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.

While the two have never met, Sonia and Espio are acquainted with their versions of Sonic the Hedgehog and Knuckles the Echidna, who have helped them in their battles against their versions of Eggman/Robotnik. Since the two are members of resistant groups who are fighting for their worlds' freedom. Along with Sonia and Espio being 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). As for their attack moves, both are able to use some sort of tornado attack (Leaf Swirl for Espio, and Sonia Spin for Sonia).
