The Saturdays

A family of secret scientists who specialize in cryptids.
  • Adventurer Archaeologist: Who study cryptids.
  • Badass Family: The father is a Genius Bruiser with a power glove, the mother is a martial artist Action Mom with a Flaming Sword, one of the 'kids' is a super strong Gorillacat and the guardian of an ancient doomsday beast, and the son is able to control cryptids, the most powerful animals on earth, and is the reincarnation of the God of the Cryptids. Even the family pets are badass. And the Sixth Ranger of the team is mom's long-lost brother, a trained mercenary with all sorts of badass gear, including a jetpack.
  • Undying Loyalty: They stand together no matter what. Even after Zak was revealed to be Kur, the family stuck by Zak and fought against the scientists friends when they wanted to cryogenically freeze Zak.

    Zak Saturday
Voiced by: Sam Lerner; Ogie Banks (Ben 10: Omniverse Crossover)

Zak Saturday is the 11-year-old (he turns 12 in "Kur Parts 1&2, turns 13 in "Life in the Underground") major character of the show. The son of Doc and Drew Saturday, Zak seeks adventure at every turn, which is easily satisfied by his cryptid-researching family. Zak has an unorthodox upbringing that has taken him around the planet and placed him in the face of danger since the day he was born. Zak was born the same year the Kur Stone was found (specifically, he was conceived shortly before the discovery). Zak has a special psychic ability to connect with cryptids, allowing him to control their actions to an extent. Tamer cryptids seem to trust him instinctively and even fiercer ones can tell that Zak is different from other humans.

  • Adaptation Dye-Job: The crossover with Ben 10: Omniverse gives Zak orangish brown eyes instead of black. And the black part of his hair has red streaks.
  • Affectionate Nickname: "Mini Man" and "Zakman" by Doyle.
  • The Baby of the Bunch: The youngest in his family.
  • Badass Adorable: Tiny and cute with that star shaped mop of hair, but he gets badass right as the first season comes to a close.
  • Bad Powers, Good People: Zak's powers come from being the reincarnation of Kur. And even after learning this shocking truth, Zak is still determined to save the world.
  • Big Brother Instinct: In "The Underground Bride", he gets a wee bit protective of Zon after she develops an attraction toward the Duah. Strangely (and somewhat creepily), Fisk seems to see it more as a case of Crazy Jealous Guy.
  • Break the Cutie: Downplayed, but still present. Zak was raised to believe his powers would allow him to protect the world like the hero he ascribed to be, and this gets even more bolstered by his parents' belief that he's destined to defeat Kur, whom they constantly describe as the ultimate evil. When it's discovered he is Kur, Zak sincerely starts wondering if he's actually the bad guy, despite how hard he tries to do good.
  • Brought to You by the Letter "S": His shirt has a the Tsul 'Kalu in a stylized version of a "S".
  • Child Prodigy: Hinted throughout the show that he's Brilliant, but Lazy, but when the Omniverse Crossover occurred, it shows he's actually fully able to keep up with the more scientific-heavy subjects around him.
  • Curtains Match The Windows: His black eyes and the part of his hair that's black.
  • Demonic Possession: Subverted. He tries to drive out the spirit of Kur, but it becomes clear he's not actually being possessed: he is Kur. The attempted exorcism nearly kills him.
  • Friend to All Living Things: Played with. Zak is an 11 year old boy, so he is a straight portrayal of the innocent bit, but the animals that all snuggle and cozy up to him are cryptids that would give ordinary virgin girls pause. Played darkly when it turns out that this is because Zak is the reincarnation of their civilization-destroying god Kur.
  • Kid Hero: He starts out as 11 and ends the series at 13.
  • Magnetic Hero: He is quick to make friends or at least find common ground between them, like he did with Francis, Ulraj, Wadi, Tsul Kalu, Tica, the cryptids in "Life in the Underground", Fiskerton, Zon, and possibly Komodo.
  • Mixed Ancestry: Zak is half White, half African-American.
  • Momma's Boy: Even though Drew can smothering, Zak has a very tight bond with her.
  • More Than Mind Control: Zak's power influences cryptids, but can't directly control them. For example, he gets a pod of dolphin-like cryptids to perform for him, but it's pointed out that they're natural show-offs to begin with.
  • Multicolored Hair: Part of his hair is white blonde, something he inherited from his mother.
  • My Sister Is Off-Limits!: In "The Underground Bride", he's not happy when the Duah makes the moves on Zon. And justifiably so, as it turns out, seeing as he later discovers that the Duah plans to eat her once he lures her into his lair.
  • Nice Guy: Zak is caring towards cryptids, fast at making friends all around the world, and was willing to sacrifice himself at the series finale.
  • Puppy Love: Downplayed, with Wadi — Both are roughly the same age (starting at 11 and ending at 13), and have crushes on each other.
  • Spiky Hair: Which is constantly made fun of by Dr. Beeman.
  • Tomato in the Mirror: " Kur?!"
  • Took a Level in Badass: Zak gains better control of his powers as the series progresses.
  • Youthful Freckles: Acquires a few in the crossover.

