Deliberate "mistake": In fight scenes, the Yellow Ranger's stature matches that of a male (and not Trini). This is because in the Japanese version of the show, the Yellow Ranger was played by a man.

Revealing: When one of Rita's monsters tears a building apart, the buildings are completely hollow, and nothing more than 6 pieces of Styrofoam stuck together to look like a building.

Deliberate "mistake": When we see the Dragonzord, Tommy is sometimes standing on top of it. However, it is completely obvious that "Tommy" is nothing more than a small plastic figure.

Continuity: The clips on the side of the Rangers helmets constantly disappear and reappear.

Audio problem: Rita is dubbed over extremely poorly - her words don't match her mouth.

Plot hole: Up until about Green With Evil, we can see the Rangers fighting Super Putties, which didn't come into the Series until after Green With Evil.

Continuity: When in Tank mode and Megazord mode, the order in which the Rangers sit is: Billy, Trini, Jason, Kim, Zach. When switching between Tank mode and Megazord mode, Trini and Kim are switched - they are then back to their original seats once the Megazord has been formed.

Continuity: When the Dinozords are called, they emerge from their hiding places, and assemble in a line, before formed Megazord Tank mode. During this time, it is a completely rocky background. After the Sabre-toothed tiger assembles, we cut to the Triceratops - which is now assembling in a completely desert-like environment. It then switches back to the rocky environment.

Continuity: When the Megazord is in Tank mode, the Mastidon's head section is attached to the center of the Zord. But when the Zord begins to stand up and form the Megazord, the Mastidon head section is gone.

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.

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

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.

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.
