(Capcom's primary storyline)
"Welcome to the family, son!"
Jack Baker was the patriarch of the Baker family of Dulvey, Louisiana. He was the husband of Marguerite Baker and father to Zoe and Lucas Baker. He and his family were behind a series of kidnappings and murders from 2015-2017, due to the control of Eveline.
At some point in his life, Jack served in the United States Marine Corps. He also became the owner of a 19th-century ranch in the Louisiana countryside, possibly handed down to him by his family, married Marguerite Baker and sired two children, Lucas and Zoe.
Meeting Eveline Edit
In October 2014, Jack was thinking of reinforcing the family ranch with Lucas' help in response to local weather forecasts predicting a hurricane. The resulting storm destroyed their old house and crashed a tanker into a nearby bayou. Lucas discovered the ship and informed his father, who decided to investigate it the next day.
The Bakers found Mia Winters and a young girl named Eveline on board the tanker and took them in, unaware that Eveline was a highly advanced human bio-weapon and Mia her escort. Eveline infected them with her mold as soon as she woke up, triggering mutations within their bodies and manipulating them to see her as part of the family. When the influenced Marguerite attacks Zoe in the bathroom, Jack runs in and restrains Marguerite, ordering Zoe to grab some rope from the garage. But by the time Zoe returns, Jack is also taken over by the mold and attempts to drown Marguerite in bath water. Jack mutilates himself in an act of "devotion" to Eveline before proceeding to chase Zoe around the house. Although his daughter manages to escape, Jack immediately turns his attention to Lucas and brings him into his old room to "meet Eveline".
Under Eveline's control Edit
Jack and his family (except for Zoe) went completely insane and eventually withdrew from community life altogether, causing the local parish to declare them missing. Occasional sightings of the Bakers led to rumors that the residence was haunted.
As Eveline became more obsessed with expanding her family, the Bakers were enlisted in abducting tourists and homeless people. Jack was responsible for killing, dissecting, and skinning the victims, whose bodies became the Molded, while Marguerite used their organs as a source of food. Zoe attempted to communicate with the victims and help them escape, which caused Jack and his family to disown her.
Jack briefly interacts with Marguerite while she travels to and from one of the bedroom to "care" for the sole surviving member of Sewer Gators, Clancy Jarvis. He enters a severe argument with Marguerite, which incensed her so much that she burst into Clancy's bedroom and repeatedly stabbed him, although Jack stopped her before she could deal a lethal blow by apologizing and reassuring her that he loves her.
Jack, after foiling a prior escape attempt by Clancy, had the latter locked in the basement until 5 AM so he could "meet some friends of his", referring to the Molded. Upon realizing that Clancy would not be defeated so easily, Jack personally confronted him at around 5 AM, but was defeated.
Ethan's arrival Edit
The following month, Mia's husband Ethan arrived at the house in search of his wife. After fending off a possessed Mia, Ethan is knocked out by Jack and brought to the main house. Jack ties up Ethan at the dinner table, intending to feed him pieces of meat and organs from various human victims, which was one of several methods the family used to turn their victims into Molded. When Ethan refused to eat, Marguerite stormed out of the room while Jack began stabbing him. However, he was unable to deal a fatal blow due to the arrival of a Dulvey Parish deputy investigating the area. Ethan used this opportunity to escape, although Jack quickly found out and began looking for him.
Eventually, Ethan meets the officer in the garage and once there, Jack closes the door and executes the deputy from behind with a shovel. Jack fights with Ethan and Jack is seriously injured, but manages to hijack Ethan's car, driving it into a pile of loose metal scaffolding, which then explodes. Although Jack himself collided with one of the protruding metal bars and was badly burned in the explosion, he immediately recovers and continues to chase Ethan. Jack grabs Ethan's handgun and points it in his mouth, telling him that he is about to witness something "wonderful" before blowing a hole through his own head.
Second encounter with Ethan Edit
Later on, a visibly burnt Jack surprises with his head injuries now partially healed, and begins stalking Ethan throughout the house once more. Jack also takes a marble dog head piece with him to the dissection room in order to ambush Ethan, knowing that he would need it to escape the house. He also talks to the corpse of the deputy before leaving, stating he'll need his help in dealing with Ethan, with the plan of turning the deputy into a Molded.
