The Saturdays

    General 
https://static.tvtropes.org/pmwiki/pub/images/1_06.jpg
"We're the only things standing between you and all the things that go bump in the night. That's gotta make you feel safe, huh?"

The Saturday family belongs to the Secret Scientists, an international coalition dedicated to uncovering the secrets of the universe before the bad guys get the chance. Each scientist is specialized in a specific field, and the Saturdays happen to be cryptozoologists, studying the animals "regular science doesn't believe in."

The family is made up of parents Doc and Drew, their son Zak, his adopted brother Fiskerton, pets Komodo and Zon, and a secret, long-lost uncle named Doyle.


  • 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 "gorilla-cat," and their son is able to influence cryptids, and is the reincarnation of Kur, who is capable of raising and controlling a cryptid army. Mom's long-lost brother is a trained mercenary with all sorts of badass gear, including a jetpack and stun grenades. Even the family pets are badass, featuring an Ornithocheirus and a Komodo dragon that can turn invisible.
    • As revealed in the comics, the entire Saturday family line is made up of geniuses and daredevils.
  • Charles Atlas Superpower: His family is regularly seen doing training drills, and are all capable of superhuman feats of strength and martial prowess. Comes in handy when they wrestle with the world's most dangerous animals.
  • Family Portrait of Characterization: The family has a normal family photo, but to either side are also photos of them fishing dunkleosteus and being attacked by exploding snakes.
  • Family Theme Naming: Between Zak, Solomon, and an Elijah and Samuel revealed in the supplementary material, it's clear that the men in the Saturday family tree have biblical names. Doyle and Drew, meanwhile, share names with Gaelic origins.
  • Undying Loyalty: They stand together no matter what. That's what family means.

    Zak Saturday 
https://static.tvtropes.org/pmwiki/pub/images/555640_zak_1_large_3.jpg
Click here to see him in the Ben 10/The Secret Saturdays crossover 
Voiced by: Sam Lerner; Ogie Banks (Ben 10: Omniverse Crossover)
"Everybody has secrets. My family just has bigger ones. They're called 'cryptids'..."

Zak is the plucky kid protagonist, a boy with a penchant for getting himself in trouble and a wide-eyed excitement for all the cool, dangerous things in the world. He has the ability to influence cryptids — unique creatures with strange abilities. His parents believe he was gifted these powers so as to cosmically balance the evil they unleashed when the unearthed the Kur Stone shortly before Zak was born.

He starts the series at eleven years old, and is thirteen by the series end. At the end of Season One, it's revealed that he's the reincarnation of Kur, and finding a "solution" to this problem drives the plot for much of the second season.


  • Adaptation Dye-Job: The crossover with Ben 10: Omniverse gives Zak orange eyes instead of black.
  • Affectionate Nickname:
    • "Mini Man" and "Zakman" by Doyle.
    • He also catches a lot of nicknames from Beeman, although how affectionate they are is slightly more up for debate.
  • Anti Anti Christ: Zak is the reincarnation of Kur, a cryptid worshiped as an evil deity. Kur is said to have destroyed civilizations and is destined to do it again, starting with humanity. Zak's not too happy about this.
  • Back from the Dead: He dies for about three minutes before his family manages to resuscitate him in the series finale.
  • Badass Adorable: He's a plucky, adorable preteen who regularly undergoes training drills with his family, for use in wrangling the most dangerous animals on the planet.
  • Bad Powers, Good People: Zak's powers come from being the reincarnation of Kur. Even after learning this, Zak is still determined to save the world.
  • Big Brother Instinct: In "The Underground Bride", he gets protective of Zon after she develops an attraction toward the Duah, outright calling her his sister. He also immediately takes to Fiskerton when Fisk is first adopted, covering for him when he accidentally breaks a bed by jumping on it too hard and assuring him that he's part of the family.
  • Break the Cutie: Zak was raised to believe his powers would allow him to protect the world, and his parents believe he's a force for good who was born to balance out Kur's evil. When it turns out that Zak is Kur, the universe then proceeds to hammer home that everyone expects him to turn out to be an evil, humanity-destroying monster.
  • Brought to You by the Letter "S": His shirt has a big "S" emblazoned on it that's stylized to look like a snake. This may be Foreshadowing to how Zak is actually Kur, which is associated with snakes.
  • Child Prodigy: It's hinted throughout the show that he's Brilliant, but Lazy, as he's capable of handling Saturday tech, flying jets, and strategizing with his parents. In the Ben 10: Omniverse crossover, his familiarity with science is more fully on display.
  • The Chosen One: His mother believes that he was born to bring balance to the evil they unleashed with the unearthing of the Kur stone; his father states that "for every action, there is an equal and opposite reaction" This is the explanation for his powers for much of the show. However, right at the end of the Season One finale, it's cruelly subverted; Zak has powers not because he's meant to fight against Kur, but because he is Kur. Since Kur is destined to Kill All Humans, Zak is still a Chosen One...just an evil one.
  • Demonic Possession: Subverted. His family tries to drive out the spirit of Kur using the Flute of Gilgamesh, but it becomes clear he's not actually being possessed: he is Kur. The attempted exorcism nearly kills him.
  • Despair Event Horizon: He very nearly crosses this in Season 2. He realizes that the visions Tsul'Kalu has been showing him of a future where he turns evil aren't his own worst fears...they're Tsul'Kalu's, and that Tsul'Kalu returned for the Claw to keep it away from Kur. After a whole season of Break the Cutie, realizing that even the good cryptids think he's destined to turn evil causes him to wonder aloud why he even bothers trying to fight against his fate. However, since Tsul'Kalu decides to entrust him with the Claw after seeing Zak's sincere desire to do good, Zak manages to narrowly avoid succumbing.
  • Evil Me Scares Me: Zak is given multiple visions in Season 2 of himself fulfilling Kur's destiny to turn evil and massacre the humans. He claims that this is his worst fear.
  • Friend to All Living Things: Zak loves animals, and cryptids have a tendency to become extremely friendly toward him, especially after he's used his cryptid-influencing power on them. Subverted when it's revealed that this natural affinity cryptids hold for him may be a result of him being the reincarnation of an evil, civilization-destroying cryptid himself.
  • Heroic Sacrifice: Has one at the end of the series - he doesn't know exactly what Argost has in store for him, but he's willing to fight Argost one-on-one in order to prevent any more death.
  • Homeschooled Kids: Justified. Zak's homeschooling consists of more wrestling with dangerous animals than usual, though.
  • Hot-Blooded: Just like mom. Seems like It Runs in the Family.
  • Kid Hero: He starts out at age 11 and ends the series at 13.
  • Magnetic Hero: Zak is very friendly, and quickly ingratiates himself with other kids his age.
  • Meaningful Name: Zak is likely short for some variation of Zakarya, to tie into the Saturdays' biblical names. It means "God has remembered," possibly referencing the fact that he's the reincarnation of Kur.
  • Messianic Archetype: In order to save humanity, Zak gives up both his powers and his life and dies for three minutes before being resuscitated. His parents also initially believed him to have been born in order to counteract the evil they unleashed with the unearthing of the Kur Stone.
  • Mixed Ancestry: Zak is half white, half African-American.
  • Momma's Boy: Zak loves his mom, and takes after her in many respects, most notably in his willingness to throw himself into dangerous situations.
  • More Than Mind Control: Zak's power influences cryptids, but can't directly control them. For example, when he gets a pod of dolphin-like cryptids to perform for him, it's pointed out that they're natural show-offs to begin with, and he can't get the same effect by ordering a cryptid to do something it doesn't want to do.
  • Multicolored Hair: Part of his hair is white, and the rest of it is black. Vitiligo, maybe?
  • My Sister Is Off-Limits!: In "The Underground Bride", he's not happy when the Duah makes 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 and quick to make friends. He tries to do the right thing whenever he can.
  • Personal Horror: Tsul'Kalu shows him visions of an evil future self destroying humanity and personally killing humans; he initially thinks he's being shown his own worst fear. Turns out it's actually Tsul'Kalu's worst fear, but either way, it almost pushes Zak over the Despair Event Horizon.
  • Power Incontinence: In Season 2, after it's revealed that he's Kur.
    Zak: It's like [my powers] know I know.
  • Pre-Asskicking One-Liner: Zak's a huge fan of these. Doyle has been mentoring him; they're seen encouraging each other and trading off different lines.
  • Psychoactive Powers: They grow stronger when they need to. In Season 2, when he's confident in himself, his powers work for him, and when he's full of self-doubt, they start acting like how he imagines Kur's powers would act - deliberately misleading him and causing harm to others.
  • Puppy Love: Downplayed, with Wadi — Both are roughly the same age and appear to have crushes on each other.
  • Spiky Hair: Commented on and ridiculed by Dr. Beeman.
  • Then Let Me Be Evil: Zak uses this as a ploy to get Rani Nagi on his side, so he can get access to the Flute of Gilgamesh that the naga are guarding.
  • Tomato in the Mirror: "Zak...is Kur?"
  • Took a Level in Badass: Zak gains better control of his powers as the series progresses.
  • Wide-Eyed Idealist: From his staunch belief that being family means forgiving Doyle even after it seems he's lured the Saturdays into a trap, to going back to save a cryptid even while he's actively being hunted down, Zak believes that there is good in the world, and that they should do it while they can. This attitude has sparked at least one Heel–Face Turn.
  • Youthful Freckles: Acquires a few in the crossover.

