The Invasion is known for having a high amount of KASUs
- "I do make mistakes from time to time, I'm afraid. I try not to, but on the other hand, it can be kind of a game for readers: find the KASU. The Katherine Applegate Screw Up."
- ―Katherine Applegate, November 1998
The Animorphs book series contained several continuity errors, or KASUs (Katherine Applegate Screws Ups) as the fans called it. While there are many discrepancies between the books and the TV show, these are not considered continuity errors because of the different medium.

This section requires expansion |
The section below does not list every continuity error/KASU and is in need of expansion. However, a full list of continuity errors/KASUs for each book are listed on the book's page under "Goofs/Inconsistencies".
- In Book #1: The Invasion, Jake is able to thought-speak to Tobias while not in morph. In later books, it is considered impossible to do in human form or human morph.
- In Book #2: The Visitor, Cassie says that Rachel, after acquiring her cat morph, has four morphs, which is more than any of the other Animorphs. But Jake, at this point, also has four morphs: dog, tiger, anole lizard, and peregrine falcon.
- In Book #3: The Encounter, Tobias states that Marco had previously acquired a bald eagle morph, and that he used it during the escape from the Yeerk Truck ship. Marco never acquired a bald eagle; his bird of prey morph is an osprey.
- In Book #8: The Alien, Ax says the Hork-Bajir are hardwired to war with each other every 62 years. This is not true in later books as it mentions Hork-Bajir never knew the concept of violence and fighting until the Yeerks and Andalites came (Although it may be that this was part of a propaganda campaign put out after the Andalites failed to save the Hork-Bajir to give the impression that they weren't that significant a loss).
- Ax also names the Yeerk rank Under-Visser, but it should be Sub-Visser.
- This happens in book 6, The Capture, said by Temrash 114.
- In Book #11: The Forgotten, Jake would check his watch to see what time it was, when he actually would have left behind his watch after morphing.
- In Book #15: The Escape, the Leeran homeworld is called "Leeran", but it was correctly called Leera in Book #18: The Decision
- In Book #46: The Deception, Ax, while morphing a human, says one heart disappears and the other becomes a human heart; Andalites have 3 hearts.
- In Book #52: The Sacrifice, Timmy is erroneously referred to as Tuan. The character was originally named Tuan; however, Applegate changed it to Timmy before #50 was published. Due to an editorial oversight, the name Tuan still appeared in #52.
