Captain Nemo (in Latin Nobody) — also known as Prince Dakkar — is a fictional character invented by the French science fiction author Jules Verne (1828–1905). Nemo appears in two of Verne's novels, Twenty Thousand Leagues Under the Sea (1870) and The Mysterious Island (1874), and makes a cameo appearance in Verne's play Journey Through the Impossible (1882).
Nemo, one of the most famous antiheroes in fiction, is a mysterious figure. The son of an Indian Raja, he is a scientific genius who roams the depths of the sea in his submarine, the Nautilus, which was built on a deserted island. Nemo tries to project a stern, controlled confidence, but he is driven by a thirst for vengeance and a hatred of imperialism focused on the British Empire. He is also wracked by remorse over the deaths of his crew members and even by the deaths of enemy sailors.
