The characters of the Gears of War franchise appear in a series of military science fiction video games created by Epic Games and subsequently developed by The Coalition, as well as associated novels and comics. Set on the planet Sera, the games follow soldiers of the Coalition of Ordered Governments (COG), civilians caught in its wars, and their adversaries. The original trilogy centers on Marcus Fenix and the other members of Delta Squad as humanity fights the subterranean Locust Horde and the mutated Lambent. Gears of War 4 introduces a younger generation, including Kait Diaz, Del Walker and Marcus's son JD Fenix, while exploring the aftermath of the Locust War and the continuing conflicts affecting humanity. Kait becomes the principal protagonist of Gears 5 as the COG prepare to confront the resurgent Locust, now reconstituted as the Swarm. The prequel Gears of War: E-Day returns to Marcus and his best friend Dominic Santiago as young men at the beginning of the Locust War.

This list includes major recurring characters and significant supporting characters that appear throughout the main series and selected spin-off titles. The cast combines returning protagonists with supporting characters introduced in individual games and spin-offs. Character development has included changes to the original squad's designs and backgrounds, the expansion of relationships through tie-in fiction, and a shift toward protagonists raised after the Locust War.

Critics have discussed the soldiers' comradeship, bereavement and relationship with military authority, while disagreeing over the effectiveness of the dialogue and the depiction of women and racial minorities. Later commentary has examined Kait's perspective on the COG and the consequences of its actions.

Creation and development Epic gave human soldiers and Locust similar proportions so that they could share animation systems. According to lead level designer Jim Brown, several members of the original cast changed during production. Baird initially had the professional athlete background later assigned to Cole, with David Beckham informing his appearance; Cole drew inspiration from Jamie Foxx's character in Any Given Sunday. Marcus's model and voice also changed between the game's announcement and release. The team considered allowing players to choose between a male Dom and a female counterpart, Dominique. Brown said that RAAM was added relatively late, leaving limited time to explain the final confrontation aboard a train.

Cliff Bleszinski wanted to give Dom's search for Maria greater prominence in the first game, but attributed its limited treatment to time constraints and Epic's lack of confidence in its storytelling. The relationship became a central subplot of Gears of War 2, providing an emotional counterpoint to the violence. Discussing the sequel's female characters, Bleszinski described Anya as strong-willed and maternal, and said that the team had avoided designing her around sexual appeal.

Karen Traviss, who wrote the early Gears of War novels and the script for Gears of War 3, worked on the books and game in parallel. She described the task as finding convincing responses for established characters within an existing story framework. The collapse of the COG in the third game removed the soldiers' institutional structure, making their squad an increasingly important substitute for family. Traviss understood Marcus's actions principally through his desire to protect individual people, rather than an ambition to become a hero. His discovery that Adam was alive offered another chance to save his father while complicating his earlier grief and guilt.

Gears of War: Judgment shifted attention to Baird and Cole earlier in their military careers, alongside the new squad members Sofia Hendrik and Garron Paduk. Their backgrounds placed a military cadet and a former enemy soldier within the same unit. For Gears of War 4, The Coalition introduced JD, Kait and Del as the central trio. Laura Bailey described Kait's unfamiliarity with COG technology as a way for new players to encounter the setting through her. Eugene Byrd said that his friendship with Liam McIntyre helped their performances as Del and JD.

Studio head Rod Fergusson described Kait's leading role in Gears 5 as a continuation of the previous game's story. Comparing Gears of War 4 to Mad Max: Fury Road, he likened JD to Max and Kait to Furiosa: the playable lead accompanied another character whose personal story drove the journey. Making Kait the next game's protagonist followed from that distinction.

For Gears of War: E-Day, The Coalition returned to younger versions of Marcus and Dom, presenting their relationship before the events of the first game. Creative director Matt Searcy emphasized shared burdens, trust and loyalty, while brand director Nicole Fawcette described the pair as more vulnerable than their later incarnations. The developers also redesigned the Locust Drone to make an individual encounter threatening to characters experiencing the invasion for the first time.

Coalition of Ordered Governments Soldiers and support characters The COG's recurring military characters include members of Delta Squad, whose central soldiers in the first three games are Marcus Fenix, Dominic Santiago, Augustus Cole and Damon Baird, with Anya Stroud initially providing communications support. JD Fenix, Kait Diaz and Del Walker form a later incarnation of the squad. Gears Tactics, a prequel spin-off, follows Gabe Diaz as he and Alpha Squad pursue the Locust scientist Ukkon.

Marcus Fenix

Marcus Fenix, voiced by John DiMaggio, is the principal playable character of the original trilogy. A veteran COG soldier, he is imprisoned after abandoning his post to try to save his father, Adam. Dom frees him during a Locust attack at the beginning of Gears of War, and Marcus returns to service, taking command of Delta Squad after the death of Minh Young Kim. His leadership brings him into conflict with military authority, while his closest relationships are with his squad and surviving family.

