Shippings

Shippings are a practice within any fandom and that is no different with the Sonic the Hedgehog fandom. We like to call these fans "shippers" a fan who ships in their fandom. Then there is also people who don't necessarily ship but support ships that have already been shipped these are known as "ship supporters".

Canon Ships
Now, these ships are canon and have actually happened in canon Sonic media, whether that be the games, TV shows, or comics.
 * Sonally (Applies to SatAM/Pre-Genesis Wave Archie canon)
 * Sonamy (Applies to Boom canon)
 * Taimina (Applies to SatAM/Archie canon)
 * Taizoey (Applies to Boom canon)
 * Knuxsu (Applies to SatAM/Archie canon)
 * Antunnie (Applies to SatAM/Archie canon)

Fanon Ships
These ships are not canon in any Sonic media, and fans just assume they kind of are and ship them even though they are not officially canon.
 * Sonamy
 * Sonally (Post-Genesis Wave)
 * Sonmina (was sort of canon in the Archie comics for a while)
 * Sonfiona (like Sonmina, was sort of canon in the comics)
 * Sonilidog (a parody ship supported by WheatleyGAMING)
 * Sonaze (briefly teased in Sonic Rush Adventure and Sonic and the Black Knight)
 * Taifiona (was thought to be canon in some issues of the Archie comics, but is now fanon)
 * Tailsmo (was canon until Cosmo died after Season 3 of Sonic X)
 * Taiream (despite that Tails and Cream never had romantic moments together in any official Sonic media.)
 * Knuxouge
 * Shadouge
 * Shadamy
 * Silvaze

Crossover Ships
These ships are between characters from two or more different series. They're arguably the worst type of fanon ship.
 * SonDash (between Sonic and Rainbow Dash. Despite that Sonic and MLP characters never met in official media, this is one of the most popular crossover ships.)
 * Sonuli (between Sonic and Fuli from The Lion Guard. There have been a few fans who ship this. Easily the worst ship involving Sonic since most take this ship very seriously.)
 * Shadrek (Originally a parody ship between Shadow the Hedgehog and Shrek that was made for the sake of memes, people are now taking it seriously for some reason.)