    Doc Saturday

Solomon "Doc" Saturday is the patriarch and the "Indiana Jones"-like character who has spent his whole life studying cryptids.

  • Agent Scully: Always insists there's a scientific explanation for any and all magical occurrences.
  • Alliterative Name: Solomon Saturday.
  • Arbitrary Skepticism: Doesn't believe in magic.
  • Battle Couple: With Drew, as they both are married and regularly go on dangerous missions together.
  • Black and Nerdy: Doc is African-American and is an incredibly intelligent man.
  • Brainy Brunette: A Secret Scientist who specializes in cryptids.
  • Child Prodigy: Implied. Doc started his cryptozoology career on Honey island when he was 12, learning from Dr. Basil Lancaster.
  • Curtains Match The Windows: Like Zak, he was born with black hair and eyes.
  • Gadgeteer Genius: He is a supergenius, having built many of the gadgets the family uses.
  • Genius Bruiser: His incredible strength pales in comparison to his great intellect.
  • Good Parents: He may be harsh, but he only is so when Zak steps out of line, but shows great fatherly love to his son.
  • Good Scars, Evil Scars: A lighting like scar over his left eye.
  • Handicapped Badass: His left eye was blinded from a lab accident. Actually, it was because of his fight with Tsul'Kalu, taking the place of his son after he accidentally destroyed a sacred site Tsul'Kalu.
  • Happily Married: With Drew — effective Battle Couple, are Good Parents to their kids, and show their love for one another in many ways.
  • Heroic BSoD: Whenever his family is threatened or seemingly dies, he breaks down and goes into rage mode.
  • Heroic Build: A huge and tall build.
  • Huge Guy, Tiny Girl: Downplayed with Drew as her height is relatively normal, but Doc's Heroic Build combined with his natural tallness fits this trope.
  • In-Series Nickname: His full name is Solomon Saturday, but he's always referred to as "Doc".
  • Jerk with a Heart of Gold: He can be seen as harsh, strict, over bearing, and brash towards Zak, however this is most likely because he is worried about his son and the dangers in the line of work he is in. He is very much a loving man and shows his affection more with actions than words.
  • Mismatched Eyes: Doc has one dark brown eye, while the other is a sightless blue color due to him being blind in that eye.
  • My Greatest Failure: He blames himself for the problems during the Secret Scientists' assault on Weird World 11 years ago. They got the Kur Stone back, but more than half the scientists died in the process.
  • Papa Wolf: Do not lay a finger on any of his boys, or you'll get a power glove in the face.
  • Red Oni, Blue Oni: The calm Blue Oni to Drew's aggressive Red Oni.
  • Shipper on Deck: Like Drew and Doyle, he (correctly) assumes that Zak has a crush on Wadi in "Curse of the Stolen Tiger", and is seen smiling alongside his wife when Wadi admits she reciprocates.
  • Tall, Dark, and Handsome: Second tallest in his family, African-American, and very handsome.
  • Tall, Dark, and Snarky: With the sarcasm to match.
  • Vague Age: Though his age is not definite, creator Jay Stephens has stated that he "imagined Doc as 40 or so."

