A human named Frisk, who would make it their personal mission to show the monsters of the Underground what true love is, and how it is more effective than lust. Ghosts are the only exception to this, as they lack a physical form.Įventually, a new human fell into the Underground. The duty to preform the injections was set to Doctor Gaster, who was to inject everyone of age with the LUST, including himself.Īlthough it was never expressly stated whether these injections succeeded in raising the fertility, what the injections did manage to do was make sure every adult monster in the Underground was put into a 'constant state of heat'. 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. This human, named Chara, had the SOUL TRAIT of LUST, and soon after entering the Underground began murdering all monsters that crossed their path for their own sadistic pleasure.
