* The "Sonic X" anime series: This show features Sonic and his friends traveling to Earth, where they encounter humans. They do not transform into humans themselves.
* Fan art and fan fiction: Many fans create their own interpretations of Sonic X characters in human form. These are not officially part of the Sonic X canon, but they can be found online and in various forms of fan art.
* The "Sonic Boom" series: While not directly related to "Sonic X," the "Sonic Boom" series features human characters who live alongside Sonic and his friends. This is a distinct series with its own storyline and characters.
So, while there's no official show about Sonic X characters in human form, the idea is popular among fans and has inspired a lot of creative works.
