The Angel

For the main article, see Atlas.
The Angel (天使) is the given name to Atlas by Chevelle Fordyce in season two of Finding the Garden of Eden.

Background
The Angel was the first prototype of androids or synths that had the alleged intent to become AI police officers. While Eros and Helios' intentions meant to become that of law enforcement is plausible, Atlas's original plan had an entirely different meaning. The Angel was at first designed to be "the beginning and the end" of androids of his kind, until he started to have ideation of becoming a superior kind to the human race. It was then the idea was scrapped, his hidden ability almost entirely disabled, and he was used as a test subject for the AI police officer programs until further prototype improvements were made.

Season two
After Chevelle was born, the immediate death of his mother, and abandoned by his father Alex Fordyce in 2255, Atlas was given the task to hand the infant off to an NCR base in New California. With suspicion that Alex's former friend Travis Navarre would not take care of Chevelle, Atlas served as a hidden protector throughout his life. When Chevelle was old enough to take notice of this, he began doodling Atlas over and over again, claiming that he wanted to "get it right" as Atlas seemed slightly different in every picture. Eventually Atlas is depicted as a gawky figure with protrusions from his back, which are later discovered to be wings. Chevelle refers to Atlas as "the Angel" until Atlas formally introduces himself in 2281.

The Angel is drawn with wings, which was a rare and powerful hidden ability of Atlas, which had only happened twice: once when Chevelle witnessed it as a child, and again in his final attempt to protect Chevelle against Alex which ends up being fatal. Chevelle then retrieves Tenacious II, and later on murders his father alongside Gideon.
