Sonouge

Sonouge is the het ship between Sonic the Hedgehog and Rouge the Bat from the Sonic the Hedgehog fandom.

Canon
Even though both Sonic and Rouge are good friends with each other's rivals, the two haven't been shown to dislike each other. In Sonic Generations, Rouge is one of the guests at Sonic's birthday party and Sonic treats her like his other friends.

Occasionally, Rouge has been seeing flirting with Sonic but no romantic feelings between the two are shown.

In Sonic Generations, one side mission in Seaside Hill involves Rouge helping Sonic by making Egg Pawns fall in love with her. The level has a romantic design in this mission.

Fanon
Sonouge is not as popular as other ships such as Sonamy and Sonally for Sonic and Knuxouge and Shadouge for Rouge. The ship is sometimes shipped alongside Shadamy.

Other times, it is shipped alongside Silvamy and Shadaze, where each pairing represents common traits. Sonic and Rouge represent freedom.
