Other collections from the Dragon Ball universe.

When we talk about the "other works" that are official but non-canon in the Dragon Ball universe, we refer to any manga or book that is based on Akira Toriyama's original story but is neither the original Dragon Ball nor Super (which are the only ones where the script is by the author of the work).

Within these collections, we can find the famous compendiums, the "Heroes" manga, and even one-shots like the story of Yamcha.

The manga collections, one-shots, or books you will find in these collections, as we mentioned, are all official but not canon. To understand this, let's look at the following:

• Official Product: A product licensed by the rights holders for use.
• Canon Product: A product that follows the true story defined by its author or intellectual owner.

With this in mind, we need to be clear that, as far as the Dragon Ball franchise is concerned, the only canon (on paper) are the original DB manga and the DB Super manga. And official are all those stories in manga or book form, and other paper products, that carry the DB seal and are approved by Shueisha (the holders of the Dragon Ball paper license).

Among these other works dedicated to Dragon Ball, you can find different alternatives:

• Books: You will find books with detailed information about the work, such as interviews, character profiles, and also novels that are akin to a movie, like the "DB Super Broly" novel.
• Mangas: Of course, there are mangas based on this universe, such as the "Heroes" manga, which deals with an alternate reality, or the "SD" manga, which tells the original adventures with a much more humorous tone.
• One Shots: Single-issue mangas that tell a self-contained story based in this universe. An example of this is the manga "Jaco the Galactic Patrolman."
