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.
