Mareach

Mareach is the het ship between Mario and Princess Peach from the Super Mario fandom.

Canon
As shown with Mario and Luigi: Partners in Time and Yoshi's Island DS, Mario and Peach have known each other since childhood. Both were destined star children kidnapped by Kamek and saved by Yoshi. Back then, they would have play dates and go on adventures together.

As they grew older, Mario would begin to rescue the princess from Bowser and other enemies. For almost every rescue, Peach would reward Mario with a kiss, cake, or both. However, the Super Princess Peach, the roles are reversed in which Peach rescues Mario from Bowser. She also sent Toad to look for Mario in Luigi's Mansion. Peach is also a playable character in Super Mario 3D World who helps Mario save the Sprixie Princesses.

Mario and Peach's relationship is teased constantly throughout the series. In official art for Mario Party Advance, it shows the duo trying out a love meter gadget. On the screen of the Gameboy Advance, it says their relationship is at 100%. When partnered together in Mario Party 5, their team name is "Cutest Couple." Those around the pair have also taken note. For example, Rosalina refers to Peach as Mario's "special one." Early comics such as Super Mario Adventures even have Peach dreaming of a marriage with Mario. Despite all of this, in the second episode of Send your Letters to Mario, he states they are only friends. Super Mario Odyssey also has Peach refuse both Mario and Bowser's gifts due to their behavior. She does appear to forgive them both later, though. It is likely there are mutual feelings, but a romantic relationship has not formed yet.
