Naruko is known for her determination. In the Avatar world, this would be a great asset. For example, when facing the Fire Nation's attacks or any other challenges, she would not give up easily. Her spunky personality would also add some fun to the group. She might be the one to crack jokes during tense situations, like when they are planning a battle against the Fire Lord.
Naruko is a very empathetic person. In the Avatar world, this would help her connect with different characters. She could understand Aang's pain of losing his people and be a great source of support for him. Also, her feisty nature would make her stand up to any form of injustice she sees in the different nations. For instance, if she saw the Earth Kingdom treating its own people poorly, she would speak up. Moreover, her ability to make friends quickly would help in uniting different groups within the Avatar world.
