Genario

Genario is the slash ship between Geno and Mario from the Super Mario fandom.

Canon
Earlier in the story of Super Mario RPG, Bowyer―not to be confused with Bowser―attacks Red Rose Town with paralyzing arrows that force its residents to stay indoors. In one of the town's houses, Mario decides to play with a boy named Gaz with the toys he has. However, one of them ends up knocking Mario out due to its laser canon. This very doll ends up being chosen by a single, star being in the night.

The next morning, Gaz reveals to his mother that the doll had began to walk around. While the mother doesn't believe him, Mario decides to find the livid toy. Thus, Mario and gang set out into the forest.

Throughout this time period, Mario follows the wooden toy around until they reach Bowyer. Here, the doll challenges Bowyer to a duel in order to recover one of the Star Pieces. Bowyer refuses and attacks, but Mario stomps on the arrow in mid air. Thus, the duo fight together to stop Bowyer.

After the fight, the doll introduces himself as '♥♪!?.' Due to it being nigh impossible to pronounce, he decides to go by the doll's name, 'Geno.' Geno explains he is a star spirit tasked with fixing the Star Road and that he choose the doll's body due to its strength. He then proceeds to join Mario on his adventure.

After the Smithy Gang is defeated and all Star Pieces are collected, Geno leaves the doll's body to return home. Its lifeless body can be seen behind Mario and co. on Vista Hill.

Fanon
The ship formed from Geno's status as a fan favorite character, Mario saving Geno from Bowyer, and their cooperation with each other.
