- "Oh, that's Charles Spencer by the way. He's a great kid. Computer engineering degree, 3.6 GPA. Had a floor-level gig at Intel planned for the fall. But first he wanted to put a few miles on his soul before he parked it behind a desk. See the world, maybe be of service."
- ―Tony Stark
Spencer was raised by his mother Miriam, a member of the State Department. After getting a degree in computer engineering, he decided to spend his summer in Sokovia and help build sustainable housing for the poor.
Eventually, Spencer started working in the capital city of Novi Grad and witnessed the Avengers fight the rogue artificial intelligence Ultron, who used vibranium-based technology to lift a large section of the city skyward. During the conflict, Spencer was crushed to death by rubble from a collapsing building.
Spencer's death caused his mother to confront Tony Stark about the Avengers' actions without restrictions. This led Stark to agree with the Sokovia Accords as he came to believe the Avengers would be no better than villains if they did not exercise or have restraints.
