Korra, from "The Legend of Korra," is confident, headstrong, and determined. She can be impulsive and struggles with her identity as the Avatar, but she grows throughout the series, becoming more compassionate and wise.

In terms of cartoon figures who could fight her, characters like Aang from "Avatar: The Last Airbender" could provide a challenging match due to their similar bending abilities and shared Avatar lineage. Other powerful characters from different series like Goku from "Dragon Ball Z" or Naruto from "Naruto" might also offer formidable opponents due to their immense strength and abilities.