"Or, in terms I'm more comfortable with, for every action, there's an equal and opposite reaction."

Solomon "Doc" Saturday is a genius inventor, engineer, and the world's leading cryptozoologist. He's the gadgeteer behind the invention of their airship, his own battle glove, and many of their other weapons.

Calm and cool-headed, he often acts as the leader of the Secret Scientists.

  • Alliterative Name: Solomon Saturday.
  • Arbitrary Skepticism: Doesn't believe in magic, despite his wife's fire sword and his son's clearly mystical powers. To be fair, in this universe, it appears as though everything may indeed have a scientific explanation.

  • In-Series Nickname: His full name is Solomon Saturday, but he's always referred to as "Doc."

  • My Greatest Failure: He blames himself for the thirty-three deaths that resulted from the Scientist's raid on Weird World 11 years prior to the story.

    Doc: No. I don't care. I'm not turning around to look at it. It's over. We won.
  • Roaring Rampage of Revenge: Goes on one when he believes Weird World has killed off his family, and very nearly single-handedly defeats Argost and Munya.
  • Shipper on Deck: Like Drew and Doyle, he 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.
  • The Stoic: His usual role, to counterbalance all the hot blood in the rest of the family.
  • Tall, Dark, and Handsome: Second tallest in his family, African-American, and very handsome.
  • Tall, Dark, and Snarky: With the sarcasm to match. Specifically, he likes to point out bad science.
  • Unstoppable Rage: It takes a lot to make Doc angry, but god help you if you make Doc angry.

Voiced by: Nicole Sullivan, Vanessa Marshall (Ben 10: Omniverse Crossover)
"When have I ever done anything rash or irresponsible?"

Drew Saturday was separated from her parents in a freak snowstorm in the Himalayas when she was a young child and wound up in a Tibetan monastery. The monks there raised her and granted her her Flaming Sword. She's an archeoloist, biologist, and cryptozoologist with a penchant for the mystic and the magic in the world.

While Doc handles the weaponry and the inventions, Drew handles the human side of things - she's well-versed in several ancient languages and cultures, and on the whole performs much better in social situations than the other members of the family.


  • Ace Pilot: She's not happy that she has to fake being shot down, since this is a huge blow to her cred.
  • Action Girl: She never shies away from a fight.
  • Action Mom: A fighter and mother of four.
  • Age-Gap Romance: Implied, as the creators are vague over her and Doc's ages. However, it's stated that Drew is "34 or so" while Doc is "40 or so", implying that the couple has at least a six year age difference.
  • Agent Mulder: Firm believer in magic.
  • Battle Couple: With Doc. They're Happily Married and fight off bad guys.
  • Cain and Abel: Drew is a Secret Scientist working to save cryptids, and Doyle is a mercenary being paid to do Argost's dirty work. Subverted since they eventually become allies after they discover they are brother and sister, and Doyle switches to her side.
  • Dark and Troubled Past: She was separated from her parents and younger brother during a snow avalanche when she was a child. Thankfully, she was Happily Adopted by Tibetan monks.
  • Dude Magnet: Just ask Doc, Van Rook, and Ben in the crossover.
  • Flaming Sword: Her sword is powered by sunlight and shoots fireballs. At night, it's powered by moonlight, and its flames turn blue to match.
  • Foolish Sibling, Responsible Sibling: The Responsible to Doyle's Foolish. While she's a responsible cryptozoologist, mother, and wife, her brother is an immature, reckless Manchild. All the same, she's more than happy to throw down with him in a good ol' fashioned bout of Sibling Rivalry.
  • Good Parents: Drew cares deeply for her kids' well-being.
  • Happily Adopted: She was raised by Tibetan monks.
  • Happily Married: With Doc — they're an effective Battle Couple, are Good Parents, and regularly go on date nights and flirt with each other.
  • Heroes Prefer Swords: Drew's preferred weapon is the Tibetan Fire Sword given to her by the monks that took her in. It only works in the presence of sunlight (or moonlight), with its flames turning orange or blue to match.
  • Hot-Blooded: She's easily provoked into combat, even announcing the family's arrival at Weird World by blasting the gates open.
    Drew: It's not like he doesn't know we're coming.
  • Huge Guy, Tiny Girl: The Tiny Girl to Doc's Huge Guy.
  • Hypocritical Humor: She warns Doc away from engaging in a "pointless macho contest" with Doyle, before actively participating in one with him herself.
    Doc: If it means anything, I think you won the pointless macho contest.
  • It's Personal: Originally had a professional hatred for Argost, but this upgrades into It's Personal territory when it's revealed that he killed her parents.
  • Mama Bear: Never mess with Drew's babies.
  • Meaningful Name: Drew is a Gaelic name meaning "descended from druids," referencing her mystical tendencies.
  • Oddly Shaped Sword: Drew has a broadsword with a dragon carved into the hilt and a splay of fire at the tip. It's based on the bodhisattva Manjushri's flaming sword, which symbolizes wisdom.
  • Older Than They Look: You wouldn't think she was a mother in her thirties. In fact, the Ben 10 Omniverse crossover has Drew appears to have aged down.
  • 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.
  • Roaring Rampage of Revenge: Tries to go on one against Argost, but is stopped by Zak, who doesn't want her to give in to her darker inclinations.
  • Shipper on Deck: Like Doc and Doyle, she 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.
  • Shown Their Work: Her Flaming Sword is a reference to the one wielded by the bodhisattva Manjushri. It symbolizes wisdom that cuts through ignorance and duality. As it was gifted to her by Buddhist monks, it makes sense for it to be a Buddhist symbol.
  • Stacy's Mom: In the Ben 10: Omniverse cross over, Ben is immediately smitten by Drew Saturday, which grosses Zak out.
    Zak: Dude, that's my mom!
  • Strong Family Resemblance: Like her brother's resemblance to their father, Drew has a resemblance to their mother.
  • Vague Age: Though her age is not definite, Jay Stephens stated that he imagined her as "34 or so."
  • White Hair, Black Heart: An inversion. Drew has white hair but is heroic character.
  • You Killed My Father: Argost killed her parents and caused the snowstorm that separated her from Doyle.

    Fiskerton "Fisk"

Voiced by: Diedrich Bader, Corey Burton (Ben 10: Omniverse Crossover)
"Action time!"

Fiskerton, often shortened to "Fisk," is Zak's adopted brother and a seven-foot-tall "gorilla-cat" called the Fiskerton Phantom. In late Season One, he's revealed to be a Lemurian, an ancient race of "Kur Guardians" who have dedicated themselves to guarding the world from Kur's evil.

Goofy, fun-loving, and just as prone to getting in trouble as Zak is, Fiskerton is rarely ever seen without his brother. He communicates in unintelligible grunts, but Zak seems to be able to understand him just fine.


