Darla is the niece of Philip Sherman, a dentist. She is not necessarily evil but she has killed fish before by accident.
Gill and the other fish in Sherman's fish tank describe Darla as a fish killer and that Nemo is supposed to be her new pet fish. The last fish she received, Chuckles, was killed by her because she wouldn't stop shaking the bag Chuckles was in. In the scene where Darla is about to take Nemo from her uncle, Nemo plays dead, but Darla thinks he is just sleeping and starts shaking the bag. Gill then fires himself out of the tank and lands in her hair, causing her to drop Nemo and his bag bursts. After Gill catapults Nemo into the air, Darla tries to grab him, but he lands in a sink and is swallowed into a drain leading to a sewer. Darla then looks down the drain and screams "FISHY!", and then the drain squirts water in her face. It is unknown what happens to Darla afterwards.
