In 2013, Barry was living in France. After noticing that the pack dynamic of Velociraptor was more complex than thought, his friend Owen Grady recommended Barry to Vic Hoskins to work with the raptors.
Barry took part in stopping an escaped Indominus rex after she had escaped her enclosure and was rampaging throughout the island. At one point in the incident, he noticed that the raptors he and Owen trained were oddly communicating. Owen also notices and realizes that the Indominus rex was also made of Velociraptor DNA, giving it the ability to communicate and become the new Alpha. Once the raptors turned on the humans, Barry ran to a nearby log and was attacked by Blue and was nearly killed by her until Owen whistled for her and she turned to chase him instead, saving Barry's life. He would later evacuate to a hanger in Costa Rica with the rest of the evacuated tourists. 
Personality and traits
Barry is bilingual, knowing both French and English.
Barry owned a Remington 870 fitted with a Crimson Trace Rail Master (CMR-201) laser sight, Mossberg ghost ring sights, and a Magpul MOE furniture and a 4" Smith and Wesson model 500 revolver as his sidearm. He is notably seen pulling it right before an encounter with Blue, the Velociraptor. The revolver is noted as such by its big bore and enormous cylinder, At times, the revolver is loaded with JHP rounds.
Barry was known to have had a friendship with Owen Grady even before working together with the raptors.Owen was able to converse with Barry even when the latter spoke in French, despite the former never demonstrating the same ability.
Barry appears to tolerate Vic Hoskins and respect his position as head of park security(as well as the fact that he writes out his paycheck) but thought that his ideas of using raptors as weapons used in war as a foolishly stupid idea which he laughs off at initially but once he starts seeing that Vic is turning his own plan into a reality Barry approaches the situation with caution.
Blue is shown to viciously attack Barry as she corners him into a log. Barry draws his pistol in defense but can't muster up the courage to shoot Blue so instead he calls out her name, which makes her briefly stop and stare at Barry but then she continues clawing the log until she gets distracted by Owen. This scene shows that Blue had some kind of relationship to Barry that almost mimics Owen although it is clear that she doesn't respect him as much as Owen either.
Barry is shown to understand the behavior of Delta well and tells Vic Hoskins that she gets hungry whenever she looks at him or he pets her. It's possible that Barry and Delta see each other in a similar way that Owen and Blue see each other.
Barry provides the player missions in Jurassic World: The Game and requests materials to increase raptor obedience in the Raptor Paddock.
Barry appears as a playable character in LEGO Jurassic World.
Behind the scenes
Barry's first name was first revealed in the LEGO Jurassic World toy line, while his last name was later revealed in the Jurassic World: Evolution video game. Neither names are ever actually spoken in the film, making him the first major character in the film franchise to have both their first and last names revealed by licensed merchandise. Oddly, Barry does not have his own character profile on the LEGO Jurassic World website despite appearing in the toy line.