    Drew Saturday

Drew Saturday is the matriarch and the one who "believes in the magic," being more prone to accepting things on faith rather than empirical evidence.

  • Ace Pilot: Which she at one point lampshades — Drew has mentioned that she is an ace fighter pilot, which she takes great pride in.
  • Action Girl: She never shies away from a fight with the enemy.
  • Action Mom: A fighter and mother of four.
  • Agent Mulder: Firm believer in magic.
  • Battle Couple: With Doc, as they both are married and regularly go on dangerous missions together.
  • Cain and Abel: The Abel to Doyle's Cain, as while she works to ensure the survival of cryptids, he is a mercenary hired to stop her actions. Subverted since they eventually become allies after they discover they are brother and sister, and Doyle switches to her side.
  • Dude Magnet: Just ask Doc, Van Rook, and Ben.
  • Foolish Sibling, Responsible Sibling: The Responsible to Doyle's Foolish. After he joins them, Doyle's recklessness and immaturity contrasts with Drew's more controlled and mature nature.
  • Gender-Blender Name: "Drew" is typically a male name.
  • Good Parents: A little overprotective, Drew is still a good, caring, and fair mother.
  • Happily Adopted: She was raised by monks, which may be the cause of her belief that not everything needs a reasonable/scientific explanation.
  • Happily Married: With Doc — effective Battle Couple, are Good Parents to their kids, and show their love for one another in many ways.
  • Heroes Prefer Swords: Drew's preferred weapon is the Tibetan Fire Sword given to her by the monks, which absorbs light and channels it into potent bursts of flame. Her sword needs light to access the fire, if there is no light source around it shoots blue flames.
  • Heroic Albino: Implied given her white hair and pale skin, but she is a hero through and through.
  • Hot-Blooded: When she gets in "the zone".
  • Huge Guy, Tiny Girl: The Tiny Girl to Doc's Huge Guy.
  • Idiot Ball: Despite being a famed cryptid expert, before And Your Enemies Closer, she had never once heard of the Yeti plaguing the Himalayan mountains she was raised in despite it being a commonly known cryptids among modern audiences like that of a Chupacabra. Even when it's revealed the monks who raised her didn't tell her about it out of fear of bringing up past traumas, she had more than ample time to know about such a cryptid in adulthood.
  • Mama Bear: Never mess with Drew's babies.
  • Morality Pet: Zigzagged. Van Rook never changed his ways even when he and Drew were dating. However, he does take the fatal hit aimed at her from Argost and his last words are as followed: "Drew, you were the only thing I liked almost as much as money."
  • Mum Looks Like a Sister: She could be mistaken for being her son's older sister.
  • My Beloved Smother: Justified. Drew's smothering over Zak makes sense given their dangerous lifestyle and how little they know about his powers.
  • Oddly Shaped Sword: Drew has a broadsword that is normal except for a sunbeam-shaped sculpture at the top of the blade.
  • Older Than They Look: You wouldn't think she was in her thirties and a mother. In fact, the Ben 10 Omniverse crossover has Drew appear to have age down, making her look like a teen.
  • Omniglot: Drew knows 37 surface languages.
  • Parent Service: Form fitting Spy Catsuit, Hartman Hips, and voiced by Nicole Sullivan.
  • Red Oni, Blue Oni: The aggressive Red Oni to Doc's calm Blue Oni.
  • Shipper on Deck: Like Doc and Doyle, she (correctly) assumes that Zak has a crush on Wadi in "Curse of the Stolen Tiger", and is seen smiling alongside her husband when Wadi admits she reciprocates. In "Life in the Underground", Drew gives Zak some romantic advice in regards to Wadi.
  • Stacy's Mom: In the Ben 10: Omniverse cross over, Ben is immediately smitten by Drew Saturday, which annoys her son Zak to no end because he will not shut up about it.
    Ben: Um, yeah, meeting you is... the good.
    Drew: Oh, right back at you.
    Zak: Dude, that's my mom!
  • Strong Family Resemblance: Like her brother's strong resemblance to their father, Drew has a strong resemblance to their mother, as seen here.
  • Vague Age: Though her age is not definite, Jay Stephens stated that he "imagined her as 34 or so."
  • You Killed My Father: Her hatred for Argost increases even more after she found out he caused the avalanche that killed her parents and separated her from Doyle.

