Avatar: The Last Airbender - The Lost Adventures will collect 170 pages of previously printed comics and 70 pages of never-before-seen material, reports Comics Alliance.
The stories are in-continuity and fit between the episodes of the three original television series.
The collection will be followed in 2012 by a series of manga-sized digest books which will continue the characters' stories from the conclusion of the show.
Dark Horse's Avatar stories will debut in a flip book with Star Wars: The Clone Wars on Free Comic Book Day in May.
