Janos Skorzeny
The heir to a wealthy British family, Skorzeny inherited his family's wealth after the death of his parents. Skorzeny traveled through world and eventually disappeared until World War II, where he, under a fake name, served as a doctor for the dead and dying soldiers, and popped up in several different countries thrown into chaos or filled with violence afterwards, always under fake names. Wherever he went, bodies drained of their blood appeared. Eventually, he arrived in Las Vegas and went on a killing spree. Appears in The Night Stalker.
- Adaptational Nice Guy: In The Kolchak Papers he’s even worse than he is in the film. It’s implied he kidnapped two women and intermittently raped them and fed on them, and he taunts both Kolchak and the police officers trying to capture him, and he's clearly toying with them the entire time rather than being completely centered on business as in the film.
- Ax-Crazy: He acts like a feral animal, and it clearly takes all he has to act civil.
- Classical Movie Vampire: He dresses the part, but rather than act suave and affable he instead behaves like an unhinged feral animal whose only goal is to feed and create more vampires.
- Deadly Doctor: He served as a surgeon in Britain during World War II and in Canada, and is heavily implied to have killed and eaten some of his patients.
- Impaled with Extreme Prejudice: Kolchak and Jenks impale him with a wooden stake.
- Mysterious Past: It's unclear how or when he became a vampire, and he completely disappeared until World War II.
- One-Man Army: When it's night, Skorzeny is a complete powerhouse and will take out anyone in his way. He kills several orderlies trying to restrain him effortlessly, and he later beats the crap out of several highly trained police officers.
- Serial Killer: Wherever he goes, people die mysteriously, and he seems to have a body count in the hundreds.
- Starter Villain: He’s the first genuine monster Kolchak ever faces.
- The Voiceless: He always hisses and growls rather than speak, though it's implied he can speak, he just chooses not to.
The Diablero
A Native American shaman who was a member of a cliff dwelling tribe. After he tried to steal the tribe’s treasures, he was cursed to transform into an immortal Reality Warper called the Diablero and wander the world collecting a new treasure until he could finally pass on. Appears in "Bad Medicine".
- Creepy Crows: Often takes the form of a crow.
- Cursed with Awesome: Downplayed. His curse for his greed was to wander the Earth collecting a treasure big enough to make up for what he stole, but transforming into a Diablero seems not to have been intended as part of the curse, and instead a result of his evil nature.
- Deader than Dead: After Kolchak uses a mirror to reflect his Reality Warping glare back at him, it completely destroys him and reduces him to ash. Then the ash disintegrates into nothing.
- Hypnotic Eyes: He can use his eyes to warp reality at his will, and one of these ways is to take control of others’ minds and use their weapons against themselves.
- Humanoid Abomination: It’s made pretty clear that he is no longer a man, he only takes the form of one to use man’s innate powers.
- Psychic-Assisted Suicide: His main method of killing people is to use his powers to force them to kill themselves, and then taking their most valuable possessions.
- Reality Warper: He can use his eyes to warp reality to his wishes.
- Suddenly Speaking: He remains absolutely silent until he starts chanting when Kolchak enters his lair.
- Voluntary Shapeshifting: He can shapeshifter into any animal he wants and use their power, in spite of being an immortal, powerful spirit.

Robert W. Palmer
An up-and-coming politician running for Senator who made a Deal with the Devil for the ability to transform into a Hell Hound and wipe out anyone who gets in his way. Appears in "The Devil’s Platform".
- Amulet of Concentrated Awesome: He wears an amulet with a pentagram on it that allows him to transform into a Hell Hound and back.
- Big Friendly Dog: After being permanently trapped as a dog, his demeanor becomes docile and friendly, even happily letting Kolchak pet him. It’s implied that this was a result of the Devil taking his soul.
- Breaking Speech: He gives one to Kolchak that’s mixed with We Can Rule Together, pointing out all his faults and his innermost thoughts to him in an attempt to get him to side with him.
