A Remedy To Cure All Ills - S1-E6
Character mistake: King Uther calls the Lady Morgana, Morgause. (00:11:50)
Character mistake: Despite being a Greek mythology buff Maxie Zeus says "Vulcan" when he meant "Hephaestus" the Greek god of fire and the forge when he first spoke with Batman.
Character mistake: Ryan tells Jack that Darius turned into a werewolf right in front of his and Micki's eyes. Ryan and Micki never witnessed Darius' transformation into a werewolf at all.
Character mistake: Zordon begins to explain to the Rangers about their powers and then their Zords. At one point, he says "You need only to turn to the power of your Dino Zords." However, the subtitles get it wrong and spell it as if he's saying "Dinosaurs" instead of Dino Zords which is what he says. (00:10:38)
Character mistake: Dr. Kagan, who's a scientist and should definitely know better, points to Earth's solar system on the chart and calls it "our galaxy." This is roughly the equivalent of mistaking a dot this size [.] for the entirety of North America. (00:23:30)
Character mistake: When Harlan Edwards collapses and Dr. Arcane tells them to clear his airway, one of the other doctors addresses her as "Dr. Cane."
Character mistake: At the end of the scene in the grocery store when Rachel collapses and people run to her aid, the camera pans out to reveal a sign that prominently reveals a sale on "Pop Tards" or possibly "Pop Taros."
Character mistake: Throughout the whole series Jin and Sun refer to each other as "yobo." The subtitles continually translate "yobo" as either "Jin" or "Sun" which is incorrect. "Yobo" is Korea's version of "dear" or "sweetheart."
Character mistake: When Rarity sees her cat stuck in the tree, Rainbow Dash is sitting next to the cat, but when you see her, her cutie mark is not there. (00:17:15)
Smoking Gun - S1-E2
Character mistake: When the bad guys put the generator in front of the air vent, Nigel looks at the white smoke and pointing at it says "Carbon monoxide." Carbon monoxide is colorless, white smoke is mostly condensed vapor. (00:35:20)
Champion vs. Creator, Part II - S1-E27
Character mistake: Pegasus says his toon world cannot be penetrated, but that is not true since it's a magic card, so any card that destroys magic cards can destroy it. Furthermore, monster special effects can also destroy it.
The Blood of a Jeannie - S5-E7
Character mistake: Jeannie tells Tony that she can't blink, then immediately blinks.
Character mistake: Shaun says that the underground facility is "built like a bunker", but the single missile they dodged just created a huge hole a moment earlier. (00:11:40)
Character mistake: The title card says "Plummers Academy" instead of "Plumbers Academy."
Character mistake: The Sliders are constantly trying to interact with a new world despite not knowing anything about it. This action often leads to misunderstandings, arrests, or threat of death. Sometimes there's even posted signs that they don't bother reading until it's pointed out by someone they've upset or annoyed. Yet they continue this action. They played a death lottery without asking question, order beer when it's not available to them, or try to pay without local currency.
Character mistake: Throughout the series, General Ross refers to Gabe Jones as Gabriel. Someone of Ross' military credentials would not address another government agent by their first name. He would call him Agent Jones or simply Jones.
Spider Wars, Chapter 2: Farewell Spider-Man - S5-E13
Character mistake: When Stan Lee is asking Spider-Man what he plans to do after saving all of reality, he responds by saying to find the real Mary Jane. Moments later in the final scene, Madame Web tells Spider-Man that she is taking him to find the real Mary Jane, which elicits an incredulous response from Spider-Man, as if he didn't know that was already the plan.
Character mistake: Nathan suggests to Dwight and Audrey that maybe he should shut down the meeting of troubled people. As chief, he should know he has no authority to stop citizens from assembling.
Fenikkusu! Jigoku o mita senshi - S1-E6
Character mistake: When Jabu gets maimed by the Nebula Chain attacking from above, the commentator says "One point for Andromeda Shun." Points? There never were points during the previous fights. (00:11:05)
Character mistake: After Anakin says to use the walkers (AT-TEs) as boarding vessels, Rex calls the first one an AT-AT (a vehicle that does not even exist at this point in-universe) while ordering a battalion of clones into it. (00:04:10)