    Fiskerton "Fisk"
Voiced by: Diedrich Bader, Corey Burton (Ben 10: Omniverse Crossover)

Fiskerton, often called Fisk by Zak, is a seven-foot-tall "gorilla-cat" with glowing red eyes, based on the Fiskerton Phantom. He was adopted by the Saturday family when his home was burned down by the locals in Nottinghamshire, England.

  • The Big Guy: The strongest of his family.
  • Beware the Silly Ones: His kind and goofy nature betray the fact that he is a seven-foot-tall superstrong gorilla-cat. When Argost threatened to have Zak kill via a train car collision, Fisk angrily grabbed both Munya and Argost and smashed them through the rear train car door to use Munya's webs to stop the train cars and save Zak.
  • Cats Are Snarkers: He's part-cat and quite the Silent Snarker.
  • Dark Is Not Evil: Condemned as a monster and hunted by the English locals, he was actually quite peaceful. He didn't even try to attack the angry mob threatening him.
  • Exact Words: Lemurians are Kur Guardians, in that they guard against Kur.
  • Gentle Giant: A big guy with a bigger heart.
  • Last of His Kind: "The Kur Guardian" doesn't say for sure, but it sure looks like the rest of his kind are long gone.
  • Mix-and-Match Critters: A Fiskerton Phantom, or "gorilla cat".
  • Nice Guy: He has a sweet personality.
  • Seldom-Seen Species: The Fiskerton Phantom is a "real" cryptid, but this is probably the first time one has been featured in a cartoon. Also, In-Universe, as not even Doc and Drew were able to identify his exact species.
  • Silent Snarker: Tends to sass Zak with his unintelligible voice.
  • The Unintelligible: Although the family and his fellow Lemurian relics can understand him.

Voiced by: Fred Tatasciore

Komodo is a 250-pound, genetically-altered komodo dragon with a voracious appetite.

  • Attention Whore: Komodo can't stand it when someone else gets attention.
  • Big Eater: Jokingly, he would change his allegiance for a good meal.
  • A Dog Named "Dog": Guess what kind of species Komodo is?
  • Extreme Omnivore: Komodo has the ability to eat and digest pretty much anything. This comes in extremely handy on more then one occasion, even if it's a source of perpetual Squick for Zak.
  • Invisibility: Thanks to being a cryptid, Komodo can turn himself invisible.
  • Jerk with a Heart of Gold: Komodo can be quite unpleasant, but ultimately has a good heart.
  • Hollywood Chameleon: Justified, because he's a mutant.
  • Poisonous Person: Averted. He seems to lack the venom Komodo dragons have, given how his opponents are not affected by his bite. This may be justified in that he is a mutant.
  • Seldom-Seen Species: Komodo dragons don't appear very often in cartoons.

Voiced by: Fred Tatasciore

Zon, named after the Amazon rainforest where she was found, is a surviving member of a thought-to-be-extinct Pterosaur species (Tropeognathus) that lives in a nest near the Saturday Headquarters, but isn't truly owned by them.

  • All Girls Want Bad Boys: Toward the the aggressive and rebellious Duah briefly.
  • Big Eater: She eats a lot of fish and chips for a snack.
  • A Day in the Limelight: She rarely gets much focus, but does manage to get an episode of her own in "The Underground Bride".
  • Defeat Means Friendship: Her first appearance was attacking the Saturdays for accidentally destroying her nest. After they subdue her, she takes a liking to them and ends up a member of the family.
  • I Am Not Weasel: She's often referred to as a Pteranodon.
  • Meaningful Name: The Saturdays found her in the Amazon. Bonus points for her being female.
  • No-Sell: The first time Zak meets her, he tries to use the Claw on her. She responds by swatting it out of his hand with her wing.
  • Ptero Soarer: Played with; For one side, she has fur and wings somewhat shaped like a real pterosaur's and she walks on all fours. On the other hand, the wing structure itself is wrong, she is cold-blooded, she has five fingers (including an additional thumb), she can stand on two legs for quite some time and that is how she takes off. It is possible that the anatomical mistakes are just to make her appropriately "cartoony" for the show, as the authors do seem to actually do research.
  • Seldom-Seen Species: A pterosaur that isn't a Pteranodon for once, although she's often referred to as one. She's actually a Tropeognathus (which is actually related to Pteranodon).
  • Smitten Teenage Girl: Acts like...the rough pterosaurian equivalent toward the Duah in "The Underground Bride". It turns out, however, that the Duah is planning on killing and eating her once he marries her.
  • The Smurfette Principle: In essence, Zak's only "sister".
  • Trademark Favorite Food: Fish. Very fitting as her species were fish-eaters in real life.

