Characters that appear in the only anthology film for Halloween.
The protagonist of the only anthology film, Dr. Challis is a doctor who has an estranged relationship with his ex-wife and two children. He stumbles upon a greater conspiracy on October 23rd involving a mysterious television ad and the Silver Shamrock Novelties company.
- Action Survivor: He manages to be quite resourceful in dealing with Conal Cochran's cronies despite being just a doctor.
- Awful Wedded Life: It's pretty clear than Challis and his ex-wife do not get along.
- The Hero: Of the third film.
- MayDecember Romance: Falls in love with Ellie, who is a good two decades younger than him.
The female lead of the only anthology film, whose father was murdered by a mysterious man over a connection to masks made by Silver Shamrock Novelties. She joins Dr. Challis in his investigation and develops an attraction to him.
- And Then John Was a Zombie: Dr. Challis discovers she was replaced by one of Cochran's androids after he escapes his lair.
- Ms. Fanservice: She spends a scene in a short and seductive black nightgown. Before that she had a Shower Scene followed by her being covered by a Modesty Towel.
- MayDecember Romance: Is a good two decades younger than Dr. Challis.
- Uncertain Doom: Is replaced with one of Cochran's androids when she and Challis are captured, leaving her true whereabouts unknown.
The Big Bad of the only anthology film, who runs the Silver Shamrock Novelties company and plans on killing children across America using special masks.
- Bad Boss: How does he reward his best salesman? By locking him and his wife and child in a room to be the first test subjects, causing his son's head to rot.
- The Bad Guy Wins: The film implies Dr. Challis didn't manage to get his commercial pulled from every television station, so a large number of children are still implied to have died.
- Big Bad: Of the third film.
- Contrasting Sequel Antagonist: Michael Myers is a young, strong man, while Cochran is an elderly man with little physical power. Michael is a mute mental patient with no social skills while Cochran is a very charismatic businessman and well-liked among the townspeople. Michael is a brutal unstoppable killer, and Cochran's android enforcers do all of the killing for him. Perhaps most interestingly, the Shape is defined by the iconic mask he wears, while Silver Shamrock uses masks as weapons to kill their unlucky victims.
- Corrupt Corporate Executive: Runs the Silver Shamrock Novelties company as a front for his plan to kill children.
- Evil Old Folks: Is quite an old fellow and very evil.
- Evil Sounds Deep: When his evil nature is exposed he talks in a quite deep and cold voice.
- Face Death with Dignity: Maybe. When Challis kills his employees, Cochran gives a slow cap and smiles before he appears to disintegrate, although given his supernatural plot, it's unknown if he died.
- Graceful Loser: Smiles and gives a golf clap when he appears to lose, but it's possible it's because he had one more trick up his sleeve.
- It Amused Me: He describes his evil plan as a great big joke on the children.
- Non-Action Big Bad: He clearly knows magic, but he almost entirely relies on his robotic henchmen to drive the plot for him.
- Not-So-Well-Intentioned Extremist: According to Cochran, his plan is intended as a mass Human Sacrifice to ancient pagan gods. This could be seen as a well-intentioned plan - especially since the existence of such deities is strongly vindicated by the fact that Cochran's Stonehenge-powered ritual magic actually works. None of this changes the fact that he is a horrible person who has absolutely no remorse over the massacre and in fact seems to consider it amusing.
- Offscreen Villain Dark Matter: It's never really explained just where this guy has the resources for fully functioning robot minions or the means to steal whole landmarks. He even humorously lampshades it when he shows his steal to Challis.
- Oh, Crap!: It's possible he wasn't expecting the stonehenge to backfire, as he has a look of sheer shock on his face when it starts to glow ominously. Although he regains calm and gives a gentleman's clap before he's disintegrated by the ensuing beam.
- The Sociopath: Arguably as horrifying as Michael Myers with his evil plan to murder millions of children.
- Uncertain Doom: He appears to disintegrate at the end of the film, but the novelization implies he survived.
- Would Hurt a Child: His plan revolves around the murder of millions of children across the United States.
The silent, intimidating enforcers of Silver Shamrock Novelties, and Cochran's muscle throughout the film.
- Berserk Button: Badmouthing Cochran, apparently. Whether this is due to Cochran ordering them to, or they're just that fanatically loyal to him is unclear.
- Dressed to Kill: Like their master, they're typically seen in snazzy business suits as they go about killing.
- Glass Cannon: For what deadly killers they are, they're still walking clockwork machines and thus don't share Michael Myers's supreme durability. Dr. Challis takes down a good many of them.
- The Heavy: Cochran is the one with the plan, but these guys are the ones eliminating all potential threats to him and constructing Silver Shamrock's lethal masks, thus doing most of the heavy lifting.
- Helping Hands: The Ellie-Bot shows the ability to continue controlling it's limbs after Dr. Challis severs them.
- Killer Robot: They're designed as unfeeling assasins, and they carry their job out with lethal precision.
- Machine Blood: They have yellow oil inside of them.
- Magitek: As the automaton creations of a warlock, they both constitute and utilize this, mass producing deadly Halloween masks that transform the wearers into vessels for vermin, reptiles, and insects.
- Mecha-Mooks: A way more lethal type of this.
- Ninja Pirate Zombie Robot: An organization of android-warlock toy-makers.
- Ridiculously Human Robots: Mostly avoided since they don't display much agency, but oddly one of them is shown sneezing. The novelization takes it a step further with the Ellie droid who refers to Cochran as her "father" and displays the personality of a small child. The implications are quite disturbing.
- Silent Antagonist: Much like Myers himself, although one of them does speak to Cochran when reporting about Challis' escape.
- Super Strength: They're built well enough to rip a man's head off his shoulders or crush another's nose with their fingers.
- Suspiciously Similar Substitute: To Michael Myers, being silent unfeeling killers who only appear human and seek to cause carnage on Halloween. Although they aren't quite as strong or tough.
