Continuity mistake: Piranatrons have always been small and weak - their appearance hadn't changed for 2 series and a film. Yet when Quadtrons and Piranatrons are fighting the Phantom Ranger, the Piranatrons are noticeably taller and larger than normal, when standing behind Divatox. Divatox has ALWAYS been bigger and taller than Piranatrons.
Suggested correction: That is an impossible detail to notice considering she has an army of them...and they squat most of the time. You can't definitively state that all of them have been shorter than her while standing and the ones in the movie are indeed different. You can't say that just because this one time when two are standing taller than her...that they ALL are small and weak.