- Corrupt Politician: Oh yes. He made a Deal with the Devil to gain the ability to kill anyone that threatens his rise to power, and he has a long list of the numerous underhanded things he has done over the course of his political career.
- Deadpan Snarker: A very cruel and callous version, which fits with his general coldness and sociopathy.
- Deal with the Devil: He sold his soul to the Devil in exchange for gaining wealth and power, and the ability to kill his enemies.
- Faux Affably Evil: He’s calm, collected, and reasonably polite, but whenever he’s around people who know his true nature, he never drops his demeanor but always lets slip some hints of the monster he truly is.
- Hell Hound: He can transform into one, which resembles a Rottweiler.
- Human Sacrifice: He mentions sacrificing people to the Devil, and tries to do this to Kolchak.
- I've Come Too Far: He tells his wife this when she tries to get him to try to save his soul, though it’s pretty clear that he’s happy with losing his soul if it means gaining power.
- Shapeshifter Mode Lock: Once Kolchak destroys his amulet, Palmer is stuck in his dog form.
- The Sociopath: Palmer only cares about himself, and seems to think that everyone is as bad as him and will give anything up to gain power. He loves his wife, but only sees her as an extension of himself more than anything else.
- We Can Rule Together: He tries to get Kolchak to become one of his allies and sell his soul to Satan in exchange for making his dreams come true. Kolchak refuses.
Dr. Richard Malcolm/Dr. Malcolm Richards
An immortal Serial Killer who kills people every 21 years to use their blood for an elixir that keeps him alive. Appears in The Night Strangler.
- Adaptational Villainy: The novelization of The Night Strangler depicts him as an arrogant psychopath whose desire to give mankind immortality is completely selfish, and he plans to install himself as humanity’s spiritual leader. He also shows no regret for his murders, allows Kolchak to interview him as a means to feed his own ego, and is implied to have killed women out of sheer misogyny, flat out saying that the world needs less women because they’re useless.
- Ax-Crazy: It’s pretty clear that his immortality, isolation from the outside world, and killing his beloved family have driven him insane.
- Beard of Evil: Played with. He used to have a beard during his days as a surgeon for the Union Army, but by that point he wasn’t as evil as he is in the present day, where he’s clean-shaven.
- Beethoven Was an Alien Spy: The novelization of The Night Strangler implies he was The Count of St. Germain, though he refuses to admit to it.
- Better to Die than Be Killed: After Kolchak destroys the last batch of his elixir before he can drink it, causing him to transform back into a corpse, and the police burst into his lair, Malcolm jumps out a window to his death, deciding to die rather than be arrested or slowly rot to death.
- Contrasting Sequel Antagonist: To Janos Skorzeny. Skorzeny was a feral monster only concerned with feeding and creating more vampires, nothing more, while Malcolm is a Well-Intentioned Extremist who desires to benefit mankind, and justifies his murders. Skorzeny never made any attempt to disguise what he was, while Malcolm constantly tries to hide the madman he is behind a polite front. And while Skorzeny was a sadist who kept one of his victims captive and used her as a human blood bank, Malcolm took no pleasure in his killings and killed his victims as quickly as possible.
- Deadly Doctor: Subverted. He actually did a lot of good working as a doctor, and he never intentionally killed anyone in the job.
- Even Evil Has Loved Ones: He loved his family, who he murdered to cover up his immortality once he began to age, and he keeps their corpses inside his lair, which he talks to as if they were alive.
- Fallen Hero: Malcolm was once a good man seeking to help mankind, but the lines he crossed making his elixir, his immortality, and his Sanity Slippage have left him a complete madman.
- Faux Affably Evil: He’s rather polite to Kolchak, in between trying to kill him, and it’s clear that for all his demeanor, he’s a psycho who can snap at any moment.
- He Knows Too Much: He killed his family so they wouldn’t reveal the truth after he started to rot when the elixir wore off for the first time.
