"Jason X" (2001) takes place in the future, when Jason has again been inexplicably resurrected. A scientist, Rowan LaFontaine (Lexa Doig), decides that cryonic suspension is the only method of stopping him, but Jason breaks free and kills the army personnel guarding him before he can be again imprisoned. Rowan manages to lure Jason into the cryo‑chamber, but he ruptures the tank and freezes both himself and Rowan. Over 400 years later, a team of students studying Earth discover Jason's body and take it into space. Upon being thawed by the team, he proceeds to murder everyone aboard the spacecraft. He is seemingly killed, but is then resurrected via nanotechnology as a cyborg version of himself. Finally, he is ejected into space and incinerated by Earth Two's atmosphere, his mask falling to the bottom of a lake. The next "Friday the 13th" film, "Freddy vs. Jason" (2003), was a crossover with "A Nightmare on Elm Street". Set in the contemporary period, Freddy Krueger (Robert Englund) resurrects Jason (Ken Kirzinger) and sends him to Springwood hoping that he will create enough fear among the residents that Freddy will be strong enough to invade their dreams. Jason accomplishes this but refuses to stop killing. A battle ensues both in the dream-world and at Crystal Lake. The outcome is left ambiguous, as Jason surfaces from the lake holding Freddy's severed head, which winks and laughs.
