* Creator/BarbaraHambly wrote one episode, "Traitors Three".
* Creator/GerryConway co-wrote nine episodes with his then wife Carla.
* KeepCirculatingTheTapes: It took a long time for the complete series to be (legally) released on DVD. However, Warner Archive released the first five episodes in December 2011, follwed up with 30 more episodes in July 2015, and finally completed the series in March 2016.
* OutOfOrder: "Man or Machine", the five-part MiniSeries introducing {{Sixth Ranger}}s Rex Charger and John Thunder, was run at the very end of the series, after all the other episodes featuring Rex and John had already aired.
* ScrewedByTheNetwork: During ''Centurions''' original syndicated run, several local stations dropped the show after a few months due to disappointing ratings. Also, many of the stations that kept it on the air gave it a less than desirable time slot, often 6:30 AM.
* WhatCouldHaveBeen: Plenty of it. ''Centurions'' went through an extensive development process, much of which has been revealed by fans who have contacted former Creator/{{Kenner}} employees and accessed the company's archives. While the basic premise (a PowerTrio of high-tech heroes representing LandSeaSky vs. a {{Cyborg}} MadScientist and his MechaMooks) was always there, the two early versions were both DarkerAndEdgier than the final series due to being set in {{Bad Future}}s.
** One early concept was titled ''[[https://static.tvtropes.org/pmwiki/pub/images/centurions_ring_of_fire_page_1.jpg Ring of Fire]]'', named after [[https://en.wikipedia.org/wiki/Ring_of_Fire a geographically unstable zone]] in the Pacific Ocean that includes a lot of volcanoes. The premise has these volcanoes simultaneously erupting one day, turning "everything west of the Rockies" into "one molten mass of lava rock". [[https://static.tvtropes.org/pmwiki/pub/images/centurions_ring_of_fire_page_3.jpg Dr. Sevarodd Rom]], whose research into "[[GeneticEngineeringIsTheNewNuke regenics]]" has allowed him to survive a near-fatal plane crash by merging with "a super computer brain" called Syntax, uses this devastated area as a base from which he sends his bots to "destroy all life forms". Opposing him are a military "[[https://static.tvtropes.org/pmwiki/pub/images/centurions_ring_of_fire_page_2.jpg tech team]]" of Case Kittredge (Army), Jim Earhart (Air Force), and AwesomeAussie Dixon Brown (Navy), whose abilities have been "intensified by exo-skeletal implants" thanks to [[HoistByHisOwnPetard Rom's own findings]].
** The next idea was "[[https://static.tvtropes.org/pmwiki/pub/images/centurions_united_we_stand_page_117.jpg United We Stand...]]". The villain (here called Half Mad) wants to steal Syntax (now a military super computer) and create "a perfect world where he would tyranically rule". To accomplish both goals, he tricks "the computer banks of the world's super powers" into launching missiles at each other; by the time anyone realizes the attacks are fake, "[[WorldWarIII The War of the Continents]]" is already underway. Afterwards, the nations of Earth create a benevolent OneWorldOrder to prevent another conflict, and Max, Jake and Ace are recruited as "[[https://static.tvtropes.org/pmwiki/pub/images/centurions_united_we_stand_page_28.jpg the 21st Centurions]]" to fight Half Mad's forces, resulting in [[https://static.tvtropes.org/pmwiki/pub/images/centurions_united_we_stand_page_3.jpg a format fairly close to the actual series]].
** [[https://static.tvtropes.org/pmwiki/pub/images/00000001.jpg This page]] shows that many other names were considered for the main PowerTrio, as well as [[https://static.tvtropes.org/pmwiki/pub/images/centurions_name_suggestions_page_2.jpg Doc Terror]]. Hacker could have been called Krusher ([[XtremeKoolLetterz yes, with a "K"]]) or Head-Splitter. Unused names for Rex Charger include Rex Powers and Storm Larsen. The Assault Weapon Systems also had some [[WorkingTitle working names]]; Wild Weasel was once known as Armordillo, Sea Bat might have been H[[superscript:2]]Go, Strato Strike started as Strato Streak, and Thunder Knife was almost called Slash Bash.
** And of course, the second year of the toy line was cancelled, so the planned figures of Rex and John (plus various other products, including most of the Assault Weapon Systems that were introduced in later episodes) were never made. Also, according to a 1987 Kenner Toys release sheet, if ''Centurions'' had continued, a [[SixthRanger sixth team member]] was "under consideration": [[https://centurions.fandom.com/wiki/Vic_McCloud Vic McCloud]], space specialist and Ace's (previously unmentioned) brother.
