Vivian Dolan or Butterball is a member of a wrestling organization called The Unlimited Class Wrestling Federation or UCWF. She was introduced to the UCWF due to her superhuman qualities and abilities which were given to her by the Power Broker.
Soon after Titania's defeat by the hands of Battleaxe, she was found murdered by The Scourge. Suspecting The Thing to be the cause of this, Butterball and the rest of the Grapplers attack him. In the middle of the battle, Sharon Ventura interfered aiding him by clearing him of all accusations.
Butterball was created by Mike Carlin and Ron Wilson in 1986 and first appeared in The Thing # 33.
