Although, he is perfectly capable of fighting with his bare hands, even delivering a single knock-out punch to the stomach at one point. Besides being an expert in surgeries, he is also a skilled combat fighter who makes use of his surgical tools (notably the scalpel) that he hides underneath his cape. In difficult and tricky situations, he is a quick thinker and is able to fool others easily (mostly with good intentions). Throughout his life, Black Jack learned some harsh lessons and has to face the reality that there are times he cannot go against the forces of nature. Since Pinoko came into his life, he cares for her deeply as if she were his daughter and he gives her lots of (tough) love.

Those who witness how he operates sometimes comment that his work is divine. He is very perceptive and able to diagnose a patient with only one look. Although he charges absurd amounts of money for his procedures, he performs free surgeries on people who touched him with their kindness or struggles in life. Many people assume that Black Jack is a rude and soulless person because of his appearance and first impressions, but in reality he is a very compassionate and dedicated person. He lives in the richest house on an island off the coast of Osaka, Japan with his adoptive daughter Pinoko and his pet dog, Largo. Kuroo has adopted a young conjoined twin girl named Pinoko and his pet dog, Largo, who were also adopted by him. As he grows older, he continues to grieve her death.

The young boy is present when his mother, Mio, dies in a beachside explosion, and he mourns alongside her. Honma, Kumiko's father, works with him in their rescue operation. Black Jack was taken to the hospital and later, Kuroo was taken to the emergency room while his mother, Mio, was taken to the operating room. Kuroo found the giant bomb and his mother, Mio, was scared and screamed. One day, there was a bomb left in the sand floor by The Evil Gang. When Kuroo was a baby, he and his mother played ball on the beach.
