Bird (Portal 2)

"Augh! BIRD! BIRD! KILL IT! IT'S EVIL!"

- GLaDOS

The bird, a crow based on the caw she makes, is a minor antagonist in Portal 2. To the AIs Wheatley and GLaDOS. The bird attacks Wheatley after he used her eggs to break a door, and kidnapped GLaDOS while she was a potato. At the end of the DLC Peer Review co-op stage, the bird is chased out and locked out of Aperture by P-Body and ATLAS. Her eggs are hatched by GLaDOS after this, with GLaDOS planning to raise them into little killing machines.
