- ―Samuel Loomis to Michael Myers[src]
In the movie Halloween H20: Twenty Years Later, a retcon was established which ignored the events from Halloween 4, 5, and 6. As a result, the biography of this Loomis is drastically different to the one who appears the H20 timeline onwards. This version of the character appears in Halloween, Halloween II, Halloween 4: The Return of Michael Myers, Halloween 5: The Revenge of Michael Myers, and Halloween: The Curse of Michael Myers.
On November 5, 1963, six-year-old Michael Myers had been admitted to Smith's Grove Sanitarium for the October 31st murder of his older sister Judith. The child (now seven) was blank, emotionless slate to Loomis, never speaking, barely even moving. Sam recognized the deep-rooted trauma in the boy's psyche and knew that special treatment would be required if he were to ever help him. Loomis petitioned his superior, Doctor Carpenter to have Michael moved to a private room, but Carpenter declined the request and insisted that Myers remained inside the open juvenile ward.
Over the following year, Loomis paid close attention to Michael, but grew concerned when certain incidents began taking place. One such incident involved an injury relating to a fellow patient named Tony O'Malley. Tony suffered many of the same derangements as Myers, but unlike Michael, was prone to violent outbursts and displays of emotion. After witnesses recounted seeing O'Malley bullying the smaller Myers, he was soon discovered with a crayon lodged inside his eye. Nobody suspected that the virtually comatose Michael Myers could be capable of such an attack, but Loomis began to suspect otherwise. Another such incident took place in November of that year when a patient named Adrian Wade ate an entire birthday cake that was intended for Michael. He was later found in the shower room with 2nd degree burns all over his body. He died in the medical wing a short time later. Another boy, Roger , bit off his own tongue and choked to death. There was no obvious evidence linking Myers to these two deaths.
Over the span of the next several years, Loomis continued to treat Michael. He never gave up hope that he might be able to pull something out of the boy's withdrawn psyche.
On May 1, 1964, Dr. Loomis meets with two superior doctors in the sanitarium's forum chamber. Loomis suggests that his patient be confined in a maximum-security ward located at Litchfield, Illinois. The two doctors brush off Loomis' request declaring that Michael was merely "a catatonic" exhibiting "comatose behavior" who does not react to any of his surroundings. Loomis insists he be taken seriously because he is convinced that his patient's blank behavior is an ingenious cover for his true nature. He also feels that the level of security at Smith's Grove is insufficient. He pleads that Michael be moved immediately to a facility where any possible escape or legalized freedom is impossible. The Smith's Grove superiors decline the doctor's requests and issue an ultimatum that Loomis keep Michael as his patient or he will be looked after by someone else. Loomis knows to his core that no one else can be trusted or even safe around Michael, so he agrees to stay with him.
At some point Loomis became close with a colleague named Doctor Jennifer Hill. Hill shared many traits with Loomis; she was politically liberal and held the same views as he concerning psychotherapy—that "insanity was possibly the reaction of a sane mind to a sick society". The two eventually fell in love and were engaged to be married.
In 1971, Doctor Carpenter suggested having a Halloween party in the juvenile ward. Doctor Loomis was vehemently opposed to this idea given the significance of this particular date in relation to Myers. Again, Carpenter dismissed Loomis' concerns and the party went underway. A faulty generator knocked out the electricity during the party and when the power resumed, the staff discovered a girl named Nancy had apparently slipped, hit her head and drowned while bobbing for apples. Loomis noted the irony of the fact that she was seen teasing Michael only shortly before hand.
That same evening, Michael killed Doctor Jennifer Hill. Sam found her body lying on the ground outside the hospital. It appeared as if she had fallen from the roof of the building and her death was written off as a suicide. This proved to be the breaking point for Doctor Loomis. After spending eight years trying to reach him, he now committed himself towards making sure that Michael Myers never saw release ever again. Acting as Michael's gatekeeper became an obsession with Loomis. He no longer regarded him as a human being, but as a monster and devil, the living epitome of pure evil.
Michael turns twenty-one on October 19. By law, he is to be presented to court on his birthday for trial. The final verdict determines his freedom or further confinement. The trial date is pushed two weeks into the first week of November.
On the rainy night of Monday October 30, 1978, Loomis is accompanied by his friend and medical assistant Nurse Marion Chambers; they are charged with transferring Michael back to his home county for the trial. Loomis reveals to Marion that Thorazine will be used before Michael is presented to the judge.
