For the video games:
* The original "Avatar: The Legend of Aang" game (2006): This game is linear and doesn't allow backtracking to previous levels.
* "Avatar: The Last Airbender" (2010): This game is also mostly linear. There are a few instances where you can go back to previous areas, but only for specific tasks or collectibles.
* "The Legend of Korra" (2014): This game has a similar setup to the 2010 game. While some areas may be revisitable, the overall story progression is linear.
For the animated series:
* The original "Avatar: The Legend of Aang" series (2005-2008): This series follows a linear storyline. While there are flashbacks and moments where characters revisit past locations, the main narrative progresses in a forward direction.
In short, you can't freely go back to any level in "Avatar: The Legend of Aang" (whether the video game or animated series) like you might in a traditional open-world game. However, there are instances where you might revisit certain locations for specific purposes within the game or series.
Do you have a specific level or instance in mind you'd like to know more about?
