Sonerci

Sonerci is the het ship between Sonic and Perci from the Sonic the Hedgehog fandom.

Sonic Boom (TV series)
In "Battle of the Boy Bands", Perci was one of the brainwashed Justin Beaver fangirls obsessed with his mind control music. She attended a Justin Beaver concert in which Sonic's band, Dreamboat Express, challenged him to a sing-off. Perci and the other fangirls were freed from the mind control after Sonic used a counter-frequency on Justin, then cheered on Knuckles' band under a new name, Dude-itude.

In "Fire in a Crowded Workshop", Tails went inside his smoking workshop and saw Sonic, Knuckles, Amy, and Perci covered in soot. Sonic tried to explain what happened to the workshop: Perci had gotten in a bike accident and hurt her arm. Sonic introduces himself to Perci and brags to being the "fastest hero in the world", "purveyor of justice", "righter of wrongs", and "eater of chili dogs", trying to win Perci over with is suave personality and overall loyalty towards the injured bandicoot. When they reach Tails' workshop, Sonic repaired her bicycle. Amy asked Knuckles for a pillow, which lead them to arguing who is the boss in the team. They fought for the pillow, despite Sonic's protest to behave, and suddenly, the workshop caught fire. Sonic was able to extinguish the fire with his super speed and some buckets of water, and blamed Knuckles for starting it. Knuckles disagreed with Sonic's version of the story and told his own version, with Sonic showing obvious interest in Perci. Amy, likewise, disagreed with his and she told her own version, this time with both Sonic and Knuckles showing off their interest in Perci. Aggravated by the contradicting points of view, Perci told her own version of the story that Sonic, Knuckles, and Amy were equally fretting over the accident. Tails revealed to them that accident was caused by his new security system that should have gone off. Resolved, Sonic, Amy, and Knuckles went out to get some food.

In "Mech Suits Me", Sonic, while riding in his mech suit, flirted with Perci and his twin sister Staci, to Amy's embarassment.

In "Three Men And My Baby!", Perci, Staci, and Zooey glanced at the passing Tails, Sonic, and Knuckles who are feeding Lady Walrus's younger son Chumley.

Fanon
Due to some proofs that can be considered "romantic" like Sonic's interest in Perci, Sonerci gained some fan-following.
