Lin Beifong is one of the better protagonists in the Legend of Korra. She’s the chief of police and daughter of Toph Beifong.
I was a bit shocked she dated Tenzin in the past and it didn’t work out.
She’s a talented metal bender and she did well training Korra to be the Avatar in her own way.
I was sad when Amon took her powers but I was happy when Korra figured out how to restore them.
She does reunite with her mom and sister for some touching, yet bitter reunions.