When the pair reach the gates of the sanitarium, they discover that many patients are wandering around the grounds. Loomis goes to the main gate to telephone the hospital, but Michael appears and nearly attacks Marion while she is waiting in the car.
Myers escapes from the Illinois state hospital hijacking the car meant for his court date transfer. His plan is to return to his hometown of Haddonfield and locate his last surviving sibling. Driving the 150 miles (241 km) to his destination, he arrives in Haddonfield in time for Halloween.
Loomis is on Michael's trail for the entire date of October 31. While en route to Haddonfield, Loomis stops along a rural highway in west central Illinois to call Haddonfield authorities. He has every reason to believe Michael will return home, so he urges that the police watch out for him
When the psychiatrist finally arrives in Michael's hometown, he seeks the help of Haddonfield Memorial Cemetery's grave keeper. The pair discover that the headstone of Judith Myers had been dug up and is missing. This clue is enough to assure Loomis that his patient is physically in the city. That afternoon, Loomis enlists the help of Haddonfield's sheriff, Leigh Brackett. The pair later travels to the former Myers residence at 45 Lampkin Lane. Loomis is curious to know if Michael had returned to his childhood home. With the front door being broken into and the decaying carcass of a stray dog being indoors, these two clues reassure Loomis that Michael has indeed come home. Loomis tries to convince Sheriff Brackett that Michael is a human incarnation of pure evil, that he has returned to kill again, and that Haddonfield is not safe on this night until Michael is captured.
While Michael stalks Laurie Strode and her friends, Loomis waits and watches over the house, believing that Michael will return to his home. When he discovers the stolen car, he begins combing the streets where he finds the two children that Laurie was babysitting running frantically from a house. Loomis investigates and sees Michael attacking Laurie. When she pulls Michael's mask off, he stops to re-apply it, giving Loomis the opportunity to shoot his patient six times, knocking him to and off the balcony of the two-story house. After agreeing with Laurie that Michael was "the boogeyman", Loomis walks over to the balcony and looks down in horror to see that Michael is gone.
Haddonfield Hospital massacre
Laurie is taken to Haddonfield Memorial Hospital while Sheriff Brackett accompanies Loomis in his search for Michael. While searching, Loomis believes that he has found Myers who quickly runs away from the police only to get hit in a car crash. While everyone believes the shape is now dead, for some unknown reason to Loomis, he can't be too sure. It is at this time when Gary Hunt arrives and tells Brackett that his daughter Annie was found dead. They arrive to the Wallace home where Leigh has to id his daughter and he leaves his duties to Hunt as he has to tell his wife the news, but before he goes he blames Loomis for what has happened. Loomis and Hunt then go to the coroners where they try to identify the body that was burned. It turns out that it was in fact not Myers but Bennett Tramer. Loomis and Hunt then head towards an school where Michael has written the word "Samhain" on the chalkboard in blood. It is at this time that Dr. Loomis is ordered to leave Haddonfield by the state governor so as to not create panic. His assistant Nurse Marion Chambers has arrived to try convincing Loomis to leave Haddonfield. She also reveals to him one horrifying fact: Michael Myers is the brother of Laurie Strode. After hearing this, Loomis hijacks the police car that is taking him away from Haddonfield using his gun and arrives at the hospital to stop Myers.
Loomis races to Laurie's aid and, once again, fires multiple gun shots to Michael which, naturally, does not stop him. Loomis and Laurie run to a nearby operating room where Loomis attempts to destroy Michael with a gun shot to the head. Not realizing his gun is empty, Loomis fires an empty chamber, and Michael angrily stabs him in his stomach, causing Loomis to collapse. Nevertheless, Loomis recovers, and he and Laurie fill the room with oxygen and ether. As Strode runs away, Loomis stays behind. He tells Michael that "it's time" and proceeds to blow himself up with Michael.
Surprisingly, Loomis survives, but is horribly burned, walking with a pronounced limp (possibly due to either the burns in his leg or his stab wound to the stomach) and wearing gloves to hide the burn scars on his hands.
