Jaq and Gus are a pair of mice who appeared as the two deuteragonists in Cinderella and its two sequels. Both Jaq and Gus were voiced by the late Scottish actor James MacDonald, who also voiced Bruno the dog. In the sequels, Jaq is voiced by Rob Paulsen, and Gus is voiced by Corey Burton. They were also once voiced by Frank Welker in a McDonald's commercial for Cinderella toys in 1987.
Jaq (also known as Jackson Checkers) is a slender brown mouse wearing an orange jacket, red turtleneck, red hat, and brown slippers. He acts as the leader of Cinderella's mouse friends and proves to be a good one at that.
Octavius (also known as Gus or Gus-Gus) is a portly brown mouse wearing a yellow shirt, green hat, and brown shoes. He is Jaq's best friend and is rather dim-witted compared to his buddy. Other than his friends and family, his number one priority is filling his belly.
Cinderella rescues the mice from traps and the cat Lucifer and dresses and feeds them. They perform many favors in return. Jaq seems to be one of the leaders of the mice, planning strategies to avoid the cat, sneak food, and help Cinderella with her ball gown. The other mice gladly follow his lead. Jaq is thin, with scruffy hair, and speaks a fast kind of pidgin English. Gus appears in the first scene of the film, trapped shivering in a cage where Jaq finds him and brings Cinderella to rescue him. Cinderella names him "Octavius," and calls him "Gus" for short.
Jaq and Gus are two of four mice that the Fairy Godmother transforms into stallions so that Cinderella can attend the ball, but at the stroke of midnight, they are transformed back into mice. Later, Jaq and Gus are responsible for stealing the key to Cinderella's room from the wicked stepmother, Lady Tremaine, and freeing Cinderella to try on the glass slipper, which of course fits. While trying to steal the key, Jaq is stuck in Lady Tremaine's pocket. Gus gets trapped in a tea cup and Lady Tremaine offers some tea to the Duke, with Gus inside. She begins to pour tea into the cup and it drops towards Gus's belly. Gus sucks in his belly to survive, trembling and sweating, but in a moment the Duke says he wants none, the tea lifts, and Gus is safe (though he gets his butt burnt by the tea later when they get the key). They are last seen in the film in tiny palace uniforms, eating and waving at the wedding of Cinderella and Prince Charming.
Cinderella II: Dreams Come True
Gus and Jaq make their second appearance, living in the castle along with all the other mice. Gus has an idea to make the new book of stories to replace the old one. In Cinderella's Story, Jaq and Gus aided Cinderella to prepare for the ball and gave her support when she underestimated her abilities. In Jaq's Story, Jaq, feeling useless, wishes that he were a human; Fairy Godmother grants this wish and Jaq tries to help Cinderella and the others prepare for the fair until he realizes he liked being a mouse better and returns to normal. In Anastasia's Story, they attempt to help their old nemesis Lucifer win the affections of a snobby female cat named Pom Pom (the mice's, and probably Bruno's, new nemesis) in the castle in the hopes the cats will then leave the mice alone.
Cinderella III: A Twist in Time
In Cinderella III: A Twist in Time, Jaq and Gus appear as the only mice in the movie and make their opening appearance helping the Fairy Godmother prepare for Cinderella and the Prince's anniversary party. After Lady Tremaine reversed time and made the slipper fit Anastasia's foot, they helped Cinderella search for the Prince, wreaking havoc in the palace kitchen in the process.
They discover Lady Tremaine's use of dark magic by witnessing her cast a spell on the Prince to forget Cinderella and think that he danced with Anastasia. In a plan to steal the wand back, they succeed in taking the wand from Lady Tremaine, but she has Cinderella arrested with a banishment sentence before she can lift the spell on the Prince.
Jaq and Gus manage to convince the Prince that Cinderella is the right girl through the catchy show tune "At the Ball". They later help Cinderella put on her wedding gown, but the three are magically sent away by Lady Tremaine, who assigns Lucifer the cat to drive them in a pumpkin carriage over a cliff. After they narrowly escape their deaths, Cinderella, Jaq, and Gus return to the palace, where the mice attack the entrance guards to let Cinderella through to the wedding. After Lady Tremaine is defeated, Jaq and Gus are seen celebrating Cinderella and Prince Charming's wedding.
The mice are last seen in Cinderella III during the closing credits in a picture with a very decorated King, one with them stuffed with cheese, Gus in a rather sophisticated uniform, and the final picture in a photo booth style series with Cinderella, the Prince, and the two mice.
Gus and Jaq are the only mice to appear in the film, while all the other mice are absent due to some unknown reasons, presumably due to the budget cuts in animation.
Once Upon a Time
Gus appears in Storybrooke as an engineer named Billy, who became smitten with Ruby (Red Riding Hood) in the episode "The Price of Gold". In "Child of the Moon", Billy tries to ask Ruby out on a date at Granny's Diner, telling her he was once Cinderella's mouse friend Gus in the Enchanted Forest, and when the curse hit, he became Billy. Unfortunately for Billy, Belle pretends that she and Ruby are having plans later so she will not have to be with Gus. The following day, Ruby, David (Prince Charming), and Grandma find that Ruby did in fact turn into a wolf, and seemingly killed Billy. It is later revealed that Spencer (King George) actually killed Billy to frame Ruby, and put David in the position of defending a killer rather than protecting the townspeople.
He appeared again in the episode "The Other Shoe", where flashbacks reveal that Rumplestikin transformed him into a human to escort Ella to the ball. He becomes distracted when a waiter walks by with a tray of cheese and Ella allows him to be excused and help himself to some cheese.
Jaq and Gus appear in the 2015 live-action movie, Cinderella, though they play a significantly smaller role than they did in the 1950 film. Additionally, Jaq, unlike the original film, is portrayed as a female, under the name Jacqueline, and is Gus' love interest. They also have two babies called Teddy and Matilda.
Kingdom Hearts: Birth by Sleep
Jaq appears in Kingdom Hearts Birth by Sleep for the PSP, and was one of the first new confirmed characters, while Gus is absent. He finds Ventus, shrunk down to 3 in (10 cm) by the Fairy Godmother, placed in a mousetrap, and helps free him, marking the beginning of their friendship. Ventus later helps him gather the necessary materials for Cinderella's dress, and despite a fight between Ventus and Lucifer, they succeed. Later on, while Cinderella is locked in her room by Lady Tremaine, Jaq attempts to get the key to her room up the stairs and is protected by Aqua when the Unversed ambush him. Jaq succeeds and the slipper fits Cinderella perfectly. I
Vocal for Gus
Gus' full name is Octavius, presumably after the Roman Emperor who was later known as Caesar Augustus, hence "Gus". Emperor Octavius was renamed Augustus when he became Caesar. In the French dub, he is named Gustav.
The theme park character versions of Jaq and Gus are gray, yet in the movies and other appearances, they are brown.
In Cinderella III: A Twist in Time, Gus does the Tarzan yell when he passes by Cinderella.
In the original film, Cinderella, and its sequels, Jaq is a male, and he is the best friend of Gus, to whom he shares a brotherly bond. However, in the live-action remake, Jaq's gender is swapped (so Jaq is a female in the live-action remake), and her name is Jacqueline, and she is Gus' love interest instead of best friend. This makes Jaq one of the few Disney male animated characters whose gender in the live action remake is swapped, followed by Kaa from The Jungle Book (who is a female in the live-action remake).
Jaq and Gus, along with the rest of the mice, affectionally refer to Cinderella as "Cinderelly".