  • Beware the Silly Ones: He may be kind and goofy, but he is a seven-foot-tall superstrong gorilla-cat. He can strong-arm even Argost and Munya with sheer physical strength alone.
  • The Big Guy: The strongest of his family, being a huge gorilla-cat and all.
  • Cats Are Snarkers: He's part cat and sometimes plays the role of a Silent Snarker.
  • Dark Is Not Evil: Seven feet tall, nocturnal, with glowing red eyes, Fiskerton was chased by an angry mob when the Saturdays found him and took him in. He's actually one of the most kindhearted and goofy members of the main cast.
  • A Dog Named "Dog": A Fiskerton phantom named Fiskerton.
  • Exact Words: Lemurians are Kur Guardians, in that they've been charged with guarding the world against Kur.
  • Gentle Giant: A big guy with a bigger heart.
  • Happily Adopted: By the Saturdays.
  • Last of His Kind: He may very well be the last of the Lemurians.
  • 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 Zak seems to be able to understand him no matter what, and his growls are sometimes human-like enough that the other characters can make them out.
    Drew: You can growl "c'est l'amour," but you can't understand sarcasm?
    • Word of God has stated that Diedrich Bader was given a script in English of what Fiskerton is saying, which the VA then translated into "Fisk-speak."

    Komodo 
https://static.tvtropes.org/pmwiki/pub/images/komodo_large.jpg
Voiced by: Fred Tatasciore

Komodo is a 250-pound, genetically-altered Komodo dragon with a voracious appetite. He has the power to turn invisible, which can be harnessed to turn the Saturday's airship invisible as well.


  • Attention Whore: Komodo can't stand it when someone else gets attention...or, rather, when someone else gets fed.
  • Big Eater: If there's meat, eggs, or fish on-screen, Komodo is seen salivating over it.
  • A Dog Named "Dog": Guess what animal "Komodo" is?
  • Extreme Omnivore: Komodo has the ability to eat and digest pretty much anything. This comes in ]handy on more then one occasion, even if it's a source of perpetual Squick for Zak.
  • Invisibility: What sets Komodo apart from the rest of his species and puts him into cryptid territory is the ability to turn invisible.
  • Hollywood Chameleon: Justified, because he's a cryptid.
  • Jerk with a Heart of Gold: Komodo can be quite unpleasant, but he genuinely cares about Zak's well-being and will fight to defend his family.
  • Lovable Lizard: Rarely enough, a giant Komodo dragon rather than a cute little lizard. He's not quite as friendly as most other examples, but his family loves him just the same.
  • 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 cryptid, and thus his abilities deviate significantly from the norm.
  • Uplifted Animal: Komodo has been confirmed to be more intelligent than an actual Komodo dragon. He's even seen piloting a ship!
  • Seldom-Seen Species: Komodo dragons don't appear very often.

    Zon 
https://static.tvtropes.org/pmwiki/pub/images/zon_large.jpg
Voiced by: Fred Tatasciore

Zon, named after the Amazon rainforest where she was found, is a pterosaur holdout from the prehistoric era. The Field Guide states that she's from the Tropeognathus genus. After the Saturdays accidentally crash-land into her nest in their first episode, they decide to take her in.

She lives outside the Saturday HQ, and later joins Doyle as his partner in crime.


  • Action Girl: Her first appearance is fighting, and she remains a fighting force for the rest of the series.
  • All Girls Want Bad Boys: Toward the the aggressive Duah.
  • Big Eater: She can wolf down buckets and buckets of fish at a time.
  • 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. Between her, Fisk, and Komodo, it's pretty clear that Zak does not exactly have the most creative naming sense.
  • 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.
  • Ptero Soarer: While she does showcase many of the usual inaccuracies (cold-bloodedness, prehensile feet, incorrect wing anatomy), it's possible these mistakes were deliberately made in order to make her more "cartoony" for the show, as the authors do seem to do their research most of the time.
  • 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.
  • Shown Their Work: For all the Artistic License – Biology the show has taken, Zon is actually the correct size for her genus, and since pterosaurs had pycnofibres, her crest may be made of pycnofibres.
  • Smitten Teenage Girl: Acts like the pterosaur equivalent toward the Duah in "The Underground Bride".
  • The Smurfette Principle: Zak's only "sister".
  • Trademark Favorite Food: Fish. Very fitting as her species were fish-eaters in real life.

    Doyle Blackwell 
https://static.tvtropes.org/pmwiki/pub/images/doyle_ss.png
Voiced by: Will Friedle
"Hey, anytime you want to see my terminal velocity, just ask."

Doyle is Drew's long-lost younger brother and Zak's uncle. He makes his first appearance as Van Rook's apprentice mercenary, but after being prompted by Zak to question Argost's motives, he has a Heel–Face Turn and joins the family.

He was separated from Drew during an ill-fated hiking trip their family took to the Himalayas, and after that, was raised as an orphan in Tibet before eventually falling in with crime and the mercenary business. However, with the acceptance of his family, he's put that life behind him and helps out with the Saturdays...for a reasonable fee.


  • Anti-Hero: Even after his Heel–Face Turn, Doyle still has the most questionable morals of his family.
  • Anti-Role Model: He can be a bad influence on Zak due to his methods and morals. An argument over his rash, lone-wolf behavior eventually causes the family to ask him to leave.
  • The Apprentice: Doyle was Van Rook's apprentice before switching sides.
  • Big Little Brother: He's younger than Drew, but one head taller.
  • Cain and Abel: The Cain to Drew's Abel; Drew is a Secret Scientist working to save cryptids, Doyle is a mercenary being paid to do Argost's dirty work. Subverted since they become allies after Doyles Heel–Face Turn.
  • Chuck Cunningham Syndrome: Doyle doesn't make an appearance in the Ben 10: Omniverse crossover.
  • Cool Uncle: His devil-may-care attitude are incredibly cool to Zak, but Doyle's rash behavior and lone-wolf tendencies are a real problem in a team setting and eventually cause so much friction with the family that he's asked to leave. He remains a major character, and Zak never stops looking up to him.
  • Dark and Troubled Past: Was separated by his family at a very young age and got kicked around from orphanage to orphanage. Ended up falling into crime, which is where the Saturday family found him.
  • Delinquent Hair: A red mohawk, although it's never seen fully spiked.
  • Fiery Redhead: Red hair to match his impulsive and reckless attitude.
  • Foolish Sibling, Responsible Sibling: The Foolish to Drew's Responsible. After he joins the family, his recklessness becomes a point of contention.
  • Heel–Face Turn: He was a mercenary for hire under Van Rook's tutelage and Argosts' employ, but Zak prompted him to look up Argost's motives. He didn't like what he found.
    Doyle: Turns out he's got some ideas I'm not so big on.
  • Hidden Depths: Doyle, for the most part, is devil-may-care and more street smart than book smart, but he manages to "improve" on some of Doc's gadgets, showing that he's inherited some of his sister's genius.
  • Hot-Blooded: It seems to run in the family.
  • Jerk with a Heart of Gold: Smart-mouthed and cocky, he has trouble getting along with others, as a result of his Dark Andtroubled Past. However, he immediately latches onto the idea of family, and he'd do nearly anything for his nephews.
  • Leeroy Jenkins: Doyle prefers the term "improvising." Doc points out that this is a very dangerous flaw to have when working in a team, and is one of the major reasons he asks Doyle to leave.
  • Meaningful Name: Like Drew's, his name is Gaelic.
  • Mr. Fanservice: He's handsome and he knows it.
  • The Nicknamer: Likes to give playful nicknames - the ones aimed at Zak are friendly; the ones aimed at Doc, not so much.
  • Obnoxious In-Laws: Doyle is this to Doc. His Hot-Blooded, lone wolf tendencies make him a dangerous variable when they're acting as a team, he's bad influence on Zak, and more than that, Doyle's stories are scientifically inaccurate. Doc comes around to him after they've put some distance between each other, with Doyle striking out to work on his own.
  • Papa Wolf: He's protective of his nephew.
  • Pre-Asskicking One-Liner: So much so that even Zak gets tired of them.
    Zak: Does your brain actually think in cheesy one-liners?
  • 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.
  • Street Urchin: He was one of these for most of his youth, and it's probably how he got his start in the mercenary business.
  • Strong Family Resemblance: Much like how his sister looks near-identical to their mother, Doyle looks near-identical to their father, as seen here. Drew even comments that seeing Doyle's face was like looking at her father's.
  • Token Evil Teammate: Post-Heel–Face Turn. Doyle isn't "evil," but he does have shady morals and maintains a position on several countries' wanted lists.

