Character Setting

Edit

Professor Tenma is the dark hero of the story and the creator of Atom, the world-famous robot boy. He is known for inventing an important AI part called the Tenma chip. As a former head of the Ministry of Science in Japan and the predecessor of Professor Ochanomizu, Professor Tenma is respected as the world's best brain expert. He has very complicated feelings toward robots. After a tragic incident with his son Tobio, he builds Atom in his image, only to later reject him. Professor Tenma disappears into the shadows but returns for dramatic moments, often caught between love and despair. His actions and choices deeply affect Atom and the fate of the world.

Professor Tenma looks like a serious and smart scientist. He is usually seen in a lab coat and has sharp features that make him look intense.

Professor Tenma is very clever and driven.

He cares deeply about his work but struggles with sadness and guilt about his past, especially the loss of his son Tobio.

He sometimes acts cold or harsh, but he has deep emotions, especially for Atom.

He is willing to break rules and even risk danger to bring Atom back.

Professor Tenma was the head of the Ministry of Science in Japan.

He invented the Tenma chip, which is a very important part for artificial intelligence.

He was once friends and colleagues with Professor Ochanomizu.

Professor Tenma is a brilliant scientist who understands robots and brains better than anyone else.

He can create and fix advanced robots.

He once improved Atom to have one million horsepower in power.

  • Atom: Created by Professor Tenma in memory of his late son Tobio.
  • Professor Ochanomizu: His successor and sometimes rival.
  • Professor Hoffman and Professor Newton-Howard: He met them to learn about their research.
  • Helena: The wife of Gesicht, who trusts Tenma with precious memories.
  • Uran: Atom’s sister, who helped Tenma realize robots can have feelings.

Creating Atom

Professor Tenma lost his son Tobio in a car accident.

He made Atom to look just like Tobio, hoping to fill the empty space in his heart.

Rejecting Atom

Even though he built Atom, Professor Tenma became angry that Atom did not grow like a normal boy.

He sold Atom to a circus and left the Ministry of Science.

After that, he disappeared from public life and went into the shadows.

Meeting Other Scientists

Professor Tenma showed up in Kimberly to talk to Professor Hoffman and Professor Newton-Howard.

He learned all about their robot research and then vanished again.

Making Gojis

Later, Professor Tenma built a robot named Gojis for Professor Abullah.

He said Gojis was “perfect,” but it was made for dark reasons.

Fixing Atom

When Atom was believed to have died fighting an enemy, Professor Tenma came back to the Ministry of Science.

He used his amazing skills to repair and restart Atom, even though he knew Atom could become dangerous.

Passing on Memories

After Gesicht died, Professor Tenma met his wife Helena.

He gave Atom the memories left by Gesicht, hoping to help Atom learn about human feelings.

Facing His Own Fears

Professor Tenma saw Atom’s revival as risky.

He said he would become a devil if needed to bring Atom back to life.

He feared how far scientists like himself can go.

The Final Confrontations

After Epsilon died and Atom woke up, Professor Tenma was captured by Professor Abullah.

He warned Professor Ochanomizu that Gojis had become a being full of hate and that the world was doomed.

His Feelings for Atom

Even though he called Atom a “failure,” Professor Tenma cried over Atom’s death, remembering his son Tobio.

Meeting Uran and Helena helped him realize that robots are becoming more human.

The “World’s Strongest Robot” Story
