Accompanied by Antelle and Ulysse Mérou, he travelled aboard a spaceship to the star Betelgeuse.
The Woman Edit
After arriving on the planet Soror, Arthur was the one who spotted the naked Nova, nearly scaring her off by his enthusiasm at her femininity.
When Nova had murdered Hector, Ulysse had referred her as a savage, Arthur rebuked him asking how such a graceful creature like the young woman could ever be compared to come from a primitive tribe.
Both he and Ulysse were the ones who supported the idea of remaining in the jungle and making contact with the savage humans rather relocating their launch to a more civilize location. The two men silently shared the desire to see the naked savage again, despite the risks.
After returning to the lake where they met the girl, Levain suggested that they remove their clothes as they seem to frightened her. His theory proved correct, as Nova appeared along with a group of similarly undressed men and woman from her tribe.
Like the others he was stripped of his clothing and dragged into the depths of the jungle by Nova's tribe. While interacting with Nova, Levain was envious of Nova's affection toward Ulysse as she helped his companion build a nest and spent the night with him. When the apes hunters came and raided Nova's tribe, both he and Ulysse fled leaving Professor Antelle behind.
Levain lost his nerve in his first encounter with the apes on the planet Soror and was shot and killed quickly by the hunter's guns, but his death allowed Mérou a chance to escape. He was last seen among-st the rows of game that had been shot during the hunt, with a female ape striking a pose, sitting on his corpse for a chimp photographer.
- The French word 'physicien', from the source novel, was mis-translated into English as 'physician' by Xan Fielding; the word actually means 'physicist'. Other-language versions correctly translate as 'physicist'.
- Levain's personality is closest to that of Landon in the movie adaptation, Planet of the Apes, but it is Dodge who is shot and killed in his first encounter with the apes, and Taylor discovers him as a stuffed and mounted display in the ape museum shortly afterwards. Levain, like Dodge, is also shot and killed during the hunt, but the last we see of him is a female gorilla standing over his dead body with a photo being taken by a chimp photographer.
