The Black Widow is a villainess in the videogame King's Quest VI: Heir Today, Gone Tomorrow. She is a deadly black widow spider that kills her own husbands.
Black Widow is encountered in her web by Alexander in the Book Garden. She claims to be the "femme fatale of all femme fatales". She wanted Alexander to marry her so that she could kill him. Alexander managed to snatch the part of the riddle book from her web without her noticing.
Black Widow loves meeting young men and she always makes deep expressions on them. She is proud of her web, even if she can't keep the wind from depositing parchment scraps into it.
Black Widow cannot be defeated or killed in the game, and she is still living in her web on the Isle of Wonder when Alexander becomes King of the Land of the Green Isles.
