Who that character will be remains a mystery, but one can speculate based on the story developments in the Creed movies and the narrative inspirations they draw from the parent Rocky franchise. Although an official release window for Creed 4 has not been announced yet, the film has been confirmed to be in development, making it hard not to wonder about the potential fates of its primary characters.