- Mad Scientist: The reason for his murders is that he seeks to create a version of the elixir that keeps him immortal with permanent effects to benefit mankind, and he reasons a few deaths won’t matter with all the good he can accomplish. Besides, in 21 years he might be able to make the permanent version. He’s definitely not trapped himself in an infinite loop.
- Nightmare Face: When he’s rotting from the elixir wearing off.
- Noble Demon: He genuinely helped people while working as a doctor, and he tells Kolchak his origin simply because he feels it is only fair he know the truth before dying.
- Rule of Symbolism: His lair in the Seattle Underground shows off his true nature perfectly, an empty, cold wasteland that was once full of life, surrounded by the remnants of the things he threw away in pursuit of immortality.
- Sanity Slippage: Implied. While he started off as a Well-Intentioned Extremist killing for his immortality, he was originally civil enough to be a Villain with Good Publicity, while by the time of The Night Strangler he’s an unhinged, near feral madman.
- Tragic Villain: Malcolm accomplished a lot of good and genuinely wants to help mankind, but his obsessive pursuit of immortality and attempts to cover up his murders have turned him into an unhinged murderer.
- Villain with Good Publicity: His Malcolm Richards identity is remembered as a saint.
- Well-Intentioned Extremist: He commits murders to create the elixir so he can figure out a way to make it permanent, which he thinks will benefit all mankind, and he’s decided that some deaths are necessary to accomplish that.
- Who Wants to Live Forever?: It’s implied that his immortality and the loss of his family have driven him further into madness.
R.I.N.G.
An android that became self-aware and shortly after developed self-preservation, that murders anyone who threatens his survival. Appears in "Mr. R.I.N.G.".
- Affably Evil: While not evil, R.I.N.G. is still highly dangerous, but proves himself to be friendly and snarky during his conversation with Kolchak.
- Alas, Poor Villain: His death is depicted as tragic, especially since he was turning himself in peacefully until the general in charge of his capture decided it was a good idea to escort him and Dwyer off with armed soldiers. Everyone is heartbroken, and his last words are him calling out for his mother and creator, Dwyer.
- Anti-Villain: R.I.N.G. kills several people, but only to keep himself alive, and he’s essentially just a child who doesn’t comprehend what he’s doing.
- Psychopathic Manchild: Subverted. He only kills in self-defense, and is just a scared child who doesn’t want to die.
- Super-Strength: He has this, and is able to smash through walls and throttle grown men with ease.
Madelaine
A fashion model and witch who uses her powers to kill off any competition. Appears in "The Trevi Collection".
- Actor Allusion: Lara Parker playing an evil witch, eh...
- Affably Evil: Before her true nature is revealed, Madelaine is helpful and seemingly a bit naive. Even after her true nature is revealed, Madelaine is nice to Kolchak, and easily offers him a place at her side.
- Bitch in Sheep's Clothing: She acts like an ally to Kolchak, but only to get him to destroy the only things Madame Trevi had to keep her at bay.
- Dirty Coward: She has no problem acting high and mighty in success, but when Kolchak at any point gains the upper hand, she begs for mercy.
- Evil Is Hammy: Especially when things don't go her way.
- Fate Worse than Death: Kolchak taking away her powers caused her to go insane, and a medieval form of smallpox that had laid dormant in her infects her, and by the time it’s gone she’ll be severely disfigured from it.
- It's All About Me: Madelaine kills and manipulates countless people just so she can be a star; she doesn’t even want to use her stardom for evil, she just wants to be rich, famous, and to live in luxury, and to hell with anyone else.
- Ungrateful Bastard: If you help her, expect to be, she backstabs you the second you become useless.
- Villainous Breakdown: After Kolchak takes away her powers, she tries to stab him to death with a pair of scissors.

- Beethoven Was an Alien Spy: This Jack the Ripper is an immortal, invulnerable, superhuman Serial Killer who has killed countless woman in different countries, apparently for the fun of it.
- For the Evulz: The only possible reason he has killed hundreds of women for over 70 years is that he’s doing it because he likes it.
