With the Creed movies are a continuation of the Rocky series, it's not a surprise that a number of Rocky characters have returned for the Creed movies. The Rocky franchise is densely populated with beloved boxers, lovable side characters, and despicable villains; naturally, the Creed series brought some of the original films' most popular characters back to the big screen. Some of these Rocky characters play huge roles in the Creed movies, while other characters have blink-and-you'll-miss-it cameo appearances.
