marxvee | Undertale Hard Mode - Sans' Intro (FAKE) @Marxvee | Uploaded 8 years ago | Updated 9 hours ago
Not real, but it's how I'd picture it. While it's mostly recommended this would happen AFTER a genocide run, this could also possibly happen if Sans never made the promise with Toriel to not harm humans, just with different dialogue. I used debug mode to force the encounter. ⠀
