As surprising as it might seem in a post-Marvel world where every major blockbuster has to include a post-credits scene, "Avatar: The Way of Water" decided to skip the addition. While it's not entirely known why the film doesn't contain one, it's likely that it wouldn't have fit James Cameron's vision. As the sequels were being written during the early 2010s (via Deadline) before the post-credit scene craze took over every major release, the idea of throwing one in may have just not crossed anyone's mind during the film's making. The ending of "The Way of Water" sees Jake Sully and his family victorious in their battle against Quaritch. They stay with the Metkayina clan as they prepare for even greater battles ahead, which is hinted at throughout the movie, thus eliminating the need for a post-credits scene.
But "Avatar" post-credits do exist. When the first film was re-released in September 2022, the movie was given a post-credit scene for the first time. The scene in question gave fans an extended preview of "The Way of Water" (via ComicBook), only creating more anticipation for the upcoming film. Fans responded positively to the addition, with Twitter user @enteumestay exclaiming, "Just saw the Re-release of #Avatar and I'm glad I stayed coz I saw some scenes from #AVATARTheWayOfWater and it was soooo goood. I can't wait for December!" It may be disappointing that "The Way of Water" doesn't include a tease for "Avatar 3" after its credits, but that doesn't mean fans aren't hotly anticipating the next one.
