- "Zak... is Kur."
- ―Doc Saturday
Zak is lean built and average height and weight for his age but is shown to have somewhat above average strength. He has either a sweet smile or a cocky grin throughout the series. Zak has black hair, eyes and dark brown skin from his African-American father, but Caucasian features and a shock of white blonde hair from his mother. His clothing consists of yellow sweatpants, an orange shirt with an "S" on the front (although it resembles a distorted silhouette of The Claw), and a black undershirt. It was shown that he wears white brief underwear.
In T.G.I.S., he looks almost the same as before. He retains his salt and pepper hair style and skin tone. However, his hair is now longer and he also sports three freckles on each cheek. Along with that, he now wears the same armor as his parents. He is also significantly taller.
Zak is sometimes viewed as being reckless and irresponsible, but this is partly because he believes that his parents are babying him, and thus tries to prove himself.
He is also quite smart and caring for cryptids and his family. He has always felt close to cryptids, as seen when he comforts Fiskerton when he adjusts to life with the Saturdays, protecting him from Komodo, and welcoming in Zon, as well as setting free numerous cryptids in Cryptids Vs. Cryptids, and again in the Unblinking Eye. His intelligence shown when he managed to outsmart Argost, whom calls himself the world's most dangerous mind, by "Influencing" Munya, something that Argost didn't even think would be possible. He is also a capable strategist, managing to hold his own against Tsul Kalu without a scratch or permanent damage, something which Doc did but came back with an electrified hairdo, and one blind eye.
After learning that he is Kur, Zak started to be less confident, and started to think and fear he might turn evil.
He is also 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.
Powers and AbilitiesEdit
- Main article: Zak's Power
- Zak is mentioned being 12 in Kur Part 2, which means that he is at the stage of his life between a child and young adult. The chemical and biological changes within Zak could be affecting his powers, and once he grows into an adult his powers could develop even stronger.
- Zak is brought up to believe that Kur is evil, and his powers are good. But now he has discovered that his powers are from being Kur, Zak may subconsciously believe using his powers will send him down a path of evil. Therefore, deep down Zak may not even want his power anymore.
- In Life in the Underground, Zak is able to blow two giant Calopus away at the same time when his body and eyes are glowing orange while the others can hardly hold up against one. This causes him to faint and proves that his Kur power provides him strength that goes beyond human ability, even surpassing the strength of Doc (who can lift a giant rock), Drew (who can throw a really big TV screen), Ulraj (who can hold up against a 250-pound Komodo dragon), Fiskerton (who can jump off the flying Airship onto the Argost's warship safely), and Wadi.
- He does not have his "power" anymore but it could be that Zak's powers are too weak to be used at the time after be nearly drain because Zak could not live without his cryptid counterpart. It is later confirmed to have been weakened at the time as shown in T.G.I.S. That he still holds some form of telepathy and communication with the cryptids around him.
- Even without his power Zak is still a formidable hand-to-hand combatant as he has beaten opponents with more combat experience than him such as; V.V. Argost, Doc Saturday and Tsul'Kalu.
The Secret SaturdaysEdit
Zak Saturday is the 13-year-old (as of Life in The Underground) son of Doc and Drew Saturday who is eager to jump right away into every adventure. He is a mulatto, which means he has a mixed heritage which is obvious by his half-African American skintone. A product of his environment, Zak seeks adventure at every turn, which is easily satisfied by his cryptid-researching family. He has an unorthodox upbringing that has taken him around the world and placed him in the face of danger since the day he was born. He is voiced by Sam Lerner.
Zak was born the same year the Kur Stone was found. Zak has a special psychic ability to connect with cryptids, allowing him to control their actions to an extent as well as communicate psychically in their minds. Tamer cryptids seem to trust him instinctively, and even fiercer ones can tell that Zak is different from other humans. It was also suggested by Ulraj in The Underworld Bride his power is only effective if the cryptid Zak is trying to influence at least partially wants to do what Zak is trying to get it to do. His parents believe that with Zak's ability, he would be the only one with the power to stop Kur, a legendary cryptid said to be able to control all cryptids. In Kur Rising, the Antarctic cryptid obviously didn't want to be defeated and spend another millennium in Antarctica, but Zak was able to control that giant cryptid even when he hadn';t awaken as Kur yet. This may hint at how powerful Kur really is. Ancient artifacts seem to respond to Zak and allow him to amplify his ability.
