- “This is me. I think it's apparent that I need to rethink my life a little bit. What's my problem? First of All, I'm a rat. Which means life is hard. And second, I have a highly developed sense of taste and smell.”
Remy is a rat who simply adores food and its quality. He befriends a spectral representation of his hero, the late Auguste Gusteau. Due to his love for food, he has a strong sense of smell, and his father Django appoints him as an inspector amongst the rat's clan after Remy stops him from eating a poisoned apple core, so the rats will no longer die to toxic food. Remy's gift with food allows him to be able to identify the different ingredients in a dish, and he always tries his best to make delicious high-quality food. He also has an interest in humans, due to how they prepare food in such an exquisite manner, and soon becomes quite close to one particular human, Alfredo Linguini, who affectionately calls him "Little Chef" and cannot cook.
He is not a typical rat, and his personality is more like that of a human, as he walks on two feet instead of four. What he thinks of his talent is a bit of modesty, as shown when Linguini asked him if he could actually cook. Towards the fact that he is not really a typical rat, this concerns his father excessively, and always ends up in an argument with him to do with his ways.
His overall dream is to become a chef. He is incredibly skilled and talented in cooking (possibly beyond the likes of Gusteau), never failing to impress diners (including feared top food critic Anton Ego) with his excellent quality dishes, to the point that Linguini (who is controlled by Remy) becomes the star chef of the restaurant.
In the beginning of the film, it is revealed that Remy possesses a very strong sense of smell, able to deduce various ingredients in food. His brother Emile is readily impressed, while his father, rat clan chief, is not but pleased when Remy is assigned as rat poison checker when he almost ate a poisoned apple core, sniffing every bit of garbage for poison, despite the fact that job is essential for the survival of the rat clan. Remy's father is also annoyed about Remy's attitude towards eating garbage, Remy claims that is unhealthy for rats and they ought to try to take the good food found in the kitchens and pantries of the humans. Therefore, Remy makes constant forages to the nearest kitchen, in an old lady's house in the countryside, where the clan is also located. Remy is also able to learn to read and understand the human language. Remy idolizes the famed chef, Auguste Gusteau, with his motto: "Anyone can cook!"
With his sense of smell, Remy slowly realizes how to improve food by combining tastes together. One day, he and his brother Emile were smoking a mushroom by the chimney, before being struck by a flash of lightning. Impressed by the popcorned mushroom, the two venture into the kitchen for saffron. The old lady is asleep, but a TV is on where Remy hears the news that Gusteau has died. The old lady awakes, sees the rats, and promptly produces a shotgun where she blasts the walls and roof. Her inaccurate shooting, however, brings down part of the ceiling where the entire rat clan lives. Remy's father calls for a Dunquerque style evacuation, fleeing out to a stream and paddling off on rubbish. Remy runs back to grab a Gusteau cookbook and flees, trailing behind.
He paddles into the stream, under fire from the old lady but loses sight of the clan in the sewers. The sewers contained rapids and displaying incredible water physics, Remy is alone. Absentmindedly, Remy flicks through his cookbook's pages where an illustration of Gusteau comes to life, animated by Remy's lonely imagination. Gusteau instructs Remy to go out and look for food, Remy complies and witnesses aspects of Parisian life before surveying the magnificent night scenery and finding himself located right next to Gusteau's restaurant.
Remy climbs onto the restaurant's skylight and sees the working of a quality kitchen, where he witnesses Linguini, a clumsy garbage boy, spill a pot of soup and stuff water and various random ingredients to make up for it. Remy is horrified by this sacrilege to good food and falls from the skylight.
Almost getting roast, cooked, chopped and seen, Remy gets to the soup undetected and was about to make good his escape via an open window. He halts and then proceeds to add ingredients into the soup, and was caught red-handed by a stunned Linguini. Remy was hastily hidden away when the restaurant's new owner Skinner sees a soup ladle in Linguini's hand and berate him for cooking. The soup is served to Linguini's dismay but proved popular to a critic. Remy, pleased, was about to escape but was caught. Linguini was told to hastily dispose of him, trapped in a jar, and he cycled to the River Seine to dump him.
Linguini was about to drop Remy but desists, noticing that Remy could understand him talking. Linguini quickly figures out that he can not cook, while Remy can. Linguini releases him and takes Remy into his apartment. There Remy learns a way to work with Linguini to cook while Remy can remain covertly hidden which is to use Linguini's hair to control Linguini like a puppet.
Remy helps Linguini recreate the soup to prove to Skinner that the success was not a fluke on Linguini's part but Remy's talents remain anonymous. When Skinner sees the soup he gives Linguini the cooking job but still is suspicious wondering where Linguini suddenly got his new talents. While seeing Linguini work he sometimes spots Remy with him but when he looks again Remy has vanished deeply confusing Skinner. Both Linguini and Remy are unaware that Skinner has been spying on Linguini and secretly taking some of Linguini's hairs for his lawyer to examine due to the fact that Linguini is Gusteau's son and the owner of the restaurant. This would challenge Skinner's hopes to continue his new frozen food line used in Gusteau's image.
