Soneach

Soneach is the het ship between Princess Peach and Sonic from the Super Smash Bros. fandom.

Canon
Sonic the Hedgehog and Princess Peach met each other in the Mario and Sonic at the Olympic Games and the Super Smash Bros. series, starting with Super Smash Bros. Brawl.

They have many differences in personality--Sonic fights against hordes of robots while Peach usually gets kidnapped by Bowser. Even though there have been times were Sonic himself has gotten himself captured and has to rely on his friends to save him, like Peach commonly does. There have even been a few times where Peach does whatever she can to save her friends. Just Peach has been part of a racing game that has her going at high speed in a go-kart, one of the Sonic games of a racing element requires the said blue Hedgehog to use a type of hover board. Along with Peach learning use to drive surfboard in one of the SMB TV series episodes. In Sonic Underground, Sonic has a sister and is of royal blood, like Princess Peach is beside her sister.

Both Sonic and Peach reside in worlds that are home to none-human people, but the two do have human friends and their TV shows even Sonic and Peach stepping into the human world on Earth. One of their main iconic friends have red as their signer color, and even though Peach doesn't know that many raccoons like Sonic does, Peach and her friends are able to gain raccoon ears and tails to help them fly. Like Sonic's fox friend. When it comes to Sonic and Peach's main enemy, both Dr. Eggman and Bowser want the two out of the way so they could complete their self gain goals. Which is why Peach is commonly kidnapped and Sonic makes sure that he is able to avoid getting destroyed, all while not letting Dr. Eggman and Bowsers' actions towards the two get the better of them. Thanks to the love and support of their friends who are always there for Sonic and Peach.

Fanon
With Peach commonly being featured as a Denzel in distress, while Sonic is viewed as a hero who's speeds allow him to save and protect those in need at anytime, fans uses these facts when they ship Sonic and Princess Peach together. Since Sonic has been acquainted with a princess who he had saved from Dr. Eggman, while Peach has been shipped with non-human characters, where one of them is close to Sonic's height, along with Peach's using items to grant herself powers just as the Chaos Emeralds serve as Sonic's power-ups, it allows Soneach fans to see those traits as ways for Sonic and Peach to get along with one another. There have even been fans who rival Soneach with Mareach, Sonamy and the main Sonic/Mario crossover ship SonMario, since Mario and Amy have been featured in a few Soneach fanart and videos. Some of these YouTube videos have Sonic take Mario's place in Peach's stories as the blue hedgehog saves the Princess from Bowser, instead of Mario. Along with there beings videos that have Sonic "stealing" Peach's heart from Mario or Sonic and Mario switching girlfriends with one another, for fun.

In Mugimikey's video Sonic Meets Mario, Mario found out that Peach is dating Sonic, thus making the plumber jealous and furious. Peach also called Mario a "red, short Luigi" here. Sonic kept taunting Mario by playing with Peach's buttocks and boobs. Thus Mario broke down and Sonic reassured him and suggested the plumber to date Bowsette.

Soneach may not be the most popular ship in the Super Smash Bros. or the Sonic/Mario crossover fandom, it still has a few loyal fans. Who support it on AO3, FanFiction.Net, DeviantART, Instagram, Twitter and a few other websites that they can use to show their support for the ship. Because both the Mario and Sonic at the Olympic Games and Super Smash Bros. series are canon universes that allow Sonic and Peach to meet and spend time together, most fans like to focus their fan-made work of the ship around those two games series.
