Entity S A N S

Now, Undertale is a game where you discover monsters and csn befriend them, including Sans, the lazy skeleton whos well known for his boss fight at the end of a kill all route. So, the Five Nights At Wario's inspiration for this isnt VIRUS, but both Entity M A R I O, an enigma in WarioWare or the building that would be WarioWare; and Nightmare Wario, or Demon Wario, being a secondary disguise of Emma, the embodiment of the curse that fell on Wario and Co. In this, Entity S A N S is another disquise of Emma. Entity S A N S is a character one likely won't encounter head on in the Underground, but rather hidden in the shadows, ensuring you dont destroy too many if its VIRUS.
