Biography[]
Very little is known about Captain Nemo's history. Only that he was once a "civilized" and "rich" man. Then for some unknown reason, he left society and built the Nautilus. It's assumed that he saw all the cruelty and injustice in society (slavery, corruption, imperialism and etc.) as a crime against the world.
Once the Nautilus was built, Nemo cuts of any ends to the human world. He mostly uses resources from the sea (food, clothing, furnishing and most supplies comes from ocean). However, most of his research are based on Professor Aronnax writings and his music are from some of the greatest composers in the world. He sinks ships to get his revenge on the world, under the philosophy that they are part of "the dealers in death".
When Professor Aronnax, his assistant Consiel, and master harpooner Ned Land were captured by Nemo and his crew, the Captain treats them as guests/prisoners, say that the are free to go wherever they want on the Nautilus, but not leave the Nautilus, ever.
The Captain shows the professor around the Nautilus and teaching him the treasures of the ocean. They travel with the Nautilus around the whole world. From underwater forests to the Lost City of Atlantis.
However, the Nautilus was eventually attacked by a ship from the imperialist nation that had caused Nemo so much pain. Enraged, Nemo used his submarine to breach the ship below the waterline, killing all onboard. Horrified, Aronnax and Land decided to escape. During their escape, the Nautilus sailed into a whirlpool, implicitly on the orders of Nemo in order to commit suicide. Aronnax and Land escaped, leaving the captain's ultimate fate unknown.
