"Everything started going wrong the minute you showed up. First Ben, then Alby, and now the girl. Everybody saw she recognized you. And I'm betting you know who she is."
— Gally to Thomas

Gally is a Glader and the Keeper of the Builders who was Thomas' first enemy in the Glade. He serves as the main antagonist of the first book as well as the film adaptation. Gally is said to be named after Galileo Galilei.


The Fever Code

In The Fever Code, Gally is introduced as a ten-year-old boy who helped out in the gardens. Minho enlisted his help with an escape plan, though none of the others (Thomas, Teresa, Newt, and Alby) agreed to come with them. However, their plan was discovered by WICKED, and Minho was punished severely. He beat Gally up at some point afterwards, thinking that Gally's loose tongue probably gave them away. Gally's nose was apparently broken as a result, and it failed to heal correctly.

After Gally has been in the Maze for some time, he one day ventured just beyond one of the Doors in spite of the rules. A Griever immediately attacked and stung him. It was during the subsequent Changing that Gally regained a few memories.

The Maze Runner

In The Maze Runner, according to Winston, Gally has been stung by a Griever in the middle of the day near the West door some time before Thomas' arrival. Thus he had regained a few of his memories.

Gally was despised by most of the Gladers due to his arrogant nature. However, he was the Keeper of the Builders, which must have meant that he was reasonably responsible. Two years after the beginning of the Maze Trials, Gally witnessed the arrival of a teenage boy named Thomas, whom Gally immediately became enemies with, having remembered just enough to know that Thomas had worked with WICKED.

After being interrogated with Thomas by Newt, Minho got into an argument with Gally that ended with Gally running off into the Maze and going missing. After being missing for many days, Gally, scared and dirty, eventually returned to the Glade and warned the Gladers that the Maze's Creators were going to kill them and that the Grievers would take one of them every night. Plagued by a nameless terror as the Grievers attacked the Homestead the first night, Gally snatched planks that are barricading the windows and hit Newt with one of them. Thus a Griever managed to penetrate the Homestead and seize Gally, running off into the Maze.

Gally was brought to WICKED and kept there for several days. When the surviving Gladers made it through the Griever Hole, Gally emerged from the shadows with a knife and, while under control of WICKED, attempted to kill Thomas by throwing it at him. A young Glader named Chuck jumped in front of the knife and was killed in Thomas' place. Thomas, distraught by Chuck's demise, attacked Gally, punching him repeatedly in the face and severely injuring him. While Gally and Thomas fought, a group of adults entered the chamber and killed the WICKED agents. Thomas knocked Gally unconscious and fled with Teresa and the other Gladers.

The Death Cure

In The Death Cure, unknown to Thomas and the other Gladers, Gally was taken into custody by WICKED agents and imprisoned in WICKED's headquarters. During his imprisonment, Gally felt terribly guilty for killing Chuck, even though he had been under WICKED's control. (WICKED told Gally he would be killing Thomas, which he was fine with, and thus he had not fought their control.) Gally made several attempts to escape but was stopped by guards every time. However, a group of spies snuck into the facility. They told Gally that if he acted crazy enough, WICKED would believe he had the Flare and put him in a city somewhere in the United States, where Gally and the spies could meet again and Gally could join them.

Gally later sends a message to Thomas, Newt, Minho, Brenda, and Jorge, telling them to meet him at his apartment in Denver, where he now works for the Right Arm. Gally explains to them how he escaped and tells them that WICKED is after them and Hans, the man who can get rid of the implants in their brains. He also tells them that Teresa and the rest have been there, and if they wanted to join the Right Arm after finding them, they should come see him.

When Thomas and Brenda later find Vince, the leader of the Right Arm, Gally is there with him, and he assures Vince that Thomas can be trusted. Gally becomes part of the "army" that takes the Immunes back to WICKED to take it over. However, when the Right Arm is preparing to blow the place up, regardless of any Immunes left in the Mazes, Gally joins Thomas and the rest.

Gally helps Thomas rescue the rest of the Immunes, going back to the Maze and then fighting against the Grievers and Janson's men before going through the Flat Trans to the last paradise with the Immunes.


