Sonya is one of the protagonists of Madagascar 3: Europe's Most Wanted.
Sonya is a female black bear with brown eyes. She wears a pink tutu, has a bow in her hair, and rides on a tricycle. Strangely, she is very close to a non-anthropomorphic animal, meaning that she does not really talk in English, but instead communicates by growling and roaring, just like a real-life bear would do. However, she somewhat might have intelligence, as she understands other characters. During the film, she breaks her tricycle which is replaced by a Ducati motorcycle. Soon she starts a relationship with Julien, who is smitten with her. She enjoys riding her bike and becomes upset if it is ruined.
When King Julien, Maurice, and Mort are on the train, they get scared by all the torn-up stuff. Soon, they see red eyes and become more frightened. The eyes are revealed to be Sonya's, whom Julien instantly falls in love with. He woos her with a fish before she eats Julien whole and pulls him out, all covered in spit and puts him on her back. He compliments Sonya, but she just puts up with him.
She and Julien go on a tour of Rome, where he gives her the Pope's ring after secretly stealing it. Soon, Sonya breaks her tricycle, but Julien replaces it with a motorcycle (which he pays for using the Pope's ring). They make it back to the circus just in time to run away from the angry mob.
When Alex says they need to change up the acts, she cheers by roaring. During the circus act, she and Julien perform stunts on her motorcycle. Soon, Alex and the gang decide to go back to the zoo. Julien decides to go with them, leaving behind a heartbroken Sonya.
When the animals get to the zoo, they're ambushed and darted. King Julien manages to go back to the circus and tells Sonya that he doesn't want to be king anymore and would rather be with her and she happily takes him back. During the "Afro-Circus" scene, she and Julien are dancing together.
