• The chapter recounts Leon’s history:
  • In his previous life, he was an ordinary office worker named Li Ang who died while intervening in a stabbing.
  • He was reincarnated as an infant in the Marvel universe and recovered his past-life memories at age one.
  • He was adopted by Howard and Maria Stark, who died in a car accident shortly afterward.

• The chapter ends by revealing that Leon’s eighteenth birthday changed everything, presumably granting him the power he has now.

Character Development

• Leon: Evolves from a powerless reincarnated child into a cautious but determined protector. He uses foreknowledge to improve the world and safeguard Tony, but repeatedly confronts the limitations of being an ordinary person in a dangerous superhero universe. His newly acquired Kryptonian power represents a major turning point.

• Tony relies heavily on Leon’s ideas for new technologies, casually transforming Leon’s suggestions into revolutionary inventions.
• Leon remembers Tony’s irresponsible treatment of him as a child, but also recognizes that Tony genuinely raised and protected him after their parents’ deaths.
