Jack is the brother of Rick Marshall and uncle of Will Marshall and Holly Marshall. When Rick, Will, and Holly went missing, Jack began searching for them after six months by taking the same route they took, and eventually falling through the same time doorway. He ended up arriving in the Land of the Lost at the same time Rick returned home by using one of the Pylons. When he catches up with this nephew and niece, he caught on fast to the situation, using his wits to outsmart many things in the Land of the Lost.
In their first meeting, Jack fooled Malak into thinking he was a god. He then used a pain killer to help Malak's tooth ache, later lighting a fire with a match. Malak claimed he could do the same. When Malak was not looking, Jack dipped them in water so they wouldn't work for him. Jack later told him that he had a scepter that can create light which was actually a flash light with weakening batteries. Jack got Malak to stop draining the river which dehydrated the animals and flooded the home of the Sleestak in exchange for the flashlight. Malak agreed, but the battery soon ran out and Malak was overthrown by the Sleestak. Jack also once tricked Torchy to be trapped in a canyon.
Jack also faced several enemies with whom a peaceful settlement or negotiation was inconceivable, truly evil entities such as Medusa, whom he had to trick into turning herself into stone. When the Sleestak gained more intelligence as well as the guidance of a malevolent power in the form of the Sleestak skull. Jack also met Captain Reuben Van de Meer, the captain of the famous ghost ship, the Flying Dutchman.
Jack wasn't above using violence against the Sleestak such as homemade bombs and flare guns. But presumably out of consideration for Enik, he avoided deadly force when possible, using such tactics to scare instead of deliberately take Sleestak lives.
