Series/MightyMorphinPowerRangers (Tommy's dad) and Found and Lost (both parents). They are never mentioned after that, even in situations where they should be (or at least mentioned again during the graduation ceremony in Series/PowerRangersTurbo)and when Tommy is unconscious during Series/PowerRangersDinoThunder. They are the only parents of MMPR season 1 Rangers who we never meet either partially or even in full without any explanation as to why either. We're also never told as to why Tommy and David are SeparatedAtBirth either.

* TheRez: The whole David Trueheart storyline.

''Power Rangers Zeo'' is the fourth season of ''Franchise/PowerRangers'' and a direct sequel to ''Series/MightyMorphinPowerRangers'', [[{{Frankenslation}} adapted from]] ''Series/ChourikiSentaiOhranger''. After the cliffhanger that ended the ''Mighty Morphin Alien Rangers'' arc, Rita and Zedd are busy celebrating their victory, only to [[ScrewThisImOuttaHere flee for their lives]] due to the invading Machine Empire, who want to gut Earth of its natural resources. Meanwhile, the Rangers have seemingly hit rock-bottom after the destruction of the Command Center and the loss of their powers. But thankfully, they find the incredibly-powerful Zeo Crystal amid the rubble; shortly after, they discover a new hidden base beneath the surface of the original. Zordon reveals that he and Alpha have survived, and to combat the threat of the Machine Empire, tap the Zeo Crystal to provide the team with all-new powers, including for the first time brand-spankin' new uniforms for the ''entire'' team.

''Zeo'' is largely where the franchise began to grow up, by introducing a few season-spanning plot threads, becoming ''slightly'' less preachy, with charity work and environmentalism becoming less common plot elements and much more character-driven. Billy Cranston, the last original Power Ranger, retired from active duty to act in a tech support and MissionControl role, as well as serving as a mentor to the newer rangers under Zordon. Newer characters such as [[{{The Ace}} Katherine Hillard]] and [[{{Shorttank}} Tanya Sloan]], and even [[{{Plucky Comic Relief}} Rocky [=DeSantos=]]] and [[{{The Quiet One}} Adam Park]], were allowed to grow beyond their SuspiciouslySimilarSubstitute beginnings. Even Farkus "Bulk" Bulkmeier and Eugene "Skull" Skullovitch managed some CharacterDevelopment after going through police training and later becoming private detectives. The show also reintroduced Jason Lee Scott, the original Red Ranger, to return and take up the role of their SixthRanger.

Unfortunately, ratings that had begun to decline in season 3 dropped even further in ''Zeo'', which lead to a harder cut-off to ''Zeo'' than expected. This season ends with the Machine Empire compromised but not destroyed and Lord Zedd declaring "We're back!" plotting their return. When ''Film/TurboAPowerRangersMovie'' came out the Machine Empire is not mentioned, Zedd and Rita only have a cameo (but implied they are not fighting the Rangers anymore) and the Zeo powers, weapons and zords are dropped entirely in favor of the Turbo powers and subsequent gear.

The infamous fan hoax "Scorpion Rain" was an attempt to bridge this gap, it was FanFiction claiming to be a multi-part MissingEpisode featuring [[EvilVersusEvil Rita and Zedd versus the Machine Empire]] on the moon and Serpentera ends up buried. The story was placed retroactively into continuity with the ''Series/PowerRangersWildForce'' episode "[[MilestoneCelebration Forever Red]]", although only in BroadStrokes. WordOfGod regarding Zedd and Rita is they took a honeymoon to raise their child Thrax, who appears in ''Series/PowerRangersOperationOverdrive''.

* EarlyInstallmentWeirdness: The first time the Rangers go into battle, they morph by bringing the two halves of their Zeonizers together and yelling "Power Rangers! Z! O!" Every time after that they instead say "It's Morphin' Time!" just like in MMPR.

''Power Rangers Zeo'' is the fourth season of ''Franchise/PowerRangers'' and a direct sequel to ''Series/MightyMorphinPowerRangers'', adapted from ''Series/ChourikiSentaiOhranger''. Rita and Zedd have been reduced to homeless rovers on what was once their moon kingdom due to the invading Machine Empire, who want to gut Earth of its natural resources. The Rangers are briefly left powerless after the destruction of their command center. But thankfully, Zordon reveals that he and Alpha have tapped into the mighty Zeo Crystal and they have produced brand new ranger powers, including for the first time brand-spankin' new uniforms for the ''entire'' team.
