TJ, Cassie, Ashley, and Carlos are the final Power Rangers in the show's history (thus far) to gain a new power source after losing their previous ones.
This was intended to be the final series of Power Rangers, due to disappointing ratings from Power Rangers: Turbo (1997). The success of the series insured the survival of the franchise.
This is the first season of Power Rangers where a Ranger is related to the villain.
According to Christopher Khayman Lee, the cartoony, sci-fi skunk stripes in his hair were not his idea. At first, they told him he was going to wear a wig; but then, when he came to L.A. the crew were basically like, "Surprise! We're going to bleach your hair now!" It was painful to say the least; in fact, it took at least 8 hours to get it just right, and with his head feeling like it was on fire on top of that. Even worse, his hair grew so fast which meant his roots began to show in his streaks... meaning that they had to touch-up those roots with the bleach each time. In spite of it, he still enjoyed his time on the show regardless.
On Christopher Khayman Lee's first day on set, he was pulled aside by Jonathan Tzachor and was told to act like an asshole to his castmates and to avoid them off-screen so that Lee could get into full character as Andros, much to Lee's chagrin. So when you see Andros eventually warming up to the rest of the Space Rangers, you'll know why.
