Nightmare Wario is a final antagonist from Five Nights at Wario's 4. He resembles Wario without a head, but with visible facial features. He oftenly fades into the TV, and to stop him, go to a tab and then click 'Stop Demon W'. The W appears to stand for "Wario".


He has the same appearance of Wario, but has no head. This is similar to Mario.

He could also be based off of how Wario looks in FNaW 3.


Nightmare Wario will start on Night 5, and will periodically fade in on the left side of the TV. The only way to stop him is to go to the menu bar, go to help, and click on "Stop Demon W". If Nightmare Wario becomes completely visible, he'll jumpscare you.
