Danny Nedermeyer is the nephew of Dennis Nedry and is the main antagonist of LEGO Jurassic World: The Secret Exhibit and the series, LEGO Jurassic World: Legend of Isla Nublar and plans to destroy Jurassic World to avenge his uncle. He was voiced by Adrian Petriw. He also appears in the Mini-Comics as a secret antagonist, trying to smuggle dinosaur bones out of the island to get money to destroy Jurassic World, and make his own park.
- Danny Nedermeyer is the fourth human villain in the franchise (After Lewis Dodgson, Billy Yoder, & Eli Mills). who tried to kill another human with his bare hands. However, unlike Dodgson and Mills, neither Danny nor Yoder was successful.
- Danny Nedermyer is somewhat of a parody of his uncle Dennis Nedry. Mainly in taking Nedry's comedic personality & computer expertise to absurd levels in addition to Danny's apparent "troll" personality.
- Danny bears a strong resemblance to his uncle minus the freckles and weight (although this could be unclear due to his LEGO based design).