10 years later
In 1980, Laurie Strode had a daughter named Jamie Lloyd. Shortly afterwards, it was thought the couple died in a car crash. On October 30, 1988, Myers, who had been in a coma for 10 years, awakens in an ambulance when he hears that he has a niece. Loomis subsequently confronts Doctor E. W. Hoffman and inquires as to why he was not notified. As Hoffman asserts that Michael was a federal patient and prisoner, Loomis refers to Michael as "evil on two legs" and asks Hoffman if he knew the date. Loomis then asks Hoffman to look at his scars from the explosion at Haddonfield Hospital. Hoffman is then called about a crash, which compels Loomis to quickly leave his office. Hoffman and Loomis arrive at the scene of the crash, where Loomis is doubtful the crash was an "accident" and asks how many people were inside. Loomis then looks inside the ambulance and concludes that Michael had been there but departed before they arrived. Loomis tells the troopers and Hoffman that Michael had escaped and would not be found, which Hoffman rebuffes by insisting that Michael's muscles would be useless even if he was conscious. Loomis states that Hoffman was speaking about him as though he was a human being when that part of him died long ago. As Loomis begins to leave, Hoffman asks him where he is going, to which Loomis answers, "Haddonfield" and that it is a four hour drive. Loomis tells Hoffman that he can reach him through the local police and that he is sure he will find Michael in four hours if they do not.
Arriving at a filling station, Loomis stumbles across a corpse and goes inside another part of the station to find a second lifeless body along with a broken phone. He turns his back to see Michael, and asks him, "Why now?' Loomis drops his cane and steps closer, noting that Michael has waited ten years and states that he knew the day of his return would come, pleading with him to not go to Haddonfield and offering himself as a victim before telling Michael to leave "those people in peace." As Michael remains silent and with no visual response to the pleas of Loomis, Loomis shoots at Michael several times and comes forward to check, discovering that he has missed and that Michael escaped the building. Loomis looks outside and then comes out, looking around and calling for Michael. The latter emerges from the garage in a truck, Loomis shooting at the truck to no avail. Michael drives past Loomis and blows up the filling station, Loomis ducking for cover and observing as the phone lines are caught in the explosion and severed before turning his attention back to the escaping Michael.
Now without a car, Loomis walks down a highway and extends his arm as he notices an incoming car. The car passes Loomis, who briefly shows dissatisfaction before noticing a car with cheerleaders and extending his hand again. The car stops and one of the boys inside, calling Loomis an "old man", encourages him to get inside. Loomis comes up to back of the car to get in, just for them to drive off, blowing smoke in his face. Jackson P. Sayer pulls up behind Loomis and calls for him to get in, Loomis thanking him as he enters the car. Sayer identifies himself and reaches out to give Loomis a handshake, the latter asking how far he is going. Sayer answers and asks Loomis where he is going before stopping short of addressing him by a name. Loomis tells Sayer his name and that he is going to Haddonfield. Sayer asks him if he is having car trouble, and in reference to the filling station encounter with Michael, Loomis replies, "Sort of." Sayer looks at Loomis and figures that he is "hunting it" like him, to which Loomis asks him what he is hunting. Sayer replies and says that you can't kill damnation since it doesn't die like a man does. Loomis answering that he knows that and Sayer identifies him as a pilgrim, offering Loomis a drink. Loomis takes it and drinks while Sayer begins singing, Loomis smiling afterward.
Sayer drops Loomis off at the Haddonfield police station. He announces that he is looking for Sheriff Brackett and is told that Brackett retired. Loomis asks who the new sheriff is, and is answered by Ben Meeker, who identifies himself as sheriff. Loomis begins to say who he is, but Meeker says his name first and remarks that folks from around there, especially officers, are unlikely to forget his name before asking why he is back after ten years. Loomis explains that Michael is in Haddonfield again after escaping from Ridgemont and repeats this when Meeker states his disbelief. Meeker asks Loomis why Michael has returned and Loomis reflects that Michael tried to kill Laurie ten years ago and now has targeted her daughter. Meeker identifies the girl as Jamie Lloyd and Loomis insists she is danger wherever she is. Meeker dismisses this by citing the fact that Michael has been locked up since Jamie was born and has never even seen her, beginning to walk away as Loomis screams that he has seen six bodies between Haddonfield and Ridgemont and mentions the filling station that Michael blew up. Loomis continues that Michael has arrived to kill Jamie and anyone that gets in his way. Meeker tells another officer to check out the validity of Loomis' claims and Loomis interrupts him to say it is true, Meeker throwing his hands up and conceding it is true before asking what they can do to avoid a repeat of ten years ago.