After a small skirmish, Jack grabs an oversized, man-made pair of chainsaw-shears. Eventually, Jack is injured to the point where his upper body explodes, leaving only his legs intact. Despite this, his legs start to stand and walk, but eventually fall to the ground, once again, seemingly dead.
Final battle with Ethan and death Edit
The loss of his upper body triggered a mutation which led to him increasing multiple scores in size and transforming into a reptile-like monstrosity, sporting several eyeballs and completely covered in Eveline's black essence. He confronts Ethan in a boat house while the latter is rescuing a captured Mia and Zoe. While swearing at Zoe, Jack ends up screaming about how they're being plotted against, and how Ethan continues to plot against him. Jack's speech has also become much more demonic and strained. At several points during the battle, he cries out Marguerite's name in agony and yells at Ethan for killing her, revealing that he is well aware of her death at Ethan's hands.
Ethan defeats Jack by taking out his eyes, causing him to retreat into the flooded section of the outhouse. Seconds later, Jack ambushes Ethan from underwater and begins to swipe at him in a confined space, inadvertently allowing his final eyeball to be exposed and destroyed. Jack's carcass begins to rot away, and Ethan tries to escape with Zoe and Mia. However, Jack grabs Ethan once more, readying for another fight. Zoe tells Ethan to use a dose of the serum on him. When Ethan does, Jack calcifies completely, killing his body for good.
Despite being deceased, Jack appears in Ethan's dream. Now free of Eveline's control, he expresses deep remorse for his actions, revealing to Ethan that his family were corrupted and did not wish to harm anyone. Jack then begs Ethan to save his family from Eveline, right before Ethan wakes up from the dream.
Prior to Eveline's arrival, Jack Baker was a family man. However, he was not above physically disciplining his son Lucas, once having slapped him for using his cellphone at the dinner table. He also did not tolerate cursing, scolding Lucas for cursing during breakfast. Under Eveline's influence, Jack is a highly sadistic and violent individual who wears a manic grin most of the time, and was willing to attack anyone who had angered him at the slightest provocation. He is very abusive towards his son Lucas, even slicing his arm off at one point (with Lucas himself implying that this wasn't the first time it happened). He's also verbally abusive towards his wife and made a motion with his hand implying that he was going to hit her. Even under Eveline's influence, however, it is revealed that he ultimately still cared for his family, as he was genuinely angry that Ethan tried to get Zoe to turn against him (even though Zoe was already against him long before Ethan arrived) and that he had killed Marguerite. In a rare event in 'Bedroom', Jack has an argument with Marguerite about Clancy being in the house, but eventually apologizes and reassures her he loves her.
When Ethan meets Jack again in Eveline's hive mind, he shows deep remorse for his actions, and says that he would never had hurt him if it wasn't for Eveline's influence. He showed sympathy for Eveline, telling Ethan that all she wanted was a family, and then begs Ethan to free his family from Eveline.
As a benefit of his infection by the Mold, Jack possesses a significantly increased strength threshold that far belies a man of his age and build. Jack has been shown to effortlessly throw Ethan through walls, tear off the roof of a car with his bare hands, and wield obscenely large weapons in combat, including man-made shears. He can also use smaller weapons with amazing precision and strength, as shown when he destroys a dinner table with a shovel, splintering it.
Jack's regeneration is on a whole different level as compared to the rest of the Baker family. He is a constant enemy throughout the game as he is invulnerable to conventional means of attacks. Even when shot in the heart or the head, it will only stun him for a few seconds, and though he can 'die' if damaged enough, he will simply rise again after a set period of time. Examples of his superior regenerative powers are (in order of sequence): run over by a car, impaled by girders in a car crash, lit on fire, engulfed in a fiery car explosion, and finally getting a self-inflicted shot in the head, blowing a hole through the right portion of his skull. He still comes back for more throughout the game as his upper body explodes following a fight with Ethan Winters due to repeated attacks from a chainsaw. Jack then regenerates into a monstrous entity, with his eyes bulging out of its sockets, with him being covered in Eveline's contamination. The only thing that truly stopped him was the administration of the serum, calcifying his body, and thus removing the threat of Jack Baker for good.
