Michael Myers (original)

"I met him, fifteen years ago. I was told there was nothing left. No reason, no conscience, no understanding; even the most rudimentary sense of life or death, good or evil, right or wrong. I met this 6-year-old child with this blank, pale, emotionless face, and the blackest eyes; the devil's eyes. I spent eight years trying to reach him, and then another seven trying to keep him locked up because I realized what was living behind that boy's eyes was purely and simply… evil."

- Dr. Samuel Loomis contemplating his former patient: Michael Myers. "Look, let me make things nice and sparkling clear! Michael Myers is f-cking dead! Now do you brain dead gossip mongers want me to spell it out for you? D-E-A-D!"

- Samuel Loomis claiming that Michael Myers is dead in Halloween II.

Michael Audrey Myers (born October 19, 1957), also known as The Shape or The Bogeyman, is a legendary serial killer and the main antagonist of the 1978 classic horror film Halloween, and its many sequels (except for Halloween III: Season of the Witch) along with its modern remakes.

Timelines
His continuity is complicated due to there being four diverging timelines:

4-6 Timeline

 * Halloween (1978)
 * Halloween II (1981)
 * Halloween 4: The Return of Michael Myers
 * Halloween 5: The Revenge of Michael Myers
 * Halloween: The Curse of Michael Myers

H20 Timeline

 * Halloween (1978)
 * Halloween II (1981)
 * Halloween H20: 20 Years Later
 * Halloween: Ressurection

Final Timeline

 * Halloween (1978)
 * Halloween (2018)

Portrayals

 * He was portrayed by George P. Wilbur in the 4th and 6th film.
 * Don Shanks portrayed Myers in the 5th entry

Personality
Michael Myers is an unusually persistent, but very human serial killer in the H2O/Resurrection and 2018 timelines, with only the 4-6 and alternate 4-6 timelines as a genuine supernatural killer. Michael Myers was a little 6-year-old boy who murdered his older sister Judith on Halloween night.

In the 4-6 timeline, Michael's actual personality becomes vague and conflates depending on the version. In the fifth film, Michael has an odd moment of humanity when he takes his mask off for Jamie, and shed a tear before resuming his rage. The difference is in the Producers cut where Michael is explicitly shown as a puppet bound by a supernatural curse, while the theatrical cut the curse is a theory brought up but never fully explored with Michael's rage being what drives him. In the theatrical cut, Jamie seemingly reaches out to him again, only for Michael to push her down harder onto the blades after seeming to reach back to her.

For 15 years, he was kept in Smith's Grove Sanitarium, under the care of Dr. Samuel Loomis, who understood that he was actually pure evil, intending to put an end to peace.

On October 30, 1978, Michael escaped to seek vengeance and began his new intention of putting an end to his family and all the peace in Haddonfield, Illinois while being pursued by Loomis, who intends to stop him.

Michael seems to like playing games on his victims by sadistically stalking and terrifying them before brutally killing them. A perfect example of this is when Michael puts a ghost costume on along with glasses, making Lynda believe it's her boyfriend Bob. When her back is turned to make a phone call, he strangles her to death with the telephone line.

The original Michael Myers has killed (at least) 81 people, and his remake has killed 46 (if you count the kills of his dream in Halloween II).

Goals and Motivations
While it is widely accepted that Michael Myers's ultimate goal is to kill his own family, due to multiple changes in canon and continuity, confirming his ultimate goals and motivations to murder is nearly impossible. According to his nemesis, Dr. Samuel Loomis, the once innocent boy just spontaneously committed murder apparently for no actual reason except that he is nothing more than pure evil. Indeed nearly none of his murders have ever led to anything remotely self-serving. However, despite his complete lack of reasoning, many of his actions exhibit distinct patterns and recurring traits, which may provide hints to understand his psychosis.

Michael's most distinct characteristics are his preference to always be wearing a mask, his absolute inability (or refusal) to speak, and his murders, which all happen on Halloween night, suggesting that the night itself, or the sinister aspects of the holiday, play a part in his motivation. His murderous tendencies could be his own idea of how to celebrate Halloween.

In his first murder spree as an adult, he exhibited an absolutely twisted sense of mischief, which he himself shows no signs of amusement for. He dresses up in costumes and masks to approach unwitting victims, occasionally murders his victims in elaborate and inventive ways, and would sometimes display his victims' corpses in ritual-like presentations, like placing his sister's tombstone over the recently killed Lynda. In the "Thorn" timeline (movies 4-6), he decorated an entire attic like a gallery, complete with candles, his victims on display, and a coffin reserved for his own niece.

Michael also appears to harbor some obsession with his sister Judith, his first victim from childhood. While he does kill very much all men and women who are unfortunate enough to be alone with him, his most seemingly "chosen" targets have all been women and girls who bear some (real or perceived) relation or resemblance to Judith. After killing Lynda, who was not at all a relative to the Myers family, he left her body displayed on a bed below his sister's stolen tombstone. In the comic book, Halloween: Nightdance, Michael stalked a girl named Lisa Thomas and buried her naked and alive in a coffin below a wooden cross bearing the name "Judith Myers". Judith's relationship with her boyfriend, as well as Lynda's similar relationship with hers, and the sexual nature of Lisa's burial, indicate that Michael may be motivated by a very morbid fetish, or a deep hatred for sexually active girls.

But most famously, his ultimate target appeared to be Laurie Strode, who was originally his last sister, making it his most widely assumed goal to kill his own family. Despite that, his choice of targeted relatives still appeared somewhat inconsistent. Right after murdering his sister Judith, he was discovered by his parents, showing no motivation to kill them as well.

In the "Thorn" timeline, Laurie died during Michael's absence, leaving behind her daughter, Jamie Lloyd. As his niece and last surviving family member, murdering Jamie became his next goal. It is revealed that Michael's reason for targeting his own family, as well as the source of his supernatural strength, was a curse placed on him by the Thorn Cult. The curse of Thorn tasks the bearer to sacrifice his/her own family on Halloween night to spare the community from death and natural disasters. Michael is the latest bearer of the curse, with his niece his next sacrifice. It should be noted the curse is explicit only in the "Producers Cut" where Michael is depicted as a supernaturally bound slave to the cult and curse. In the theatrical cut, the curse is a theory never fully explored with Michael being driven by rage, and even Terrence Wynn describing him as pure evil.

However, in the separate "H2O" timeline, Michael's target is still his sister, Laurie Strode. He pursued her until he finally killed her, apparently completing his life mission. During which, Michael was not as persistent against Laurie's son John, who was also Michael's nephew, but rather attacked him primarily to get to Laurie. Because this timeline does not share continuity with the "Thorn" timeline, Michael's terrorism against his own family once again remains unexplained.

Yet one final time, all aforementioned sequels have been abandoned. Laurie Strode and Michael Myers no longer have any blood ties. Despite that, Michael's murder of his sister, Judith, remains true, and so were his initial attacks on Halloween night that traumatized Laurie, and making it her life goal to finally defeat the Boogeyman in a showdown she believed was coming.

Once again, the closest thing to an explanation for Michael's motivation is Dr. Loomis's unsatisfying conclusion that the boy who killed his sister was "purely and simply evil".
