a poorly-photoshopped image of a bald nagito komaeda in a golden hall that appears at the end of the game undertale. Also known for the following copypasta:

"WHAT? That’s not Sansy. That’s some person from like Attack on Titan or whatever. The image is so poorly edited, and you can tell it’s a JPEG because of the white around it. At least they got the hall right… where Sans and Frisk have the final showdown in the No Mercy run of Undertale."
Dude, it's sans undertale!
What?
oh god he's here.