Loomis answers that they can find Jamie, get her "someplace safe", and call the local TV station so they can replay a message to get people off the streets and behind locked doors. The other officer says they cannot get long distance and that the operator has told him the lines are down, causing Meeker to look at Loomis and decide to go with him to check on Jamie. Loomis and Meeker enter the Carruthers house armed and go into Jamie's bedroom, where Loomis picks up a picture from a box of photographs. Meeker comes over to Loomis and asks if he found something, Loomis replying that Michael has been there and Meeker asks him how he knows. The two then notice the corpse of family pet Sundae and after Meeker admits he is starting to get spooked, Loomis tells him that at least he is not alone. The two then descend down the house's staircase and go outside to get into Meeker's police car, driving around until they locate Jamie and Rachel Carruthers. Loomis and Meeker get out of the vehicle and Loomis instructs for them to get into the car. Loomis shuts the door on Jamie's side and notices what appears to be Michael standing still in a corner. Meeker asks Loomis if that is Michael, and asks him again after Loomis does not respond, Loomis answering that it is as he reaches for his revolver.
Meeker calls out Loomis' name as he spots another person with the same mask and attire of Michael, and Loomis looks over. A third Michael lookalike appears next to the car, and Loomis, convinced that Michael has developed an ability to make copies of himself, points his gun at one of the dopplegangers before the three reveal themselves as playing a prank on Meeker and run off. Loomis and Meeker leave Rachel and Jamie in Meeker's police car to enter the Haddonfield Police Station, where they discover the corpses of officers slaughted by Michael. Meeker says the officers would not have given up without a fight and Loomis retorts that they did not know what they were fighting. As Meeker discovers another corpse, he asks Loomis how can a man do this and Loomis responds that it is not a man, being grabbed by Meeker as the latter demands that Loomis tell him what they are dealing with. Loomis responds, "evil" and walks out of the station followed by Meeker.
As the two men exit, they are confronted by Earl Ford and a group from Ford's bar, who demand answers on the curfew. Meeker refuses to tell them and Loomis reveals that it was Michael Myers and furthers that he has come home to kill. After Ford states his intent to kill Michael as revenge for the 1978 murder spree, Meeker grabs Loomis, accusing him of having created a lynch mob. Loomis reminds Meeker that he no longer has a police force and removes Meeker's grip on him, stating that these men may be the only defense Meeker has. Meeker takes Loomis, Jamie, and Rachel back to his home, where Loomis asks Meeker for the location of the radio. Loomis stands over Meeker as he radios for aid from state troopers, and spots Rachel walking around, asking her if Jamie is alright. Loomis informs Deputy Logan of Meeker radioing for aid and estimates that they will be there soon.
Loomis says that it is not over yet and after being asked where he is going by Logan, Loomis states his intent to go to the Carruthers house since that is where Jamie lives and where Michael would go to find her. Logan tells Loomis to leave Michael to the state police and Loomis rebukes this by saying that they would not know how to stop him. Logan asks if knows and Loomis admits that possibly no one knows how to stop him and adds that he has to try before leaving. Meeker leaves the house to pursue the lynch mob and Michael kills everyone there except for Rachel and Jamie, the latter of whom left to run on her own after Rachel was rendered unconscious from falling. Loomis sees Jamie by herself and grabs her as he questions what she is doing outside by herself, Jamie saying that everyone is dead and that she just wants to go home.
Loomis tells her that she cannot, as he had just been to the Carruthers house and believes this to be the first place Michael would look for her. Loomis then asks her where the schoolhouse and she points to it, Loomis taking her hand and telling her that they would be safe there. Arriving in front of the building, Loomis covers Jamie as he shoots the lock off of the front door and they walk inside. The shot sets off the alarm and Loomis tells Jamie that they will hear sirens soon, confirming that they would be safe. Jamie asks him if he does not really believe that and Loomis admits that he does not, hugging her briefly before Michael appears behind the pair and grabs Loomis, throwing him through the glass door of an adjacent classroom. This allows Michael to briefly stalk Jamie without intervention until Rachel sprays him and removes Jamie from the building.
Loomis is later seen to have recovered as he witnesses Meeker, a few of the mob, and state police shoot Michael, sending him down an abandoned well, which they ignite and blow up, seeming to finally kill him. Loomis arrives at the Carruthers house and agrees with Meeker that it is over, Loomis adding that Michael is in hell where he belongs. Meeker says that Jamie and Rachel are not likely to forget and Loomis responds that the pair survived the ordeal and will also survive its memory. A short time later, Loomis hears a scream from upstairs and sees the horrific sight of Jamie after having just stabbed her stepmother, dressed in a clown costume similar to what Michael wore when he killed his sister as a child. Meeker stops Loomis just as he raises his gun to Jamie, and Loomis seems to go mad by the thought that the evil that drove her uncle has now possessed his niece.
