Factual error: Trust called Proxima B an "eyeball" planet, meaning according to him a planet that does not spin on its own axis and always has one side facing the sun. That is incorrect. If only one side faces the sun it means the rotation on its axis and its revolution around the sun are the same.Otherwise, the planet would seasonally have all of its surface facing the sun once every solar year.
Deliberate mistake: When the news program is discussing Gyrich's assassination attempt on Xavier from the series finale of the original animated series, he's shown to have his classic look of auburn hair and sunglasses. However, when this scene occurred, Gyrich had black hair and was not wearing sunglasses. This was done deliberately to match the character design of the original series prior to the final 6 episodes, when Saban took over and redesigned much of the show's look.
Other mistake: Juliette and two cohorts need to go from Level 22 down to Level 125. Using the normal circular stairs, it would take several hours if not days to get there. They enter a garbage chute and climb down using a vertical ladder on the side - a very clumsy and slow descent. Yet, they make it in what appears to be a very short time.
Factual error: Season 1, Episode 10: Lee is trying to get out of the underworld on his capsule with the rescued others. They all get in, and he closes the top hatch by turning the hatch wheel clockwise. Trying to take off, a wire becomes disconnected outside, and Lee has to go out again. He turns the hatch wheel clockwise, and this time it opens instead of closing. If it was clockwise for close, it should be counterclockwise to open.
