Much like her granddaughter, she has excellent martial arts skills, having trained in "Pang Lang Quan Kung Fu" in a Shaolin Monastery, to a level of mastery that surpasses even her granddaughter's martial art skills.
She always calls Kim by her given name of Kimberly and never shortens it. She also believed at first that Kim's "saving the world" is just a phase and will grow out of it, little knowing that Kim's saving the world is actually a lifestyle. She also refuses to see that Kim is now a teenager, and always dresses her in sweaters as she thinks Kim's habit of exposing her midriff isn't a good idea.
When Nana wants to ignore something, she will turn her hearing aid off, such as when Kim tried to justify her being a hero.
At first, Kim felt that this was because her grandmother was behind the times and didn't understand her. It wasn't until Dr. Drakken pitted them against each other through a mind control signal in the hearing aids of all of Miami's senior citizens that Kim learned the truth.
It then became apparent that Nana's objections came from the fact that she knew how dangerous such a lifestyle could be and that even grandparents would like something better for their grandchildren. She may have also seen a little too much of herself in her granddaughter (which she had known all along, because she had been Kim's age once). But it wasn't until Nana could see that Kim was more than capable of holding her own that she generally became more accepting.
- Although close captioning and pronunciation has her Kung Fu Style as "Pang Lang Quan", it is most likely "Tang Lang Quan", or Northern Praying Mantis Style—literally Praying Mantis Fist".
