Mangle first appeared in Five Nights at Freddy's 2 in 2014 as a broken, rebuildable version of Foxy taken apart by children in the pizzeria. Its jumpscare scream became one of the most recognisable sounds in the series because it is louder and more distorted than a normal voice line. As the games spread on YouTube and streaming, creators lifted the screech for fan animations, edits and reaction videos, and it stayed popular as a shorthand for an animatronic attack even outside FNAF gameplay.
