The daughter of Toph and an unnamed father, Lin is an Earth/Metal bender and the chief of police for Republic City. While Toph was a good friend of Avatar Aang, her daughter refuses to be nice to or even try to make peace with Korra. It is unknown why she detests Korra so much, perhaps she's just crabby. She appears to be middle-aged, has greying hair, pale-green eyes and a scar runs down the right side of her face. She is very uptight and commands a lot of metal-benders. She has apparantly inherited her mother's job because there are statues of Toph outside of the police center.
