Louis Tully talking with Dana Barrett in the hallway of their apartment building.
was
Dana Barrett's neighbor across the hall in the infamous
Shandor Building in New York. He had a job as an attorney, but got his law degree at night school and mainly handled taxes. Hopelessly in love with Dana, Louis would constantly make up excuses to see her, even going as far as ambushing her whenever she was coming or going from her apartment.
During a party thrown for his clients as a business expense, Louis suddenly found himself targeted for possession by Vinz Clortho, the Keymaster of Gozer, who appeared as a large, powerful dog-like demon in Louis' bedroom during the party. An unaware Louis threw a pair of coats on the beasts' head and a moment later the demonic monster exploded through his bedroom door, grunting and snarling while searching the room full of frightened guests. Although he initially escaped from the seemingly clumsy Vinz, the Keymaster chased Louis outside of the building and ultimately cornered him in Central Park, growling ferociously at Louis who fainted in response. The demon then took over his body. Under Vinz's possession, Louis seemingly became an even goofier version of himself as he aimlessly sought out Zuul the Gatekeeper, who had earlier possessed the body of Dana Barrett.

After being inhabited by Vinz, he wandered around Central Park mumbling to himself and scaring off random strangers before clumsily mistaking a carriage horse for the Gatekeeper. The horse's coachman interrupted Louis as he was rambling, angering him and causing him to flare his eyes red and growl monstrously at him. Louis then ran off yelling threats about the coming of Gozer before getting arrested by police and dropped off at the Ghostbusters headquarters. Egon Spengler interviewed him and scanned his brain, which revealed an image of the same Terror Dog that had attacked Louis earlier. The possessed Louis spoke giddily about the coming of Gozer before their conversation was interrupted by a phone call from Peter Venkman, who had just encountered Dana Barrett who was now calling herself the “Gatekeeper” while under similar demonic possession. The following day a representative from the EPA came to the Ghostbusters headquarters and forced the shutdown of their protection grid, causing an explosion which released all of the captured ghosts. Louis seized the opportunity to escape and continue his search for the Gatekeeper, walking around in the midst of the supernatural chaos, eventually finding his way back to his apartment building. As Louis approached Dana Barrett's apartment, the door swung open revealing her, under Zuul's demonic trance, awaiting seductively inside. Louis introduced himself as the Keymaster, to which a smiling Dana responded eagerly, introducing herself as the Gatekeeper. The disheveled Louis immediately entered her apartment with excited terror in his eyes, as he entered the living room the door magically slammed shut behind him.
The possessed Louis finally finds an equally possessed Dana.
Standing before his Gatekeeper, Louis stopped to stare in awe as Dana rose seductively from her sofa. Louis' jaw dropped at the sight of her spectacular body, wearing a shimmering, flowy red dress sauntering seductively toward him with a wanton look on her face. Louis' arms opened wide as she approached him and the two demon-possessed neighbors embraced, sharing a long, passionate kiss before turning toward a hidden staircase leading to the
Temple of Gozer where they had sex as part of the ritual to open the doorway into the spirit world and allow Gozer to enter the human realm. Upon concluding their satanic union, Dana and Louis rested before taking their places atop the pedestals which previously contained the statues of their possessors. Atop their pedestals they awaited anxiously for the moment to open the doors to the Temple of Gozer. As the Ghostbusters made their way toward the rooftop, he and Dana began opening the gate by raising their arms to the sky, triggering twin streams of supernatural energy to strike them. The demon-possessed couple redirected the energy toward the massive door in front of them, causing it to grind open. Louis and Dana smiled as they completed opening the doorway, then they lowered their arms toward the pedestal surface, unleashing large blasts of lightning which triggered their transformations into the grotesque, demonic, Terror Dog forms of their possessors, Vinz Clortho and Zuul. Louis, in Terror Dog form, roared as he and Dana moved about atop their pedestal, getting used to their new forms. Louis wagged his tail as he smiled at Dana from afar, before noticing the Ghostbusters, who arrived just in time to witness them becoming otherworldly monstrous hellhounds. Louis joined Dana in growling ferociously at them from afar. Afterwards, Louis barked as he leaped toward the Temple of Gozer as Dana followed behind him with a monstrous snarl. The Terror Dogs took their places beside the doorway and awaited Gozer’s imminent arrival.

The doorway opened and Gozer the Gozerian began to emerge. Louis and Dana stared at the gate as Gozer exited. As Gozer materialized, Louis kept a watchful eye on the Ghostbusters while Dana continued to stare at her. Gozer began to approach Louis, which he sensed. He turned his large head towards her and bent down. Gozer then proceeded to pet the Terror Dog. Louis rolled his glowing red eyes and purred loudly in unison with Gozer as she pleasured her loyal pet, all while Dana stared on longingly from afar, awaiting her turn with her master. Gozer eventually let go and Louis turned back toward the Ghostbusters. As Gozer approached Dana, the team spoke up, asking her to leave this world. Gozer replied asking them if they were gods. They replied no, promptly leading to Gozer commanding them to die and unleashing streams of lightning at them from her fingertips. Louis stared at them and growled while Dana turned to Gozer and roared loudly in approval. After the team regrouped, they began to march towards Gozer and her pets. Louis stared at Gozer while she and Dana stared intently at the team. When the
Ghostbusters destroyed Gozer by crossing the streams reversing the particle flow through the gateway, both Vinz and Zuul were burned to a crisp by the resulting blast. Louis and Dana survived however, and were extracted from within the
Terror Dogs' burnt corpses by the Ghostbusters. Louis never knew that he and Dana had sex while they were possessed, and when he asked, she denied it.
Louis, after transforming into a Terror Dog, purrs and grins as Gozer pets him.
Five years later, as thanks for helping him, Louis served as the Ghostbusters' lawyer during their trial in
Judge Wexler's court. Louis proved to be a hopelessly inept lawyer, but the day was saved by the appearance of the
Scoleri Brothers, whom the Ghostbusters caught after Wexler rescinded their restraining order.
Afterwards, Louis became the personal accountant for the Ghostbusters. During this time, he had an affair with Janine Melnitz and found a personal enemy in Slimer when the green ghost began hanging around the firehouse all the time. When the Ghostbusters went to battle Vigo the Carpathian, Louis, donning a spare uniform of Egon's, hurried to catch up so he could help them, encouraged by Janine. The moment at which he fired his particle thrower at the slime shell covering the Manhattan Museum of Art was the moment the Ghostbusters destroyed Vigo, causing the slime to weaken and be blasted apart easily by Louis, who was hailed as a hero by the crowd of onlookers.
