Character mistake: Troy calls for the "Twistornado" but his card reads "Windrive"; the cards have always read exactly what the rangers called for.
Power Rangers Megaforce (2013)
1 character mistake in Harmony and Dischord
Starring: Andrew M. Gray, Christina Masterson, Ciara Hanna, John Mark Loudermilk
Other mistake: If you look closely at the army of Rangers in the opening credits, you can see four versions of Tommy Oliver: Green Ranger, White Ranger, Zeo Ranger Red, Black Dino Ranger. Even though he had a single clone made, he can't be four variations at the same time.
Narrator: Our world was once a safe and happy place until evil aliens arrived with one plan: to destroy Earth. Gosei, Earth's ancient guardian, awoke and called on a new team of teenagers to fight off this new threat. They are the Power Rangers Megaforce.
Mega Mission - S1-E1
Trivia: The last scene where the Rangers decide to make this their mission has the exact dialogue from the original pilot episode from 1993, right down to the pink ranger teasing she wasn't going to accept the position before saying "joking!"
Question: At what point did someone decide that the rangers should always be in the same civilian clothes? In the early years of the franchise the characters wore different outfits but now they are always dressed in the same things every episode.
