Skullgirls is a 2-D fighting game developed by Lab Zero Games and published by Autumn Games and Konami. Set in Canopy Kingdom, characters are fighting for the opportunity to control the mysterious Skull Heart, an artifact with the ability to grant wishes, albeit at a substantial cost. If he or she has an impure heart, even a selfless wish will be twisted in the most vile of ways: peace brought through brutality, eternal life through perpetual childhood, or a lost love returned as an undead monster. Hundreds have sought the Skull Heart, but so far none have been deemed worthy and spared its cruel power. Those judged impure are transformed into the fearful instrument of their twisted wish - the Skullgirl.
