In 1992, Valiant Comics introduced a revamped Turok, debuting him in Magnus: Robot Fighter #12. With this version, the concept and setting were altered. Turok and Andar were now 18th century Native Americans. The isolated valley became "The Lost Lands" - a land where Demons, Dinosaurs and Aliens flourish and where "Time has no meaning". A cosmic anomaly causes time in The Lost Lands to move in a self-contained loop (which means that while millions of years pass outside of it, inside it, time barely moves at all). "Unity", a line-wide Valiant Comics crossover storyline, altered the concept even further. The crossover's main villain, a psychotic, super-powered being known as Mothergod uses the Lost Land as the base of operations. She outfits Dinosaurs with intelligence-boosting implants, turning them into "bionisaurs".
In the aftermath of the final battle between Mothergod and Valiant Universe heroes, the Lost Lands begin to disappear. Turok and Andar are tossed into a post-apocalyptic future Earth, and a group of bionisaurs make it to Earth along with them. Following this, they become ruthless hunters trying to contend with the demons and aliens that exist in the future world as well as various Lovecraftian abominations and high-tech future warriors. Mothergod seizes power in this future and, with the help of The Campaigner, The Longhunter, Thunder (a biomechanical Tyrannosaur) and Mantid (a 30-foot robot praying mantis), begins to rebuild her empire and attempt to hunt down and kill Turok and Andar.
A new volume of Turok's own comic, titled Turok: Dinosaur Hunter, was launched in 1993. Valiant published a total of 53 issues before Acclaim purchased the company, including Turok: Dinosaur Hunter #0-47, Original Turok: Son of Stone #1 & 2, Turok Dinosaur Hunter Yearbook in 1994, and the two-issue mini-series Turok the Hunted in 1996. Turok: Dinosaur Hunter #1 was the 6th best-selling comic of the month, surpassed only by the first five installments of "Reign of the Supermen!".
