Sophie Kane is the Daughter of Sweet Tooth in the 2012 Twisted Metal game.
She comitted suicide after she was almost murdered by her father. after the tournament, Calypso goes to Sophie (and Sweet Tooth's) grave after Charlie digs Sweet Tooth's mask up and drops a bag into the grave saying "Take your time, the journy back can be quiet unnerving..." soon... Calypso is greeted to the sigh of a female version of Sweet Tooth, Sophie, who is dressed like Sweet Tooth now, and with a belly ring with a demon head, this might have revived her. she is now loyal to Calypso. The Preacher said at the intro (through the radio talking to the DJ) "Once they are revived, they are forever loyal to Calypso."
