14. Avatar: The Last Airbender
As another LEGO collaboration that was way too limited, the Avatar: The Last Airbender series only got the chance to release an Air Temple set and Fire Nation Ship set. Of the two, the 722-piece Fire Nation Ship edition had the best accessories, including a catapult for launching LEGO pieces through the air and five key characters to make the set complete. It was also the only set released that paired Prince Zuko, Katara and Aang in one pack. We could have at least had a set that allowed fans to piece together the map of four nations.
