Bray Wyatt, performed by Windham Rotunda in WWE, introduced The Fiend in 2019 as a darker split persona built around the Firefly Fun House segments. Let Me In became the character's menacing catchphrase, repeated in promos and entrances before matches. Clips of the line spread among wrestling fans on social media and soundboards, where its short length and creepy delivery made it easy to reuse outside wrestling. It remains popular in horror edits and meme videos long after the original broadcasts.
