Sonichu medallion is a handmade item created by Chris Chan, which he has frequently worn for most of his adult life, aside from a good chunk of the time between 2010 and 2017 where he wore it more sparingly. Chris has worn this pretty consistently since then, usually alongside a necklace adorned with magic stones befitting of his pseudo-religious beliefs.

This medallion, of course, depicts Sonichu. Within the canon of Chris's Sonichu comics, the medallion is the source of the Anchuent Powers that allow Chris to assume his Electric Hedgehog alter ego, Chris-chan Sonichu.
