Tailerci

Tailerci is the het ship between Tails 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 Tails' 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 Tails' band under a new name, Dude-itude.

In "Fire in a Crowded Workshop", Tails went inside his smoking workshop and discovers Perci, Sonic, Knuckles, and Amy covered in soot. Sonic told his own story of how the workshop caught fire, but Knuckles disagrees with his. Knuckles told his own, but Amy disagrees with his and she told her own. Aggravated, Perci told her own version of the story that Sonic, Knuckles, and Amy were equally fretting over the accident. Tails reveals to them that accident was caused by his new security system that should have gone off. Resolved, Sonic, Amy, and Knuckles went to get some food. Still on the workshop, Tails fixes Perci's bicycle, the latter saying "I like a guy who's handy." Tails opens his welding mask and blushes.

In "Muckfoot", Perci praised, "Way to go, Tails" after the whole village experienced Muckfoot mania.

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

Fanon
This ship is lesser-known than Tailsey; there are a handful of fan art alongside screenshots from "Fire in a Crowded Workshop" on DeviantArt.

Perci has a very small following in AO3.
