Chief Lin Beifong

Her mother Toph taught Avatar Aang how to earthbend, but Chief Lin Beifong doesn't feel any special affection for the new Avatar. In fact, this metal and earthbending police chief sees Korra's arrival as the biggest threat Republic City has faced in recent times. Korra's reckless ways are constantly leaving Lin Beifong's streets in ruin, and this chief is determined to push the Avatar out of her city.
