California Doubling: As with the previous seasons, the Power Chamber exterior is The House of the Book performance hall and library building at the American Jewish University, Brandeis-Bardin Campus in Simi Valley, California.
The Cast Show Off: Besides the obvious martial arts, Kat's ballet dancing and Tanya's singing.
Real Life Writes the Plot: Billy's abrupt departure, which used an aged-up The Other Darrin and stock footage, came about when David Yost walked off the set after he had had enough of the creators, producers, writers, and directors insulting and harassing him for being gay (as revealed in this interview).
Notably, It wasn't until Power Rangers (2017) before David Yost had ANYTHING to do with Power Rangers since, and one of the first things that happened was that Haim Saban publicly apologised for the terrible things from that time.
Unintentional Period Piece: The computer virus episode is filled with hilariously early-90s ideas of how computers and the Internet work.
Urban Legend of Zelda: "Scorpion Rain". Five one-minute shorts broadcast prior to Foxtel's screening of the final episodes of the season in Australia, created to better link the events of the finale to the feature film of Power Rangers Turbo. In actuality a hoax concocted by Big Name Fans Derik Smith, Joe Rovang, and Amit Bhaumik. Later subjected to Armed with Canon
Word of God: Bhaumik's "Forever Red" retroactively establishing that there was a final, unseen conflict between Rita and Zedd and the Rangers which led to a damaged Serpentera buried on the moon, and Zeo writer Jackie Marchand's "Once A Ranger" revealing Rita was pregnant with Thrax by the events of the season finale.
At different times, Bhaumik and Doug Sloan also went on record as saying that the ending to "A Season to Remember" is in-continuity.
