* Continuing the series: Simply continue watching the remaining episodes of "Fullmetal Alchemist: Brotherhood."
* Watching the original series: If you're interested in seeing how the story was initially told, you can watch the original "Fullmetal Alchemist" series. It has a different ending and is a different story.
* Exploring similar anime: There are many other great anime series with similar themes, like "Attack on Titan," "Code Geass," "Hunter x Hunter," or "Cowboy Bebop."