Enemies

    V.V. Argost

Click here to see him unmasked. 
Voiced by: Corey Burton
"Greetings and bienvenue! I am V.V. Argost, your most grave and gracious host."

V.V. Argost is the host of TV's Weird World, a show that looks like a mix between Ripley's Believe It or Not! and Tales from the Crypt. This show is massively popular worldwide, owing to Argost's natural penchant for showmanship.

He is a megalomaniac, the Saturday family's arch-nemesis, and seeks out Kur in order to use its powers to Take Over the World.


  • Ambiguously Human: The white hair, pointed fingers, and hunched posture make it hard to tell if he's human or not, especially since his entire body is covered in gloves, cape, boots, and mask. He's not, as it turns out.
  • Arch-Enemy: To the entire Saturday family, each member for different reasons. Doc lost several of his friends to Argost during the first assault on Weird World; he murdered Drew and Doyle's parents. Zak averted this for much of the show, since he was a fan of Weird World, but when Argost absorbed the powers of antimatter Kur, Zak became the only one who could stop him.
  • Back from the Dead: In the crossover, 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. It's likely he does this because he's emulating Kur, who is stated to be able to raise and control a cryptid army.
  • Big Bad: Argost is the overarching antagonist of the whole 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 nonchalantly mentions that he "can't remember every individual scream."
  • Catchphrase: "Greetings and bienvenue!"
  • The Chessmaster: Always one step ahead. While he's also a skilled fighter, what he's known for is his cunning.
  • Dark Is Evil: Wears a sinister cloak that's pitch-black inside.
  • Depraved Kids' Show Host: He hosts a television show called "Weird World." While the flair for the dramatic stays the same both on and off-camera, he's murderous and sadistic when the cameras aren't rolling.
  • Evil Is Petty: Admits himself that he's a petty person, often seen taunting enemies or dishing out Disproportionate Retribution. When he isn't thinking straight, he'll prioritize the suffering of his enemies over smarter options, like retreat.
  • Evil Mentor: Is one of these to Zak in Season Two, offering to teach him about his Kur powers. He goes so far as to outright state that he will attempt to betray and/or kill Zak as soon as he's outlived his usefulness.
  • Expressive Mask: He wears a mask, which appears to allow for mouth movements. Many fans did not realize he was wearing a mask for long periods of the show.
  • Faux Affably Evil: He acts overly dramatic and maintains a friendly charisma even as he threatens to force-feed acid to a cryptid or tear someone limb from limb. He'll quickly switch to being murderous if something gets in his way.
  • From Nobody to Nightmare: Argost used to be a nameless yeti in the Himalayan Mountains before becoming an infamous villain and famous TV show host.
  • Gratuitous French: His speech is often peppered with French. Case in point, his Catchphrase above, which he announces himself with every opportunity he gets.
  • Hoist by His Own Petard: In his mad grab for power, he attempts to absorb Zak's Kur while already harboring anti-matter Kur. Since reality is torn apart when matter and anti-matter collide, this results in Argost exploding.
  • It's All About Me: His core motivation. Argost craves recognition and audience, and the ultimate form of this is ruling humanity with Kur's incredible power.
  • Knight of Cerebus: Once Argost makes the scene, things always 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 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 probably where he got his affectation and Large Ham tendencies.
  • Made of Indestructium: His cloak, made from megatooth shark skin, has let him survive fire blasts and explosions with nary a scratch.
  • Manipulative Bastard: Regularly manipulates the Saturdays in order to get what he wants.
  • Never My Fault: Part of his megalomania.
    Argost: Munya, I am loathe to admit we are losing this fight. Naturally, I blame you. Please fly us home to hide your shame.
  • Power Nullifier: Word of God says that Argost's mask is made of a special substance that block's Kur's power, preventing Zak from identifying him as a cryptid until it's too late.
  • Putting on the Reich: When he has Fiskerton captured, he taunts the Saturday family on Weird World while wearing a faux-Gestapo uniform.
  • Serial Killer: As a yeti in the Himalayas, he would regularly murder hikers on the mountain and take trophies back to his cave. His list of victims includes Drew and Doyle's parents.
  • Shout-Out: His first name, Vincent, and much of his mannerisms, are a reference to Vincent Price.
  • The Sociopath: Argost has absolutely no empathy for anyone and only cares about garnering power for himself. Zak calls him out for it, stating that Argost knows nothing of personal sacrifice.
  • Villain with Good Publicity: Thanks to his popular TV show, Argost has gained a huge number of followers. A town of people even turn on the Saturdays, throwing rocks and garbage at them, when they start fighting Argost in public.
    Doyle: Hey, we're the good guys! Los...buenos...guys!
    Argost: But, my dear boy, I'm a celebrity.
  • Villainous Breakdown: Has a savage one after Zak delivers him a beating inside the Antarctica cryptid. He goes from a collected gentleman to raving madman, ordering Munya to make the Saturdays suffer even at the cost of his life. He suffers a greater one in the season finale when Zak starts winning against him in the cryptid war, making him first more susceptible to Rani Nagi's manipulations, and then rushing to boost his own power by stealing Zak's, a move which ultimately kills him.
  • White Hair, Black Heart: Has white hair and is the Big Bad.
  • Would Hurt a Child: Argost has no qualms about injuring or attempting to murder Zak.
  • 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.

Voiced by: Fred Tatasciore
Munya is V.V. Argost's silent and mysterious manservant. When the chips are down, he's capable of using DNA injectors to transform into a half-spider monster with super strength and web-slinging powers.

Although he's silent, he seems to have a bit of his master's sadistic streak in him, as he's quite happy to cause the Saturdays grievous bodily harm.


  • All Webbed Up: His most notable power; he shoots webs out of his mouth. Zak even snarks about this to taunt him.
    Zak: All the spiders I know shoot webs out of their butt. What does that say about your face?
  • Animal Motifs: Spiders.
  • Bio-Augmentation: He gets his spider powers via DNA injectors filled with the DNA of the Papuan giant spider.
  • Body Horror: His transformation into a hulking spider monster features a grotesque transformation sequence where the legs burst through his suit while he shouts in pain.
  • Beware the Quiet Ones: Munya is a silent and ruthless underling for Argost.
  • Ceiling Cling: He gets one of these in the crossover. Could do this at any time, since as a half-spider, he's able to climb up smooth surfaces no problem.
  • Enemies List: See Gotta Kill Them All below.
  • Gotta Kill Them All: Has individual tokens for the Saturday family during their assault on Weird World, which he discards one by one as he disposes of them. When Doc shows up, in order to give him one final taunt before passing out, Munya dumps the rest of them into the garbage.
  • High-Class Glass: Wears a monocle when in his normal human form, to complete the aesthetic he has as Argost's butler/manservant.
  • In a Single Bound: One of his abilities.
  • The Quiet One: Hardly ever speaks, and when he does, it's grunting.
  • Transformation Sequence: Has one when he turns into a spider.
  • Undying Loyalty: It's never explained exactly what his relationship with Argost is, but he's even willing to go against orders to keep Argost safe.

    Leonidas Van Rook 
https://static.tvtropes.org/pmwiki/pub/images/2_08.png
Click here to see him unmasked. 
Voiced by: Corey Burton
"I told you, two is plenty! The other six come out of your pay."

Leonidas Van Rook is a mercenary for hire most often seen in the employ of V.V. Argost, although he does take on freelance work and treasure hunting on his own.

Cutthroat and greedy, he cares only about the money and doesn't ask questions. He dated Drew in college.


