In The Angel Experiment by James Patterson, the character is often described as having a robotic or mechanical quality. He sometimes appears almost like a droid or a drone, highlighting his emotionless or highly controlled demeanor. This comparison emphasizes his unique personality traits and possibly his communication style or behavior patterns.

The references to "Fang of Nine" and "Fang2-D2" suggest a connection to popular robotic characters from science fiction, further illustrating the character's appearance or nature. Overall, these descriptions paint a picture of someone who seems more like a machine than a typical human, underlining themes of humanity and technology in the story.
