Ratatouille. She is voiced by Janeane Garofalo.
Colette is a very tough, assertive woman who is very hardworking. She is very fierce and strong, as shown when she is forced to train Linguini, and immediately sticks knives in his sleeves as she tells him she won't let a new trainee screw up all of her hard work. During her training with Linguini, she scolds him for taking his time while cooking and later threatens to kill Linguini if he can't keep his station clean. Colette herself states that the reason she is the only woman in the kitchen where cooking is regulated "by rules of stupid old men who make it impossible for women to cook" is because she is the toughest cook in the kitchen.
However, despite some of her tougher qualities, she is a firm fan and believer in Gusteau and his famous motto: "Anyone can cook." She has also memorized all of his recipes by heart. Her strong belief in his words causes her to defend Linguini from being fired by Chef Skinner, saying that it would betray Gusteau's words especially after Eclair said she liked the soup he made. Her belief in Gusteau's words is so strong that despite having initially thought Linguini was crazy to say that Remy (a rat) was the one revealed to be the cook, she goes back after remembering Gusteau's words and later works together with Remy (while the rest of the staff left after thinking Linguini was crazy) as a cook in Gusteau's and later in Remy and Linguini's bistro, La Ratatouille.
