Anger Core



The Anger Core is a personality core that appears in Portal.

The Anger Core is quite literally a sphere of fury. It lacks the ability to speak, instead resorting to making animalistic roars, snarls, and growls. It is quite possible that the Anger Core, being the last of the Cores destroyed by Chell and whose destruction also destroys GLaDOS, is inspiring GLaDOS to kill Chell and making her nastier, more sarcastic, and more homicidal than she would be otherwise.

The Anger Core is voiced by.

Trivia

 * Ellen McLain, at her 'So You Broke My Heart and Killed Me' panel during Anime West 2011, revealed that she was originally asked to voice the Anger Core. It was later decided that Mike Patton, lead singer of the alternative metal band Faith No More, should voice the core, as McLain's voice "just couldn't sound mean enough" for the part.
 * The Anger Core's characteristic growls are reused in Left 4 Dead and it's sequel, Left 4 Dead 2.
 * In Portal 2, Aperture Science Bombs bear a striking resemblance to the Anger Core. The Bomb shares an "angry" animation with the Anger Core, making it possible that the Core was to make a reappearance in Portal 2 at some point during development.
 * A similar red-eyed personality core appears in the "Portal 2 - The Final Hours" digital ebook.