    Doyle Blackwell
Voiced by: Will Friedle

Uncle Doyle is Zak's biological uncle, Doc's brother-in-law and Drew's long-lost younger brother. He first appears as Van Rook's apprentice in "The Kur Stone". He helps Zak put a tribe of Amaroks back into hibernation in "The Ice Caverns of Ellef Ringnes", starting a stable relationship with him. At first, he and the Saturdays are unaware of any biological relationship. In "Van Rook's Apprentice", he changes sides and joins the Saturdays after learning he is Drew's brother and about V.V. Argost's true motives.

  • Anti-Role Model: He can be somewhat of a bad influence on Zak due to his methods and morals.
  • Big Little Brother: He's younger than Drew, but is one head taller than her.
  • Cain and Abel: The Cain to Drew's Abel, as while she works to ensure the survival of cryptids, he is a mercenary hired to stop her actions. Subverted since they eventually become allies after they discover they are brother and sister, and Doyle switches to her side.
  • Chuck Cunningham Syndrome: Doyle doesn't make an appearance in the Ben 10: Omniverse crossover with the Saturdays or even have a cameo.
  • Cool Uncle: Deconstructed. His devil-may-care attitude may seem cool to Zak given the his age, but Doyle's stunted growth is a real problem, something Doc doesn't want his on to be influenced by.
  • Dark and Troubled Past: Was separated by his family at a very young age. Grew up from orphanage to orphanage. And somehow ended up as a mercenary.
  • Delinquent Hair: Of the mow-hawk variety.
  • Foolish Sibling, Responsible Sibling: The Foolish to Drew's Responsible. After he joins them, his recklessness and immaturity contrasts with Drew's more controlled and mature nature.
  • Jerk with a Heart of Gold: Smart-mouthed, cocky, childish. And because of his Dark and Troubled Past, he usually keeps people at an emotional distant, but when the situation calls for it, he proves to truly care for his family.
  • Leeroy Jenkins: Doyle prefers the term "improvising".
  • Manchild: A trait that's pointed out by Doc when he calls out Doyle for how his immature behavior is a very dangerous flaw.
  • Morality Pet: Zig zagged. But his presence softens Van Rook's jerkish tendencies.
  • Mr. Fanservice: He has quite the handsome build. And he knows it.
  • The Nicknamer: Gives a lot nicer nicknames than Dr. Beeman's.
  • Obnoxious In-Laws: Doc seems to think this given Doyle's immature, reckless stunts put them and their family in danger. He's not wrong. Subverted when Doyle survives Weird World twice, earning Doc's respect and asking him to teach Zak.
  • Papa Wolf: He is quite protective over his nephew, Zak.
  • Secret Keeper: He overhears that Fiskerton might have some connection to Kur. He agrees to keep it a secret until Fisk's ready to tell the family.
  • Shipper on Deck: Like his sister and brother-in-law, he ships Zak and Wadi.
  • Strong Family Resemblance: Like his sister's strong resemblance to their mother, Doyle has a strong resemblance to their father, as seen here. This was even the first step in Drew discovering that Doyle was her long-lost brother.


    V.V. Argost
Voiced by: Corey Burton

V.V. Argost is the series' main antagonist and the archenemy of the Saturdays.

