Berry is the yandere to Bloo from Foster's Home for Imaginary Friends.
Berry is a 5 year old female imaginary friend with two completely different sides to her, her first side being the cutest, sweetest girl in the world, the other being an insane, love-addicted brat with razor-sharp teeth. Berry bares her hatred on Mac when it comes to him stealing his attention from her. The second she comes to Foster's, she falls deeply in love with Bloo. Though Bloo did not feel the same way being unable to remember her name and in some cases her existence. This however did not deter her, she instead stalked him and shower him with extremely impressive gifts. However when she discovered Mac, her more crazy side came out feeling that no one can have Bloo but her. She then proceeded to try and get rid of Mac, at first by removing him when he and Bloo were together and making sadistic threats when he is alone. But she eventually went to extremes such as trying to murder him by running him over with a train!
- Bloo can never remember her name, or her in particular. At the end of her first appearance, he couldn't recall who she was after she was attached to the rubber band ball.
- Usually when Berry speaks in a sentence, she replaces the word very with berry, a reference to Strawberry Shortcake (an 80's cartoon).
- When Berry was rolled down the hill, it was a spoof to Indiana Jones.