When Remy learns this revelation, he steals the documents but in return is chased by Skinner. Remy climbs aboard a boat but Skinner refuses to lose and pursues Remy boat by boat ending with Skinner accidentally falling into the canal when jumping between two boats, and seeing Remy run back to the restaurant with the documents. Later that day, Skinner loses the restaurant's business interests, and with it the restaurant and frozen food lines. Linguini takes control as the rightful owner and Skinner either is fired or resigns not wanting to work under Linguini. Linguini also provides Remy with a new wonderful posh apartment to live in with him.
One night, Remy unexpectedly reunites with his family who believed him to have died in the rapids of the sewers. Django asks Remy to stay but Remy shows his loyalty to Linguini having bonded with his new human friend while being absent from his rat colony.
However, Remy gets confused when he sees Linguini bonding with Colette, the only woman cook in the kitchen, and crediting his talents to her. Remy gets attention from Linguini and gives him a wake-up call reminding him of Remy' true part in the cooking. However, Linguini is unconvinced in it and throws Remy out. In retaliation, Remy lets his family raid the kitchen one night but Linguini, wanting to reconcile accidentally discovers them and angrily throws them out.
Remy is so guilty that he again ditches the family to think about what to do now, at the apartment. The news then breaks out that one of Gusteau's mortal rivals; food critic Anton Ego who gave Gusteau's a scathing review in the past that eventually resulted in Gusteau's death; will come again to review the restaurant. The next evening, Remy tries to wait for the perfect moment to help Linguini or try to reconcile but is captured by Skinner who uses blackmail to order Remy to create a new successful frozen foods line. Emile sees what has happened and brings Django to help him free Remy from Skinner's limousine. Linguini realizes that he cannot work on the food without Remy and when Remy returns Linguini is so happy to see him again that he is forced to admit to the staff the truth. In reply, the staff all quit their jobs believing that Linguini is insane. Colette initially quits her job also but returns when remembering her idol Gusteau's motto: Anyone Can Cook.
With help from Remy's colony, Linguini, Colette and Remy present to Anton Ego and a disguised Skinner a version of an ancient dish, ratatouille. Anton Ego loves it when realizing that his mother made it for him when younger and now a changed man, Ego asks for the chef to thank for the dish. When Skinner sees that Ego is impressed, he tastes it and when trying to find out who cooked it, he finds out that Remy's rat colony did it. Skinner is then locked in the room with a health inspector Skinner had previously summoned. Ego is told to wait until all customers have left, to see the chef that made it. Hours later, they reveal Remy to Ego. At first, Ego thinks they are joking but when they explain and demonstrate it, a stunned Ego thanks them, walks back home and writes a wonderful review, praising the restaurant.
The next morning, Ego puts his review in the newspaper but because Skinner and the Health Inspector had to be freed, word got out there were rats in the kitchen, leading the restaurant to be closed and Ego to lose his job and his credibility due to praising a restaurant inspected by a horde of rats.
Although very disappointed to lose a very successful, legendary restaurant to Skinner and the Health Department, Remy, Linguini and Colette take it well and to recover from their business collapsing, they buy out a new building and there they start a new restaurant modeled after Gusteau's called La Ratatouille to continue the Gusteau legacy. Ego becomes a small business investor and helps Linguini and Colette fund the restaurant with Linguini as the waiter, Remy as the head chef, Colette as the sous-chef, and Ego as the sponsor. The rats are then shown hidden in the restaurant at a vantage point, enjoying some food as Remy is telling them the whole story.
In the animated comedy short, Remy and Emile teach the viewers about the history of the rat in order to bring a better understanding between the two species.
Remy, portrayed by Trevor Roberts, appears in human form in the seventh season, as the caterer hired by Victoria Belfrey and later an employee at Roni's bar. Knowing that other animals like Jiminy Cricket and Gus were transformed into humans by the curse in the show, it was possibly effective for Remy as well.
Remy will appear in the game as a minigame-exclusive character. He is playable inside the minigame "Remy's Delicious Restaurant" found at Twilight Town. When Sora collects enough ingredients on his journey, he can take them to Remy to help Sora cook a full-course meal. Succeeding in making the meal with Remy increases Sora's stats for a duration.
Remy makes appearances at the Disney theme parks, especially in Disneyland Paris, and at the EPCOT France Pavilion at the Walt Disney World, he is often seen in Pixar-based entertainment including The Pixar Play Parade at Disney's Hollywood Studios. Remy is the star of his own segment in the Disneyland Paris show, Disney Dreams!
Remy is the official mascot in the diner Chef's De France in Paris at EPCOT, and walks around the diner with somebody by his side visiting the customers' table to table with a few jokes and surprises.
- Remy was listed #41 in Empire Magazine's The 50 Best Animated Movie Characters.

This is his second voiceover work for Disney/Pixar after voicing Professor Dementor in episodes of Kim Possible. A little bit of his "Dementor" voice can be heard during Remy's glee over the cooked mushroom.
