Dr. Alphys (/ˈælfiːz, -fᵻs/ AL-feez, AL-fis) is a female, reptilian monster that lives in the lab in western Hotland. She is the incumbent Royal Scientist, a position she was awarded by Asgore after the death of her predecessor. Asgore hired Alphys because she told him that she had created a SOUL; in reality, she created a robotic body for a ghost.