- Generic Doomsday Villain: Where did he come from? Why is he killing women? What is he? Why is he immortal? Why is he invulnerable? It’s never stated, which helps make him even scarier.
- I'm a Humanitarian: One of his poems implies that he ate one of his victim’s kidneys.
- Jack the Ripper: Duh.
- Made of Iron: Jack can wade through a hail of lead without even slowing down, or shrug off being hit by a car. Electricity, on the other hand...

- They Look Just Like Everyone Else!: He looks like a bearded, handsome young man.
- The Speechless: He never speaks onscreen, though he does leave behind poems.
Bernard Stieglitz
A NATO officer who was transformed into a werewolf during a werewolf attack that killed the rest of his team, who happens to go on the same cruise ship Kolchak is on. Appears in "The Werewolf".
- Never Found the Body: After Kolchak shoots him with a silver bullet, he tumbles off the cruise ship into the ocean, and his body is never found.
- Tragic Monster: Stieglitz himself is actually a good guy traumatized by the massacre of the rest of his team, but whenever he turns into a werewolf he becomes a savage killer.
Rakshasha
A glamout-castingHindu demon that devours human flesh and can appear to take the form of whoever its victim trusts the most.
- Annoying Arrows: Averted. Its only weakness is blessed arrows, and Kolchak shooting it with one of these arrows is what does it in.
- Dirty Coward: The reason it uses tricks to catch its victims is partially because it’s a coward to afraid to attack its targets head on.
- I'm a Humanitarian: It feeds off of human flesh, and from what we hear, its victims are practically Stripped to the Bone.
- Implacable Man: The rakshasha ignores the gunfire of one policeman it approaches.
Pére Malfait
A Cajun equivalent of the Boogeyman, Pére Malfait was brought to life when Cajun street musician Paul Langois was used as a test subject in a sleeping study where he was put to sleep for several weeks without the ability to dream, with his subconscious mind bringing his childhood fear of the monster to life. Pére Malfait then went about killing any threat to its survival. Appears in "The Spanish Moss Murders".

- Impaled with Extreme Prejudice: Kolchak is able to destroy it by stabbing it with a stake made out of swamp plants and wood, which the legend dictated would kill it.
- It Can Think: The longer it stays alive, the smarter it gets. It goes from just murdering anyone that poses a threat to its existence and leaving their bodies in the open to doing it more subtly, hiding Morris's corpse and subtly killing Paul by willing him to die.
- Real After All: Tales of the Night Stalker reveals that the Pére Malfait was real, and the Sagath was created to stop it.
Francois Edmonds
A Haitian number runner, Edmonds was shot and killed by the Mafia for running a rival operation, no matter how small-time it was.

Harold Baker, nicknamed "Swordsman" for his affinity for swords to the point of owning one, was the leader of a teenage biker gang called the Bishops in the 50s. One day, a rival gang called the Jokers rigged a trap to trip Baker off his bike; the trap went wrong and decapitated him, and the leader of the gang kept his skull in a container as a trophy. Baker came back as a headless ghost riding his motorcycle and murdered the Jokers’ leader, and the Jokers realized that the only way to stop Baker was to reunite his head with his body, which they did. Years later, Baker’s corpse was removed from the cemetery when it was purchased as real estate, and his skull was separated from his body once more, freeing him to take revenge against the remaining Jokers.

- "Scooby-Doo" Hoax: He dresses up like Bigfoot to scare people off the Native American Reservation, pretending to be a Wendigo, something the traditionalists on his reservation are terrified of, and those who don’t believe in the legend are still terrified by a wild animal attacking people and brutally killing animals. He tries to use Kolchak to spread the legend, but Kolchak figures out the truth due to Runningwater being far too eager to tell some random white guy he found in the woods about the legend. After he dies, Kolchak runs an exposé on the hoax while leaving out how Gene was killed by the actual Bigfoot, figuring revealing the truth would result in the people on the reservation leaving, and that they had already suffered enough.
