Due to the radically skewed population and wealth distribution on Earth Jack Cooper's family relocated to the Frontier in search of a better life when he was an infant. The rural Frontier community they inhabited was subjected to harassment and exploitation by IMC garrisons. As the IMC continued to disrupt the livelihoods of the people in his home system, Cooper volunteered as a Militia Rifleman to free the Frontier from the oppression of the IMC. One of his first assignments as a rifleman was during the battle of Fracture, where he suffered a head injury in the line of duty and had trouble remembering his involvement as a result.
Titanfall 2 Edit
Tai Lastimosa begins to train Jack Cooper as a pilot despite it technically not being allowed. The training session is interrupted when the 9th Militia Fleet arrive at Typhon. Cooper and Lastimosa are deployed to the planet's surface. During the first battle on the planet, Cooper's battalion is ambushed and surrounded by Spectre units. Apex Predator Titans show up to finish off the grunts, but Cooper is protected by Lastimosa and BT-7274. Lastimosa is mortally wounded in the process.
Cooper awakens to find Lastimosa barely alive. With his last breath, Lastimosa transfers control of BT to Cooper. After giving Lastimosa a proper burial, Jack takes Lastimosa's jump kit and helmet and meets BT-7274, who recognizes Cooper as his new pilot.
Jack retrieves batteries for BT, and the duo escapes into the wilderness in an attempt to locate Major Anderson to complete Lastimosa's mission.
The two come across The Reclamation facility, where a battle is occurring between Militia and IMC forces. Cooper and BT fight through the facility and make their way to Kane, an Apex Predator responsible for the death of many Militia pilots in the battle. They kill Kane, and Cooper takes his helmet radio.
They press on, and find an IMC factory lead by Ash, an Apex Predator and simulacrum pilot. Ash torments him throughout the facility, which builds testing grounds for captured Militia soldiers. Jack and BT confront Ash and kill her by crushing her in BT's fist.
Afterwards, they arrive at Anderson's coordinates which are at a classified IMC research facility. Once Cooper ventures inside he experiences strange phenomena, which is later revealed to be a result of time anomalies in the area. They then locate Anderson's body, lodged in the ceiling. After Cooper retrieves Anderson's helmet, they uncover his mission: he was sent to the facility to locate and identify a new weapon being developed by the IMC. During the briefing hologram, they also discover that Anderson had been given a wrist mounted device which would allow safe passage through the facility. With Anderson's death, the command of Special Operation 217 transfers to Cooper. Cooper locates the other half of Anderson's body and takes the wrist mounted device. He then finds out that the wrist mounted device is actually a time travel device, which allows its user to travel forwards or backwards in time with a simple flick of the wrist. As Cooper ventures deeper into the facility he runs into various enemies such as Prowlers and Stalkers, as well as IMC grunts from the past. He creatively defeats his enemies by using the time travel device. He eventually finds Anderson's objective: an IMC super weapon known as the 'Ark', which works by folding space and time to create untold levels of damage and destruction. Cooper discovers that the version being tested at the facility was a scaled-down prototype, and that the IMC have a full-scale version ready to go. BT and Cooper then leave the facility and search for a location to contact the main Militia fleet.
Jack and BT soon reach Typhon's beacon, an enormous satellite dish currently under the control of Militia survivors. After retrieving an Arc Tool and reactivating the reactor that powers the dish, Jack, with BT's throwing arm, repairs the dish. Before they can make contact, Richter, an Apex Predator, arrives. Jack and BT defeat the freelance pilot and reestablish contact with Sarah Briggs and the Militia 9th Fleet.
When Sarah arrives with reinforcements she doesn't approve of BT linking to Jack, a lowly Rifleman. BT protests, and she allows the duo to remain connected. She then initiates an attack on the base containing the Ark weapon, but the attack ultimately fails when the Ark is loaded onto the IMC Draconis, a large transport vessel, which then flees the area.
Jack and BT meet up with the bulk of the Militia forces, which pursues the IMC Draconis and the Ark. With the aid of the The 6-4, Jack takes control of the Malta battlecruiser, which was hindering Militia pursuit of the Ark. Jack and BT then battle Viper and kill him, but the Draconis crashes seconds later due to damage sustained. After being captured from the wreckage by Blisk and Slone, BT is seemingly destroyed. Cooper retrieves the Titan's emergency SERE Kit, which allows him to escape captivity. Jack plants BT's data core in a new Vanguard chassis and tracks down the Ark. After confronting and killing Slone, Cooper attempts to sacrifice himself to destroy the Ark, but BT throws him away from the blast. Jack is then saved by Barker, but BT is destroyed in the resulting explosion.
Cooper is hailed as a hero and officially sworn into the SRS, although he is reluctant to be assigned a new Titan, because nobody can ever replace his fallen friend.
- Although his ethnicity is assumed to be Caucasian, in the Art of Titanfall 2 book, Lead Artist Joel Emslie said of his appearance, "We went for the look of a guy who might be a mix of ethnicities with a hint of Benecio Del Toro."
- He was present at Operation: Fracture, and suffered a concussion that led to a minor case of amnesia.
- Cooper has a tattoo on his left arm, though it cannot be fully seen as it is partially covered by his clothing.