One year later, Loomis is assigned to Jamie at the Haddonfield Children's Clinic. Aware that Michael is still alive, and discovering that Jamie is telepathically linked with him, Loomis constantly pressures her to inform him of Michael's whereabouts, but Jamie is too traumatized to tell him. When Michael returns he kills Rachel Carruthers and her friends one of which Loomis tried to save. Once Tina Williams dies, Jamie agrees to help out Loomis. The police and Loomis set a trap for Myers at his house, involving the young niece to sit at the dressing table in Judith Myers's old bedroom. After the police receive calls linking Myers to be at the clinic, they all leave, leaving Loomis, Jamie and deputy Charlie Bloch.
Bloch is ordered to take Jamie to the police station but he is stopped by Loomis who knows Michael will still come to the house. Loomis turns out to be right and Michael does arrive, and Loomis tries to reason with him, proposing that he fight his rage and redeem himself through a positive relationship with Jamie. Loomis' words seem to work at first, as Michael calmly listens to him and lowers his knife, but when Loomis reaches to take away Michael's knife, he slashes him across the abdomen and throws him through the banister in a frenzy. When Loomis awakens, he appears to turn on Jamie, grabbing her and shouting for Michael to take her, only to lure Michael into a trap; Loomis drops a metal link net over Michael, shoots him with a tranquilizer gun, and then violently beats him unconscious with a wooden plank. Dr. Loomis suffered a stroke immediately after attacking Myers. After that, he retires and moves to a quiet hut on the outskirts of Haddonfield. There he lives a solitary, almost hermit lifestyle, choosing not to interact with other people.
The Cult of Thorn
In 1995, the nightmare starts all over again. It is a cold and stormy night when someone knocks on Sam's door. It is Dr. Terence Wynn, his old colleague, who had come to persuade Loomis to return to Smith's Grove. Sam declines. While the two are arguing about that, they hear the voice of Jamie Lloyd on the radio. She is begging Dr. Loomis to help her.
It turns out that Jamie was impregnated by the same cult that kidnapped her in 1989; however, she succeeds in escaping after giving birth to a baby boy. She takes the child with her, and stops at a bus station to call Dr. Loomis. However, Michael tracks her down and kills her, but cannot find the baby.
Jamie has left her son in the bus stop bathroom. There, he is found by Tommy Doyle, the boy whom Laurie Strode was baby-sitting in 1978 who has become a deranged adult bent on destroying Michael Myers. He names the child Steven.
The following morning, Jamie's body is discovered, and Loomis is devastated. He had thought that the last of Michael's bloodline was killed that night, but after being approached by Tommy Doyle, who tells him about his discovery of the baby, Loomis knows he has to fight his nemesis one last time in order to save the infant. Tommy tells him to meet him at the campus rally that night to discuss what to do next.
That night, Loomis meets with Tommy, but their meeting is cut short as they discover the body of Barry Simms falling from a tree. They both knew that Michael is now in Haddonfield.
They return to Tommy's home to discover that the baby is missing as well as Kara Strode and her son, Danny. The Strodes eventually bang on the door, begging to be let in as Michael is chasing them. Tommy questions Loomis on who knew about the baby, who tells him that only they and Wynn knew about it. This is when they all hear a voice call out to Danny.
They walk into the living room where it is revealed that Dr. Terence Wynn, Sam's old colleague is actually the "Man in Black". Wynn, along with an old neighbor of the Myers family, placed the Thorn Curse on Michael years ago on the night he killed his sister, Judith. Loomis and Tommy are then drugged while Wynn takes Kara, Danny and Steven with him to Smith's Grove.
As soon as they recover, the duo travel to Smith's Grove where Loomis intends to deal with Wynn. He tells Tommy to stay put while he takes care of things. He finds Wynn in his office where Wynn reveals he wants to experiment on Jamie's baby to re-create Michael. Loomis is about to shoot Wynn, but he is knocked out by Wynn's henchmen. They leave Loomis while they go to Steven and Danny.