The Maze Runner

Stung Gally

In the Maze Runner film, When Thomas arrives in the Glade, Gally gets him out of the Box. When Thomas start running, but trips and falls, the Gladers, except Gally, laugh at this. Later, when Thomas is about to walk into the Maze, Gally pushes him down to the ground. At night, at the bonfire, Gally wrestles with the other Gladers like in contest. Gally wrestles with Thomas, when Thomas knocks Gally down to the ground, but Gally knocks Thomas down to the ground as well, causing him to remember his name. The next morning, Ben gets stung by a Griever and attacks Thomas. Gally and the Gladers manage to get Ben off Thomas. Later, Gally and the Gladers banish Ben from the Glade. Later, Gally watches Thomas run into the Maze to help Minho and Alby, who have gone into the Maze to retrace Ben's steps, when Alby got stung by a Griever. The next morning, Gally is present when Thomas, Minho, and Alby return to the Glade. In the Council Hall, during the Gathering, Gally suggests that Thomas should be punished for going into the Maze to help Minho and Alby. Gally is also present when Teresa arrives in the Glade. Later, when Newt decides that Thomas will spend one night in the Pit with no food. Gally leaves the Council Hall in anger.

Later, Teresa, who has woken up and fled to the tower, throws rocks at Gally and the Gladers, but Thomas stops her and goes up to talk to Teresa, while Gally and the Gladers leave. Later, in the medical hut, Alby starts attacking Thomas, but Newt, Jeff, and Clint manage to restrain him, allowing Teresa to inject the serum she had with her when she arrived in the Glade into his chest. Gally arrives in the medical hut to take Thomas to the Pit. While walking to the Pit, Gally tells Thomas that everything has started going wrong when he arrived in the Glade: Ben got stung by a Griever, then Alby got stung by a Griever, and now Teresa has arrived in the Glade. Gally tells Thomas that the Gladers saw that Teresa has recognized him, and that Gally knows that Thomas knows who she is. Gally locks Thomas in the Pit and walks away.

The next morning, when Thomas and Minho return to the Glade, Thomas and Gally start arguing with each other, but Teresa calls out to them and the Gladers and tells them that Alby is awake. Gally is present when Alby tells Thomas that he remembers that Thomas was WCKD's favorite. During the Griever attack in the night when the doors did not close, Gally, Dan, and Hank hide in the Box from the Grievers. When a Glader tries to tell Gally to let him in and Gally starts to open the doors of the Box, the Glader is attacked by a Griever. After the attack, Gally punches Thomas in the face and blames him for everything that has happened. When Thomas stabs a Griever stinger into his leg to regain his memories, Gally watches Teresa, Newt, Minho, Frypan, Chuck, Winston, and Jeff tend to Thomas. The next morning, Gally takes command and attempts to have Thomas and Teresa tied to the poles and offered to the Grievers in order to pacify them and restore peace to the Glade. Thomas and Teresa break free while Newt, Minho, Frypan, Chuck, Winston, and Jeff fight off one half of the Gladers. Gally and one half of the Gladers stay in the Glade while Thomas and another half of the Gladers escape.

Later, Gally, who has been stung by a Griever, meets the group in the WCKD lab, telling them that they will never be free. He aims a gun at Thomas, but Minho throws a spear into Gally's chest, but Gally survives, while Gally shoots a bullet into Chuck's chest, killing him.

The Death Cure

In the Death Cure film, The Right Arm is at the walls of the Last City trying to force their way in. Janson orders his men to open fire into the crowd. Thomas, Newt, Frypan, Brenda, and Jorge are ushered into two vans by masked people. At their destination, one of them takes his mask off and reveals himself to be Gally. Thomas, Newt, Frypan, Brenda, and Jorge are shocked to see him. Thomas punches Gally in the face for killing Chuck. Newt stops Thomas and calms him down. Newt tells Gally that he, Thomas, and Frypan watched him die, but Gally tells him that they left him to die and that if he and his rebellion group hadn't found him, Thomas, Frypan, Brenda, and Jorge, they would be dead. Newt tells Gally that WCKD has captured Minho and that he, Thomas, Frypan, Brenda, and Jorge are looking for a way into the Last City. Gally offers to help them get into the Last City. Thomas, at first, refuses to follow Gally, but Gally tells him that he can get him, Newt, Frypan, Brenda, and Jorge through the walls.

While walking to Lawrence's home, Gally tells Thomas, Newt, Frypan, Brenda, and Jorge that Lawrence's crew had discovered that he is immune to the Flare and took him to the Last City, where Lawrence patched him up and convinced him to join his crew. Gally tells Thomas, Newt, Frypan, Brenda, and Jorge that Lawrence's crew is working to destroy WCKD. Gally tells Thomas, Newt, Frypan, Brenda, and Jorge not to stare at Lawrence.

