Anton Ego

Anton Ego is a dour, humorless food critic, whose reviews can make or break a restaurant. We're sure his nickname "the Grim Eater" and the fact that Gusteau died mysteriously after Ego downgraded him from five stars to four are just a coincidence. The restaurant then lost another star with his death.

When he had heard the Gusteau restaurant was rising in popularity with Remy as the cook, he personally offers a challenge in which they must deliver their best shot to impress him. Remy serves a simple peasant dish, ratatouille (a play on words and the title namesake) which is so brilliant it reduces Ego to his childhood memory of his mother cooking. Tears flow from his eyes, and when he requests to see the chef, Linguini and Colette tells him to wait after the customers have gone. When closing hour is struck, Linguini reveals Remy. Ego believed at first it was a jest, but after viewing Remy perfectly recreate the dish, he thanks them for the meal and quietly leaves.

A changed man, he presents a shining review of the restaurant, and in particular, the chef (whom he does not name). Ego then lost his job and credibility when Gusteau's was closed down due to a rat infestation. But Ego lead a successful and a happy life as an investor and regular patron of a small bistro, with queues around the block and where the cook is a small rat.
