Different counts

  • Series books/comics: 23 in one complete collection listing.
  • Other Avatar-related books: some lists include novels, art books, databooks, and comics, so the total can be higher depending on what you count.
  • Comic arcs: a separate list of Avatar comics exists and includes multiple story arcs such as The Promise , The Search , The Rift , Smoke and Shadow , and others.

Quick note
