Midori Hayashi, known as Mindy in the English adaptation, is a human child who appears as a supporting character in the 1980 anime series Astro Boy. She is a classmate and one of the first human friends that Astro Boy makes after he begins attending school. Ten years old, she is depicted with brown hair and brown eyes, and she usually wears her hair in high pigtails. Her clothing often incorporates the color green, a visual reference to the meaning of her Japanese name, which translates to green.

Midori is an outgoing and well-spoken girl with a confident and friendly demeanor. She is quick to welcome Astro Boy into her circle of friends and regularly takes the lead in class projects and group activities. Her personality is characterized by kindness, compassion, and a strong sense of responsibility. She can be methodical and organized, and she values harmony in her relationships with others. Her innate empathy drives her to look out for those around her, and she often acts as a source of emotional support for Astro Boy.

Along with two other human classmates, Theodore and Kenneth, she is among the first children to treat Astro Boy not as a robot but as a peer. She provides him with guidance and encouragement during difficult situations, helping him navigate the complexities of human emotions and social interactions. Her unwavering loyalty and gentle nature contribute to Astro Boy's understanding of kindness and compassion.

In terms of key relationships, Midori shares a close bond with Astro Boy, serving as both a trusted friend and a moral anchor. She also interacts regularly with her other classmates, often functioning as a unifying presence within their group. While her motivations are not deeply explored, she is driven by a desire to help others and to do what she considers right. She does not possess any superhuman abilities; her strengths lie in her intelligence, her organizational skills, and her emotional perceptiveness.

Over the course of the series, Midori remains a steady and supportive presence, though she does not undergo significant personal transformation. Her development is reflected in her growing understanding of the challenges Astro Boy faces and her continued willingness to stand by him.
