Dr. Gustavus is a geneticist who works for InGen.
Introduction[]
Dr. Gustavus is accredited as one of the top geneticists in the world. InGen had allegedly paid top dollar to get his employment at Jurassic Park, even going so far as to fire employees who disrupt his work (something that his coworkers are well aware of and thus allow him to do what he pleases, regardless of it being company protocol).
Return To Jurassic Park[]
Meanwhile to the events of the film, InGen scientists, Derrick Hoyle and Abby Nakajima, stumble upon the scientist, as he’s secretly loading away on fertilized eggs off somewhere. When asked about this by Derrick, Gustavus quickly retaliates by threatening the man’s job before driving off. Abby and Derrick would trail him back to a private cliffside laboratory. In which they find a stack of small privately cloned dinosaurs, that Gustavus had been creating behind Hammond’s back, including a small Triceratops, Avimimus, and a Leaellynasaura named Gideon with almost primate level intelligence.
Gustavus would attempt to kill the two scientists by holding them at gunpoint and cover up their deaths as an accident regarding the carnivores. Before he attempted to shoot them, however, Gustavus reveals that he took the job at Jurassic Park in order to genetically clone dinosaurs to create a superior race to humans. This, however, is quickly retorted by Abby and Derrick who manage to escape.
By the end of the story, and after a brief encounter with an adult Dilophosaurus, Gustavus is nearly killed by the dinosaur before he attempts to kill the scientists, now badly scarred, and with a slurred speech, now with his machine gun, he and Abby both tried to convince Gideon to hand a pistol over to them. When Gideon began handing the gun to Abby, Gustavus angrily shouted at the dinosaur, causing the startled Gideon to press the trigger and shoot Gustavus in the chest, killing the dinosaur's creator. However, the stormy weather caused the cliff holding up the lab to break and, while Derrick and Abby managed to escape, Gustavus, Gideon and all of the other genetically enhanced dinosaurs fell into the sea with the lab, where they drowned.
