The 45-year-old Suyin, or Su for short, is half-sister to Chief Lin Beifong and daughter of Toph Beifong. A well-traveled woman of many talents and skills, she's a powerful metalbender, a dancer and the leader of Zaofu, the city she built from the ground up. Family is of utmost importance to her — she is happily married to her architect husband and they have five children. Su has a checkered past and got into a lot of trouble when she was younger, resulting in a strained relationship with her sister Lin.

The voice cast includes David Faustino, P.J. Byrne, J.K. Simmons, Mindy Sterling, Seychelle Gabriel, Kiernan Shipka and Eva Marie Saint.

The news comes one day after THR broke that Nickelodeon would be bringing Legend of Korra to San Diego's Comic-Con.

In other news, the Blu-ray and DVD sets for Legend of Korra: Book Two — Spirits will be available July 1.
