You know that weird thing where characters get drawn with uncomfortably long and slimy sexy glowing ectoplasm monster tongues and bedroom eyes all the time? They invented that for Sans. It only shows up once in the game, when he uses his magic while he's going all-out during the genocide route final boss, but the fandom has exaggerated it to being a main feature of his.

The Undertale fandom was known to be disproportionately horny for nearly all the characters, but Sans' position as the fan favorite saw him as the most prominent subject of that horniness. The dramatic tension of the scene skyrocketed Sans into being the fan favorite, so much so that he eventually represented Undertale in Super Smash Bros. In this battle, Sans has a far more aggressive and involved attitude than in the rest of the game and reveals a surprising amount of raw combat power.

Eventually, this Human was killed and their SOUL captured.Īfter some time, it was decided that the monsters would use the SOUL TRAIT, LUST, in a fleeting attempt to raise the fertility of monsters and save their people.

About a decade after the son of Asgore and Toriel had been stillborn, a human fell into the Underground. Sometime after being sealed Underground, monsters began to suffer from widespread infertility, and their numbers began to dwindle.