Zak's primary weapon is The Claw, a combination short staff/grappling hook. The hook is a three-fingered claw called The Hand of Tsul 'Kalu which acts as a focusing device for Zak's powers, and a probable thunderbird claw due to Tsul 'Kalu shocking Doc with it in the flashback in the Return of Tsul 'Kalu episode. His power can be amplified if Zak is at a "mystic hotspot," a place infused with magical energy, like inside the Antarctic Cryptid. After he uses his power at a mystical hotspot, he becomes drained and possibly exhausted. He also seems to have the ability to make a wind-like aura around his body in Cryptid vs. Cryptid and an orange energy ball in Kur Rising.
Zak can control his powers with great concentration. In The Atlas Pin, he meditates with Drew and Fisk to stop the giant serpent of Kumari Kandam. In Shadows of Lemuria, when he is very close to the revealing and the relic, he could get in Fisk's brain and get rid of the parasite. In The King of Kumari Kandam there is the Royal Medallion of Kumari Kandam, which had this lyric: "Before the breath of Kur the sentinels will fall." If that thing really holds a part of Kur, it could make Zak even stronger than now.
He is of mixed-race heritage since he has a black father and a white mother. He has some appearance of both, like dark skin from his father and Caucasian features and a white streak of hair like his mother. Zak cares deeply for his cryptid "pets"/companions and even refers to them as his brothers and sisters. This corresponds to his bond with cryptids and possibly influences his cryptid powers. Zak also seems to be stronger than a normal child his age, as he is able to climb a radio tower carrying a full grown man in The Vengeance of Hibagon and gets back up immediately after being thrown against a vent in Black Monday.
During the course of the show, his strength has improved. Also in Black Monday, Zak is able to hold his own against the three Monday cryptids and even slams Zon to the ground in the second episode, The Kur Stone: Part Two. No one was a physical match for him.
In Ghost in the Machine Zak has also fused with his brothers because of a machine created by former scientists in a lab on Honey Island. Because of this, he temporarily gains Fiskerton and Komodo's abilities. This version of Zak has trouble thinking because of having three brains. After this experience, Zak says that the three of them have gotten even closer and are now "DNA brothers." The machine was later destroyed by the Saturdays.
In The Kur Guardian, Zak, Doyle, and his old babysitter, Abbey Grey help Fiskerton find out more about Fisk's Lemurian heritage. Doyle and Fisk had kept the information secret at first but decided to share it with Zak because Zak is the only one Fisk trusts completely (Doyle learned the info from Rani Naga when he over heard her talking with V.V. Argost when he and the Saturdays were rescuing Fisk from Weird World).
In Shadows of Lemuria, Zak finds out Fisk is making trident-like shapes at every available moment. Fiskerton tells Zak he kept it secret because he is "scared for him." Later, Argost smuggles a Neural Parasite into the Saturdays House which eventually lands on Fiskerton. Fisk tears the house apart to create a divining rod that will reveal where Kur is, which happens to be Antarctica which Argost found out through the Parasite. Despite the fact that the madman V.V. Argost is his enemy, prior to Kur Rising, Zak was a fan of his show Weird World, and kept episodes on the main computer. In the Season One finale, Zak and his family go to Antarctica. Unfortunately for them, Argost is also there and has awakened the creature which is believed to be Kur. Argost manages to get to the beast's brain and controls it from within. Zak then gets the idea to also enter the cryptid';s body and fight Argost for the controlling of "Kur." His parents give him their weapons so he could have as much power as possible in the battle with Argost. Fiskerton follows Zak inside and aids him in the fight. Zak taps into his full power to defeat Argost and knocks the Antarctic Cryptid unconscious.Doyle then uses the Naga Kur Detector to confirm what they just defeated is Kur. However, once Zak and Fiskerton are expelled from the body, the artifact glows not in the creature's presence, but in Zak's. Everyone, including Zak, is shocked by this. The show's creator, Jay Stephens, has revealed that Zak is Kur reincarnated.
In the Season 2 first episode, Kur: Part 1, the Secret Scientists discover Zak is Kur. The family soon become fugitives. While the Secret Scientists are tracking him, Zak realizes his family is in danger. To make matters worse, the Nagas are also after Zak to lead them and all cryptids into a new era. Meanwhile, Doyle has a run-in with Leonidas Van Rook.
