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 saw Perci, Sonic, Knuckles, and Amy covered in soot. Sonic told his own version of the story of how the workshop caught fire, but Knuckles disagreed with his. Knuckles told his own version, but Amy disagreed with his and she told her own version. 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, leaving Tails and Perci the only ones inside the workshop. As Tails fixed Perci's bicycle she said in a flirty manner, "I like a guy who's handy." Tails opened his welding mask and blushed.

In "Muckfoot", after Tails' discovery brought Muckfoot mania to the village, Perci praised him for the effort.

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 younger son Chumley.
