Because of her mother's teachings in the importance of manners, Cream is a princess-like figure; she is very polite, graceful and well-behaved, speaks courteously (often referring to people as "Mr." and "Miss", followed by their first name) and does what she is told. With her politeness being like second-nature to her, Cream acts out her teachings with a cheerful smile on her face and a soft voice. Regardless of the situation and being used to getting what she wants, Cream never forgets her manners, even showing respect and offering a polite curtsy to her enemies, like Eggman, before attacking them with extreme prejudice.

Cream is sweet, honest, innocent and has a generally happy attitude. She is similarly very considerate, charitable and friendly, always eager to lend her friends a hand whenever the situation calls for it and tries to be close to everyone she meets. For this reason, she is loved by everybody. Cream is likewise extraordinarily brave, courageous and noble for someone her age, not afraid to face danger for the sake of those she cares about. She is likewise full of curiosity and has a thirst for knowledge. She is also not afraid to voice her anger and disgust, but never does so in a rude way.
