Cores

Cores are mechanical spheres that mostly appear near the end of Portal and Portal 2. They were developed by Aperture scientists specifically to regulate GLaDOS' merciless behavior, such as refraining her from flooding test chambers or other vital parts of Aperture Laboratories with Neurotoxin, and/or to control the entire facility.

Personality Cores
As the name implies, each Core has their own unique personality and behavior, which gets copied over the central core.

Morality Core


The Morality Core is one of the cores attached to GLaDOS in Portal. Unlike other cores, the Morality Core is mute.

Curiosity Core


The second core attached to GLaDOS is the Curiosity Core. It tends to constantly ask questions, ranging from its surroundings, to Chell, to where it is going.

Intelligence Core


GLaDOS' third core, The Intelligence Core, also known as the Logic Core, goes on about an odd recipe for a rather unique kind of cake,

Anger Core


The last core attached to GLaDOS is the Anger Core. It is also referred to as the Emotion Core. All it does is snarl and growl ferociously at Chell.

Central Core
The Central Core is hardwired into the maintain of Aperture Laboratories and given the power to control and regulate the entire facility. Such power includes overseeing the events that occur, creating and stockpiling test chambers, and so on. Unlike the personality cores, the central core does not have to retain a spherical shape, just uncorrupted.

Corrupted Cores
Due to technical difficulties over time, a core may be automatically labeled as a Corrupted Core and would be subject to being automatically disposed of. However, if the corrupted core is the central core, a substitute core must be present in a core receptacle to initiate a core transfer. Once a substitute core is found, both cores must agree or disagree to the core transfer procedure. If one agrees while the other disagrees, the transfer process cannot occur unless a stalemate resolution associate is present to press the stalemate resolution button, which will initiate the core transfer process once the associate has returned to the core transfer bay.

Space Core


The Space Core is one of three active, corrupted cores. It has an unhealthy obsession over Outer Space and contantly expresses its desires to go to space in a rapid manner of speaking.

Adventure Core
The second corrupted core, the Adventure Core (or as it calls itself, Rick) talks like a stereotypical American soldier.

Fact Core


The Fact Core is the third corrupted core. It constantly states several random, twisted and not entirely true "facts" related to history, the current situation, as well as apparent facts about how right and handsome it is.
