|“||You know what's great about hitting rock bottom, Eddie? There's only one way to go, and that's UP!||„|
|“||Dream big dreams.||„|
|~ Buster's catchphrase.|
Buster Moon is an anthropomorphic koala, who is the owner of the Moon Theater, best friend of Eddie, the archenemy of Jimmy Crystal, and the main protagonist of Illumination's 7th feature film Sing and its sequel Sing 2.
Buster has gray fur with white patches on his mouth and chest, and inside his ears. He wears a blue suit and pants with a red bow tie and brown shoes.
In his Christmas-themed outfit, he wears a red version of his suit with a green and yellow striped bow tie.
He is extremely optimistic. Even when the odds are against him, he will stop at nothing to accomplish his goals. Buster also has a passionate love for show business, particularly theater. He is wholly supportive of all his performers, and uses his managerial skills to draw out their talent. However, Buster is also pushy and opportunistic, willing to lie to steal electricity and water for his theater, and lie to his contestants about the prize money.
When Buster was a child, he wanted to be the first koala astronaut, but this dream changed after his father took him to see the play Epiphany. Young Buster was so amazed by the play, and star Nana Noodleman's performance in particular, he developed a lifelong passion for theater. Thirty years later, Buster buys the theater that staged Epiphany, using money his supportive father saved from his car-washing business; he renames it the Moon Theater.
At start of Sing, the Moon Theater has fallen on hard times, with several shows flopping and Buster accruing considerable debt. As a final effort to restore is theater's popularity, he decides to organize a singing competition, despite the misgivings of his best friend, Eddie Noodleman. Buster scrapes together $1,000 to give the winner, but thanks to an incident involving his assistant Miss Crawly, the flyers are sent proclaiming a $100,000 prize, causing a stir in the city. Ultimately, six acts pass the audition, but after one is injured and a second disbands early, Buster allows Meena, a failed contestant turned stagehand, to join.
To convince Nana Noodleman to provide the remaining $99,000, Buster constructs a glass stage filled with water and bioluminescent squids for an elaborate rehearsal. Unfortunately, it is interrupted by three bear gangsters who were cheated out of money by the contestant Mike; they demand the money in the chest as payment. When Buster stalls, the bear leader smashes the chest with a baseball bat, revealing its contents were less than advertised. Everyone's combined weight combined with the force of the baseball bat causes the stage to crack, flooding the Moon Theater and leading to its collapse.
With the destruction of his beloved theater, Buster completely gives up. He spurns his contestants' encouragement and desire to perform, and resigns himself to a lifetime of car-washing. It is only when hearing Meena sing "Hallelujah" in the Moon Theater ruins that Buster's spirit is restored. He rallies his performers, and together they stage an open-air concert in the ruins. The result is so spectacular it redeems Buster in the eyes of Nana, who purchases the theater property and finances construction of the New Moon Theater. Buster holds a grand opening, which closes Sing.
Buster sets his sights on making his theater a bigger success so he and his friends head to the big city to make his dream reality.
|“||“This was it. The moment it all began. The moment an ordinary little guy fell in love with theater. Everything about it: the lights, the way the scenery moved, even the smell. He was only 6 years old, but his plans to become the first koala bear in space were suddenly... toast. Some folks may have said he grew up to be the greatest showman the city has ever seen. Some called him a visionary, a maverick. Sure some folks said he was as crazy as he was stubborn, but I say wonder and magic don't come easy, pal, and oh, there would never be any doubt. The name Buster Moon would go down in entertainment history. And I should know, because I am Buster-”||„|
