First, please don't refer to me as if I was Xeno. His name may be based on my online name, that doesn't mean I'm role-playing as him, I'm a real person.

And Xeno met Sonic & Amy during the events of Sonic Forces, an atta k separated him from his aunt Lutèce and injured him he was found by Sonic and Amy, and Amy decided to bring him to the HQ to take care of him.
