Xbox is discontinuing its long-running custom Avatar software, Xbox Avatar Editor, next year. Originally released three years into the Xbox 360’s life cycle, Avatars gave players a chance to create custom characters that looked just like them (or didn’t), and have those characters represent them in various only interactions. Despite repeated evolution and innovation of the Avatar customization process, Avatars have been carried over faithfully across three generations of Xbox consoles, with players still able to use their Xbox 360 customization options on the Xbox Series X/S.
