The mother of Zach and his brother Gray allowed the two to take a trip to the dinosaur park Jurassic World, that their aunt Claire Dearing, was operations manager. They were supervised by Claire's personal assistant Zara, as Claire was too busy to spend time with her nephews. Their known actions while visiting include being spectators in the Mosasaurus Feeding Show and going on a Gyrosphere ride. However, the park's latest attraction, a genetic hybrid named the Indominus rex, escaped during their trip. She attacked Zach and his brother while they were still in their Gyrosphere, but did not kill them. Some point after this attack he and his brother went into the restricted area of Isla Nublar where they found the ruins of the Visitor Center.
At one point amidst the chaos, Zach and Gray made it to Main Street only for a mixed flock of Dimorphodon and Pteranodon that were freed from their enclosure to attack the humans in the area. During this assault, they witnessed a Pteranodon pick up Zara and fly off with her, which led to Zara falling into the Mosasaurus' containment tank and both her and the Pteranodon being consumed by the aforementioned reptile. When the Indominus rex appeared, Owen Grady protected them from the hybrid.
