Chaos Sonic, or Chaos Metallix is the Metal Sonic that appears in Sonic Prime. While most expect him to be some upgraded version of Metallix, Chaos Sonic’s personality is exactly like Sonic, but evil. He can be cocky, annoying, but at the end he is still evil. The Chaos Council invested much into his creation, but rumor has it that Nine had a hand in his creation. Chaos Sonic also has his own three step plan after he deals with Sonic. That being: Destroy Sonic, Rebrand, and Diversify his merch.
