* CharacterExaggeration: Kuzco's intelligence, big time. In the movie, he's sheltered and spoiled, but savvy enough to know that Yzma is trying to do his job behind his back and that she has a secret lab, in addition to being manipulative enough to play Pacha for a sap twice. In the series, he's often BookDumb or a straight-up IdiotHero.
* ClicheStorm: Firmly cemented by the almost exclusive reliance on gags and plots from the original movie.
* CryForTheDevil: Yzma has it pretty rough in some episodes.
** In "The Emperor's New School Spirit," she recounts how her high school classmates made fun of her, calling her "pigeon-legs." At her high school reunion, they [[spoiler: [[KickTheDog cover her with honey and bird feathers and continue to taunt her]]]]. With [[spoiler:Kuzco]]'s help, she [[spoiler: gets back at them by [[TheDogBitesBack turning them into pigeons]]]].
** In "Take My Advice," Yzma is fired at the very beginning and has to find a new job. [[spoiler:She makes a living as the "Dinosaur Lady."]]
** Vacation Time. Vacaton Time. So much fun.

** The theme song in general.
* NightmareFuel: The skeleton ant eater. On the bright side it came with a [[EarWorm really catchy song.]]
* SeasonalRot: The 2007-2008 second Season in comparison to the 2006 first season. Season 1 was very straightforward, with a standard 21 episodes that formed an almost equal mix of two-part episodes and episodes with two stories (9 and 12, respectably). Season 2 was 31 episodes long, and all but a handful of them were episodes containing stories---among the exceptions being the holiday specials and series finale---suggesting the writers couldn't come up with a story to last 22 minutes.
* SeinfeldIsUnfunny: The series reused so many jokes from the movie so many times that they became more annoying than funny.
** This is [[LampshadeHanging Lampshaded]] in one episode in which the whole "Roller Coaster Inside The Lab" joke was used so many times that it actually couldn't come up with something witty to say that hadn't been said before.
** Another LampshadeHanging comes when Yzma struggles to think of something new to turn Kuzco into and suggests a llama. Kronk asks, "You're kidding, right?"
** Yet another LampshadeHanging in that episode comes when Yzma tells Kronk to pull the lever, and Kronk does, causing something they've seen before to come down. He then keeps pulling the lever saying "Seen that, seen that" until they flip in.
* UglyCute: Baby Yzma.
* VisualEffectsOfAwesome: Lampshaded in Yzmopolis.
