He was the son of Peter Solomon, a Freemason. After his father persuaded him to join the Masons, Zachary rebelled and ran away. He left, started abusing cocaine and was eventually imprisoned in Turkey. During his incarceration, he overheard a phone call from his father to the warden, who said he would not take his son out with bribery, although he could. Angered, Zachary had an inmate killed, and they reported Zachary dead. Zachary broke out under the name Andros Dareios.
After prison, Andros Dareios fled to Greece. In Greece, Andros started reading and doing steroids. He even tattooed himself to hide his scars. But after years of paradise, he felt empty. He then saw on TV something about the Masonic Pyramid. So he decided to hunt down his father to achieve it.
The Death of Isabel SolomonEdit
On Christmas, Andros entered Peter's home, masked, and asked his father for the pyramid. Peter said he didn't know what he was talking about. Angered, Andros shot and killed his own grandmother. Peter chased him down, and he was presumed dead when he fell in the freezing river. But Andros, now Mal'akh (the Hebrew word for angel), was alive and wanted revenge.
A few years later, Mal'akh hunted and found Professor Robert Langdon and asked him to come to Washington D.C., telling him it was his father's request. He had already kidnapped Peter and cut off his hand. And simultaneously was trying to kill his aunt Katherine Solomon and all of her research.
But Professor Langdon, with the aid of Katherine Solomon along with the CIA director Inoue Sato and Architect Warren Bellamy, eventually thwarted Mal'akh's plans. But Mal'akh, having already kidnapped his father, commanded Peter to kill him. And then gave him the truth: he was Peter's presumed dead son.
Zachary "Mal'akh" Solomon was killed when helicopters came and sprayed glass to the floor. Later, his soul was was suck by the evil entities who were presents in the sacrifice chamber.