  • Ambiguously Human: The pale white skin and hair, pointed fingers and face make if hard to think he's human. He's not.
  • Arch-Enemy: To the entire Saturday family, for different reasons. Doc was obsessive in defeating him over losing friends and years of being unable to take him down. Drew and Doyle when they learned he murdered their parents. Zak averted this due to being a fan of his show, Weird World. This changes over their repeated encounters, primarily because Zak interfered with his plans and was revealed to be Kur.
  • Back from the Dead: In Ben 10: Omniverse, thanks to Dr. Animo.
  • The Beastmaster: V. V. Argost uses his knowledge of cryptids to bring a variety of them into any fight he might find himself in.
  • Big Bad: Of the entire series.
  • Bigfoot, Sasquatch and Yeti: Argost turns out to be a yeti.
  • But for Me, It Was Tuesday: When Drew and Doyle confront him over murdering their parents, he sadistically says he can't be bothered to remember every victim he ever had but doesn't rule out that he certainly killed their parents.
  • Catchphrase: "Greetings and bienvenue!"
  • Dark Is Evil: Wears a sinister black cloak.
  • Depraved Kids' Show Host: He hosts a television show titled "Weird World", which made him a Villain with Good Publicity. Uniquely he acts the same on camera as he does off camera.
  • Evil Is Petty: Admits he is a petty person after he tried to kill Zon by melting her insides with acid pellets for stopping his plans.
  • Evil Mentor: Plays this completely straight to Zak after finding out he is Kur. He even lampshades this trope when he explains helping Zak makes him no less evil and manipulative and once he is finished with Zak he will certainly try to kill him after.
  • Expressive Mask: He wears a mask, which moves with his lips so well you wouldn't think it was a mask at first glance.
  • Faux Affably Evil: He acts overtly dramatic and has a sense charisma in the way he presents himself, but he'll quickly switch to being murderous and relentless if something gets in his way.
  • From Nobody to Nightmare: Argost used to be a nameless vicious Yeti in the Himalayan Mountains killing and stealing belongings from travelers before becoming an infamous villain and scientist.
  • Gratuitous French: His speech is often peppered with French. Case and point, his catch phrase above, which is said a lot.
  • Knight of Cerebus: Once Argost makes the scene, things become much more dire.
  • Large Ham: Argost is nothing if not theatrical. Many of his plans are even fueled by his self-admitted weakness for engaging in the classic monster cliches.
  • Learnt English from Watching Television: He learned how to speak through a television set with black and white horror films. It's also likely where he got his accent and way of speaking.
  • Made of Indestructium: His coat is made from Megatooth shark skin, which has let him survive blasts of fire and even explosions with nary a scratch.
  • Serial Killer: Even before becoming Argost, he murdered a lot of people For the Evulz, including Drew and Doyle's parents.
  • The Sociopath: Argost has absolutely no empathy or sympathy for anyone and only cares about garnering power for himself despite his affable tendencies. This trait is flat out mentioned by Zak who describes how Argost knows nothing of personal sacrifice for loved ones before tricking Argost into destroying himself by temporarily sacrificing his life.
  • Villain with Good Publicity: Thanks to his popular TV show, Argost has gain a number of followers.
  • Villainous Breakdown: Has a notably savage one when he first thinks he's taken control of Kur and gets a brutal beating from Zak for his trouble. He goes from a collected gentleman to a raving madman lunging at Zak and ranting about his delusions of greatness before eventually asking his minion Munya to make the Saturdays suffer even at the cost of his life.
  • White Hair, Black Heart: Has white hair and is the Big Bad.
  • Would Hurt a Child: Argost has no qualms over killing Zak. Especially when it's revealed that Zak is Kur.
  • You Killed My Father: He killed Drew and Doyle's parents, not that he remembers.
  • Yin-Yang Bomb: Makes the mistake of absorbing Zak's matter Kur powers while already having Zak Monday's antimatter Kur powers. Unfortunately for him, the 'bomb' part is extremely literal, and going off inside him.


Munya is V.V. Argost's silent and mysterious manservant.


    Leonidas Van Rook
Voiced by: Corey Burton

Leonidas Van Rook is a ruthless cryptozoologist who is the ally of V.V. Argost and a rival of Doc Saturday.

