Mechanical Guardian

Craft a tale about a fully autonomous artificial intelligence system that becomes a high-tech superhero.

This prompt provides an opportunity to delve into themes of technology and morality. A mechanical entity void of human emotions or biological needs taking on the role of a superhero raises engaging questions. What makes it decide to protect humanity? How does it perceive justice? What happens when human imperfections challenge these computations? The concept challenges the traditional definition of a superhero and allows to explore a future where machines may hold the mantle of guardianship.
