10 Video Game NPCs Who Sneakily Knew EVERYTHING

Undertale is known for its meta humor, but this said, there are only two characters in the game who break the fourth wall consciously, and one of them is the fan-favorite, pun-loving skeleton, Sans.

Yes, the laid-back Sans is secretly the only one of the main guardians of the underground who knows exactly what the player is up to, which consequences are tied to their actions, and what he will ultimately have to do with you in the game's finale.

You won't see this side of Sans unless you commit to an aptly-named "genocide run", leading to a confrontation at the end of the game, but there are a few secret hints here and there that Sans lets out in-between chucking puns and budding with his brother.

For example, Sans can tell when you are saving or reloading, and shortly after you meet him for the first time, he will get oddly serious and say he would kill you on the spot if he hadn't made a promise to Toriel, alluding to the fact that he knows what you're capable of should you decide to go for a genocide run of Undertale.

He might be a goofy skeleton on the outside, but Sans is no bonehead.
