Jim Johnson, formerly known as Zarinthkampta 42-79, was a resident of an unknown world, living a peaceful and happy life amongst a society of technologically advanced individuals beside his sister and nephews. But it was not to last, Red-Eyes quickly seized dominion of the planet and consumed Jim's nephews, leaving him and his devastated sister Evelyn to flee from their doomed home. However, Jim lost his sister and Jim even wasn't clear about what happened to her.
After months drifting aimlessly through space, Jim found Earth and opted to land their ship despite his fears and uncertainties. Misfortune once again befell Jim when his sister vanished without a trace, sending his emotionally crippled being to seek refuge in Addison Apartments where he was greeted by the enigmatic Alyson Rosenberg and the lovely Lisa Garcia. Throughout his stay, he was plagued with mass hallucinations of his beloved sister Evelyn. Jim became infatuated with Lisa after all she had done to help him adjust to the apartments and eventually asked for her hand a year after his arrival.
Despite continued nightmares of Evelyn, Jim lived out a happy life and eventually became the proud father of Larry. But his happiness soon came to yet another end when Red Eyes revealed himself to have followed the alien from his doomed planet to Earth. Jim's grief only worsened when he lost his stillborn daughter.
After his nightmares began to depict the death of his new family, Jim joined the Devourers of God in hopes to learn more about Red-Eyes and keep his loved ones safe in the process.
Jim vanished without a trace the day after Larry killed Mrs. Gibson's pet rabbit by accident with his firecrackers, leaving his family with a feeling of great loss, one that was especially strong within his son.
After the arrival of Sal Fisher, Jim appears in the form of a phantom in the treehouse to make an effort to communicate with the boy but is only able to give reversed and chopped up dialogue, the only eligible words he speaks are "red ball", the sign that he was making contact with Sal.
The Phantom of Jim offers Sal indecipherable garbled communication throughout the events of the Bologna Incident and the death of Mrs. Packerton. He only emerged a couple of years later after the Red-Eyes Infestation and the Mass Murder at Addison Apartments to reassure Sal that killing all who were infected by the demon had to be done in order to prevent it from spreading.
When Dr. Enon is scared into plummeting to his death at the sight of a ghostly Larry Johnson, Jim was quick to report it to Sal as well as deliver a warning that "73 hours remain." Foreshadowing the boy's trial and the death penalty.
Little is known about Jim's personality. In his journal, he writes about caring deeply for his family and becomes very emotional when tragedy befalls them. Larry also recalls that his parents hardly ever fought and that they loved each other very much. This suggests that Jim was a loving father and husband before his disappearance.
Jim has a bald head, thick eyebrows, and a handlebar mustache, both russet red. His eyes are green. He appears middle-aged and is depicted wearing a leather jacket and green shirt.
Jim himself doesn't necessarily speak. However, he appears to Sal as The Phantom in Larry's Tree House in The House of the Wretched. He makes brief appearances to Sal in dreams three days before the boy's trial to share the death of Dr. Enon in The Bologna Incident.
The Bologna Incident also includes chopped up and mysterious dialogue throughout Sal's schoolday and investigation of Mrs. Packerton's apartment room 201.
The Trial also includes him appearing to Sal as The Phantom in Mr. Addison's room in Addison Apartments after Sal picks up the knife. He tells Sal that they had no choices but to do the kills.
- Jim is one of the three characters in the game that aren't human, the other two being the Red-Eyed Demon and Terrance Addison.
- Larry is not at all like his father appearance-wise, but he inherited his love for Metal music from him.
- From his secret journal we can find out that he is an Alien and he came to the Earth after his planet was destroyed because of a shadow attack and the first resident whom he met was Miss Rosenberg.
- According to his journal, Jim Johnson is the name he took up after coming to the Earth for a year because his real name "Zarinthkampta 42-79" will raise some suspicion.
- It is also one of system files in the game.
- All the strange things in the apartment occur before Jim's appearance, however this is likely due to the fact that the Devourers of God have been in operation since the 18th Century.
- According to Larry, Jim used to live in the 503 room in Addison Apartments before he and Lisa got together.
