Buster Moon is an anthropomorphic koala. He has gray fur with white fur inside of his ears. He wears a white button-down shirt with a red bow tie covered by a blue suit jacket. He also wears blue pants with a black belt and brown shoes.
Buster Moon is truly the optimist, Buster doesn't know when to quit, and believes in the concept that when you've hit rock-bottom, the only way left to go is up.
Buster has a sincere love for show biz, especially theater, after attending his first theatrical performance when he was only six years old and was inspired to one day own his own theater and make his career in show business as a successful theater producer. He loves his theater and won't give it up without a fight, not only because of his love for theater but because his father worked so hard and for so long to help Buster buy the theater in order to fulfill his son's dream, and Buster keeps the bucket his father used in his car-washing business to make that dream a reality as a cherished memento.
Even when all odds seem to be against him, Buster looks for a silver lining in every cloud, no matter how unlikely or ridiculous, gives it his all, but oftentimes his refusal to quit comes back to haunt him.
His determination to save his theater from being shut down drives Buster to do anything and everything to do so, such as going to extremes to avoid dealing with the bank, illegally siphoning power from a next-door business after his theater's electric bill shuts the power down, and stealing gallons of water from a water tower to set up a unique stage, lying to his contestants about the $100,000 prize money (which was supposed to be only $1,000), etc.
He is cheeky, opportunistic, and even a little pushy.
When everything goes wrong and literally comes crashing down, Buster finally breaks and gives up, is unresponsive to his singers' support and encouragement, and fully prepared to accept a fate of car-washing until he hears and is inspired by Meena's beautiful singing to take one last shot.
He rallies the troops, they throw together a workable open-air theater, and perform for free, each of his singers' pulling off spectacular performances that redeems Buster in the eyes of the public as well as Nana Noodleman, the theater actress who was partly responsible for inspiring Buster to love theater, that she buys back the theater property and restores it, allowing Buster to hold a grand re-opening and truly make his career as a successful theater producer.
