Jacob "Jake" Pentecost is the son of Stacker Pentecost and the brother of Mako Mori. A former officer in the Pan Pacific Defense Corps, he is conscripted back into the organization in 2035 to avoid being sent to prison, to co-pilot Gipsy Avenger with Nate Lambert.
Jake Pentecost is the son Stacker Pentecost, and a woman considered Stacker's "first love."[note 4] Jake is raised in a stable home environment on account of his mother, and had many friends to play with as well.
Stacker's relationship with Jake is a strained one on account of his responsibilities to the Pan Pacific Defense Corps - then as a Ranger- is rarely home to be with his son. Jake quickly became weary of his friends idolization of his father. He later resents the image of Coyote Tango, whom his friends also favored.
When the Category II Kaiju Onibaba attacks Tokyo, Japan, Jake celebrates his seventh birthday with his mother and friends. Jake makes a wish for his father be there for his birthday, but when he doesn't arrive, Jake becomes despondent and refuses to play with his friends.
He tells his mother that he never wanted to a birthday party to begin with. Some time after his outburst, Jake finds a present and unwraps it only to find an action figure of his father and Coyote Tango. Angry, he tosses the action figure aside.
Arrival of Mako
Mako's arrival into the Pentecost family creates a larger schism between Stacker and Jake. At seven years old, Stacker expects Jakes to "look after" a thirteen year old Mako as he adjusts to living with her adoptive father, but wanted them to be friends. He calls Jake "spoiled" because he still has everything, unlike Mako, who lost her entire family in Onibaba attack.
Jake became competitive with Mako in everything they did, wanting to beat her in order to gain his father's approval. However, instead of the encouragement Mako receives, Jake often got admonishment for falling short of Mako's perceived excellence.
Pan Pacific Defense Corps
At eighteen years old, Mako joins the Pan Pacific Defense Corps in 2021, Jake follows suit at the age of twelve. However, because Stacker places all of his "hope and attention" on Mako and not him, Jake and Stacker's relationship continues to falls apart. Mako is closely tutored by Stacker, while Jake is berated by Kwoon tutors for not reaching Mako and Stacker's level, despite getting high scores on his tests and reaching the top of every class. Though Jake eventually comes to love Mako, he falls out of touch with Stacker.
In 2022, Jake meets a fourteen year old Nathan Lambert, another aspiring Jaeger pilot. He and Nathan are trained by Mako, and become friends. However, burdened with the expectations to honor his father's legacy, Jake chooses to disregard his personal safety to gain his father's approval. In 2024 he attempts to pilot a Mark-4 Jaeger on his own and collapses instantly under the strain of the neural load.
When he regains consciousness, Stacker strips him of his cadet status and kicks him out of the PPDC. When Jake is strong enough to stand on his own two feet, he leaves and cuts all ties with his family. In 2025, Jake learns of his father's death.
Joining the Criminal Underworld
Following his disbandment from the PPDC, Jake turns to a life of crime. He relocates to Santa Monica, operating as a Black Market dealer, Jake trades with various other deals for a verity of goods, primarily foodstuffs. Occasionally, Jake makes a profit off of the parts of the original Jaegers (dumped in the Santa Monica Jaeger Scrapyard) that remain in destroyed areas of the Pacific Rim where the poor attempt to eke out a living.
March 3, 2034, Jake learns from Sonny that Giovanni Capello has left his his mansion to attend to business out of town. Jake, knowing that Giovanni collects Jaeger parts and was in procession of the Drift Core belonging to Striker Eureka, sneaks into the mansion. He manages to bypass most of its security to reach the vault where Giovanni kept the Jaeger parts and retrieved the Drift Core.
Rigging a helmet to the Drift Core, Jake imitates a "solo-drift" in the hopes of glimpsing his fathers memories recorded in the Drift Core. Jake experiences his birthday and his father's battle with Onibaba, and his relationship with Mako following her adoption into the Pentecost family. He inadvertently glimpses memories of Chuck and Herc Hansen as he gradually becomes lost in the Drift, and approaches memories of his father's death in Striker Eureka.
In Jake's absence, Mako and Lambert continue to search for his whereabouts. When discussing his whereabouts with Secretary-General Mako Mori, Lambert, disappointed, points out that Jake's name constantly pops up in criminal circles. Nate refrains from speaking ill of Jake, knowing that Mako recognizes his as her brother still.
Though Mako believes he still considers Jake his brother, Lambert makes it plain that he doesn't and that it would best to forget Jake altogether. Following the death of Jan Sokk, and the arrest of Ysabel Morales, who sabotaged the Chronos Berserker, Mako decides to proactively begin searching for her brother in the hopes of bringing him back to the PPDC.
Pacific Rim: Uprising
Jake is asked by Sonny to obtain a plasma capacitor from the decommissioned Jaeger, Romeo Blue from the Santa Monica Scrapyard. Sonny and his men accompany Jake into the scrapyard where he leads him into the Conn-Pod. Inside, Sonny warns Jake not to double-cross him, as his recent string of betrayals have put him on thin ice with every crime boss and dealer in the Santa Monica area. Jake reminds Sonny that, though he stole form him, he was also stealing for him, as per “the circle of life”.
