Jinora is a quietly reserved, intelligent, studious girl, much different from her younger, more rambunctious siblings. Out of Tenzin and Pema's four children, she is the calmest and most mature. However, she does like to tease her siblings from time to time, causing her sister to perceive her as "mean and bossy". Although still young, Jinora displays a great amount of courage, as she was willing to exchange her soul in favor of the world's well-being when she was being used as leverage to coerce Korra into opening the Northern spirit portal, as well as prolong the separation of her soul and body in order to aid the world by finding Raava.

A calm yet carefree girl, Jinora has a natural connection to the Spirit World.

Jinora enjoys reading historical fiction, as well as her father's journals chronicling his adventures with her grandfather, Avatar Aang, and the adventures of Aang and his friends. She also has an interest in playing Pai Sho and has begun to develop romantic interests in boys, which troubles her father greatly.

Jinora is the most spiritual in her family, believing that she had always had a connection with spirits. With the help of a group of spirits that she met, Jinora was able to enter the Spirit World with Korra.
