Do you see that thing that fell out of me? What is that? It's not the surprise... I've never seen it before.
The Morality Core is a personality core that appears in Portal, and Portal 2: Lab Rat. It is one of many cores that was attached to GLaDOS in order to regulate her behavior. It was programmed to prevent her from doing unethical deeds, acting as an artificial conscience. When Doug Rattmann first sees the Morality Core, he doubts its capability to restrain GLaDOS, saying "You can always ignore your conscience". He turns out to be correct, as despite the Morality Core being attached, GLaDOS floods Aperture with neurotoxin anyway.
At the end of Portal, it falls off of GLaDOS' body, possibly intentionally. GLaDOS repeatedly tells Chell not to touch it, but she disregards this advice and destroys it in an Emergency Intelligence Incinerator. When incinerated, it is then known by GLaDOS as the "Aperture Science Thing We Don't Know What It Does". With her conscience removed, GLaDOS is free to flood her chamber with neurotoxin. However, the Morality Core was apparently also necessary for keeping the Rocket Turret in her chamber deactivated. Chell uses this turret to destroy GLaDOS.
The Morality Core as seen in LEGO Dimensions.
- Unlike the other cores, the Morality Core appears to be unable to speak, or simply decides not to talk.
- The Morality Core makes a cameo appearance in LEGO Dimensions; Wyldstyle installs this core after disconnecting its opposite, the "Amorality Core", from GLaDOS in an attempt to make her more cooperative.
- The Morality Core has one dot on each side, and it is the first core to be incinerated. This pattern is seen on all cores from Portal
