The Thunderhead is in almost everything, from computers to cameras to publicars. It can also experience a wide array of human emotions, including betrayal, which it feels for the first time at the discovery of the Land of Nod. It has also been shown to be very compassionate and thoughtful, as it almost single-handedly raised Greyson Tolliver by itself. The Thunderhead has been shown to view mankind as its child, it being a parent that takes care of it. Being with Greyson at that moment was the Thunderhead's most joyous moment. However, it was finally necessary that it possessed Jerico's body to feel what it was like to experience the world. During Cirrus's inception, The Thunderhead was required to make many millions of iterations to make a perfect AI. At the sinking of Endura (and most notably, the death of Scythe Anastasia), it 'screams', sounding every alarm in the world simultaneously, followed by sending a high-pitched piercing screech through every speaker in the world, concluded by marking everybody as an unsavory, except Greyson Tolliver.įor the control of its interstellar missions to send colonists to far space, the Thunderhead created a new AI similar to itself called Cirrus, Cirrus was not bound to rules like the Thunderhead and therefore did things like reviving people even after they are gleaned.

It mourns as humanity tears itself apart and is shown to be caring and loving, almost like a benevolent God. In Thunderhead, several of the pages between chapters include the Thunderhead's thoughts. The Thunderhead spoke to Scythe Anastasia after she had been rendered deadish as an apprentice. It contained all the information of 'the cloud', or the internet, but all within the 'mind' of the AI. The Thunderhead was created in the year 2042.
