Goku is one of the most powerful main characters not only in his universe but in all of fiction. As such, fans of Dragon Ball will often speculate on who would win in a fight between him and another powerful opponent. He'll often be pitted against the likes of Superman, Saitama, and Pegasus Seiya. However, every once in a while, someone will suggest an opponent who doesn't really seem like they'd be a match for someone as strong as Goku; this is where Friday the 13th's Jason Vorhees comes into the story.
A fight between Goku and Jason should have no reasonable outcome where Jason emerges the winner. Even with his superhuman strength, Jason armed with conventional weapons should not be able to defeat an opponent who fights opponents with planet-destroying capabilities and higher on a regular basis. However, maybe there is a chance. Maybe Jason and Goku each have qualities that would make this fight less of a blowout. A true assessment of how a confrontation between Goku and Jason would play out will require an analysis of their abilities, weaknesses, and win conditions.
The first thing Dragon Ball fans would likely point to is Goku's durability. He has been virtually bulletproof since the start of the series. More relevant, however, would be the time someone shattered an ax on Goku's scalp, a weapon Jason is more likely to use than any firearm. Goku has gotten exponentially stronger since then, so it stands to reason that whatever conventional weapons Jason has would be ineffectual against him.
However, the effectiveness of weapons against Goku and the Z Fighters has changed throughout Dragon Ball's run. At the 23rd Martial Arts Tournament, Tien gets sliced open by Mercenary Tao's hidden blade; he even has the scar to prove it. In Dragon Ball Super, Goku gets shot by a ray gun, pricked by a needle, and even grazed by a bullet. If anyone wants to take anime filler into account, he's also been hurt by a rock thrown at his head when his guard was down. It seems that as long as Goku doesn't keep his guard up, he can still be hurt by that which wouldn't normally harm him.
Goku's vulnerability, when caught by surprise, could potentially be exploited by Jason. Jason is a master of stealthy kills and sneak attacks. He might be able to sneak up on Goku and deliver a mortal wound unto him.
This would be a time where Jason's being closer to human-level than planet-buster-level works to his advantage. Goku is normally on the lookout for stronger opponents, so he wouldn't think anything of Jason's relatively low power, and leave himself unprotected. He might not even notice if Jason's in the vicinity. As long as Goku doesn't sense Jason coming for him, he remains at risk.
Another way Jason could catch Goku off guard is with his immortality. As an undead revenant, Jason cannot be taken out by conventional means. He's even been shown to survive atmospheric re-entry and point-blank nuclear explosions. Assuming that Jason goes through a cycle of getting the drop on Goku, stabbing him, getting "killed" by him, coming back, and repeating the process, the accumulated damage he inflicts could take its toll on Goku over time.
Even if Goku can deter Jason, there's no telling what he could do to his friends. Goku has some very mortal people in his life that Jason may go through to get to him, including Bulma, Oolong, Mr. Satan, and Yamcha. This kind of indirect attack would definitely compromise Goku mentally and emotionally, leaving him open for even more surprise attacks.
While Goku can't necessarily kill Jason, he does have another way of stopping immortal beings-- containment. After trying and failing to stop the invincible Zamasu, Goku learns the Evil Containment Wave so that he can seal the Kai forever. If Goku gets the chance against Jason, he can seal him away just like he would Zamasu, and that would be the end of his troubles.
Jason would never be a match for Earth's greatest warrior, but he just might be able to give him some issues. He should at least be able to get one good sneak attack in on Goku; whether it's fatal or not remains to be said. Even if Goku thinks he's beaten Jason, the undead killer can always revive himself and come back to haunt the Saiyan and his friends. At this point, however, Goku should be able to deal with Jason once and for all with the Evil Containment Wave. Fans of either Dragon Ball or Friday the 13th should look forward to Jason Takes West City if there ever is such a thing.
