Dorothy Bigbottom is a character in the Grand Theft Auto series who is mentioned on the official website of Grand Theft Auto: Liberty City Stories, although she does not  have an appearance in any game.

Dorothy Bigbottom is a resident of Liberty City who e-mails the Liberty Tree offices complaining about the 'edutainment' game, Pastmaster, which she claims ruined her marriage. She complains that her husband role plays history re-enactments and believes he is Ghandi and keeps trying to help people.

She sums up the difference the game has made by saying: "The real problem is he's no longer the rather sweaty, meat eating investment banker who specializes in hostile takeovers and obsesses over pornographic literature that I once married. Now he is a mild mannered vegan with a belief in the innate goodness of humanity and a desire to help people. This is not the man I married".