  • Adventure Archaeologist: He sometimes excavates tombs and ancient ruins for artifacts to sell. Considering Drew majored in archaeology and they dated in college, Van Rook may have some actual education as an archaeologist.
  • Dying Declaration of Love: "Ah, Drew...you were the only thing I liked almost as much as money."
  • Even Evil Has Loved Ones: Van Rook may be a mercenary but he has a soft spot for Drew, whom he sacrifices himself for.
  • 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. He's also disgusted by Piecemeal and unhappy about being forced to work with him.
  • Greed: He only does thing for the money.
  • Heel–Face Turn: Joins Doyle in Season 2 after Abbey steals his business from him.
  • Helmets Are Hardly Heroic: He sports a helmet for almost all of Season 1, and plays an actively villainous role. When he has a Heel–Face Turn to join Doyle on team Saturday, he stops wearing the helmet altogether.
  • Heroic Sacrifice: He goes out sacrificing his life to save Drew.
  • Husky Russkie: His English is better than most examples, but he's a big, strong Russian man with an accent, who's not always the most competent at his job.
  • 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.
  • Not So Different: Has one with Abbey in the comics, where he tells her that they're both Only in It for the Money, with the only difference being that he sells to the highest bidder and she sells to museums.
  • Only in It for the Money: He doesn't ask questions from the guy with the money, whether that's Argost or Doyle.
  • Psycho Ex-Boyfriend: He and Drew dated for a little while back when they were in college — he still has feelings for her, since he still flirts with her even now that she's married with a child. She claims that she didn't know he was "like that" while she was dating him.
  • The Scrooge: Miserly, always yelling at Doyle about wasting money, and his computer password contains a dollar symbol.
  • Would Hurt a Child: Leaves Zak to get eaten by the Amaroks.
    Doyle: That's cold.
    Van Rook: That's business.

    Zak Monday 
https://static.tvtropes.org/pmwiki/pub/images/2_24.png
Voiced by: Sam Lerner
"You hurt me. So that means I get to hurt you. Beg me to stop."

Zak Saturday from an alternate dimension within Tetzcatlipoca's smoke mirror. For all that Zak Saturday is friendly and kind, Zak Monday is in equal measure cruel and sadistic.

He and his family emerged from the smoke mirror after Zak activated it by touching it, and they consider the Saturday's world to be ripe for the picking, as the Mondays are already wanted criminals in their own.


  • Ax-Crazy: WAY less composed than his good counterpart. He's extremely cruel and sadistic, actively torturing cryptids and going on rampages for fun.
  • 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 Doppelgänger: No points for 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.
  • Sadist: To such a degree that even Komodo Monday comments that he's a "twisted" individual.
  • Slasher Smile: His default expression.
  • Shown Their Work: The Mondays come from the dimension within Tetzcatlipoca's smoke mirror - the "Smoking Mirror" being one of Tetzcatlipoca's epithets. Their world is gloomy and dark, which is a reference to how Tetzcatlipoca's stint as the world's sun was a failure - Tetzcatlipoca's sun was black and only gave off half the light of our current sun. Antimatter and matter also do not get along, although the show takes some Artistic License – Physics in making reality fall apart - what actually happens when matter collides with antimatter is that it explodes, all the mass converted into energy. Kind of like what happened when Argost absorbed regular Kur while harboring antimatter Kur at the end of the show. The mirror itself is made of polished obsidian, as Aztec mirrors actually were.
  • Smug Snake: He always has a smile even when he's losing.

    The Mondays 

The Mondays are the Saturdays' evil antimatter duplicates from a parallel universe, summoned by the Smoke Mirror of Tezcatlipoca. They are criminals in their reality with bad PR. Each Monday has a distinguishing characteristic that sets them apart from the Saturdays.

Being made of antimatter, if they get too close to their matter duplicates, reality begins to fall apart.


    Pietro "Piecemeal" Maltese

Voiced by: Jess Harnell
"Stop struggling! [slurp] You're making the meat tough..."

A criminally insane man who maintains a list of the world's most rare and exotic creatures so he can hunt them down and eat them. To this end, he's surgically modified his jaw to open outward, and is capable of biting through metal.

On his list is the Fiskerton Phantom, and his major motivation in his appearances is to hunt down the family's own and get a taste.


  • Ax-Crazy: Will stop at nothing to get his jaws on the animals on his list.
  • Body Horror: Had his jaw surgically altered so that it can open wide...real wide.
  • Extreme Omnivore: He's seen chewing through and potentially swallowing metal; his stated goal is to eat the rarest and most exotic animals on earth.
  • Shout-Out: To B-list horror movie monsters, of which creator Jay Stephens is a huge fan.
  • Would Hurt a Child: Doesn't matter how old you are; if you're standing between him and an animal on his list, he'll remove you by force.

Allies

    Ulraj 
https://static.tvtropes.org/pmwiki/pub/images/char_39722.jpg
Voiced by: Adam Wylie
"I like to think I am not just a king for my own people, but for all people."

The young prince of Kumari Kandam (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. When he's on the clock, he speaks with royal gravitas; when he's off the clock, he's like a rowdy big brother.

Although he is seen acting as an actual king for his people, generally they're so peaceful that he can afford to take breaks to act as a playmate for Zak.


  • Artistic License – Biology: Claims to have the shark-like ability to sense animals around him through electrical fields. Sharks actually do have this ability, but it only works because water conducts electricity so well; Ulraj can apparently use this trick even while on the surface.
  • Casanova: Apparently, any Kumari girl would trade their left gill to be seen with him. He also flirts with Wadi in order to make Zak jealous.
  • A Child Shall Lead Them: Becomes the King of Kumari Kandam after his father's death. Fortunately, the Kumari are so peaceful that he doesn't seem to have that many responsibilities.
  • 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 arrogant, but he's fun-loving, reasonable, and an overall nice guy.
  • Omniglot: Ulraj knows 14 surface languages, including French and English.
  • Orphan's Plot Trinket: The medallion his father passes onto him shortly before dying. It's one of the keys to Kur's tomb.
  • Rightful King Returns: His introductory episode is about reclaiming his throne from Argost, after Argost took over by staging an attack on Kumari Kandam that killed Ulraj's father.
  • Royal Brat: Downplayed. He's a prince (later king) and has a haughty attitude, but he's a nice guy. See his character quote.
  • Royals Who Actually Do Something: He rides a sea serpent! And deposes Argost from the throne, and saves the planet from the naga threatening to pull out the Atlas Pin.
  • Shown Their Work: Kumari Kandam is a mythical lost continent that would have connected India, Madagascar, and Australia.
  • You Killed My Father: His initial motivation. However, despite still wanting Argost taken down, he decides against taking revenge when he realizes the personal cost.

    Wadi 
https://static.tvtropes.org/pmwiki/pub/images/pic_of_wadi__screenshot.png
Voiced by: Liliana Mumy
"Stole? You must be mistaken. I didn't take your...uh, this?"

Wadi is the daughter of Maboul, the leader of a nomadic tribe called the Hassi. They are a group dedicated to protecting the Methuselah tree, the source of the world's water. However, because her group is very traditionalist, they don't teach their secrets to the children.

She is a kleptomaniac and Zak's main love interest, although it's unclear whether or not she's just flirting for fun. After her introductory episode, she vows only to steal in order to reclaim previously stolen objects.


  • Ambiguously Brown: Wadi is of Middle Eastern descent, but it's not exactly stated where she's exactly from. It's possible that she's Bedouin/Bedu, a group of nomadic Arabs that hail from the Middle Eastern and north African deserts.
  • Give Me Back My Wallet: Catches this often, as a result of her sticky fingers.
  • Impossible Theft: She can steal Zak's belt off his waist.
  • Just Like Robin Hood: Her eventual goal is to only steal from people who have stolen things first, so she can return the stolen objects.
  • Karmic Thief: Claims that she will only steal from people who stole things first at the end of her introductory episode.
  • Killer Yoyo: Wadi wields one she calls "The Thieves' Yoyo" in later episodes.
  • Kleptomaniac Heroine: Though she vows by her next appearance that she is reformed.
  • Little Miss Snarker: With Zak on the receiving end of most of her quips.
  • MacGuffin Guardian: ...Or at least she will be, once she grows up and her tribe finally teaches her their secrets.
  • Meaningful Name: "Wadi" is an Arabic term referring to a riverbed that only holds water when heavy rains occur. Considering her introductory episode is about accidentally drying up the world's water, her name reflects her character theming of drought.
  • Puppy Love: Downplayed, with Zak — Both are roughly the same age (starting at 11 and ending at 13) and have crushes on each other.
  • Shown Their Work: The Methuselah tree that her people guard is the name of the oldest tree in the world, which in real life has had its location hidden to avoid vandalism. The scroll she finds in the desert is probably a nod to the Dead Sea Scrolls, and the Methuselah's reworking as a World Tree may be a reference to the Zamzam Well.
  • Single Woman Seeks Good Man: Wadi appears to have a crush on Zak, whom she describes as "chivalrous."
  • Sticky Fingers: "I see it, I want it, I take it. Why is this so hard for you to understand?"

