Rainn Delacourt was an American dinosaur trafficker who was the head of a dinosaur smuggling ring. Delacourt was wanted by the CIA’s Dangerous Species Division for his smuggling activities. Delacourt tracked Blue to the Sierra Nevadas, where he was able to determine that she had a baby, Beta. Rainn Delacourt also had tracked Owen Grady and Claire Dearing to their cabin in the Sierras, discovering also that they had been keeping Maisie Lockwood secret.He made a deal through brokerages such as Soyona Santos to sell the juvenile and Maisie to Biosyn.
Rainn Delacourt made his presence known as he passively observed Owen after he had managed to wrangle a Parasaurolphus. Rainn then followed Owen to his cabin, organizing his team to simultaneously kidnap both Beta and Maisie. Rainn personally oversaw Beta’s abduction, waiting until Blue and Beta were otherwise distracted with bringing food back to their nest, before slamming Blue with his vehicle, causing the dinosaur to fall down a small cliff. This distraction allowed them to be able to net Beta.
Delacourt, drove off then, firing his shotgun at Owen to prevent him from interfering, as he met up with his co-conspirators who had already trapped Maisie. Meeting up with his co-conspirators, he would use his truck to block Maisie’s escape, tossing her bicycle into the river after she had been abducted.
Delacourt and his trafficking ring would then travel to Malta, where they would transfer Beta and Maisie to Biosyn Valley with the assistance of Soyona Santos. He would then broker a deal with Santos to transport Atrociraptors to Ridayah, Saudi Arabia. However, the exchange was interrupted by CIA Dangerous Species Division officers and a gunfight ensued. In the chaos, Delacourt ran into the Amber Clave Night market, pursued by Owen Grady.
While fleeing through the market, a juvenile Baryonyx attempted to break its chains of captivity and launched itself at the smuggler, although he was able to escape. However, in the commotion a mass breakout inside the market ensued and several large animals such as an Allosaurus and a Carnotaurus escaped. Delacourt would then fight with Owen in the dinosaur fighting ring, attempting to slash at him with a knife, although he was eventually overpowered and knocked to the ground.
Delacourt was then attacked by a juvenile Carnotaurus and a Lystrosaurus who each bit one of his arms. As he screamed in pain, Owen interrogated him as to Maisie’s whereabouts. In agonizing pain, Delacourt confessed he had handed both Maisie and Beta to Santos. Just then, the Juvenile Baryonyx broke free of it’s chains, and lunged forward, attacking and killing Rainn Delacourt.
Rainn Delacourt was portrayed by Scott Haze. As portrayed in the film, his personality is that of a greedy individual who would do anything for money, including dinosaur and human trafficking. A chapter in the Jurassic World Dominion junior novelization also directly expanded on Delacourt’s personality, showcasing him as willing to impersonate federal officers in order to poach dinosaurs, as well as willing to kill both dinosaurs and humans to obtain his goals.
