The Original Astro Boy

Somewhere in the future, Dr. Boynton creates a robotic replica of his deceased son Astor. When the replica is far too robotic and emotionless, Boynton rejects the robot and plans to wipe his memory and sell him off. Astor begins to develop his own personality after getting into fights against other robots, and rebels. A now terrified Boynton implants a robotic bomb spider named Bruno into Astor, and sells him to Cacciatore's Robot Circus under the name "Astro Boy." (Source: Wiki Fandom)