Loomis awakens and searches for Tommy and the others. He finds them running away from Michael and opens the gate for them. After they get into their car, Tommy asks Loomis to come with them, but he tells them he still has some things to finish up in the sanitarium. Once he goes inside, he finds Michael's mask but apparently no body and screams. The fate of both Loomis and Michael remains unclear.
Resigned to trying to reach Michael, Loomis has dedicated himself to stopping his evil. His extensive history with Michael makes him one of the few people always aware of and prepared for him. This often puts him at odds with the law enforcement and denizens of Haddonfield who doubt his claims. His obsession with putting an end to Michael's murder sprees can lead him to act in an aggressive manner toward others, such as threatening Terrence Gummell with a gun to get him to drive him to Haddonfield Hospital.
Loomis, at some point, developed a pessimism to the effectiveness of hurting or successfully killing Michael. After shooting Michael during Halloween 1978, and seeing that the latter had gotten up shortly thereafter, Loomis had an unsurprised expression. After shooting Michael multiple times at Haddonfield Hospital, he warned Terrence Gummell to stay away from Michael's seemingly comatose body and refused to believe that Michael was dead. Because Michael has survived in these instances, Loomis's pessimism is validated in being an informed skepticism that has come from his awareness of Michael's durability.
Although Loomis asserted that he had given up on Michael, he made multiple attempts to persuade him, such as when he offered his own life in exchange for Michael leaving Jamie and other Haddonfield residents alone and when he spoke to Michael about Jamie's ability to stop his rage upon Michael arriving at the Myers home. During this conversation, he calmly spoke to Michael about the latter's past and current emotions and reached for Michael's knife. Although this proved fruitless, as evidenced by his lack of drawing a weapon and having his own guard lowered while maintaining very little distance between them, Loomis genuinely believed there was a chance to reach Michael through talking. This contradiction only adds to the complexity of Loomis's view on the chances for a true rehabilitation of his former patient.
Despite their many differences, Loomis and Michael share a distinct high level of determination that causes them to push toward their polar opposite goals with a similar resistance to physical abuse. Just as Michael has survived being shot at repeatedly, burned alive, and beaten repeatedly, Loomis has survived being stabbed, burned alive, and being thrown through glass. Both men were shown to, in some cases, receive these injuries and return to their regular operations within a manner of hours, as Loomis recovered enough from being thrown through glass to where he was able to walk in less than a night and Michael recovered enough from being beaten repeatedly by Loomis to where he could walk in less than a night. They are both also willing to employ lethal methods to accomplish their mission, although Loomis would only do this to Michael while the latter regularly kills random people.
A key quality of Loomis' is his selflessness. His involvement in trying to put an end to Michael's various murder sprees is entirely out of concern for the welfare of others, as Michael has never targeted Loomis outside of whenever Loomis intervenes. When he tried to kill Michael at Haddonfield Hospital, he signaled for Laurie to leave the room and was willing to sacrifice himself if it meant killing Michael. When encountering Michael for the first time in a decade, as the latter was in pursuit of Laurie's daughter, Jamie, Loomis tried to offer himself as a victim in the place of the residents of Haddonfield. After being knocked out by Terence Wynn's henchmen, Loomis was given the opportunity to flee, but instead came to the aid of Kara, Tommy, Danny and Steven. Loomis viewed his own life as lesser than the purpose of stopping Michael from hurting innocent people.
While Jamie was admitted to Haddonfield Children's Clinic, and after Loomis became aware of her telepathic bond with Michael, he tried to pressure Jamie to reveal what she knew about Michael. This earned him repudiation from Nurse Patsey, but his serious treatment of her telepathic bond with Michael made him the only person who took Jamie's visions as more than just nightmares. This also caused him to be attentive to Jamie in ways that others were not, as he called Rachel upon Jamie's request and demanded Deputies Nick Ross and Tom Farrah prevent Tina Williams from leaving the clinic after Jamie begged for her to stay. This demonstrated Loomis wanted to both ease Jamie's concerns while having her use her telepathic link to prevent Michael from killing more people and Loomis's obsession with stopping Michael made him believe fully in the supernatural.
Despite the extreme lengths he would go to in order to confront Michael, Loomis seldom operated alone, acquiring the aid of law enforcement both during the 1978 murder sprees and when Michael became active again ten years later. Loomis evidently believed in the strength of numbers as he knew Michael was most successful when cornering individuals rather than fighting groups. While Loomis was willing to confront Michael alone, and would do so when either making pleas to him or when put in a particular circumstance where Michael had dispatched of officers, his constant push for the assistance of others highlights his particular knowledge on Michael's modus operandi.