In Legion of Garuda, the Saturdays learn a sect of sorcerers were able to drive out the spirit of Kur in the past and begin looking for the group. They eventually meet Gokul, the head master of the legion, who tells them Kur can be driven out by using an artifact known as The Flute of Gilgamesh. It turns out the Nagas stole the flute centuries ago to protect Kur. But when the Saturdays locate the flute and let Gokul use it, they also find out that using it would kill Kur (Zak). The Saturdays, the Secret Scientists, and the Nagas save Zak, and the sorcerer disappears. When they all leave, Argost comes to where they had left the flute, and takes it.
In The Return of Tsul 'Kalu Zak goes to fight Tsul 'Kalu, after he returns to get the Hand from the end of Zak';s Claw. Zak gives up the Hand easily, but Tsul 'Kalu refuses it and wishes to fight for it honorably as a hunter. Then Zak begins to see visions of the dark future, every time he uses his powers on Tsul 'Kalu. In the end, Zak realizes these visions weren't his, but the hunter's fears. Zak gives up the Claw, saying that Tsul 'Kalu should take it back because, if even the good cryptids think he is destined for evil, he obviously doesn't deserve it. But then Tsul 'Kalu realizes that Zak is good inside, and leaves the Claw and parts ways with him.
In The Unblinking Eye, Zak is chased down by Epsilon and Francis to be recruited by their "people." When first escaping them easily, Zak convinces his parents to help a cryptid like they normally do. They track a Lake Van Monster in Istanbul, in a power plant. Soon Epsilon's people track Zak, and start to chase him wildly. Francis gets Zak, but unknowingly reveals a satellite is tracking their every move (later revealed to be the Rani Naga's relic which the "people" stole from Doyle strapped to a satellite). Doc and Drew go to space to disconnect the satellite, while Fisk, Komodo and Zak calm down the Lake Van Monster. Francis finds them and gets into a family feud argument with Zak. Francis suddenly shouts that Epsilon isn't his father. Zak suddenly pities him, after realizing Francis and Epsilon are clones. After a short time, Zak states that the Lake Van Monster doesn't care about labels, and Francis decides to let him go, which hints there might be a spurred friendship between them...even though their "goodbyes" were Francis saying "I guess it's a good thing we hate each other so much, huh?" and Zak replying with a smile: "I never wanna see you again, too, Francis.".
In Life in the Underground, Zak's birthday party is filled with surprises including a visit from Ulraj and Wadi. The Saturdays find out a town is being attacked by cryptids. When the Saturdays come to investigate they are attacked by some Kalabus. Zak, Wadi and Ulraj go underground with the cryptids, and cause a rockslide. Zak, Wadi, and Ulraj were being buried alive, Zak remembered Argost's words and managed to summon one of the cryptids to save them. Zak realizes he can control cryptids no matter the distance between him and them. They find out that the cryptids were making a survival colony to save themselves from Kur. Zak's crush on Wadi and hers for him is more obvious in this episode; for one thing, Wadi kisses Zak on the cheek. Zak returns to the clock tower to thank Argost, who then gives Zak a neural parasite to contact him with should the need arise despite Fisk's objections.
In And Your Enemies Closer, Zak is asked to remove a strange cryptid from Dr. Beeman's lab. In exchange the Secret Scientists will halt their pursuit on him for six months. Unfortunately, the shape-shifting cryptid appears to be immune to Zak's powers. Zak secretly places a neural parasite on Fisk's back to make contact with Argost. He then asks him how to stop it, and Argost helps by explaining that the cryptid has to be in a certain area where it can use only one form. Zak then lures the creature into a pool, and is able to control it, long enough for Fisk (under Argost's control) to seal the pool shut. But then while Zak explains his actions to Doc and the Scientists, Komodo discovers the parasite on Fiskerton's back. Paul Cheechoo assumes that Zak knew about it the whole time. Before Zak could explain everything, Argost's warship shows up, and Zak is forced by Arghost to leave in it, leaving everyone else puzzled and shocked. Argost releases a gas that knocks Zak unconscious. He later wakes up in a Munya cocoon on what Argost calls the most isolated island in the world. After seeing Argost use the smoke mirror to summon Zak Monday, Argost uses the Flute of Gilgamesh to steal Zak Monday's power for himself, thus killing Zak Monday in the process. Zak Saturday uses his power to control Munya to free himself to fight with Argost, who both try to control Munya as a weapon. Unfortunately, Argost gains the upper hand, and is about to finish him when suddenly, Tsul 'Kalu, Fiskerton, Komodo, and Doc arrive in the nick of time to help Zak. Argost and Munya escape to prepare for the possible destruction of the world. Once Argost leaves, Doc says that Fiskerton has explained everything about why he got help from Argost. Fortunately, Doc still trusts and loves Zak, saying that he was only worried about his safety. The episode ends with Doc nicely telling Zak that there is still a lot more explaining to do about why he trusted Argost. Zak responds by saying, "First we need an army of our own."
