Shadpio

Shadpio is the slash ship between Shadow the Hedgehog and Espio the Chameleon from the Sonic the Hedgehog fandom.

Canon
Shadow and Espio first met in Sonic Heroes, started out on unfriendly terms as their teams fought each other. However, they later teamed up to defeat Metal Sonic.

They were allies in Shadow the Hedgehog if Shadow got to Mad Matrix. In that level, Shadow had the option to help Espio access the four terminals. Afterwards, no matter which mission Shadow did, Espio and Shadow fought Egg Breaker. In the Last Story, Espio, along with Vector and Charmy, hacked into the ARK's computer in order to activate a message that revealed the truth about Shadow.

They met again in some later games. In Sonic Rivals 2, the two were rivals. In Sonic Generations, they cheered the Sonics on and later attended his birthday party, although no interactions are shown between the two. Shadow and Espio were also among the ones fighting Infinite in Sonic Forces.

Fanon
Espio and Shadow are sometimes shipped, although the pairing is not as popular as many other Shadow pairings such as Shadouge and Shadamy.
