The NinjaNomicon, or simply Nomicon, is an 800-year old semi-sentient book from the Disney XD series Randy Cunningham: 9th Grade Ninja. Created by the Norisu Nine, it teaches the Norrisville Ninja wisdom, gives them powerful skills, and gives him info/gives him advice on how to deal with an enemy or a problem. It holds precognitive abilities, chooses who can and can't open it, only lets the true Ninja use its knowledge, holds a section on the Forbidden Knowledge of the Shadow Warrior. When Randy opens it, it connects and communicates with Randy mentally by putting him in a trance. According to Mac Antfee almost anything is possible inside it.

About the Nomicon

Randy Cunningham gets his hands on the book and, using what he learns from it, he helps keep the world safe from the forces of evil. Whenever Randy or any Ninja is in need of help or information about something, he can just ask the Nomicon. To answer his question, the Nomicon communicates mentally, leaving his or their physical body in a trance-like state. There is a running gag that whenever Randy goes into the Nomicon, Randy will often fall to the ground and sometimes have the Nomicon hit his head.

The Nomicon may have a mind of its own. In "The Tale of the Golden Doctor's Note", when Randy "dissed" it, the book glowed and gave off a roaring sound. In "Viva El Nomicon", when Randy was acting too confident in himself, the Nomicon locked up until he learned the lesson. It also spoke to Mac Antfee as shown in a flashback to Randy in "Ninja Camp".

The Nomicon may also have the power of precognition. This is proven that the book seems to know in advance what kind of situation Randy is about to get into, and gives lessons which act as either warning and/or advice for that exact situation. For example, in "Stanks Like Teen Spirit", it warned Randy beforehand that his enemies were up to something, but Randy didn't take it to heart, and because of it, he woke up to find a lot of stanked monsters.

The Nomicon can also only be opened by the one who is chosen to be the Ninja. This was demonstrated in "Raiders of the Lost Nomicon", when Viceroy, McFist and even the Sorcerer attempted to open it with no success, although it's implied the Sorcerer's magic of red stank would have succeeded if Randy hadn't interfered. Howard failed to open it as well in "The Ninja Identity". However, it seems the Nomicon can choose who can and cannot open it. Bucky Hensletter opened it in "Raiders of the Lost Nomicon" since he claimed it had "non-school board approved ideas in it," and it also refused to open for Randy in "Viva El Nomicon".

In "Shloomp! There It Is!", once Howard notices that something's up with Randy (who is actually NomiRandy), he tries to get into the Nomicon. He can't until he throws it at a garbage box and it flies back at him, open, so he can get in, freeing the real Randy. Randy then goes to defeat NomiRandy in Howard's body, before returning things to normal.

While it often leads Randy to the pages where it feels Randy needs to go, the NinjaNomicon doesn't seem to have the ability to deny him when Randy is particularly determined. He has on several occasions forced his way into the House of Forbidden Knowledge and also has taken the ultimate lesson too early.

It's revealed in "The Ninja Supremacy", upon the Ninja's time ending, they take the Ultimate Lesson, whereupon their minds are wiped and the Nomicon absorbs all their experiences so it can be passed on to the next Ninja.


The Disney Wiki has a collection of images and media related to NinjaNomicon.


  • The NinjaNomicon's name may be inspired by the Necronomicon.
  • In "Enter the Nomicon", it's revealed that in the Nomicon, anything is possible.
  • Randy often uses the jacket of a math textbook to conceal the Nomicon.
  • The Nomicon will tend to face palm itself whenever Randy misunderstands it's lessons.
  • Hidden in both "Last Stall on the Left" and "Viva El Nomicon," "A wild beast may wound your body, but an evil friend will wound your mind."
    • In the same two episodes, information about a Zom-Bully can be found.
  • The Nomicon both inside and out is decorated with the Greek Key motif which has several meanings, such as "Infinity" and "Eternal flow of things". More modern meanings symbolize it as "Eternity" and "Unity".
  • The Nomicon may not be all-knowing, as the lesson "Friendship is a weight the Ninja cannot carry" proves to be wrong, inasmuch as Howard has surprisingly proven to be one of Randy's greatest assets from "30 Seconds to Math".
    • However the Nomicon might be talking about how Howard tends to get them into situations and blaming it on Randy when it it actually Howard’s fault.
  • The word "Ultimate" is comes from the Latin word, "Ultimum" which means, "the last."
    • It's shown that the Ultimate lesson isn't just used primarily for the Ninja but can be used for other reasons, such as mind wiping Debbie Kang, making her forget Randy wasn’t The Ninja from "Debbie Meddle".
  • According to Scott Thomas, the Nomicon has nine chapters, like the Norisu Nine from the past.
