I can explain most of this. The time slot is flexible, and it might be better if they did this when all they have is syndication on the air. If you have a superfluous show on at night, then there is justification and little conflict with "fun in the sun". Second, the older teams are only partial to the idea. I'm referring to EVERYTHING FROM 20 YRS OF P.R. HISTORY. This could encompass anything: History of Zordon and Gosei, Vekar and Vrak prior to the Invasion, the unexplained interim between Zeo and Turbo, the fate of Scorpina, Rito Revolto, Gasket and Archerina, the backstory to the Machine Empire Generals from "Forever Red", when did Zedd and Rita have Thrax, possible Scorpius and Captain Mutiny interaction, why Ninjor made Power Coins based on DINOSAURS!!! I could probably say more, but if you take all of that, then you have a whole different story worthy of its own series, and there likely isn't a better way than a "sister series" to explain why Pre-Zyu teams are in P.R. That is where the nostalgia factor kicks in! That is why and how you can garner fan support! If TV movies and online shorts are required then there is some flexibility there as well. And the competition between toys would not be so detrimental that you can't work around it. Remember, Saban already did competition back in the day with VR Troopers, Beetleborgs, and Mystic Knights. Plus, Bandai already did similar "Legacy" things before and now. "Power Playback" lines, Retrofire Megazords, and the upcoming and highly anticipated Legacy Thunder Megazord. And Super Megaforce toys are still on shelves if only in small doses. It wouldn't even have to be called "Power Rangers _____", as that would confuse people. The show and the line would need something unique, but simple and definitive like "Legacy of Rangers." However, Saban would only recognize the need if fan support was strong enough, and luckily, there is a buck to be made when thinking P.R.

P.S.: I had NO INTENTION of relying solely on outdated Sentai footage. Changeman, Flashman, Maskman, Fiveman, and Dairanger were made when TV ratios were different. Ever seen Dragon Ball Z Kai on Toonami? That and the age would conflict horribly. The benefit here is that four of the five had movies which MIGHT have been done in widescreen, and that is something to consider. Add that with unused Gokaiger footage and some New Zealand shoots and there might be a chance. The rights to the movies, like the 199 Hero Special, would also be beneficial and necessary. I'm also not saying that the teams would appear every two seconds. They should (and would have to) be used rather sparingly, but when focus should happen, IT SHOULD HAPPEN IN FORCE!!!

But Toku Knight, any of this idea would not be made, there is no nostalgia. Sure it's cool to know that there were sentai out of Zyuranger, but that's it. Zyuranger became the original Mighty Morphin, people grew up with that, but there is nothing with Pre-Zyu. Dairanger has some nostalgia, if only for the Megazord Footage.

Although the only way for your idea to come to light would probably be through Boom! They are now doing comic books for Power Rangers, but still that chance is like smaller than an atom.

There is nostalgia in fan debate. 20 yrs. of history prior to Super Megaforce, then we had to unbearably look at Pre-Zyu in Super Megaforce; shoe-horned in without detailed explanation as to why. That is what I am truly getting at. People showed some enormous aggravation at the Pre-Zyu Inclusion during the "Legendary Ranger Mode" changes, and some thought that they should be given greater detail. Dairanger was the first as "New Powers". Here is a mere consideration as how to handle that "greater detail". Pre-Zyu is only one singular, microscopic detail compared to the greater whole, and the greater whole is what I want to defend. There is definitely a certain naivety in my stance on the matter, but that does not change its validity. Super Megaforce made mistakes, but that can be corrected and all the confusing elements from Mighty Morphin' through Super Megaforce can be jumbled together to create newer episodes. While they would be traditionally standalone pieces, they would loosely come to together with each build-up to create an interwoven tapestry and all the questions all the fans have asked over the past two decades can finally have a chance at not only being brought to the surface, but settled in an acceptable and respectable manner; no single cast, no single team, no single focus.

TokuKnight, I get what you are trying to say, I really do, but doing something like this would still cost money and without merch to make that money back, there is no reason to go on this venture. That is exactly how Saban Brands would respond while also saying that it is a cool idea.

Having the show on late defeats the purpose of it being a kids' show. That would aim toward the adult demographic and I am sure that Nick would not air it. They just wouldn't. If this stuff went online (where Saban and nick could sell the advert dollars to help fund it) that could be more realistic, but it still wouldn't make enough to justify it's production.

And VR Troops, Mystic Knights, and those other toku shows that Saban did weren't direct competition to Power Rangers. They were all different shows that appealed to different audiences. That is why only one of those is still on the air. Even in Japan, those shows don't/didn't compete because they attract different audiences and are marketed to different audiences.

The Legacy line is marketed to adult collectors, the main toy line (that gets a wider release and at a much more affordable price point) is where the vast majority of the toy money comes from. Look at it this way; there are tons of people that want to collect all the figures and zords from a season. Those are released across two years. A person spends more on buying five rangers, the main megazord, the villain figure, and the henchman than they do on one TRU exclusive megazord. That is why Legacy line toys are sparsely released whereas main line toys are hammered away over the course of 24 straight months.

And starting a legendary line of toys wouldn't garner as much money as you think. Five teams of rangers (20 figures) four megazords (if they even do those since they weren't seen in the show...they could just say it was before megazords were a thing), and potential for figures of the villains and allies during the footage of their backstory. Sure, let's get a pregnant Rita 5 inch figure. That would look...awkward as shit on a display. Or have an episode where the Zeo rangers are just hanging out before karate tournament at the beginning of the Turbo movie. Or a young Ninjor fig (I would actually buy that, so that is a legit idea) and why he chose dinos for the original power coins (or were they since there were five previous teams?).

This show just isn't a smart business venture. Even with great fan support, I think Saban Brands would not even consider doing it. Would Chip Lynn run this? Cause he is busy on the regular season, but you know who is available and a family friend of Haim Saban's? Jonathan Tzachor; consider that for a sec. All of your ideas as handled by JT. Let it sink in.

So if Nick wouldn't air it, the toy line wouldn't make enough money to sustain the show, JT could end up as the show runner, and the big wigs at Saban wouldn't see the profit in producing the show, I would think that it wouldn't happen. The best bet (read that as cheapest option for Saban Brands) is to address this stuff in the comic books as MrHerofan stated.

Legendary Zeo Megazord
 

I have just learned that not including the center piece of the Red Zeo Racer Zord that you can take one half of the zord to form a new arm and the other half for the other arm before putting the center piece into the chest of the Legendary Megazord, which means that you can form a slightly better version of the Legendary Zeo Megazord instead of placing all of the parts onto the same Zord Ports that you would normally use for all five pieces of the SPD Zord. Has anyone else realised that?

We could have a dark season in the future ?

The odds of there being a dark season in PR are about as likely as Kamen Rider getting another crossover here in America.

Those times ended with Jetman, I believe.

Have you ever seen how up-in-arms parents get about kids' shows? That could lead to a change of time slot or an early end for the season.

We got Jetman?
