Trivia / Ben 10 S 4 E 6 Ready To Rumble

• Uncredited Role: Richard McGonagle as Four Arms, weirdly enough.
• Word of God: Eugene Son stated that the various weird looking wrestlers were originally intended as mutants, but after the more sci-fi route taken with Ben 10: Alien Force, he considers them alien hybrids, like the Plumber’s Helpers. However, this this retcon would later be undone, making them mutants again.
