Solomon "Doc" Saturday is the father of Zak Saturday and husband to Drew Saturday, along with the adoptive father of Zon, Fiskerton and Komodo Saturday. He lost sight in one eye while protecting Zak from a Cryptid. He was very surprised when he found out that Zak was Kur and was against the Secret Scientists cryogenic-ray freezing his son.
On multiple occasions he has been known to take quick action in protecting his family from threats and other known or unknown enemies.
He can be seen as harsh, strict over bearing and brash towards Zak, however this is most likely because he is worried about his son and the dangers in the line of work he is in. He is very much a loving man and shows his affection more with actions than words.
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.
Doc is of African American heritage, with dark skin, black hair (with a streak of white going down the middle), and one dark brown eye, while the other is a sightless blue color due to him being blind in that eye. Doc has a black jump suit with a orange vest over it, a yellow belt and two yellow gloves, one of which being Doc's Battle Glove, with two big boots.
- According to Doc in Curse of the Stolen Tiger, he met Drew while rock climbing.
- It is known that Zak is the cause of the scar over his eye and the white in his hair.
