I think it's best to start from the comic that sets the foundation of the story. Then follow the ones that build on it. This way, you'll have a clear and enjoyable reading experience without getting confused about the plot progression.
To be honest, I don't have the latest update on whether Atla comics are still being produced. But you can follow some comic-related forums or social media groups dedicated to Atla to stay in the loop.
One great 'atla space fanfic' could be 'Avatar in the Stars'. It takes the characters from Avatar: The Last Airbender and puts them in a space - faring adventure. The way it blends the bending abilities with space - themed challenges is really interesting.
There's 'Guns and Bending' which is also a popular 'atla gun oc fanfic'. It explores how the presence of a character with gun - related abilities affects the power dynamics in the ATLA world. The story has some exciting battles and character interactions.
Some ATLA - focused forums might also be a place to find the best fanfic. These forums often have sections where fans discuss and share their own writing. Additionally, if you follow ATLA fanfic writers on social media platforms like Twitter, they might announce when they've written a new and great piece that could be considered among the best.
You can buy 'atla graphic novels' at many major bookstores like Barnes & Noble. They usually have a section dedicated to graphic novels where you can find them. Also, online retailers such as Amazon are a great place to look for them. You can often find both new and used copies there.
