According to then-studio head of the Coalition Rod Fergusson, the ideas of setting the fourth main series game in the future and for
Marcus to have a son named JD were originally conceived at Epic Games prior to the Microsoft's acquisition of the intellectual property. Fergusson made the decision to set
Gears of War 4 25 years after
Gears of War 3, paired with a "fresh visual aesthetic" to match its new story which feature a vibrant and youthful cast. In a 2019 interview with
VentureBeat, Fergusson further elaborated that this helped give the developers "a lot of head room" in terms of where the younger cast of characters as they could be changed and transformed over time, and referred to JD's
character arc in
Gears 5 as an example. In writing for new characters, Franchise Narrative Director Bonnie Jean Mah stated that these new characters, with or without their connections and trappings to the
Gears of War universe, need to be interesting and believable in their own way as part of their guiding principle. Within the game universe, JD is the son of Marcus Fenix and Anya Stroud. He is named after Marcus' deceased best friend, Dominic Santiago. He is described as "an idealist who wants to live his life with purpose", and the character's backstory involve him running away from home as a youth and enlisting with the armed forces of the Coalition of Ordered Governments, leading to a rift between him and his father who disapproves of his actions. JD eventually attains the rank of lieutenant before going
AWOL with his best friend Delmont "Del" Walker due to a classified incident involving the deaths of innocent civilians by COG security forces, and seeks refuge within an Outsider village led by Reyna Diaz, who oppose the autocratic rule of the COG government. JD's distinguishing features include blond hair, blue-grey eyes, a slight unshaven stubble, as well as a previously broken nose which The Coalition intended to "give him more character". Unlike his father, JD is written as a goofier and more lighthearted character, who regularly makes
quippy remarks instead of growling in a dour manner. For the character models of JD and his friends, the team attempted to redesign the human characters of the
Gears of War franchise with more realistic body proportions. The team experimented with taking personal effects off a character model's waists or legs to reduce their overall mass. They concluded that it "looked odd" as there is already an established set of subjective expectations for the franchise's characters, particularly with the way they would move around in the in-game environment or take cover. According to creative director Chuck Osieja, the team resolved to find a middle ground between the "giant moon boots and big blocky characters" of the original games, and realistic and believable sensibilities while retaining the "power and strength" that
Gears characters. The Coalition intended for JD's character design to be recognizable when portrayed by a cosplayer at a fan convention. Visually, JD's look undergoes a number of changes between
Gears of War 4 and
Gears 5. In the former, JD is a former COG soldier trapped between two divergent worlds and is trying to adapt to the Outsiders' lifestyle. To reflect and convey the concept of duality in JD's visual design, his style of dress integrates COG tech with the Outsiders' signature reclaimed clothing to help visually differentiate him. JD is not shown to be wearing any armor when his first appears as a member of the Outsiders; instead, he combines a reclaimed leather jacket with typical COG-styled accessories like a holster, backpack and military boots. To reflect the introduction of hazardous weather elements into the gameplay of
Gears of War 4, concept artists explored putting a hood and googles on JD's face to show protection from strong winds, but settled on a subtler approach via a faded army green scarf as an accessory instead of obscuring his face. JD's final look, following his reunion with Marcus, has him wearing khaki work pants and a rolled-sleeve sweatshirt under his protective chest plate. JD's look and personality in
Gears 5 undergoes a dramatic change following an incident at the conclusion of the game's first act, which is intended to reflect his intense combat experiences since
Gears of War 4. Besides a shaved head and grown out beard, he also has a severe scar on his face, and wears a medical device for pain management of his still-healing arm which glows blue when activated. Like the game's other main characters, JD undergoes costume changes to match the environments they visit.
Portrayal JD's voice actor, Liam McIntyre, described his character as "very different to his father in the sense that he gets to be the new young kid on the block. He's sort of the
millennial of the story." McIntyre noted that JD brings a fresh perspective into the series, noting that "he sees his tough grump of father but he's the young hopeful one", and describe JD's attempts to reconcile with his father as yielding potential for a "wonderful kind of conflict". As JD is born after the war with the Locust Horde and had not gone through any of the hardship his father had experienced, he thinks that he is making the world a better place and that he does not want to emulate his father. McIntyre said the events of
Gears of War 4 is a formative experience for the character as he starts to encounter some of the terrible things his father once saw, and his personality would evolve from these experiences. McIntyre acknowledged that he is a lifelong fan of video games, and that he was excited to secure the role of JD Fenix, his first video game character role. He admitted to have experienced pressure about playing the son of an iconic video game character as he wanted to live up to the expectations of "hardcore fans of the franchise". On the differences between portraying a video game character as opposed to working in television or film, McIntyre explained in an interview that he is more likely to be working in an actual set which replicates the setting, which is something he had taken for granted; whereas for a video game character role, he would be reliant on extensive instructions to visualize a given scene respond to the circumstances the player character find themselves in, and that he spends a lot of energy vocalizing to his best ability. McIntyre opined that other actors in the industry have begun to form the view that "uniquely amazing stories" could be told through the video game medium due to its interactive nature, and that while he portrays JD Fenix, the player also has agency in the character's actions and is not a passive observer. ==Appearances==
