The Defective Turret is a character featured in Portal 2.
The Defective Turret has a different and unique look compared to the regular ones found throughout the game. It is very boisterous and talky, as well as completely self-aware, which is completely opposite of the normal turrets. It is first encountered in Chapter 5, where Chell has to replace it with a normal turret on a production line. This makes it so that all turret produced afterwards follow the model of the Defective Turret.
Nolan North voices the Defective Turret, as well as the Space Core, Adventure Core, and Factual Core in the same game.
