Hector was a primitive chimpanzee taken with astronauts Professor Antelle, Ulysse Mérou and Arthur Levain on their spacecraft, journeying with them to the planet Soror. On landing on the planet, Hector scampered towards the nearby forest but was suddenly strangled to death by Nova, who had an instinctive fear of apes.
Trivia
- As the doomed fourth passenger of the spacecraft, Hector is in one sense similar to Stewart from the movie adaptation, Planet of the Apes, but Stewart died during the ship's voyage.
