SCP-450

SCP-450
SCP-450 is a unique YouTube screamer that despite its name, has nothing to do with the SCP Foundation's website or information. This video begins with a warning message that the materials in the video may damage one's health and to watch at your own risk. After that message, a dark-brown hallway is shown with eerie music in the background.

At 0:50, a picture of a cat accompanied by a meow pops up and afterwards there seem to be "credits" (THANKS FOR WATCHING! Prepare to **** bricks >;3). Immediately after this line appears from the bottom, a flurry of well-known screamer faces, like Regan MacNeil, the Tic-Tac Toe screamer zombie, the Sajjad Ali banshee, and Pazuzu, pop up and zoom to the viewer in a fast slideshow fashion with accompanying screams. The screen then becomes black.

One second later, the face of Jeff the Killer comes up. Again, after that, Regan MacNeil pops up again with yet another scream while the face zooms up and seemingly "headbutts" the screen. After that the video ends.
