Espionia

Espionia is the het ship between Espio the Chameleon and Sonia the Hedgehog from the Sonic the Hedgehog fandom.

Canon
Sonia appears exclusively in the Sonic Underground series and the Underground Zone in the Pre-Super Genesis Wave Archie Comics (excluding cameos), while Espio appears in multiple other canons. The two have never appeared together.

Fanon
Despite the two characters existing in separate canons, the pairing is fairly popular for both characters. Espionia is commonly shipped alongside Manina.

Fanwork of this pairing is mainly made by DeviantArt user ameth18, who is known for uploading fanworks featuring his favorite Sonic pairings.
