Diet Ultra Violet was a Mountain Dew flavor variant, and the first to be released exclusively in diet form. Its tagline was "Zero calorie DEW with a Flash of natural and artificial Mixed Berry flavors", while its planned FanDEWmonium tagline was "Mixed berry-flavored diet DEW with other natural flavors."


Diet Mountain Dew Ultra Violet was released for a 12 week period beginning in August 2009 and lasted through 2010, and was then discontinued. It also saw a comeback during the FanDEWmonium campaign and was a semi-finalist, losing to Diet Supernova and finishing in 6th place.


Diet Ultra Violet was a mixed berry flavored soda, and, as its name suggests, was violet in color. It was advertised as a "Flash of Natural and Artificial Mixed Berry flavors."


  • Many fans who tried this flavor for its limited run found it very similar to Revolution, due to their similar mixed berry flavoring.
  • Diet Ultra Violet was the very first diet-exclusive flavor of Mountain Dew, as it lacked a non-diet counterpart. However, some fans consider Revolution to be somewhat of a non-diet version of Diet Ultra Violet purely because of their similar flavors.
