David's father psychically battled Amahl Farouk on the Astral Plane and defeated him. To protect his son from any possible threats that would arise in the future, David's father handed him over as an infant to Mr. Haller and Mrs. Haller. However, Farouk's lingering consciousness found David. Farouk rooted himself within the boy's mind, intending to take full possession of David's body and use his powers to exact revenge on the man who defeated him. 
Powers and abilities
- Telepathy: Charles is a very powerful telepath enabling him to read and manipulate the minds of others. He was able to enter the mind of Gabrielle Haller when they were both in a mental hospital, helping her to communicate and recover from her catatonic state. He was also able to scan the minds of Amahl Farouk's pet monkey and mute children who populated his palace to see that trapped within them were the minds of Morocco's former king and his subjects. During his time in the war, he was able to force an enemy soldier into committing suicide.
- Astral Manipulation: When Charles first met Amahl Farouk, he was introduced to the Astral Plane and was almost immediately able to create anything he could imagine. From a lush forest to an image of Gabrielle holding baby David. His power was so great that when Charles battled Farouk on the Astral Plane, he defeated him and drove him out of his body.
