Lin Beifong is the Chief of Police of the Republic City Police Department, the daughter of Toph Beifong and Kanto, and the older maternal half sister of Suyin Beifong. Although her mother taught Avatar Korra's previous incarnation how to earthbend, Lin displayed no affection toward her when they first met. However, Lin's feelings toward the young Avatar changed when Amon and his Equalists made their public appearance and openly challenged the benders of the world. Lin is brave, loyal, and willing to sacrifice herself in order to do what she believes is right.