Gally introduces Thomas, Newt, Frypan, Brenda, and Jorge to Lawrence. Thomas tells Lawrence that he, Newt, Frypan, Brenda, and Jorge need to get into the Last City. Lawrence lets Gally, Thomas, and Newt go into the Last City while Frypan, Brenda, and Jorge stay behind. Gally leads Thomas and Newt through the city and, after returning to Lawrence's home, shows Thomas and Newt the impressive WCKD building, explaining about their security system. When Thomas asks Gally about the way in that he had mentioned before, Gally shows Thomas Teresa working as a WCKD scientist. Thomas realizes that Gally wants to use Teresa to get into WCKD.

In Lawrence's home, Thomas is reluctant to use Teresa as their way into WCKD. Neither Gally nor Brenda understand his reluctance, but Newt reacts with extreme aggressiveness, screaming at Thomas for still having feelings for Teresa. Shocked about himself, he apologizes. Later, Newt reveals to Thomas that he has been infected by the Flare.

Thomas gets Teresa to follow him into an alley where Gally captures her. Gally and Thomas take Teresa to an abandoned church where Newt, Frypan, Brenda, and Jorge are. Teresa is shocked to see that Gally is alive, and Gally questions her about Minho and the other Immune WCKD test subjects and Thomas forces her to remove the trackers from their necks. Gally, Thomas, and Newt force Teresa to get them into the building. Disguised with WCKD soldier overall uniforms and face-masking helmets, Gally, Thomas, and Newt accompany Teresa to Sub-Level 3, where the Immune kids are stored, while Frypan climbs up a crane, Brenda goes to a parking lot to steal a bus, and Jorge returns to the Right Arm's hideout.

When Thomas, Newt, and Gally discover that Minho has been moved up to the medical wing, Gally takes the kids and a serum that he had retrieved from a vault to Brenda, while Thomas, Teresa, and Newt go to find Minho.

While Gally goes back to find Thomas, Newt, and Minho, Brenda drives the Immune children out of the garage, but is cornered by WCKD soldiers. Brenda fires a flare gun into the sky to signal for Frypan to save them with the crane. Thomas and Newt reunite with Minho and they and him escape from Janson and his men, while Newt suffers more and more from the symptoms of the Flare. Thomas, Newt, and Minho's last chance to escape is to jump out of the window and into a pool that is about 100 ft down. When they get out of the pool, four masked soldiers approach them, telling them to surrender. But suddenly, one of them shoots the other three, takes his helmet off, and reveals himself to be Gally. Minho is shocked to see that he is alive, but Gally, Thomas, Newt, and Minho have to get out of the city in a hurry.

While hiding from the WCKD soldiers with Thomas and Newt, Minho asks Gally why he is helping them, as he put a spear through his chest. Gally tells Minho that nobody is perfect.

Back at Lawrence's home, Jorge arrives with his berg and Vince to rescue Frypan, Brenda, and the Immune kids. They fly into the city to get Gally, Thomas, Newt, and Minho.

Newt is getting worse every minute and is not even able to walk alone. So Gally and Minho run to find Brenda with the serum and bring her to Newt. Gally and Minho hear Teresa's voice broadcasted throughout the city, calling Thomas back to WCKD, telling him that his blood is the cure and he can save Newt like he did Brenda. But when they and Frypan arrive with Brenda, Thomas has killed Newt. Thomas then walks off back to WCKD, leaving Gally, Minho, Frypan, and Brenda to gather around Newt.

Gally, Minho, Frypan, and Brenda return to the berg where Jorge flies them, Vince, and the Immune children to the top of the WCKD building where Thomas and Teresa are. Thomas is too wounded and weak to get on the berg due to being shot in the stomach by Janson, but with Teresa's help, they and Vince manage to haul him on board. Teresa falls to her death when the WCKD building collapses. As Jorge flies Gally, Thomas, Minho, Frypan, Brenda, Jorge, Vince, and the Immune kids away from the building, Gally bandages Thomas' wound.

Gally, Thomas, Minho, Frypan, Brenda, Jorge, Vince, and the Immune kids fly to the Safe Haven to live in peace.

Physical Appearance and Personality

In The Maze Runner, Thomas describes Gally as a fifteen-year-old boy who was tall and skinny and has black hair, green eyes, and a nose that is the size of a small fist that resembled a deformed potato. Gally has bad teeth that have come nowhere close to the colour white. His voice was described as being scratchy. Gally was quick to anger while in the Glade, although he was friendlier as a child. In The Death Cure, Gally and Thomas were able to put the past behind them and become friends and allies.

In the films, Gally is portrayed by Will Poulter, who has dirty blond hair. While an antagonist, Gally does seem to have some redeeming qualities, as he tries to look out for the other Gladers.
