Mrs. Ego

Mrs. Ego is a minor character from the Disney-Pixar animated movie Ratatouille.

Ratatouille
When Anton Ego eats the ratatouille made by Remy, he has a flashback to his childhood when he remembes one day when he fell off his bike and hurt his knee. On that day, Mrs. Ego made him his favorite dish: ratatouille.

Remembering his mother's food changes Ego's personality from that of a cold man to a very cheerful man. By the time of the film's events, it's likely that Mrs. Ego is deceased.
