Jimmy Crystal, commonly known as Mr. Crystal, or more shortly by his surname Crystal, is the main antagonist of Illumination's 11th animated feature film Sing 2, the second installment of the Sing franchise. He is an Arctic wolf who is the head of Crystal Entertainment, the estranged father of Porsha Crystal, the boss of Jerry and Suki Lane, and the arch-nemesis of Buster Moon. Crystal holds auditions for musical shows at his theatre, but it later turns out that if anyone he hires does not give him what he wants or misleads him, he is more than willing to make them pay for disobeying him, to the point of even trying to kill them, including Buster Moon and his friends.
