Marshmello hides his identity on and off the stage. In public, he always wears a white marshmallow-shaped helmet to hide his face, much like Daft Punk or Deadmau5 do during their performances. He also wears all white from head to toe to better resemble an actual marshmallow. The surface of his white marshmallow-shaped helmet is covered with LED lights, which extends the light show to his head! The elements of mystery and 'cuteness' of the marshmallow costume made is meteoric rise viral.
