20,000 Leagues Under the Sea
After the Nautilus was constructed, the prisoners became its crew, with Nemo becoming the Captain, they established a base on the Island of Vulcania. For several months the Nautilus travelled throughout the oceans, attacking numerous ships. After one such encounter, three survivors arrived aboard the Nautilus, Professor Arronax, Conseil, and Ned Land. Nemo quickly invited Arronax to join him and reluctantly took Conseil and Ned as prisoners. He hoped to use Arronax as an emmissary in order to allow Nemo to share his secrets with the world.

The Nautilus continued it's travels across the oceans. Nemo got to know Arronax better, and showed him some of his past. Ned continued to irritate Nemo due to his constant attempts to escape.

Eventually the Nautilus returned to the Island of Vulcania, only to discover it to have been invaded by soldiers because Ned had secretly released several bottles containing the location of the Island. Nemo decided to prevent the soldiers from finding his secrets, and left the nautilus to destroy the base. The attempt was successful, but as Nemo re-entered the Nautilus, he was unexpectedly shot in the back. Nemo died shortly after, gaining one last glimpse of the ocean.
