Other mistake: At the end of the intro, before the logo appears you can see Mojo Jojo's brain. His brain is green and it should be pink.
Other mistake: During the first dozen or so episodes, during the opening credits, Onizuka is shown spray-painting a picture of a woman on a wall, with the words "Love" and "Piece" written next to her. Obviously, "piece" is a mistranslation, and the wrong spelling. The correct text should read "Love" and "PEACE."
The Planet of Dr. Moreau - S1-E4
Other mistake: When the mountain starts to collapse, the Silver Surfer and the enslaved trolls begin falling to the ground below at a rate comparable to what the falling rate on Earth would be. The Surfer is able to catch himself on a ledge and absorb his restraining collar into himself, granting him control over his powers, which he uses to prevent the trolls from falling to their deaths. With the amount of time the Surfer spent struggling to overcome his restraining collar, the trolls would have already fallen to the ground.
Other mistake: When the monk returns the water bottle to Siro and Taja, not long after talking to them (not realising the water bottle belongs to Kung Lao), how did Siro and Taja get so far ahead of the monk in that short amount of time? (00:05:35 - 00:06:35)
Other mistake: They keep saying the taxi cab is 20 years old, but that cab is brand-new in the episode.
