Shadow Beasts were introduced in The Legend of Zelda: Twilight Princess in 2006 as servants of Zant that drop from Twili portals to hunt Link in groups. Their design came with inhuman vocalisations, and this screech signals a portal opening or a fallen Beast calling the others back to life. Clips of the cry spread through Zelda forums, YouTube edits, and soundboards alongside other horror game staples like the FNAF Jumpscare Scream, and it remains a shortcut for a supernatural enemy arriving.