The Secret Scientists

Not pictured: Prof. Talu Mizuki, Dr. David Bara, Dr. Odele, Dr. Grimes, Dr. Lawhorn, Dr. Pachacutec, Dr. Yoshiko
"UFOs, quantum physics, paranormal abilities...anywhere there's a secret left uncovered, they've got somebody working on it."

An international group of scientists dedicated to pursuits that "normal science doesn't believe in," with authority higher than international government. Their mission statement is to discover the secrets of the world before those who would use them for ill have the chance to do so.

They numbered forty before an assault on Weird World to recover the Kur Stone reduced them to seven. Since then, their number seems to have recovered somewhat, although it's unclear exactly how many of them there are now.


  • Badass Bookworm: All the scientists who survived the assault on Weird World (and some of the new ones) qualify, since most of them don't look like fighters, but can still throw down if need be.
  • Crippling Overspecialization: Each scientist tends to only be a supergenius in a single field - but as a team, they're a formidable force.
  • Well-Intentioned Extremist: Once it's revealed Zak is Kur, the Scientist's plan is to cryogenically freeze him indefinitely until a solution can be found. May not be too extreme, considering Kur is poised to destroy all of humanity, but it's definitely an ethically questionable decision.

    Dr. Arthur Beeman 
https://static.tvtropes.org/pmwiki/pub/images/char_39718.jpg
Voiced by: Jeff Bennett
"Noted. I'll let my feelings know they should be hurt."

Dr. Arthur Beeman is a Secret Scientist who specializes in UFOlogy. He's rude, brusque, and snarky, but appears to be the de facto leader for the Scientists whenever Doc's not there.

He broke a Crop Circle code in '03 and saved the Earth from invasion, meaning he's the only Scientist who's been confirmed to have saved the world prior to the story.


  • Ambiguous Disorder: Between his hyperfixation on aliens and his flat monotone, it's implied he might have autism. The glasses he wears may be tinted pink to help mitigate photosensitivity, a common symptom.
  • Babysitter from Hell: He's rude and condescending, but worst of all, he's boring. His idea of fun is logging hours of fake UFO footage at a time, and he wonders why Zak doesn't find it funny.
  • Badass Bookworm: Survived the assault on Weird World and is one of the three Scientists seen fighting the Saturdays in Season 2. Not to mention he owns and drives a flying saucer.
  • Deadpan Snarker: Speaks in a clipped monotone, but every other sentence out of his mouth is snark.
  • Death Glare: Delivers one to Zak when Zak asks if their truce wasn't supposed to be longer.
  • Did You Just Flip Off Cthulhu?: His snark is not limited to human targets. He even fires one off at Rani Nagi, not to mention he's been snarking at Kur all show long.
  • Flying Saucer: Owns and drives one. It's unclear whether or not it's alien in origin.
  • Insufferable Genius: He's a jerk, but he's really good at his job. This, combined with his uncompromising rationality, are what land him such a prominent spot on the Scientists even if no one's really friendly with him.
  • Jerkass: From his condescending nicknames towards Zak to being the least bothered of the Secret Scientists regarding their plan to cryogenically freeze Zak to find a solution for Kur. Word of God says he's "kind of rude with everybody!"
  • Jerkass Has a Point: Mentions that only a few months prior, Doc would have openly mocked the idea of finding a magical solution to Kur. The plan to cryogenically freeze Zak is also viciously opposed by the Saturdays, but the other Scientists agree that it's the best course of action, since Zak's potential bodycount is "all of humanity."
  • Motor Mouth: Only when it comes to his work.
  • The Friend Nobody Likes: While he's on genial terms with the rest of the Scientists and they often look to him for advice, his unfriendly nature does not beget him much goodwill.
    Drew: Okay, he's my least favorite.
  • The Nicknamer: Especially towards Zak, e.g. "Pandahead", "Porcuperm", "Spikeylocks", etc. The only character he doesn't refer to by a nickname appears to be Doc, and Doc is Only Known by Their Nickname anyway.
  • No Sense of Humor: Or at least a very impenetrable one. While he snarks, that seems to be more just how he talks than active joke-telling — what he actually thinks is funny is poorly-made UFO hoaxes. Hours of it.
  • Omnidisciplinary Scientist: His specialty is in UFOlogy, but he's seen decoding a musical scale at a glance. It's likely that he's considered the de facto leader because he's the most intelligent and widely disciplined among the Scientists, as understanding aliens involves a wide array of skills and education.
  • Smart People Wear Glasses: Beeman was capable of decoding a secret, ancient musical code at a glance. He sports a pair of pink glasses.
  • Smug Snake: He's rude to Zak, Doc, Drew, Rani Nagi...but goes down pretty quickly in a fight and is quick to extend the truce when bargaining for the Saturdays to remove the revolving beast from his home in Season 2.
  • The Extremist Was Right: There is no evidence in-show that Kur will not in fact cause the deaths of all humans, and the show ends with Zak losing his powers, so Beeman still may have been right in that Zak was an enormous threat. In fact, Word of God has stated that losing his powers was the only way for Zak to have firmly stayed on the side of good.
  • The Spock: He's valued by the other Scientists for this trait, as he's willing to cast even his friends into doubt if he thinks they're just plain wrong.
    Beeman: That's an irrational dream, Doc. One you would have openly mocked six months ago.
  • Token Evil Teammate: Of the Secret Scientists. It's exemplified by how willing Beeman was to risk giving Argost and Zak a lethal dose of the Flute of Gilgamesh.
  • Well-Intentioned Extremist: The Scientists' plan for dealing with Kur is to cryogenically freeze a child until a "solution" can be found, however long that takes. Beeman seems to be the most unrepentantly on board with this plan, actively taunting Doc about how desperate he's gotten.

Dr. Paul Cheechoo is a Secret Scientist that specializes in cold-climate research, with a penchant for geology. He is almost always seen with a team of other scientists, researching geological movements and activity.

He's good-natured and friendly, and always quick with a witty quip.


  • Canada, Eh?: Dr. Cheechoo is from an unnamed First Nations tribe that hails from northern Canada. It's likely that he's Inuit, since his glasses are traditional Inuit snowgoggles.
  • Cool Shades: Sports a pair of traditional Inuit snowgoggles/sunglasses.
  • Friendly Enemy: After the Scientists turn on the Saturdays in Season 2, Paul is still never seen actively fighting them. He's the one to contact them for help with the revolving beast, starting off with an apologetic "I know this is awkward."
  • Well-Intentioned Extremist: The Scientists' plan for dealing with Kur is to cryogenically freeze a child until a "solution" can be found, however long that takes.

  • British Stuffiness: She's very stiff, even waving off sympathy for her sister's Face–Heel Turn.
  • Do-Anything Robot: Has a robot named Deadbolt that assists her in combat. Despite how much money he costs to maintain and upgrade, he's not all that useful.
  • Hot Scientist: A very attractive Secret Scientist.
  • Meaningful Name: Her last name matches her outfit's color scheme and may be a commentary on the show's themes of Grey-and-Gray Morality.
  • My God, What Have I Done?: She has this moment in the final episode, turning on Beeman and sabotaging his attempt to subdue Argost and Zak with the Flute of Gilgamesh.
    Miranda:I'm sorry, Arthur. But I'm not sure I like what we've all become.''
  • Portal Door: Her weapon of choice is a portal gun capable of generating these in mid-air.
  • Well-Intentioned Extremist: The Scientists' plan for dealing with Kur is to cryogenically freeze a child until a "solution" can be found, however long that takes. Eventually, Miranda decides that pursuing this goal was not worth the cost.

"I stopped them. But the fire destroyed the device! Now I am forced to live out my life as this...beast."

A Japanese scientist who was unwittingly tricked by Shoji Fuzen into creating a body-swapping device, under the impression that it would be used for good. When Fuzen revealed he planned to use it on his soldiers to swap them into the body of a Hibagon, Dr. Mizuki used the device on himself. However, in the resulting fight, his human body and the body-swapping device were both destroyed.

