Espionia

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

Canon
As Sonia only appears in Sonic Underground and for a short while in the Archie comics when Prime Zone Sonic visits the Underground Zone, and Espio is absent in both, the two have never met in canon. However, a character resembling Sonia can be seen sitting beside Espio in issue 134.

Similarities

 * Both have interacted with their versions of Sonic the Hedgehog and Knuckles the Echidna.
 * Both are enemies with their versions of Eggman/Robotnik.
 * Both have a purple/pink color scheme.
 * Both use some sort of tornado attack (Leaf Swirl for Espio, and Sonia Spin for Sonia).
 * Both are members of trios who are known to perform musically (Sonic Underground performs a song in every episode, and Team Chaotix uses Chaotix Recital as their team blast in Sonic Heroes).

Fanon
Espionia is a fairly popular ship, although they will most likely never meet canonically. Some fan fictions has somewhat romantic tensions in them. One of the most popular ships for both Espio and Sonia, its main rivals include Bartonia, Knuxonia, Espade, and Espicole. It is usually shipped alongside Manina.

Two notable DeviantArtists for this ship is ameth18 (who also ships rare pairings Manina and Mightoney, among others) and BeeWinter55. A fanclub was set up in October 2014, with three fan fictions currently. The SonamyxShadally fanclub has a separate gallery for this ship.

As of October 2020, AO3 has three fan works (with Neo Sonic Underground having two seasons as separate works). Wattpad has currently one section of Sonic Couples focusing on this ship. DeviantArtist Shojo-Skip wrote Chaotix Underground with this ship in mind, most parts can be read from a long fan fiction list of the MobiuanCouples group.
