List of The Secret Saturdays episodes

The cover of the second volume of The Secret Saturdays.

The Secret Saturdays is an animated television series that aired on Cartoon Network in most countries and on Teletoon in Canada. The episodes are directed by Scott Jeralds and produced by PorchLight Entertainment. The series debuted on Cartoon Network on October 3, 2008.

The series concentrates on the adventures of the Saturdays, a family of cryptozoologists who work to keep the truth about cryptids from getting out to protect the human race and the creatures themselves. The Saturdays travel the Earth searching for cryptids to study and battling twisted villains like the megalomaniac V.V. Argost. The series is influenced by the style of 1960s-era Hanna-Barbera action series (such as Jonny Quest) and is combined with creator Jay Stephens's own personal interest in cryptozoology.

The first season has 26 episodes and is focused primarily on the Saturdays' search for an ancient Sumerian cryptid called Kur, who has the power to control an army of cryptids. At the end of the season finale, it was revealed that Kur was none other than Zak Saturday, a fact of which not even Zak was aware. On November 7, 2009, a second season containing 10 episodes aired to follow up on the cliffhanger ending. It featured a self-contained story arc focused on Zak and his family dealing with the revelation of Zak being Kur and the consequences of that knowledge. The series ended on January 30, 2010. Contrary to what many people believe, there are only two seasons.

When Zak declines they decide to take him by force. Once the Saturdays get on the airship Zak tells his parents that he wants to help a cryptid because he "wants to do some good" and they go to Istanbul to extract the Lake Van Monster. But the operation hits a snag when Epsilon and Francis show up again. Drew and Doc want Zak to run, but he is determined to help the cryptid, saying that is what they do and that he needs to help something instead of running. Epsilon's "people" have a satellite with the Naga's Kur detecting relic in it, helping them find Zak wherever they go. Doc uses the Griffin to go up into space. After find out that Epsilon's people have a giant space station floating in space, Doc locates the Naga's Kur detecting relic and destroys it. Francis finds Zak trying to help the cryptid and says he is "painfully predictable". He then reveals that he is not Epsilon's son, but they are both clones of their people's best agent from one hundred years ago. Francis lets Zak escape and Zak sets the Lake Van Monster free.

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. Zak's crush for Wadi and hers for him are made more open in this episode. Zak later encounters Argost in a clock tower, who hints at Kur's ability to control an entire army of cryptids from long distances. Zak, Wadi and Ulraj pursue the cryptids underground. Eventually, they fall into a pit that starts to fill with dirt. As they were being buried alive, Zak remembered Argost's words and managed to summon one of the cryptids to save them. The three soon learn that the cryptids were actually making a survival colony to save themselves from Kur. Realizing this, Zak assures the cryptids that he has no intention to harm them or anyone and ultimately earns their trust. 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. Absents: Doyle Blackwell, Zon

Meanwhile, Doyle and Van Rook have met up with Drew and the Tibetan monks and made their way to the lair of the Yeti: the beast that attacked the Blackwell camp years ago and separated the family. Argost unveils his plan to bring Zak Monday into their universe and use the Flute of Gilgamesh to siphon his powers, killing him, as well as revealing himself to be a yeti as Doyle and Drew discover the mold used to make his mask. Zak takes control of Munya using his powers to defend himself from Argost, but is rescued by Doc, Fiskerton, Komodo, and Tsul 'Kalu as Argost flees to raise his cryptid army.

Argost starts his cryptid invasion of the Earth, leading an assault on Washington D.C. After the Saturdays arrive, a fight ensues. Zak goes to confront Argost where he tells him that he too has raised a cryptid army of his own with Wadi, Ulraj, Tsul 'Kalu and many more serving as de facto generals. The Secret Scientists then show up armed with an audio recording of the Flute of Gilgamesh which they use to hurt Argost and Zak. However Miranda Grey, not wanting to kill Zak, destroys the controls to Beeman's ship and Argost escapes with the flute recording. Having retreated to Weird World, he is confronted by the Nagas who pledge their allegiance to Argost. Argost then, on the Naga's advice, orders his army to begin killing the humans. The Saturdays once again invade Weird World where they begin fighting the Nagas. In the process, Van Rook is killed as he sacrifices himself to stop Rani Nagi from killing Drew. Zak, realizing his family may also soon die, agrees to Argost's terms. Argost then surrounds himself with sound-proof glass and uses the flute recording to steal Zak's powers, killing him. However, the interaction of Zak Saturday and Monday's powers kills Argost and deprives Zak of most of his powers. Subsequently, Zak is revived and the Saturdays pay their respects at Van Rook's grave. A news anchorman reports on the incident, saying global climate change is likely to blame and asks if the cryptids left either because they chose to or if the planet owes a debt to a group of unsung heroes.
