LEGO Avatar: The Last Airbender

LEGO founded a theme based upon the popular Avatar: The Last Airbender television series. It is one of the shortest-running themes developed, as there were only two sets produced under its name; met with pressure from the competing SpongeBob SquarePants sets, the Avatar theme was ultimately forced to be discontinued.

Background
The two sets debuted as part of the first wave of Nickelodeon-themed LEGO sets following a partnership between the popular kids' network and the Danish toy company in late 2005. In this wave, Nickelodeon decided to include two of its most popular franchises: Avatar: The Last Airbender and SpongeBob SquarePants. In August 2006, the first five Nickelodeon LEGO sets hit retail shelves: Two based on Avatar and the other three on SpongeBob. Unfortunately, the Avatar product line never lasted beyond its first LEGO outing. Its SpongeBob counterpart, however, performed slightly better and remains an active LEGO theme to this day.

Perhaps Avatar: The Last Airbender ran too great a risk of becoming obsolete, as only three seasons were planned, and it was originally set to end the year after the first wave. Nevertheless, the sets produced are based only upon Book 1, thus recreating events solely from this time frame. Basically, the series had not yet encountered Toph, and Zuko was still bent on capturing Aang. There were only two new piece molds introduced in this theme, those for Momo and the wings of Aang's glider.

Aang is the only individual character from the series that appears in both sets. Sokka and Momo only appear in "3828 Air Temple" and Katara and Zuko only appear in "3829 Fire Nation Ship". Other mini-figures just portray generic Fire Nation soldiers. Important recurring characters that were already present in Book 1 and are not represented in any way in this theme are Appa the flying bison, and Iroh, Prince Zuko's uncle.
