Super Ninja Steel was the last Power Rangers season to have its toys made by Bandai of America, and also the last season to be produced by Saban after they bought the franchise back. Starting with the season that succeeds it, Hasbro takes ownership of the Power Rangers franchise, producing both shows and toys alike (although Saban will still serve as creative consultant).
Jordi Webber is a singer in real-life and his character, Levi, gets to perform a few times.
Dawson Casting: As usual for the series, but fans gave special notice to Chris Reid as Victor. With lines like "he looks old enough to have a kid in high school, much less be in it" (a bit exaggerated of course, but still).
The Ninja Battle Morpher exists because Bandai asked Saban to change it from the sword used in Ninninger, knowing that the swords would sell well due to being the ranger's main weapons; including a separate morpher would increase toy sales.
Judd Lynn revealed at Power Morphicon 2018 that it was due to this trope that the comedy that's present in both this series and Dino Charge is here, and his team wanted a tone that was more akin to In Space.
Simon Bennett revealed on Rangerboard in 2022 that Saban passed down several mandates in regards to this series (although they had started taking a firmer hand during the latter half of Dino Supercharge, it really came to a head here); despite being ninjas the Rangers couldn't actually be seen doing anything ninja-like (other than sneaking around), there could be no over-arching plots (due to the belief that kids wouldn't retain the information), morphed fights had to be filled with characters making puns, there had to be at least two standalone Victor and Monty scenes per episode note with the only exception seeming to be the 25th anniversary episode and they had to use an increased amount of fart jokes (something the cast and crew hated doing).
Mostly played straight with Cosmo Royale, who appears to use the suit of Baron Nero from ToQGer (a villain, of course, not used in Ninninger, similar to Furio from Lost Galaxy), but with the head changed for one more cartoonishly monstrous.
The Super Ninja Steel Halloween episode had a group of seven monsters, three of which were not from Ninninger. One was Vancuria from Magiranger/Necrolai from Mystic Force (not the first time she's been recycled as she showed up in Dino Charge), another was Sanyo from Gekiranger/Snapper from Jungle Fury, and the last was Debo Kantokku from Kyoryuger, who was never used in Dino Charge.
Recycled Soundtrack: As part of the 25th Anniversary, Super Ninja Steel used background music from MMPR, including the Bulk & Skull theme for Victor & Monty.
Much like its Japanese parent show, most of the auxiliary Zords have poor articulation due to their transformation schemes (including Robo Rider, which has little excuse). As a result, the Robo Red, Dragon, and Rumble Tusk Zords got standard 5 inch figures made as part of the Morph Armor subline and can either sit in the command seat of the Megazord or stand in as better articulated stand-alone toys.
The Ninja Blaster toy was given a near-complete overhaul compared to the Ninninger version; the new toy has similarities in its basic design scheme but is very different in the detailsnote The American version has a more angular "cool" aesthetic with angry eyes, the mouth doesn't open, and it shoots Power Stars instead of having a tongue-shaped barrel.. Yet, the show itself and even the toy's packaging continues to use the Ninninger props, giving us a rare case where a Power Rangers toy is made that is blatantly not show-accurate.
The Ninja Star Blade is similarly... similar in a broad sense while being different in the finer details. The layout of the buttons on the blade are much closer together, the haft is much shorter, and it has an spring-loaded blade gimmick that gives it a narrower tip that extends when a button is pushed.
Comparatively, all of the Gold Ranger props are extremely similar between show and toy, with only minor differences between the Morpher and its toy counterpart. This is necessary due to the show using the Ninninger props for Power Stars while the toy uses the smaller foam ones common to the line.
Teasing Creator: Peter Sudarso had a lot of fun dropping little hints in the months before the season started: visiting a restaurant run by Kelson Henderson long before it was revealed that he would be returning to an on-screen role and posting a picture of himself with a third eye to slyly reference his character's last name being Tien. This has led some fans to comb through his pictures from that time frame and speculating which ones are also hints and which ones are simply for fun.
Unfinished Episode: An episode was written that would have Calvin and Hayley break up, Calvin would then start dating Sarah. Zoë Robins and Chrysti Ane talked to Chip Lynn about this, saying they didn't want to teach kids it was okay to steal your best friend’s significant other (not to mention that a white male dumping a black female for a white female can be interpreted as racist), and the idea was partially scrapped. Calvin and Hayley do break up at the end of the first half of the season finale but get back together in the second half.
Kelson Henderson returns to the franchise in his first Saban-era onscreen role as Brody's shapeshifter friend Mick. He was previously Boom in SPD, Phineas in Mystic Force, Norg in Operation Overdrive, Flit in Jungle Fury, and a handful of smaller roles (mostly voicing Monsters of the Week).
Josephine Davison who played Morgana in SPD and voiced Itassis in Mystic Force showed up in one episode as one of Sarah's teachers when she signs up for many clubs.
Daniel Sing, who played the past teenage version of Sensei Kanoi Watanabe and his twin brother Kiya, the present day Lothor from Ninja Storm, is the Mayor of Summer Cove, hence once more being part of a ninja-themed Ranger series.
she and Nico have met before on Season 10 of So You Think You Can Dance.
