Adaptation Dye-Job: The Pink Ranger's Triceratops zord was initially indigo in the toyline, despite being pink in the show. But due to fan outrage it was changed back to Pink. (Though it's entirely possible that the initial indigo color was nothing more than a factory error and it was always meant to still be pink)
Fan Nickname: The opposite of last year's (Super) Megafail is Dino Hope.
On the subject of Ivan, quite a few predicted that he would be a medieval knight since in the source material, his Sentai counterpart was a samurai.
Kendall becoming the Purple Ranger after Albert's tenure. Kyoryuger, the casting sides that Saban Brands released, or the color of the glasses were dead giveaways.
Quite a few predicted Tyler's dad, James becoming the Aqua Ranger. The big giveaway was the scene where James gets crushed by the boulders in the flashback scene of A Date with Danger, since when he got crushed, a bright aqua light emerges from the rocks that crushed him, indicating he bonds himself with the aqua energem.
A lot of theories surrounding season 2 suggested that Sledge wasn't killed in the crash, and that he would be the Bigger Bad of season 2. Sledge's survival was confirmed via the synopsis for the episode Worgworld.
Kendall shares her first name with Danny's love interest in two episodes of Power Rangers Wild Force. Her name is very similar to Kendrix Morgan, the first Lost Galaxy Pink Ranger who was also a Hot Scientist. An interview with Judd Lynn, however, says that the two are unrelated and that he didn't realize the similarity until he was told.
Going even further than that, Yoshi met with some of the Sentai producers, who were so impressed that the producers for Hikonin Sentai Akibaranger and Kaizoku Sentai Gokaigerdubbed him the real-life version of their shows' respective Promoted Fanboys, Nobuo Akagi (Akiba Red) and Gai Ikari (Gokai Silver).
The subtle KyoryugerShout-Out in episode 3 (Chase singing a song with the same tune as the opening theme "Vamola! Kyoryuger" and Koda whistling the song toward the end) was apparently something Yoshi and James Davies (Chase's actor) planned out together and got put into the show.
Promoted Fanboy: Aside from Yoshi above, there's Michael Taber (Green Ranger) — he's a longtime fan of Power Rangers and even went as Magna Defender for Halloween as a child!
Short Run in Peru: Brazil is getting the Supercharge episodes - and the spoilers contained therein - three weeks ahead of broadcast in the USA. In Australia, the episodes air one week earlier.
Teasing Creator: Before the Aqua Ranger's official debut, scattered throughout the season were various minor characters with cyan motifsnote Tyler's missing dad's shirt (he turns out to be the one), The Dino Café waitress serving the Rangers as they discuss the Ankylo Zord, Julian the photographer with his inner T-shirt, the snatch thief in New Zealand with his bike and Heckyl with his Skunk Stripe and innerwear.
Prop Recycling: Several of the monsters in Sledge´s prison apppeared somewhere in the past seasons. One of the most obvious is Necrolai/Vancuria (difference unclear) in Wishing For a Hero as she is visible all the while Heckyl clashes with Sledge.
The retreating monster Heckyl kills in When Evil Stirs has the head of Dumbbell Bot from RPM
Early casting calls show that Riley was originally named Ryan, Tyler was originally called Lucas, and that Kendall was going to be called Kiera. All three were changed due to beingpreviouslyused.
Casting information listed Riley's brother Matt as The Graphite (then called Gray) ranger. However, the official toy bios revealed that the ranger was actually Prince Phillip, who at that point had not yet been introduced on the show.
There are several firsts in this season for the franchise.
Unless we get an American exclusive Yellow Ranger, this will be the very first Power Ranger series without a Yellow Ranger.
Also the first series to have a Pink Ranger be black.
Camille Hyde, Shelby's actress, is another first: the first Ranger to be born after Mighty Morphin's series premiere in August 1993, being born the following November.
Michael Taber, Riley's actor, is even younger and the first ranger born in a year after the series' first.
Just missing out on becoming the first Ranger born after MMPR's premiere was Claire Blackwelder (Kendall), who was born two days before.
Also the first Indonesian ranger (Yoshi Sudarso).
The episode Sync or Swim marks the 800th episode of the entire Power Rangers franchise.
According to a ComicCon interview, Camille Hyde (Shelby) and Claire Blackwelder (Kendall) are from the same hometown, and even have some of the same friends. They didn't know it until they met on set and one of them happened to mention where they were from.
Dino Charge has the distinction of having the oldest-living rangers, both in terms of in-series age (Koda, at 100,000+ years old) and of the oldest actor to portray a Ranger (Arthur Ranford, who plays the first Purple Ranger, is 67 years old).
For a while, this even beat the sentai record. Shigeru Chiba, who played his counterpart, was only 59 at the time, and Tsutomu Sekine was 61 during ToQger. Sentai finally caught up when Takashi Sasano matched Arthur at 67 years old when he became an Eleventh Hour Ranger during the final arc of Ninninger.
Yoshi and Camille have said that Home Run Koda is their favorite episode.
