Master Vile and the Metallic Armor (2) - S3-E29
Corrected entry: When Master Vile's monster drains power from Ninjor, we can see that some of Ninjor's appearance transfers over the monster. When the monster does this to the Rangers however, the appearance drain matches of the Aquitain Rangers (Who had not yet come into the series). This is because Saban had carried over the costumes from the previous series, so that all 6 Rangers could remain (Due to their only being 5 Aquitain Rangers).
Corrected entry: Throughout season 1 - 3 the rangers call upon the zords. We then see them all get into their zords. However, when they go for the megazord, we see the saber tooth tiger, Triceratops, Mastodon and T-Rex all combine and form "tank mode." We then see inside the cockpit of the megazord at this stage and all 5 rangers are present. They then switch to battle mode whereby the megazord stands up and the Pterodactyl comes in and joins together creating the shield on the megazord's chest. However, up until the pterodactyl joins the others, Kimberly shouldn't be in the main cockpit as we've seen her in her zord.
Correction: The Pterodactyl zord sits on the shoulder section of the T-Rex, while in tank mode.
Correction: It's possible, and quite likely, that her Zord has some sort of autopilot. At the very least, that maneuver (which is identical every time) could easily be computerized.
Corrected entry: Throughout series 1, there is a World Map on the classroom wall. It still lists the Soviet Union. The show was made in 1993, a full 2 years after the Soviet Union breakup.
Correction: An out-of-date map on the wall of a classroom? Hardly unusual.
Correction: Actually this was because all of the Zord battle footage (and therefore the footage of Globber fighting them), was taken from the Sentai series KakuRanger. The KakuRanger were the Alien Rangers of Power Rangers. They were the ones fighting Globber when the footage was made.
