Factual error: Zordon tells the Rangers that their Zords are based on Dinosaurs. 2 of the Zords are the Mastadon and Sabre-toothed tiger - these are not dinosaurs, merely pre-evolutionary creatures.

Continuity: When Pudgy Pig is standing outside of the food packaging plant, a human hand can be seen sticking out of Pudgy Pigs left wrist.

Continuity: Up until Green No More in Series 2 (where the Green Ranger powers are destroyed), the Green Rangers overshield constantly changes between solid-looking metal to flimsy-looking cotton.

Other: In the scene where Tommy is proving himself to Goldar on the beach against the putties, Tommy stares down the last remaining putty and makes a charge towards him. In the wide shot of Tommy charging towards the putty, one of the "dead" putties on the ground lifts his head off the ground slightly, almost as if he is watching the action unfold.

Plot hole: How were the Rangers (minus Jason) able to form the Megazord if Jason wasn't there to summon the Tyrannosaurus?

Continuity: Rita mocks the Rangers from the cliff. Between shots, Rita's scepter changes, with the circular emblem changing from thin and circular; to thick and oval.

Revealing: When Goldar flips Jason into the wall, Jason's foot moves the wall back almost completely out of shot.

Audio problem: The Megazord throws the Dragonzord into a nearby mountain. As the Dragonzord tries to get back onto its feet, Jason, from the cockpit of the Megazord, tells Tommy to "give it up". An actor who then sounds absolutely nothing like Tommy replies "No way."

Continuity: When Tommy gives Jason his Power Coin, Jason receives the Overshield and Dragondagger. The positions of Jason's arms change between frames when he receives them.

Plot hole: When Billy is under Rita's spell, he goes to the Command Centre, and calls on the Dragondagger from Zordon. When Tommy gave up his power coin in the Green Candle, he was shown to have given the Dragondagger to Jason, not to Zordon.

Revealing: Certain monsters in Zord battles were designed for the first series. This is so Saban could use Japanese footage of ground fights, to save on shooting their own (As the costumes from series 1 carried over into series 2). Sometimes, you can see the Megazord, and Dragonzord, getting attacked (you may need to pause it). It should be the Thunderzord, or Tigerzord.

Factual error: Whenever we are shown Lord Zedd's palace on the Moon, we can see dark storm clouds overhead...which, of course, is impossible on the Moon.

Continuity: Billy takes Kim's mirror, and it has an blue backing. After Billy morphs, the mirror now has white markings on the backing.

Continuity: During the Green Candle, in series 1, we are told that the only reason Tommy's Green Ranger powers could be drained is because he touched a special wax. However, Kim, Billy, Zack, and Trini did not touch the special wax, therefore the candles shouldn't have stolen their powers. When they were captured, they were transported straight to a prison cell as Goldar lit the candles, therefore the Rangers couldn't have touched the candles when captured.

Continuity: When Bulk and Skull are waiting out the appearance of the Rangers, Bulk's kneepads are just below his knees. When he goes to grab Skull (after the explosion), they are around his ankles. When they arrive at the explosion scene, they are on his knees.

Continuity: This can only be seen for a few frames, so slow motion may be needed. Tommy reveals himself as the White Ranger by unclipping his helmet; however, his ponytail is already visible. Tommy's hair should have been inside his suit/helmet if he had just unclipped it. From behind shots, it is tucked in.

Revealing: The giant tin opener Bulk and Skull use to try and open Rita's dumpster is not metal at all - you can see the handle flopping over. It is more similar to Styrofoam.

Continuity: The Tigerzord has various orbs behind the White Ranger, that give the Tigerzord various abilities. The only one we ever see used is the one for a Fireball. For the rest of the series, this orb disappears and reappears, whether the Fireball has been used or not.

Continuity: When Tommy is ambushed by the putties, he kicks one which explodes despite the fact that the Z on the puttie's chest never glowed white like they always have in previous episodes.

Deliberate "mistake": A few deliberate mistakes here. It was around this time that 3 of the actors on the show (Austin St. John, Walter Jones, and Thuy Trang; who played Jason, Zack, and Trini) walked out over pay issues. So, to work around this until replacement rangers could be found, Saban used old footage of the 3 that walked out. The mistakes are as follows: 1) Tommy is shown to be wearing green. The Rangers wore clothes that matched the colour of their powers - Tommy was now the White Ranger (and should be wearing White clothing), as the Green Ranger powers had been destroyed. 2) Zack's hair changed from dreads, to his flat cut. This had an instant effect on Kimberley and Tommy's hair (again, due to the old footage), which had gotten noticeably longer as the series progressed. 3) Jason, Zack, and Trini's voices were different when they were morphed - obviously, they were voice sound-a-likes.
