Unlike the video game version of Princess Peach, the movie version of Princess Peach does not act as much in a refined manner and is more visually confident when fighting her enemies. She is very protective of her kingdom; she will not hesitate to defend it from anyone or anything that threatens or endangers it, especially Bowser. She's also shown to be very alluring to others, mainly toward her friends. 

However, like her counterpart, Princess Peach is compassionate, joyful, playful, patient, and still a bit graceful as shown with her interactions with Mario. She has a strong sense of curiosity upon meeting Mario, inspecting him to see if he was indeed human, and asking him questions about his world.
