|In Mortal Kombat|
|Games||Mortal Kombat X (DLC)|
Jason sports his usual, rugged attire that is consecutive within the Friday the 13th films. Jason's appearance includes his iconic hockey mask, torn-up jacket and the machete that he wields as a weapon. With the exception of Goro and Tremor, Jason is prominently taller than the other Mortal Kombat X characters.
- Mortal Kombat X: Death and revenge make up the very core of Jason Voorhees' being. He died as a young boy. His mother killed out of grief and rage. When she was murdered, Jason returned and avenged her. Many times since, the living have tried to send him back to the realm of the dead. He's been stabbed, drowned, electrocuted, hurled into space. But Jason cannot be killed. Cannot be stopped.
Powers and abilities
Jason is an undead, ruthless killing machine and possesses immense strength. His undead nature renders him completely implacable and nearly unstoppable, being virtually immortal. Even more so, his brute strength allows him to toss his opponents effortlessly and deliver powerful blows with his fists and machete.

- Mortal Kombat X: "Like Scorpion, Jason Voorhees was a revenant: a vengeful spirit returned to life. Hundreds had fallen victim to his bloodlust. Liu Kang, now ruler of the Netherrealm, took notice. An immortal killer like Jason would be useful in his plan for konquest. He drew Jason into the Netherrealm and offered him an endless bounty of slaughter... in return for his allegiance. Jason's simple reply was to destroy Liu Kang."
- Jason is the second slasher film villain guest character to appear in the Mortal Kombat series, the first being Freddy Krueger and the third being Leatherface.
- Jason's announcement teaser trailer was officially released on Friday the 13th (March of 2015), matching the title of his origin franchise.
- Jason's fatality "Sleeping Bag Killer" comes from the movie, Friday the 13th Part VII: The New Blood, in which Jason kills Judy by repeatedly smashing her against a tree while she was in a sleeping bag. In MKX, however, he doesn't put his victim in a sleeping bag.
- The chain around Jason's neck in his Unstoppable Variation, as well as the lightning used to resurrect him, are references to Friday the 13th Part VI: Jason Lives.
- Jason is one of the few characters to have a brutality that derives from his X-Ray, and not only from special moves, throws, or combos. The other characters are Sonya, Erron Black, Jacqui Briggs, the Predator,Tremor, Leatherface, and Triborg.
- He's also one of the only characters who can interrupt his X-Ray to perform a different move, since the characteristic decapitation from his brutality replaces the final hit of his X-Ray. The other characters are Jacqui and the Predator.
- In the Friday the 13th movies, Jason had a misshapen skull, rotting teeth and one of his eyes was lower than the other, but in Mortal Kombat X, every X-Ray shows Jason having a regularly shaped human skull, and a recent hack for the PC version removes Jason's mask and reveals his face, which merely has several scars on an otherwise middle-aged man.
- Jason's default appearance is heavily based off his appearance in Freddy vs. Jason, perfectly replicating his attire from the film. His Player 2 color is based on Roy Burns' appearance in Friday the 13th: A New Beginning, down to the black clothing and blue hockey mask chevrons.
- All fights that pit Jason against the Predator or Alien will activate an odd glitch in which the victim that Jason drags in his intro has the same blood as whoever he's fighting. This is also true for the intro where he removes the combat knife from his neck as the blood around the wound will have the same colour blood as his enemy.
- Jason is the only character in the game to have specific music play during both of his fatalities.
