Some possible reasons why Michael Myers hasn't talked again since the murder of his sister is that it's part of the catatonia he tricked everyone into thinking he had, while others, based on the events of Halloween Kills, suggest he is still in shock after what happened in 1963, and he's still that little boy who ...
For instance, The Cult of Thorn storyline from the original movie track implies that Michael Myers isn't human. At six years old, he became a pawn, and with the first sacrifice of Judith, his soul got infected by the murderous being worshiped by the cult. As such, he might not be able to communicate like a human does.
1) Michael Myers always wears his mask — and he never, ever speaks. You rarely see him without his mask in any of the films. The Shatner masks have become the stuff of horror film legend. As for his voice, you only hear him speak in one film in which his childhood is explored — before he became a monster.
His voice would be cold and emotionless, sending shivers down the spines of anyone who heard it. Of course, it's unlikely that Michael Myers will ever speak in the movies. His silence is part of what makes him so terrifying.
As an adult, he never speaks, though perhaps this is because we've never witnessed interactions with someone he trusts. The reason it's a “maybe” check is because selective mutism can also be a response to trauma, which Jason most certainly experienced after witnessing the death of his mother.
Diagnosing Michael Myers - Why Doesn't He Speak? (Halloween 1978 Analysis)
What is Michael Myers' weakness?
Another weakness pointed out by viewers is Michael Myers' iconic mask, as every time he has been unmasked he stops killing, even though he had his victim in front and completely helpless.
However, he somehow popped up in one piece back at Crystal Lake at the start of Part IX. Then he was blown to bits, although his heart continued to beat. The living heart allowed him to possess living humans. Then we learn Jason can be born again through another Voorhees, and that only a Voorhees can kill him forever.
Jamie gets him to take off his mask and show his face to her, and even sheds a tear before falling into a murderous frenzy when she tries to touch him. Speaking with HalloweenMovies, director Dominique Othenin-Girard stated Michael cries because "Again, to humanize him, to give him a tear.
Loomis' vagaries in the original Halloween movie: Michael Myers isn't a man, but pure evil in human form. In the coda of Halloween Kills, Michael lies prone after being viciously beaten, before regenerating in front of the Haddonfield mob.
Michael does not speak in the films; the first time audiences ever hear his voice is in the 2007 remake. Michael speaks as a child during the beginning of the film, but while in Smith's Grove he stops talking completely.
For starters, one cause as to why Michael never runs may be due to his mind still being present on the night that he killed his sister. If so, that would mean Michael never mentally matured, and he won't chase his victims because the child version of Michael still believes he wouldn't catch them if he ran.
Myers is still a human despite the near-supernatural powers they give him, he is a "bogeyman" figure but ultimately he is still meant to be a human psychopath - this mean he will feel pain like any other living creature does, he simply masks it or he is in a state of psychosis where his mind simply doesn't register ...
The masks in horror films help dehumanize the villains and make them scarier, as well as provide an instant hook for the advertisements. Most of the slashers also had actual reasons to hide their faces, whether it was to disguise a deformity or hide their identity if and when the police came calling.
Michael however is not without his fears as it indicated that he wears his mask to hide his face and emotions due to the fact Michael's face is seen to be normal looking and rather handsome, and since one of the sources of Michael's power is through the fear he inflicts on others, Michael could be afraid of losing that ...
So, in 1963, during Samhain, he got cursed by The Cult of Thorn. As part of this curse, Michael must wipe out his entire bloodline to keep the cult alive. It starts with Judith Myers, and then his parents die, so the target shifts to young Laurie Strode.
Michael Myers not running after his victims because he prefers the thrill over the kill makes him scarier, because he can go after anyone at any moment, and he moves slowly on purpose just so the victim gets more and more scared.
While Michael has proven time and again that he can survive nearly anything, he doesn't stand a chance against Jason. Jason's immense strength and ability to keep killing no matter the circumstances show that he can withstand a full-on assault from Michael.
It's mentioned in the first Halloween movie that Michael Myers didn't say a single word during his time at Smith's Grove, so he's not mute as he did talk before the murder of Judith. Michael Myers, then, has chosen not to speak again, though why exactly is what continues to be debated among viewers.
Michael Myers Became Obsessed With Laurie After He First Saw Her In Halloween. In Carpenter's movie, a reason for Michael Myers killing his sister wasn't given, and he was simply described as the embodiment of evil – so if he killed his sister without an apparent motive, he could kill pretty much anyone.
Dr. Tobia believes that Myers suffers from Conversion Disorder, a mental illness “characterized by loss of sensory and/or motor function,” which explains why Myers never says “I'm back, bozos!,” or utters anything else for that matter.
Jason is notably furious when the deception is revealed. Pamela (played by Nana Visitor) has a minor presence in the 2009 Friday the 13th reboot. The opening scene shows her chasing a young girl, presumably Alice, at the end of her Camp Crystal Lake killing spree, who ultimately decapitates Pamela with her own machete.
Likewise, director Tom McLoughlin chose not to have Jason harm any of the children he encounters in Jason Lives, stating that Jason would not kill a child, out of a sympathy for the plight of children generated by his own death as a child.
Apparently, after Jason's initial death from drowning, his mother found a book that could resurrect him. Thus, when he came back, he had otherworldly, super-powered abilities.