Marcus leads the missions against the Locust in Gears of War 2 and searches for Adam in Gears of War 3. The latter ends with the deaths of Dom and Adam and Marcus's killing of Queen Myrrah. After the war, Marcus marries Anya and becomes JD's father. In Gears of War 4, he is a widower living in retirement when JD and his companions seek his help against the Swarm. He subsequently fights alongside the younger generation, although his relationship with JD is strained.

A younger Marcus is the protagonist of Gears of War: E-Day, a prequel set fourteen years before the first game.

Dominic Santiago Dominic "Dom" Santiago, voiced by Carlos Ferro, is Marcus's closest friend and the second player's character in the first two games. He secures Marcus's release from prison and remains his principal companion throughout the original trilogy. Alongside his military duties, Dom searches for his wife, Maria, who disappeared after the deaths of their children. His contacts among the Stranded, civilians living outside COG protection, help the squad obtain assistance.

In Gears of War 2, Dom discovers Maria in Locust captivity, severely injured and unable to respond to him, and kills her to end her suffering. He remains distressed by her death in Gears of War 3. When the squad is trapped by enemy forces, he sacrifices himself by driving a fuel tanker into their position, allowing the others to escape.

Gears of War: E-Day returns to Dom and Marcus's relationship as veterans of the Pendulum Wars facing the first Locust invasion.

Augustus Cole

Augustus "Cole Train" Cole, voiced by Lester Speight, is a former star of thrashball, a fictional contact sport. His enthusiasm and theatrical manner contrast with the other soldiers' more restrained or cynical personalities. He joins Marcus and Dom after his original squad suffers heavy casualties in Gears of War, and frequently serves alongside Baird. Gears of War 3 makes Cole playable during a return to his ruined hometown, including the stadium where he played before the war. Gears of War: Judgment depicts his earlier service under Baird in Kilo Squad. He returns as a veteran assisting the protagonists in Gears of War 4 and Gears 5.

Damon Baird

Damon Baird, voiced by Fred Tatasciore, is Delta Squad's mechanically skilled and frequently sarcastic soldier. He initially resents Marcus's appointment as squad leader, but becomes one of his regular companions. His knowledge of machinery and Locust behavior helps the group repair vehicles, use unfamiliar equipment and interpret enemy activity.

Gears of War: Judgment presents Baird as a lieutenant commanding Kilo Squad early in the Locust War. He is tried for disobeying Colonel Loomis's orders and deploying a Lightmass missile against Karn, and is demoted despite helping save Halvo Bay. After the war, he establishes DB Industries, whose automated DeeBee machines become central to COG reconstruction and security. In Gears of War 4 and Gears 5, he supports Marcus and the younger soldiers with equipment and engineering expertise. Samantha Byrne is his partner.

Anya Stroud Anya Stroud, voiced by Nan McNamara, is the COG officer who coordinates Delta Squad's missions in the first two games. She provides intelligence and communications support and develops a close relationship with Marcus. Following the COG's collapse, she becomes a frontline soldier in Gears of War 3. After the Locust War, she marries Marcus, gives birth to JD and becomes the rebuilt COG's first minister. She has died before the events of Gears of War 4; her family and successor, Jinn, refer to her role in the postwar government.

Samantha Byrne Samantha "Sam" Byrne, voiced by Claudia Black, joins the playable ensemble in Gears of War 3. She serves alongside Cole and Baird, taking part in the search for supplies and the subsequent effort to reach Adam Fenix. Her exchanges with Baird are frequently antagonistic and humorous. She and Baird become a couple after the war. In Gears of War 4 and Gears 5, she assists the protagonists as a helicopter pilot.

Jace Stratton Jayson "Jace" Stratton is a COG soldier who had a substantial role in the Gears of War comics before joining the playable cast of Gears of War 3. Drake was initially announced as his voice actor, but Michael B. Jordan voices him in the released game. Jace accompanies Cole, Baird and Sam during the search for supplies near Hanover, and later takes part in the campaign against the Locust. The prequel campaign RAAM's Shadow depicts him as a young civilian caught in the evacuation of Ilima, where he encounters the soldiers of Zeta-Six.

Jack Jack is the name of the hovering support robots that accompany the protagonists. In the original trilogy, Jack opens sealed doors, interfaces with computers and helps the squad complete technical objectives. Baird supplies an upgraded version in Gears 5. This Jack can be controlled by a third cooperative player, and has abilities that scan for enemies, protect allies, disable opponents and temporarily take control of hostile units.

JD Fenix

James Dominic "JD" Fenix, voiced by Liam McIntyre, is Marcus and Anya's son and the principal playable character of Gears of War 4. He and his friend Del desert the COG and join an Outsider community. After the Swarm abducts its inhabitants, JD seeks Marcus's help and joins Kait and Del in trying to recover the prisoners. His decision to become a soldier despite Marcus's objections contributes to their difficult relationship.

In Gears 5, JD has returned to the COG and commands the younger Delta Squad. The revelation that he ordered soldiers to fire on protesters damages his relationships with Del and Kait. His attempt to use the Hammer of Dawn during a civilian evacuation causes further deaths and leaves him seriously injured. He later rejoins Kait's mission and tries to repair their friendship.
