What is the name of Apollo Creed's son in the Creed films?

Apollo Creed's son in the Creed films is Adonis Creed. Born Adonis Johnson, he is Apollo's illegitimate son and later takes his father's surname as he begins building his own boxing legacy.

Adonis is introduced in Creed (2015), where Apollo's widow, Mary Anne Creed, adopts him after learning that he is Apollo's child. Although raised in comfort, Adonis feels drawn to boxing and eventually travels to Philadelphia to ask Rocky Balboa, his father's former friend and rival, to train him.

A common mix-up is the name Apollo Jr. Apollo Creed did have a son named Apollo Creed Jr. in the original Rocky continuity, but that character is not the protagonist of the Creed films. The modern series focuses on Adonis, played by Michael B. Jordan, across Creed, Creed II, and Creed III. His nickname, Donnie, is also frequently used in the films.
