Jonathan Majors' Creed 3 villain, Damian Anderson, is a combination of three Rocky characters, which makes his characterization all the more compelling. Unlike its predecessors, Creed III sets the stage for its overarching storyline by opening with a flashback. Set in 2002 Los Angeles, the flashback introduces a young Adonis Creed, who sneaks out to watch his best friend Damian compete in an underground boxing championship. As Creed III progresses, it delves deeper into these moments from Adonis' past, highlighting how Dame ended up in prison after Donnie impulsively attacked a man and fled the scene.