After being talked down from pursuing revenge and given his own lab, he seems to have joined the Secret Scientists, continuing research to recreate the device and one day regain his human form.


  • Baleful Polymorph: Is initially very unhappy with his new Hibagon body.
  • Cool Pet: Has a pet white tiger with the brain of a dog. It's very friendly, and the perfect petting size for his new Hibagon body.
  • "Freaky Friday" Flip: Created a device with this power. The original body (and swapped mind) are put in stasis while under its effects, but since the device was destroyed, Mizuki became stuck in the Hibagon's body.
  • Roaring Rampage of Revenge: Meets the Saturdays during one of these, as he attempts to take revenge against Shoji Fuzen for trapping him in the body of a Hibagaon. He gets talked down by Doc, and then redirects his efforts into recreating the device, using the resources granted to him as a member of the Secret Scientists.
  • Seldom-Seen Species: This is probably one of the first western works to feature the Hibagon, a Japanese cryptid similar to Bigfoot.
  • Wide-Eyed Idealist: At least until Fuzen betrayed him.
  • Well-Intentioned Extremist: The Scientists' plan for dealing with Kur is to cryogenically freeze a child until a "solution" can be found, however long that takes. Mizuki is the one who tries to peacefully convince Doc at the beginning of Season 2.

Other Humans

    Francis 
https://static.tvtropes.org/pmwiki/pub/images/2_124.png
Voiced by: Scott Menville
"Good guys, bad guys, you always know their next move. Victory goes to the gray men in the middle, because you never know how we'll surprise you."

Epsilon's son, Francis is a member of a mysterious group that refer to themselves as the "people." These "people" are self-serving and have unknown, secret agendas, and similarly, Francis is cutthroat, businesslike, and manipulative.

He initially appears to be a shy, anti-social child trying to survive the turbulence of his father's secret world. However, by the end of his introductory episode, it's revealed that Francis is a schemer, an active participant in his "peoples"'s plans, and arrogant to boot. But he really does hate Zak, though. That part wasn't fake.


  • Ambiguously Human: His "people"'s sickly pale skin color and penchant for wearing eye-obscuring goggles makes them appear as though they may not be totally human. Word of God has confirmed that they are human, however.
  • Animal Espionage: His "people" were attempting to do this by controlling atmospheric jellyfish into an all-purpose survaillance and air defense force.
  • Arch-Enemy: Zak considers him to be this in the Field Guide. It's unclear whether or not the feeling is mutual, but Francis really does hate Zak a lot.
  • Cloning Blues: Francis's "people" found their perfect agent 100 years ago, and they've been "repeating" him ever since. Francis himself clearly has some trepidation over the fact that his life has been planned out for him.
    "One day I'll get to be the Epsilon. And I'll have a Francis of my own. And then I can teach him to live up to one hundred years' worth of high expectations!"
  • Code Name: It turns out that "Francis" is the name given to every clone in Francis's series while they're still young.
  • Conspicuous Trenchcoat: It's forest-green, just like Epsilon's.
  • Foil: To Zak. Both of them are children thrust into a world of secrets by their parents, but where Zak tries to do the right thing and cares about others, Francis is morally ambiguous and only cares about achieving his own goals. This is taken to an extra level in Season 2, where it's revealed Francis is a clone of his "people"'s perfect agent, and his destiny, like Zak's, is supposedly set in stone. This prompts a Not So Different from Zak about how others can tell them what they think they're supposed to be, but they can't tell them who they are.
  • Good Is Dumb: He believes that "good guys" and "bad guys" are both predictable, and lambasts Zak for doing the right thing even when it was obvious he would do so, and thus easy for Francis to intercept him.
  • Hates Being Touched: Has an electric force-field that shocks anyone unauthorized, and comments on Zak's lack of "personal hygiene."
    Zak: Will you stop that!
    Francis: But then you might actually touch me.
  • It's Personal: Sure, the anti-social shy kid act may all be part of the mission...but he really does hate Zak. It's later revealed that this may be envy over the freedom and support Zak has in his life, while Francis has been forced into nonstop training to shape him up into the "perfect agent" his "people" expect him to be.
  • Jerkass: Constantly snarky and rude to Zak, outright and openly tells him he hates him, and thinks nothing of manipulating others to achieve his goals.
  • Jerk with a Heart of Gold: After Zak's Not So Different speech, Francis notes how the Lake Van Monster seems to like him, and opts to let him go instead of hold him in place until his "people" can capture him. However, this seems largely motivated by how much he hates Zak, so exactly how nice he's being is up for debate.
  • Magnificent Bastard: Francis tricks Zak and the rest of the Saturdays into believing he's a harmless kid thrust into a scary world. In reality, he's every inch an agent as Epsilon is, and the shy kid schtick was a ploy by the both of them.
  • Not So Different: On the receiving end of this from Zak, who gives him a speech about how people can tell them what they expect them to be, but can't tell them who they are. This causes Francis to let him go free.
  • Overt Operative: He goes by his name, Francis. Subverted in that his "people" appear to exist outside normal society, so knowing his name doesn't help if you're trying to track him down.
  • Smug Snake: Despite how efficient and capable he normally is, he will sometimes flub his mission in order to snark at Zak, and often underestimates him.
  • Preteen Superspy: Francis is eleven and a secret agent. Later on, he's thirteen, and a secret agent.
  • Sinister Surveillance: A neutral example. "Everyone has a file," and what the "people" are doing with those files is completely unknown.
  • Sonic Stunner: His "people"'s weapon of choice is sonic collars that fire high-frequency soundwaves. While these don't seem to kill, they're still an effective weapon against humans and cryptids alike.
  • Tracking Device: Epsilon has Francis's location at all times.
  • The Men in Black: Francis and his "people" appear to be a nod to this. However, it should be noted that they are a group that operates outside of all known governmental structures.
  • Tyke Bomb: He's been trained since birth to be an agent. In fact, he was cloned to be an agent.

    Epsilon 
https://static.tvtropes.org/pmwiki/pub/images/2_78.png
Voiced by: Brian Stepanik
"Everyone has a file."

Francis's father and an agent for a mysterious "people" that has worked with the Secret Scientists before. However, they are unaffiliated with any known organization.

Epsilon is cold and professional, although he maintains a genial tone when talking to the Saturdays. It's unclear what his "people"'s ultimate goal is, but it is clear that they're only in it for themselves.


  • Ambiguously Human: His "people"'s sickly pale skin color and penchant for wearing eye-obscuring goggles makes them appear as though they may not be totally human. Word of God has confirmed that they are human, however.
  • Code Name: Epsilon. However, knowing that he was a clone destined to be an agent from birth, he may not actually have a "real name."
  • Conspicuous Trenchcoat: It's forest-green.
  • Consummate Professional: The only time he ever drops his businesslike tone is when he's berating Francis.
  • The Men in Black: Epsilon and his "people" appear to be a nod to this. However, it should be noted that they are a group that operates outside of all known governmental structures.
  • Sinister Surveillance: Just look at his character quote.
  • Sonic Stunner: His "people"'s weapon of choice is sonic collars that fire high-frequency soundwaves. While these don't seem to kill, they're still an effective weapon against humans and cryptids alike.
  • Tracking Device: Epsilon has Francis's location at all times.
  • Truly Single Parent: He introduces himself as a single parent, but it's not until Season 2 that it's revealed how true that is: he and Francis are the latest in a long line of serial clones.

    Abbey Grey 
https://static.tvtropes.org/pmwiki/pub/images/2_39.png
Voiced by: Kari Wahlgren
"I can't believe I babysat a real Lemurian! How'd you keep it secret for so long?"

Zak's old babysitter, and Miranda Grey's younger sister. Abbey is an archeologist whose dayjob is retrieving ancient artifacts from booby-trapped tombs, and specializes in ancient, lost civilizations.

Her help is called upon in order to uncover the secrets of the Lemurians, whereupon Doyle begins to date her until she has a Face–Heel Turn and takes on a job as Van Rook's new apprentice.


