1. Captain Nemo: A knowledgeable engineer, cool-headed, calm and witty. He is not a scientist who can't stand the wind and rain in his study and greenhouse, but a national aspiration who grew up in the fire of anti-colonialism struggle.

2. Professor Pierre Aronnax: erudite and calm.

Conseil: Professor Pierre Aronnax's servant is calm by nature and never makes a fuss. Always so calm and easy-going, never anxious to get angry-at least you can't see him anxious to get angry.

4. Nederland: He is a primitive man, a wild whaler with a bad temper.