Loomis usually has a firearm on hand during his encounters with Michael, which shows his preparedness. This contrasts him with most of the people Michael meets, who are oftentimes unarmed and caught off-guard in being confronted by Michael, and gives him a similarity with law enforcement.
Loomis also values the feelings of others. When he spoke to Laurie after shooting Michael at Haddonfield Hospital, he apologized for leaving her side and asked if she was alright. After encountering Jamie while the latter was running from Michael, he confirmed that they would be safe after hearing police sirens, not because he actually believed this, but due to wanting Jamie to be less afraid of Michael. Loomis also embraced Jamie before and after this exchange. Whether he was calling Rachel to ensure her safety after Jamie sensed she was in danger or trying to prevent Tina from leaving Jamie's clinic after a similar premonition, even pleading with Tina to spend the night with Jamie, many of Loomis' activities during the period Jamie stayed at Haddonfield Children's Clinic were done out of concern for Jamie's feelings. At the root of Loomis' obsession with stopping Michael is the concern for others, whether they are well or injured, and in the event they encounter Michael, whether they live or die.
- This is the only version of Loomis to not have been confirmed dead, although his fate is left unknown at the end of The Curse of Michael Myers.
- Between Halloween II and Halloween 5: The Revenge of Michael Myers, Loomis is assaulted by Michael in every film they appear in.
- Loomis and Michael are the only characters to appear in every film in this timeline.
- After Halloween, Loomis lays on the ground in every film he appears in. Loomis collapses to the floor after being stabbed by Michael in Halloween 2, he jumps to the ground to avoid the explosion at the filling station in Halloween 4, he falls on top of Michael after having a stroke in Halloween 5, and he falls when struck behind by Wynn's men in Halloween: The Curse of Michael Myers.
- Loomis jump scares Jamie twice. In the fourth film, Looims does so when he comes on the side of her after she flees Sheriff Meeker's home to get away from Michael. In the fifth film, Loomis jump scares Jamie and Billy Hill when he comes behind the two after they flee from Michael, following Tina sacrificing herself to protect Jamie.
- Loomis's stroke in Halloween 5: The Revenge of Michael Myers was written with the intent of killing off the character as Donald Pleasance wanted to retire from the franchise. Had this happened, Loomis would have been the only character to die in the film from natural causes as opposed to being murdered.
- Loomis is shown to be equipped with a firearm in each of his appearances.
- Of the four films featuring Loomis wearing his trademark trench coat, Halloween 5 is the only one where he does not also wear a brown suit.
- Along with Tommy Doyle, Loomis is one of two characters to beat Michael repeatedly with a blunt object in this timeline.
- The Curse of Michael Myers is the only film in which Loomis does not wear his trademark trench coat.
- Loomis has the last spoken line in Halloween, Halloween 4, and Halloween: The Curse of Michael Myers.
- When Loomis raises his gun to shoot Jamie at the end of Halloween 4, it is the only time in all five films that Loomis tried to shoot someone that was not Michael or that he thought was Michael.
- Loomis is the only character to interact with Jackson P. Sayer in Halloween 4.
- Along with Brady, Loomis is one of two characters to fire at Michael and miss in Halloween 4.
- Along with Michael, and Laurie Strode from the H20 Timeline, Loomis is one of three characters to retain physical scars from Halloween 1978 that are carried over to subsequent films: both he and Michael have burn injuries, while said incarnation of Laurie has a scar on her shoulder from being attacked by Michael after discovering her friends' bodies.
- Halloween: The Curse of Michael Myers is the only film in which Loomis does not partner with law enforcement to end Michael's killing spree.
- The Curse of Michael Myers is the only film to depict Loomis at his place of residence.
- Terence Wynn is the only character to refer to Loomis by his first name, calling him "Sam" during their interactions in the first and sixth films.
- In the original Producer's Cut of The Curse of Michael Myers, the ending has Dr. Loomis becoming the Cult of Thorn's new leader by force of having the mark passed on to him, and the film ended with the same scream presented as originally shot, instead of as a background noise. This asserts Loomis' fate as alive, but better off dead, while Michael's fate remains unaccounted for. It is possible that the treatment written by Daniel Ferrands for the proposed Michael Myers: Lord of the Dead was cancelled due to Pleasence's death.