  • Dying Declaration of Love: "Drew, you were the only thing I liked almost as much as money."
  • Even Evil Has Standards: Admits that even he's disgusted to learn Argost murdered people as the yeti for pleasure and kept souvenirs of each kill, including Drew and Doyle's parents.
  • Greed: He only does thing for the money.
  • Helmets Are Hardly Heroic: As of part of his Heel–Face Turn, Van Rook starts to not wear his helmet more often.
  • Jerkass: To be expected of a mercenary.
  • Jerk with a Heart of Gold: A hired mercenary who sacrifices himself to protect Drew.
  • Killed Off for Real: And it's surprisingly heartbreaking.
  • Mean Boss: He trains his apprentices and pays well, but he also sticks them with grunt work, belittles them, and charges them for damaged equipment. Doyle admits he actively fantasized about clobbering him well-before switching sides.
  • Psycho Ex-Boyfriend: He and Drew used to date in College. He still hits on her.

    Zak Monday 
Voiced by: Sam Lerner

Zak Saturday's Evil Counterpart. Out of the Monday's Zak Monday was the most reoccurring alongside Komodo Monday before they are sent back to their universe.

  • Ax-Crazy: WAY less composed than his good counterpart. He's extremely cruel and criminally insane, and is quite boastful about being both.
  • Do with Him as You Will: When he and Komodo Monday are sent back to the mirror world in their second appearance, their family (whom they had just left behind) gives them exactly what they deserve...
  • Enemy to All Living Things: Has his own version of the Claw, the Fang. Instead of commanding cryptids, however, it drives them into a berserk frenzy.
  • Evil Twin: No points guessing who of.
  • Killed Off for Real: In the finale, Argost drains him of his power, killing him in the process.
  • Palette Swap: His hair is black on top and white on the bottom, an inversion of Zak Saturday's.
  • Slasher Smile: His default expression.
  • Smug Snake: He always has a smile even when he's losing.

    The Mondays 
Voiced by: Phil Morris, Nicole Sullivan, Diedrich Bader and Fred Tatasciore

The Mondays are the Saturdays' evil antimatter duplicates from a parallel universe, summoned by the Smoke Mirror of Tezcatlipoca. They are not well liked in their reality, most likely being criminals. Each Monday has a distinguishing characteristic that sets them apart from the Saturdays and cause reality to warp when in the presence of their duplicates.

  • Big Bad: Komodo appears to be their leader.
  • Dumb Muscle: Doc Monday, in stark contrast to his counterpart.
  • Even Evil Has Loved Ones: Subverted. They're quite content to backstab each other whenever it's most fitting.
  • Evil Twin: To the Saturdays.
  • Eyes Do Not Belong There: Zon Monday has eyes on her wings for some reason. Although they might not be real eyes.
  • Faux Affably Evil: Drew Monday acts all nice when we first see her. The keyword here is "acts".
  • Five-Man Band:
  • Meaningful Name: Zak opts to call them "Mondays", because Mondays are the boring opposites of Saturdays.
  • Overly Long Tongue: Drew Monday, apparently. It's what gives her away.
  • The Psycho Rangers: Deconstructed. They're the evil twins of the Saturdays, and they have little regard for each other. They can work together short-term, but things fall apart because of mutual distrust and dislike. Zak and Komodo even gladly abandon the others for their own benefit.
  • Sealed Evil in a Can: Sort of. The antimatter universe is a wide open world, but they're hated and hunted there. They want to start fresh by taking the Saturdays' places.
  • Smug Snake: Drew and Komodo Monday.
  • Spot the Imposter: Doc Monday has an Eyepatch of Power, Fisk Monday has horns in place of his ears, Komodo Monday has spots on his back that can spread all over his body and form an impenetrable shield (and he can talk), Zon Monday has massive eyes on her wings and Drew Monday has a long, prehensile tongue.
  • Suddenly Voiced: Komodo Monday can talk. His first line pretty much summarizes how everyone (viewers included) feel about this...
    Komodo Monday: Are you disturbed yet? (the looks on the family's collective faces pretty much say yes)


    Dr. Arthur Beeman
Voiced by: Jeff Bennett

Dr. Arthur Beeman is a Secret Scientist who studies aliens and UFOs.

