Ridley is the dragon-like space pirate who has been a recurring boss in Nintendo's Metroid series since the 1980s. Neo Ridley is the version fought in Metroid Fusion, released for Game Boy Advance in 2002, where an X Parasite copies Ridley's form. The boss's opening screech became a shareable clip on its own, passed around gaming and meme soundboards alongside other short stingers like the FNAF Jumpscare Scream. Its short length and extreme volume keep it popular for edits that need an instant monster reaction without any dialogue or music underneath.