  • Adventure Archaeologist: Her calling, and why her specialty is lost civilizations.
  • All Girls Want Bad Boys: Thinks Doyle is charming.
    Abbey: My. You are dangerous.
    Doyle: Like a hurricane, baby.
  • Cain and Abel: A rare younger Cain, her sister is a doctor and a member of the Secret Scientists, while Abbey has the considerably less glamorous title of Zak's babysitter. Her sister's success and renown compared to her own may be a factor in her eventual Face–Heel Turn.
  • Dark Is Evil: Black hair and black makeup, her design makes her out to be a lot darker, especially when compared to her sister. And then she turns on the family...
  • Chronic Backstabbing Disorder: Betrays the Saturdays and the Secret Scientists to join Van Rook, and then betrays Van Rook and steals his business.
  • Evil Brit: Her accent and that mask go together quite well.
  • Evil Former Friend: To the Saturdays. She used to be Zak's babysitter.
    Zak: And you threw it all away for money.
  • Face–Heel Turn: Abbey betrays the Saturdays to go work for Van Rook.
  • Meaningful Name: Her last name matches her outfit's color scheme and may be a commentary on the show's themes of Grey-and-Gray Morality.
  • Not So Different: Van Rook gives her one in the comics, stating that the only difference between them is that she sells to museums and he sells to the highest bidder. This becomes true, much to Van Rook's detriment, when Abbey is such a natural at the mercenary game that she ends up stealing his business from him.
  • Only in It for the Money: She used to sell the artifacts she recovered to museums. After her Face–Heel Turn, she outright says that it's not personal, it's money, as she attempts to get the Saturdays killed.
  • Relationship Upgrade: Starts dating Doyle at the end of her introductory episode.
  • The Apprentice: Takes Doyle's place as apprentice to Van Rook. And then she steals his business.

Cryptids

    Kur 
https://static.tvtropes.org/pmwiki/pub/images/kur_stone.jpg
The Kur Stone, a map to Kur's tomb and the closest we ever get to seeing it.
An ancient Sumerian cryptid of incredible destructive power who is said to be able to raise a cryptid army. In the show's mythology, it appears to have been alternately worshipped as a god and slain as a monster.

Argost seeks to find it in order to control it, and thereby control the cryptid army it raises, in order to Take Over the World. The Saturdays are trying to find it first in order to prevent that from happening.


  • Informed Attribute: Kur is said to be "the ultimate evil," but why everyone believes this and what Kur is supposed to have done is never shown or explained in much detail. The only sources we have that give any kind of information at all on its supposed history of destroying civilizations are Argost and Rani Nagi, both of whom have their own agendas and are hardly the most credible.
  • Living MacGuffin: The entire first season is just one long journey to find it before Argost.
  • Posthumous Character: In a way. Argost and the Saturdays go out of their way to find its location, only to discover its tomb. It's actually been reincarnated as Zak, but for all intents and purposes, whatever personality Kur had is dead.
  • Psychic Powers: Seems to have wielded some kind of psychic control over cryptids.
  • Sealed Evil in a Can: Supposedly the Kur Stone can lead those who have it to Kur's location. It turns out that the Kur Stone itself held the sealed evil, as Kur's soul inhabited the Kur Stone until it was unearthed by Doc and Drew's archeological team. It then jumped to Drew's unborn son.
  • Shown Their Work: "Kur" in Sumerian references a great many things, including the Underworld itself. At the time the show was created, it was also believed to be the name of the first mythological dragon, often depicted as serpentine. Kur's tomb is a reference to the Koh Ker archaeological site (the Field Guide lists the tomb's name as the Kohker Temple), a temple dedicated to Shiva, a Hindu deity that destroys the world. Of her symbols, one is a cobra around her neck, which references her control over all the animals on earth, and the other is a trident, which bears an enormous visual similarity to the dowsing rod/tuning fork that Fiskerton's lemurian instincts compell him to create. All in all, the connotations of the real-life mythologies Kur references paint the picture of something that's very bad news.
  • Shrouded in Myth: Despite its importance to the plot, we actually learn very little about it. Kur was evidently sort of cryptid that lived 4600 years ago and was supposedly defeated with the Flute of Gilgamesh; all else is very much hearsay and unreliable sources. The legends that remain describe him as evil, in any case.
  • Soul Jar: The Kur stone was a soul jar for Kur, until it was unearthed.
  • Villainous Legacy: Although the sources are unreliable, Kur has apparently "laid waste to civilizations," and is destined to destroy humanity. Its immense, legendary power inspired Argost to seek it out, kickstarting the whole plot. Argost sums it up best:
    Argost: There's a reason there are no happy, heroic stories about Kur.

    Rani Nagi 
https://static.tvtropes.org/pmwiki/pub/images/1_31.jpg
Voiced by: Susanne Blakeslee
"Arrogant ape creatures...you think you're smarter than a queen?"

Rani Nagi is the queen of the naga, a race of serpentine cryptids that directly served and worshipped Kur. Cunning and more than willing to resort to drastic measures to get what she wants, she is a formidable opponent.

Her desire is to ally with Kur and kill all humans (and possibly all intelligent life aside from naga-kind).


  • The Beastmaster: One of the naga's abilities is to control snakes. This ranges from standard-issue venomous cobras to the Kumari's sea serpents.
  • The Corrupter: Attempts to do this to Zak, and later succeeds in doing this to Argost.
  • The Dragon: Sets herself and her race up as this.
  • Dragon with an Agenda: It becomes clear pretty early on that she values Kur more as a force for destroying all humans than she values what Kur actually wants.
  • The Dreaded: The mere mention of the naga sends Ulraj quaking in his boots. They were known as the "scourge of the ancient world."
  • Genocide Backfire: Seems to be what happened to them, as Ulraj states they were supposed to have been wiped out "centuries" ago. Unfortunately, there were survivors.
  • God Save Us from the Queen!: Rani Nagi means "queen of the nagas" in Hindi.
  • Kill All Humans: The naga's real goal. Note that this may not be limited to humans; the naga seem opposed to every intelligent species besides their own.
  • Manipulative Bastard: Rani Nagi manages to ingratiate herself with Argost, eventually taking advantage of his Villainous Breakdown to convince him to change goals from ruling the humans to massacring them.
  • Religion of Evil: They worship Kur, and - according to Rani Nagi, at least - Kur's destiny is to destroy all humans.
  • Shown Their Work: The naga are seen at one point shooting fireballs out of the river. This is a reference to the naga fireball phenomenon along the Mekong river.
  • Snake People: The naga as a whole.
  • Sssssnake Talk: Rani Nagi drawls her S's and intersperses her dialogue with hissing.
  • You Killed My Father: Although Rani Nagi promises to help Zak's family fight off the Scientists, she immediately abandons them to their fates in order to invoke this trope.
    Rani Nagi: Give the boy a tragedy to avenge.

    Tsul'Kalu 
https://static.tvtropes.org/pmwiki/pub/images/2_65.png
A mystical, honorable hunter who serves as the guardian for the sacred Judaculla rocks. When Zak accidentally destroys one as a child, Tsul'Kalu hunts him down to make him pay for it.

It is the Hand of Tsul'Kalu, a mystic artifact he carries, that sits at the end of Zak's claw. In Season 2, he comes to get it back.


  • Beast Man: Sentient, intelligent, and humanoid, but not exactly human.
  • Classical Hunter: This is how he's described.
  • Disproportionate Retribution: Given that he's a cryptid, Tsul'Kalu may not think of it as disproportionate, but he was willing to fight and potentially kill a child for destroying one of his sacred sites.
  • MacGuffin Guardian: He guards the Judaculla rocks.
  • Nature Hero: A noble hunter, in touch with nature.
  • Psychological Torment Zone: Inflicts this on Zak via their connection through his powers, showing Zak a future where Zak's turned evil and is actively trying to destroy all of humanity. Zak initially thinks he's being shown his own worst fear, but it's actually Tsul'Kalu's.
  • Scarily Competent Tracker: Manages to track the family from North Carolina all the way to the Pacific coast.
  • Shown Their Work: Tsul'Kalu is a Cherokee mythological figure known as "The Great Lord of the Game." The Judaculla rocks he guards are also sacred to the Cherokee.
  • The Voiceless: Tsul'Kalu doesn't talk - he doesn't even grunt.
  • Wild Man: Fights with hatchets, blowdarts (that explode), and bolas.
  • Worthy Opponent: With Doc, after Doc bests him in a fight. As a show of honor, Tsul'Kalu gifted him with the Hand of Tsul'Kalu.
