This takes place before the movie.In the movie, Kuzco was the emperor, in this one, he's training for it. It clears up the Aesop Amnesia. And, with selfish Kuzco, it makes a fair amount of sense for him to forget all the peasants.
Both levers are wrong...at first.Kronk rigged them that way for a laugh. While Yzma is too busy getting out of whatever trap he laid, he puts in a code on a secret keypad to make one lever right. She just never bothers to remember which lever was wrong last time. When Kronk first had the idea, sneaky Kuzco came across a piece of paper with his code.
The female llama herder in the early versions of the movie was retooled into Malina.Kuzco has no other Love Interests.
The Spaniards have already been visiting the Americas, and about to colonize.Explains why they also serve Spanish rice and Swedish meatballs. And why they refer to their own gods as myths. And why Malina tells Kuzco being Emperor doesn't make him better.
This takes place WAY after the movieThey're decendants of the movie ones. See above. There are also backpacks, elections, and robots.
Kuzco is putting on a mask for public appearances.Basically, as far as the entire kingdom knows, he still IS a spoiled brat. He's not ignoring the events and Aesop of the film, but instead keeping up appearances so he doesn't get swarmed for being the nice emperor-to-be. Can you imagine how many demands he'd be given once he took the throne if he was a nice guy on campus? He's being Genre Savvy, or something similar. The only problem is that he hasn't included Pacha and company on his plan.
If a new movie in The Emperor's New Groove series is ever made, this series (and Kronk's New Groove) will be declared Canon Discontinuity.Because John Lasseter and his team believe that Disney should do their stuff for the art rather than try to make a quick buck off of it.
The show takes place in the alternate universe Narrator Kuzco from the film is from.I mean it makes sense. Narrator!Kuzco was just as much an idiotic, selfish jerk as Kuzco was at the start of the film and about as much as he is is in the show, yet Narrator!Kuzco knew what was going to happen, at least until the point Kuzco was in the rain. Narrator!Kuzco must come from an alternate universe where Kuzco never learnt his lesson, which is here in this show.