  • Brainy Brunette: He is a Secret Scientist.
  • Jerkass: From his condescending nicknames towards Zak to being the most gleeful of the Secret Scientists of forcefully taking Zak away from his family when it's revealed he's Kur.
  • Motor Mouth: Only when it comes to his work.
  • The Nicknamer: Especially towards Zak i.e. "Pandahead", "Porcuperm", "Spikeylocks", etc.
  • Smart People Wear Glasses: Beeman broke a Crop Circle code in 2003 which saved the Earth from invasion.
  • Token Evil Teammate: Of the Secret Scientists. It's best summed up when Beeman was about to give a lethal dose of the Flute of Gilgamesh to both Argost and Zak. With a smile on his face.

    Dr. Paul Cheechoo 
Voiced by: Danny Cooksey

Dr. Paul Cheechoo is a Secret Scientist that specializes in cold-climate research, he and a team of experts travel the Earth studying strange geological anomalies.

  • Brainy Brunette: A Secret Scientist who specializes in cold weather research.
  • Canada, Eh?: It was mentioned that he's from Canada.

    Dr. Miranda Grey 
Voiced by: Susan Blakesle

Voiced by: Adam Wylie

The young prince of Kumari Kandam (supposedly about a year older than Zak, making him 12-14 in the series) whose father was killed in an assault orchestrated by V.V. Argost. He allied with Zak to reclaim his kingdom from V.V. Argost.

  • A Child Shall Lead Them: Becomes the King of Kumari Kandam after his father's death.
  • Friendly Rivalry: To Zak, as Ulraj will challenge the former in anything, but still considers him a friend.
  • Jerk with a Heart of Gold: He can come off as pompish and arrogant, but ultimately has a good heart. Pretty much summed up in this quote:
    "Please Doctor Saturday, anyone who helps saving the empire kingdom of Kumari Kandam has earned the right to call me Ulraj. (to Drew) You were unconsious most of the time. Your highness will be fine."
  • Omniglot: Ulraj knows 14 surface languages, including French and English.
  • Royal Brat: Downplayed. He's a prince (later king) and has a haughty attitude, but does has his nicer moments.
  • You Killed My Father: Averted. Despite wanting Argost taken down, he decided revenge for his father was pointless.

Wadi is the daughter of Maboul and Zak's love interest. Wadi is a kleptomaniac, which her father disapproves of (even though after the events of "Eterno", she has vowed to recover stolen property).


The Kur Stone, which contains his essence.
An ancient Sumerian being of incredible destructive power whose essence was contained inside the Kur Stone. It's left ambiguous whether he was a god of cryptids or simply a powerful cryptid himself; he's spoken of varyingly as both. Doc and Drew refer to him throughout the first season as "the ultimate evil," and Argost seeks to use his powers to enslave the world.
  • Informed Attribute: Kur is said to be "the ultimate evil," but we never really hear about anything he did to earn that title.
  • Living MacGuffin: The entire first season is just one long journey to find him before Argost.
  • Posthumous Character: In a way. Argost and the Saturdays go out of their way to find his location, only to discover his tomb. He's actually been reincarnated as Zak, but for all intents and purposes, whatever personality Kur had is dead.
  • Psychic Powers: Seems to have been able to control armies of cryptids mentally.
  • Sealed Evil in a Can: His soul inhabited the Kur Stone until Doc and Drew's archeological team broke it. It then jumped to Drew's unborn son.
  • Shrouded in Myth: Despite his importance to the plot, we actually learn very little about him throughout the show, only that he was some sort of Cryptid warlord-god figure from Sumer and that his spirit was contained inside the Kur Stone. His deeds seem to be legendary, but we never hear about them.
  • Soul Jar: What he existed in, until Doc and Drew's dig team broke it.
  • Villainous Legacy: The legends about his powers from Ancient Sumeria (and the discovery of his Soul Jar at the dig) are what gets Argost interested in him and causes the plot.
  • Walking Spoiler: The fact that he's actually Zak makes him one.
