Continuity: When the Villains send their cronies (for example, Putties, Tengu Warriors, Cogs, Piranhatrons, etc.), their numbers constantly change from when they arrive, to when they leave.

Continuity: When the Rangers morph, the clothes they are wearing don't match what they have been wearing that episode - this also applies to hair.

Revealing: In SPD Episode "Sam Part 1" (13-7), when the Ranger first yells "SPD emergency," a piece of Jack's Morpher breaks off.

Revealing: The Putties, which Zedd and Rita use as cannon fodder for the Rangers, are made out of clay. When they are hit, chalk appears, to signal that they are being "worn down". When played in slow motion, we see that the chalk is on the Ranger's feet, before they hit the Putties. This is particularly true in closeups.

Continuity: In the 12 series (Power Rangers Dino Thunder), in the episode "White Thunder Part 3", Conner (as the Red Ranger) throws his blaster to the ground whilst fighting the White Ranger, Ethan. In the wide shot, the blaster disappears.

Other: Episode 13-12: "Shadow (2)." When Cruger is challenged to defeat 100 robots, a red countdown meter appears on the screen, ticking down each time Cruger dispatches an opponent. When the counter is at 21, Cruger slices his sword at a robot, which then goes down. But the counter stays at 21 and only goes to 22 when he slices at the next robot. Every robot in the sequence goes down after a single hit from Cruger's sword. Submitted by DavidK93

Revealing: Until the end of the 5th series, we can see part of the Zord costumes move about as the character in them walks about - sometimes they even look like they are going to fall off. This is particularly true in the 2nd series.

Factual error: This happens until the end of series 3. Lord Zedd and Rita send down monsters to Angel Grove, in California. Yet when they cast their projectiles down to Earth (for example, with Zedd, a lightning bolt) they are seldom ever aimed even in the American continent.

Factual error: This happens mostly during the early series. Whenever the Rangers throw a flying side kick (the jumping one that they seem to be rather fond of), they do it all wrong. They throw the kick leg out from the start, while the kick is actually thrown with the leg chambered until the moment before impact. Throwing it the way that the Rangers do will jam your leg.

Visible crew/equipment: This happens mostly in the first 4 series - crew, lights, and equipment can be seen reflected in the Rangers helmets and visors.

Other: In one episode of Power Rangers Dino Thunder, Ethan is seen playing a game on a computer, Connor comes in and Ethan looks away from the computer to talk to him. The game Ethan was playing is still going, but Ethan has stopped playing, obviously a demo.