In War of the Cryptids, he shows mastery of his power, by controlling large amounts of cryptids around the world. He later made a deal with Argost to stop all the fighting. Sadly, after Van Rooks death, he has the "Kur" sucked out of him by Argost who later seemingly is utterly destroyed by fusing Matter and Anti-matter together, making him finally normal, but that was termporay. Zak is officially "dead" for 3 minutes, but ends up okay, thanks to his parents.
In Ben 10: Omniverse in episode T.G.I.S, The Saturdays, Ben Tennyson and Rook Blonko team up to defeat Argost and Dr. Animo

- Though it is possible that he turned twelve in Life in the Underground, sense he was eleven during Kur Rising, and six months later he was twelve, so it is possible that Jay (In the beginning of Kur Part One Where it said twelve years ago) and Doc were simply rounding up to twelve since his birthday was so close. Therefor Zak has only age one year, and will age two years in season three, of course this could be revealed in season 3.
- At the beginning of Kur Rising, a symbol that appears to be the letter "C" with a line connecting to a circle is shown on the Kur stone. The same symbol appears at the end, but this time appearing in Zak's eye. Jay has revealed that that symbol means Kur].
- Zak is a playable character in the Cartoon Network game, TKO along with Munya and Van Rook. Zak's special move is a laser beam that shoots from his head, probably representing Zak's power.
- Ironically, Naga did try to kill Zak in The Atlas Pin and The Kur Guardian, the person/cryptid that she wants in order to create a new era of cryptids.
- In the episode Kur, Zak sees a vision of him controlling the cryptid army to overthrow humanity.
- Despite learning that Zak is Kur, Fiskerton continues to protect Zak, possibly guarding him from his own Kur instincts. But, in Kur, he seems to grunt more often to Zak, probably because of his Lemurian instincts.
- In The Return of Tsul 'Kalu it is revealed that Zak was responsible for the loss of Doc's right eye, though it was unintentional, when he was very young Zak accidentally destroyed a sacred site. Tsul 'Kalu was the site's protector, and went after Zak. The Saturdays escaped on the Airship, but Tsul 'Kalu got on and went after Zak, Doc found him and convinced Tsul 'Kalu that Zak was too young to know what he had done and that being his father Zak's mistake was his responsibility. Doc and Tsul 'Kalu battled on top of the Saturdays HQ during a thunderstorm, 'Kalu used a Claw pendant from one of his prey to electrocute Doc which damaged his eye, gave him his scar, and shocked a large part of his hair white. Doc still managed to defeat Tsul 'Kalu, and in return Tsul 'Kalu gave Doc his claw pendant, which Doc later gave to Zak. To keep Zak from feeling guilty, Doc and Drew told Zak that Doc lost his eye in an accident.
- It appears that Kur can affect Zak's decisions. Examples: In Kur Part 2 Zak believed that the Nagas will attack Hong Kong, but they attacked New York, giving the Nagas a big advantage.
- Although he has aged 2 years (being 12 years old up to Kur Part 1-2, and 13 up to Life in the Underground), not much has changed about his appearance, although he has grown a bit taller.
- As of War of the Cryptids Zak no longer has his Kur powers though it is unknown if this is temporary.
- In Target: Fiskerton it shows how much Zak and Fiskerton "Fisk" Saturday really care about each other.
- In Once More the Nightmare Factory shows how Zak really cares about his cryptid siblings.
- It's safe to say that Zak is rarely allowed to watch TV or use a computer because Doc and Drew hate it whenever he watches Weird World.
- Ironically, even though he IS Kur, he is best friends with a Lemurian, who is called Fiskerton, which his best friend is supposed to protect the world from Kur.
