He is portrayed by Justice Smith, who later portrayed Tim Goodman in Pokémon: Detective Pikachu.
Growing up in Los Angeles, Franklin spent his childhood taking computers apart to see how they worked and turned that interest into a passion for coding and web design. He went on to graduate at the top of his class at MIT. Then Franklin worked at Jurassic World park as an IT technician monitoring the private network for glitches. He was initially stationed at an off-site tech complex in Irvine, California, but eventually got to go to Isla Nublar.
Some time after the Isla Nublar Incident 2015, Franklin joined the DPG because, despite being slightly afraid of dinosaurs, he believes they have the right to exist as any shark or spider does. Now he runs the DPG's social media and online marketing campaigns, making him a vital asset to expanding the group's reach around the world.
Jurassic World: Fallen Kingdom
Franklin goes back to Isla Nublar with Claire Dearing, Owen Grady, and Zia Rodriguez, in order to track, and eventually save, Blue. They are betrayed by Eli Mills, after having nearly drowned in a sinking gyrosphere, Franklin, alongside Claire and Owen, is forced to sneak onto the boat carrying the last of the dinosaurs off the island, and after having been left for dead. He helps hold down Blue while Zia removes the bullet from her hide and gives her a blood transfusion. Shortly thereafter, he is mistaken for a deckhand on the boat and is taken away from the group. Later, he helps Zia escape from the lab under Lockwood Manor by sedating Henry Wu. He tries to save the dinosaurs from dying of hydrogen cyanide poisoning, but the ventilation system is damaged beyond repair, leading to Maisie Lockwood releasing all of the dinosaurs trapped in the manor. Franklin and Zia travels to unknown destination.
Personality and traits
According to the actor Justice Smith, Franklin is a young, fragile, anxiety-ridden computer genius who's more comfortable in front of a computer screen than anywhere else. Smith also calls Franklin socially awkward in his friendship with Zia Rodriguez, who constantly picks on him for "being a wuss" and Franklin fails to make a comeback at her no matter how much he tries. Franklin is prone to panic in dangerous situations, often screaming when in any sort of danger. Despite his fragility, he is a remarkably competent individual, even under pressure.
