Although the Friday the 13th franchise is currently tangled in endless legal battles, there’s still plenty of lore out there to dig through. In fact, various books and comics were produced that took elements from the franchise and expanded on them in ways that the films never could. For example, in the novel Jason X: To the Third Power, one of several books to take place after the events of Jason X, the titular Jason Voorhees actually has a son.
This is a pretty massive revelation, especially since Jason X isn’t always the most well-received film in the franchise. But the supplementary material which was produced after the film’s release actually builds upon the story in a variety of interesting ways. One such way being the aforementioned son of Jason Voorhees. Of course, it’s worth noting that Jason didn’t conceive his son by natural means. Instead, his child was born as the result of a genetic experiment (further tackling the sci-fi themes introduced in Jason X.)
While Professor Claude Bardox was working on one of the two moons belonging to Earth II, he ran a genetic experiment on fellow geneticist Sarah Jefferson. It was during this experiment that she was impregnated with Jason’s genetic material, and eventually gave birth to a boy named Free Jefferson. Interestingly, Free Jefferson is unaware for most of the book that Jason Voorhees is actually his father. It becomes much more bizarre as a clone of Jason Voorhees goes on a rampage in a space prison. Eventually, as a cybertechnician, Free Jefferson is able to create a second clone of Jason to fight the first. The plan goes a little too well, as the second clone wins and absorbs the first.
Finally, Free Jefferson is forced to launch this superpowered Jason clone into space after it kills his love interest. At this point, Free Jefferson is left alone on the moon waiting for rescue. It’s unclear if rescue ever comes, and his only company is an AI that runs the facility he’s stuck at.
Obviously there’s a lot going on here, as these Jason X books were chockfull of lore and bizarre additions to the franchise. But the concept of Jason Voorhees having a son is an interesting one, and introduces all kinds of possibilities for future storytelling. It’s almost a shame that the storyline for Jason X was abandoned, as there’s obviously so many directions that the series could have gone. Perhaps the story will be picked up again someday – and we’ll finally learn what became of Free Jefferson, the only son of Jason Voorhees.
