* ChannelHop: How the producers got away with a lot of the season's FamilyUnfriendlyViolence. They told the first network ({{Fox}}) that Cole's parents would've later turned out to be alive. They then "neglected" to tell the second network (Disney) that the death had ever happened, so they didn't have to keep the promise, and they stayed dead.
* DawsonCasting: Max is supposed to be a lot younger than the others even though he's played by an actor the same age as the rest of the actors. [[OlderThanTheyLook It's a little hard to tell, though.]]
* ExecutiveMeddling: Apparently, Forever Red was going to be a two-part episode that would have ended with the rangers summoning their respective megazords and taking down Serpentera together. Disney however did not like the idea of spending money to create the CG zord footage as they didn't have toys to promote and told them to cut it into one episode as the team-up was just expensive in general.
** More meddling came from Bandai, the company that produces Power Ranger toys. After Disney refused to fund Forever Red, the writers asked Bandai for money. They agreed, but only if the episode promoted the Wild Force Rider toy, which is why Serpentera, Lord Zedd's most powerful super weapon, gets taken out by a motorcycle...
* HeyItsThatVoice: [[Anime/DigimonAdventure Gennai and Zudomon]] lend their voice to two of the [[MonsterOfTheWeek monsters of the week]]. Zen-Aku is voiced by two different people during different parts of the season: first [[VideoGame/GhostsNGoblins Ar]][[MarvelVsCapcom3 thur]], then [[VideoGame/DigimonAdventure WarGreymon]].
** Also, some of the generals in "Forever Red" were voiced by previous Rangers, with [[Series/MightyMorphinPowerRangers Zack]] as Gerrok, [[Series/MightyMorphinPowerRangers K]][[Series/PowerRangersZeo a]][[Series/PowerRangersTurbo t]] as Tezzla and [[Series/PowerRangersLostGalaxy Kai]] as [[NamesTheSame Venjix]].
* NamesTheSame: The lead general of the Machine Empire in "Forever Red" is named Venjix, which is later used as the name of the main villain in ''Series/PowerRangersRPM''.
* TheOtherDarrin: For clarification, Zen-Aku was viced by Dan Woren before being replaced with Lex Lang.
* PromotedFanboy: Prior to joining the staff of the show (and writing the episode "Forever Red"), Amit Bhaumik managed a popular ''PR'' fansite, the ''Power Rangers Online Archives''.
* PropRecycling: Most of the Machine Empire stuff in "Forever Red" was taken from ''{{Beetleborgs}}''.
** Master Org's costume was reused (or at least heavily inspired) from the BigBad of ''Series/GoseiSentaiDairanger'', who was replaced with Zedd when brought over as part of ''Series/MightyMorphinPowerRangers''.
** One of the Mutorgs from "Reinforcements From The Future" was Deviot's monster form from ''Series/PowerRangersLostGalaxy'' recolored. (They were originally going to use the Orgs from the Gaoranger movie, but they were lost in a fire.)
* WhatCouldHaveBeen:
** There are officially 100 Power Animals, but we only ever see 22. Toei actually designed and detailed about a dozen more exclusively for ''Wild Force'', including a peacock with many weapons as its tail feathers and a wallaby with a baby in its pouch. These can be found in the artbook ''Super Sentai Robot Art Collection''.
** Forever Red was originally going to be two parts, though it was forced to become only one part thanks to the fact that another crossover, Reinforcements From the Future, happened recently, not to mention that it was two parts long. Many things were cut out of Forever Red, most notably the original fight with Serpentera.
** Much of the ShipTease in this season was supposed to have an actual payoff, with Danny going back to the flower shop with Kendall and Cole and Alyssa being married in a DistantFinale.
** In addition to Cole's parents being brought back to life, another idea was that the attack by Master Org that "killed" them actually brainwashed them into become Jindrax and Toxica.
** According to the Ranger Wiki, Kendall was going to become a ranger at some point. It's unknown if she was going to be an American exclusive ranger, or a replacement ranger though.
