Heat O'Brien

Heat O'Brien is the person which the AI version of Heat was created.

Appearances

 * Digital Devil Saga: Avatar Tuner 2: Major Character

Personality
As hot-headed as his AI counterpart, he would often make angry outbursts at how she was being treated, and openly expressed his disgust of the manipulative behavior of his coworker Serph Sheffield. This caused Sera to regard him as a scary big brother, as she never saw the side of him that cared for her.

The AI Heat is based upon the hotheaded, angry side of Heat O'Brien that Sera regarded with fear. Like Heat O'Brien, the AI Heat comes to care for Sera deeply, though he is unsure exactly how he feels about her- reflecting Sera's own confusion of their relationship- and can only express himself with anger and force.

Digital Devil Saga: Avatar Tuner 2
Heat O'Brien is a graduate of Berkeley College as a gene therapy doctor, he joined the Karma Society's God Project and was placed in charge of Sera's physical condition. His little sister died of the Cuvier Syndrome, and he came to care for Sera as a replacement sister, giving her a black cat named Schröedinger as a present.

While Sera was being put through a painful experiment, Heat finally snapped and pulled a gun on Serph, ordering him to stop the experiment for Sera's wellbeing. However, he was shot in the back by Argilla, and died.
