- Acting for Two:
- Grant McFarland as Sensei and Lothor and Danny Sing as their past selves.
- Jason Chan as Cam and Cyber-Cam.
- Actor Allusion: In episode 12 of the Australian series Wonderland, the gang attends a wedding. At the reception Carlos shows off some moves on the cleared dance floor that are quite... gymnastic for such an event—an allusion to actor Glenn McMillan's time as the Yellow Wind Ranger on Power Rangers Ninja Storm.
- Author Existence Failure: Shane's actor Pua Magasiva unexpectedly died on May 11, 2019, when he was just 38 years old. While his cause of death has not been publicly revealed, it's speculated that he may have taken his own life; his brother Robbie revealed in an interview that he was struggling mentally and shot down his attempts at helping him shortly before he died. Much like Trini and Udonna, it's unknown if this also marks the death of Shane in-universe as well, but it means we most likely will never see him on-screen again.
- Shortly beforehand, Grant McFarland (Lothor/Sensei Watanabe) died on November 20, 2018 at the age of 71 from an undisclosed cause.
- Dawson Casting: Averted with Sally Martin (Tori) and Glenn McMillan (Dustin), who were in their teens at the time of filming. Played straight with everyone else in the central cast, with Pua Magasiva (Shane) and Adam Tuominen (Hunter) being in their early 20s, Jorgito Vargas Jr. (Blake) being in his mid-20s, and Jason Chan (Cam) being in his early 30s (though it's implied Cam is older than the others, it's highly unlikely he's that much older).
- Fake Nationality:
- New Zealander Grant McFarland and Malaysian Jason Chan as the Japanese Kanoi and Cameron Watanabe.
- This season also started the trend of hiring Australians and New Zealanders to play Americans.
- Jossed: Although Word of God below said otherwise, for a while, some fans believed Tori's Arbitrary Skepticism in the premiere meant that Ninja Storm was a continuity reboot. However, Once A Ranger features Tori alongside Adam, which places this in canon.
- Name's the Same: Shane shares the same first and last name of the guitarist for 3 Inches of Blood, except the Ranger's name has an E at the end.
- Crimson Ranger Hunter Bradley also shares the same name with one of the members of the Blitz Team. *
- No Export for You: In South Korea, due to the ninja theme. They skipped it for Bakuryuu Sentai Abaranger.
- Playing with Character Type: Cam is one of the only green rangers in the entire franchise who isn't a comic relief character, unless you count his snark.
- And by one of the only we mean besides: Tommy, Adam, Carlos, Trip, Xander, Mike, and Riley.
- Real-Life Relative: Shane's older brother is played by Pua Magasiva's brother, Robbie.
- Unfinished Episode: A crossover with Wild Force was planned as stated in an interview by producer Jackie Marchand, but due to production relocating to New Zealand and that it would be too expensive to bring in the cast, it was scrapped.
- What Could Have Been:
- Very early materials suggested that the rivalry between the Wind and Thunder Rangers was supposed to play out a lot longer than it did (and possibly be the central conflict of the series, rather than a traditional villain), with kids even being encouraged to pick sides for themselves.
- The Tori character may well have become a carbon copy of her Hurricanger counterpart (aspiring Idol Singer Nanami) had Emma Lahana, who auditioned for this role before becoming Kira in the following season, gotten the part instead of Sally Martin.
- According to Doug Sloan, he wanted to avert The Smurfette Principle by doing a Gender Flip of one of the Rangers (most likely not Red or Yellow), but Disney vetoed it. Had this happened, then we might've seen the first female non-Yellow Ranger with a male Sentai counterpart.
- As noted above in "Unfinished Episode", a Wild Force crossover. Interestingly, unlike with Reinforcements from the Future, they would've been able to use stock footage, as there was a crossover between the two sentai teams, so presumably the costs from moving the cast of Wild Force to New Zealand for filming wouldn't have been offset by what they could've saved using stock footage.
- Whether or not Amit Bhaumik's (who was the head writer for Wild Force, and, had Disney not acquired the franchise and moved production to New Zealand, would have likely stayed on for the following season) ambitious plans for Hexagon could have even gotten off the ground, the very concept would have resulted in a VERY different season.
- Word of God: Doug Sloan has said more than once that Tori's Arbitrary Skepticism in the premiere was meant to be taken as just that and never as an indication of a continuity reboot.