Jake uses a tracking device to pinpoint the location of the plasma capacitor; he realizes that the capacitor is moving and no longer inside the Conn-Pod. Sonny wrongly assumes that Jake has decided to betray him anyway. Jake tries to explain that he can still get them the capacitor, but is forced to flee when they begin shooting at him. Jake is pursued through Romeo Blue, evading certain capture. He runs toward a sealed hatch and appears to be trapped. Sonny and men converge on Jake and prepare him to kill him when they step onto a hatch Jake is already aware of. Using his foot, he steps on the mechanism that opens the hatch and traps them down below.
With Sonny out of the way, Jake continues to pursue the moving target with his tracking device until he reaches an exit. Thief escapes with the capacitor as the police arrive, preventing Jake from following immediately.
Jake follows the thief to a warehouse and enters through the window while they’re distracted. Observing the wall of their room, Jake recognizes PPDC propaganda and newspaper articles chronicling the Kaiju Wars. Hearing a nearby machine power up, Jake follows several power cords that lead him to the hangar where a Rogue Jaeger resided.
Feigning ignorance, Jake allows the thief to get close enough to attack him and evades her. He disarms the girl in seconds and mockingly asks how old she is. Curious, he inquires if she built her “toy” herself, the girl tells him that Scrapper is not for sale. He ignores her aggression and tells her simply that he plans on selling the Jaeger on the Black Market when they overhear police sirens.
The girl leaves him behind and activates the Jaeger. Torn between running or joining the girl, Jake chooses to climb into the Jaeger. He searches the cockpit for a co-pilot mechanism, but the thief tells him that she built Scrapper small enough to sustain a single neural load. Frustrated, Jake demands that she allow him to pilot, but she ignores him and puts the Rogue Jaeger in motion.
Unable to do anything except hold on, Jake warns her that she’ll get them killed, and that he has a better way out the situation. The thief rebuffs him with a reminder that she got them out of the warehouse without trouble and continues to pilot the Jaeger.
When their path is blocked by November Ajax, Jake pleads with Amara not to give up, believing she’s giving in to arrest too easily. Instead, she fires off two smoke grenades in a move to mask her movements, but they’re caught by November Ajax again. When Scrapper burrows into an abandoned building, Jake orders Amara to climb to the top of November Ajax’s shoulders. She follows his orders and Jake ejects an ion battery out of the Rogue Jaeger, causing a short circuit in November Ajax’s systems. Scrapper gets them as far as the beach before it loses too much power to function properly and is summarily disabled by November Ajax.
Conscription into the PPDC
Once arrested, Jake and Amara are thrown into a single holding cell where Jake tries to blame their circumstances on Amara, who reminds him that they were caught because he led the police to her warehouse. Curious, Jake asks her why she built Scrapper; Amara tells him she believes the Kaiju would return and didn’t want to be caught waiting for someone to save her. She built the Jaeger for her protection.
Jake is escorted out of the holding cell into an interrogation room where he comes face to face with Secretary General Mako Mori. Jake tries to reassure his sister that he can get out of the situation without her help, Mako reminds him that he has prior offenses and that the police wouldn’t let him off easily. Shifting gears, Jake asks for Mako’s help “one last time”, and Mako gives him one choice: Reenlist in the Jaeger program to train cadets. Jake objects, expressing disinterest in training children when Mako tells him she wants him to rejoin as a Ranger. Mako makes the decision for him and tells him a carrier is on the way to pick him up from jail.
Jake and Amara are taken to the Moyulan Shatterdome where the two are met by Nate Lambert, to the disappointment of Jake. When Jake casually refers to Lambert by first name, Lambert tells him to call him “Ranger Lambert” out of respect for his rank in the military and mockingly calls him “Ranger Pentecost”. Lambert explains that if they don’t make to training sessions in time they’d be sent back to where they were found.
During Lambert’s speech, Jake and Amara meet Jules Reyes, a J-Tech officer with some knowledge on Jake’s background. When she asks why he returned to the PPDC, Jake flirts with Jules and offers to “explain” his circumstances before Lambert interjects and tells him she’s busy.
Lambert leads Jake and Amara to the cadet living quarters where he introduces Jake as the cadet’s new instructor, replacing Joseph Burke, who departed from the PPDC for financial gain. When Lambert asks if Jake had anything to say to the cadets, Jake remarks that it would be nothing they’d want to hear. Leaving the cadet quarters, Jake is sent to his own personal room where his previous uniform remained hung up.

Reemergence of the Kaiju
- John Boyega speculates that Jake was born in South London.[note 5]
- John Boyega rewrote much of his own dialog in Pacific Rim: Uprising.[note 6]
- In an early draft of Guillermo del Toro's character biography for Mako Mori, is the suggestion that Mako Mori or another child is Stacker Pentecost's "illegitimate war child".[note 7]
- According to a deleted scene in Pacific Rim: Uprising, Jake and Nathan were able to maintain a stable Drift for "four hours and a bit" in a Mark-3 Jaeger.
