''As a Moments subpage, all spoilers are unmarked. You have been warned.''

While a crossover between these franchises is bound to have its awesome moments, it's just as bound to have its horrifying ones.
----

* The flashback sequence at the beginning of the film. That along with Freddy's narrating shows every terrible thing Freddy's ever done to the kids of Springwood. And he's ''proud of it''.
** And Freddy screaming "I CAN'T COME BACK IF NOBODY REMEMBERS ME! I CAN'T COME BACK IF NOBODY'S ''AFRAID!"''
* Lori's last nightmare after she fails to bring Freddy into the real world. Her terrified scream and yelling "Wake me up!" as she sees her father carrying a blade towards his bedroom. Upon seeing her mother's bloody body, Lori assumes her father is going to murder her, only to realize Freddy is the real murderer, who gleefully repeats his crime in front of a screaming Lori. It turns out her father performed a MercyKill on her mother to save her from Freddy. Unable to escape, Lori is subjected to Freddy giving her cuts on her breasts as he grins sadistically and almost perversely. Then Freddy slides his finger blade up her thighs while she is unable to get up, and pulling her skirt up, revealing her bare legs as she whimpers and writhes on the floor as he tells her "the first time tends to get a little.. messy". It's not difficult to see why some fans believe he would have raped her.
* Mark's nightmare is probably the scariest scene in the film. He quickly realizes exactly what's going to happen and that ''there is absolutely nothing he can do about it.''
--> "Somebody please wake me up! ''Please!''"
* Freddy Krueger's past is laid out in a prologue that features an [[NothingIsScarier offscreen]] murder of a little girl -- who's later seen in a dream sequence ''with [[EyeScream her eyes cut out]]''. Say what you want about Freddy's VillainDecay, but he got his reputation '''for a reason'''.
** Basically, that was the scene that instantly reversed two-decades of VillainDecay for Freddy: even with the stupid gags, even with the lame jokes, he kills children ''for fun.''
** There's also the way he slowly ''licks'' her photo before pasting it in a book filled with newspaper articles about missing kids in Springwood and photos of all the kids he's killed. It's quietly terrifying and leaves you feeling [[NauseaFuel fouled]] just by seeing it.
** And her reappearance in Lori's dream adds credence to the fan theory that ''every child'' that has ever appeared in a Freddy-created dream, from the jump-rope kids to the little girl on the tricycle, was an individual victim of Krueger's child-murder spree in life. They're not just hollow imagery he throws in for ambiance, like the boiler rooms or slash-marks: he's evoking their images (or worse yet, ''compelling their trapped souls'') to play a part in setting up more victims.
* Freddy's torment of a young Jason after their Dream World fight is horrific -- especially considering Jason is a little boy and Freddy is a ''[[NightmareFuel child murderer]]''.
** If that's not bad enough, in one of the unused scripts for the film Freddy was to be a ''counselor'' at Camp Crystal Lake and '''molest him.'''
* The opening scene of Jason's nightmare - assuming it's accurate to his history and not Freddy making it seem even worse - makes his origin-story even crueler than it had been, revealing that he hadn't just been out swimming when he drowned. A pack of bullying young campers ''chased him into the lake'', taunting and throwing things at him, then stood jeering on the shore to ''watch him die''. And presumably never owned up to it, given Pamela Voorhees' sincere belief that it was ''solely'' the counselors' fault.
* Kia lampshades the nightmare of having to deal with both Freddy (who attacks in dreams) and Jason (who attacks in reality) with one line: "We're not safe, awake or asleep!" Lori downplays it a bit by reminding her it's their dreams that's killing them, not sleeping.
* Jason's dream at the beginning of the movie. It's a typical scenario that ends with Jason killing a lusty half-naked camp counselor in the woods at night. Then he starts to hear his mother's voice calling him. Then the girl he just killed comes back to life, morphing into his other victims, all of them saying they deserved to be punished. After this, Pamela Voorhees appears. It's a very eerie look into Jason's psyche, even if it does turn out to be part of Freddy's plan.
--> '''Pamela''': Jason. My special, ''special'' boy. Do you know what your gift is? No matter what they do to you, you cannot die. You can never die...
** The first part of the dream is pretty darn creepy too. The doomed woman's terror as she scrambles through the mist-shrouded woods is palpable, and to make matters worse, [[NothingIsScarier we never see Jason clearly until he actually kills her, but both we and she know that he's out there and coming for her...]]
* There's something mildly disturbing in seeing Jason come back to life. You get a close up of his open chest cavity, with discolored bones and decaying organs that have ''vines'' growing through them. And that excuse for a heart starts pumping.
* The scene where Freddy deliberately drowns kid Jason and the real world scenes of adult Jason suffering for them. It's one of the few times, [[SympathyForTheDevil both the characters and to an extent the audience are worried about what's happening to Jason.]]
** That and when Jason is woken up, his kid self vanishes, leaving Freddy so pissed he looks up at Lori before lunging out of the water as everything turns red, [[OneWingedAngel now looking more like a burnt demon version of himself]]. Freddy's made it perfectly clear that now, ''he's not gonna hold back with her''.
* Jason killing Trey. [[TheresNoKillLikeOverkill He stabs him numerous times with the machete, then pulls both ends of the mattress he's lying on together,]] [[FoldSpindleMutilation viciously contorting his butchered body while he's still barely alive.]] It's pretty horrible to look at, and rightfully fucks up Gibb when she sees it.
* Blake wakes up after nearly being killed by Freddy in a dream. While catching his breath, he realizes his dad is sitting right next to him, staring out at nothing. He touches his arm to see what's wrong, and his dad's head rolls off his shoulders and lands in his hands. Horrified, he then turns around to see Jason standing right there on his porch. [[CrossesTheLineTwice There's a very raw cut away as Blake screams and actually tries to shield himself with his father's severed head]] just as Jason goes all MacheteMayhem on him.
* Freddy lures a drunken, sleepy Gibb away from the rave by taking on the form of her dead boyfriend. This being Freddy, he doesn't make him at all appealing and in fact just looks like a living, clothed version of the broken, mutilated corpse Jason left behind. It's creepy watching him stagger off into the cornfield and threatening her if she doesn't follow.
** In a deleted scene, Gibb encounters her boyfriend again, and this time she can see the results of Jason's attack on him firsthand: his body looks like it's made out of rubber, the way his spine had been completely broken when Jason stabbed him multiple times before he snapped him in half. And when she asks what happened to him, he responds angrily, "What the hell do you think is wrong?! I've got a fucking machete shoved up my ass!"
* Gibb is freakishly unlucky. First she's traumatized by the sight of her brutally murdered boyfriend (who was already verbally abusive), then she's lured into a dream by Freddy who slowly hunts and terrorizes her. Immediately after passing out in a cornfield, a man starts molesting her unconscious body. Before Freddy can kill her and the man can rape her, though, Jason impales both her and the rapist. Poor girl could not catch a break.
** Actually, Jason killing her WAS pretty lucky for her [[MercyKill given the alternatives.]]
** Freddy's livid reaction to Jason killing Gibb right as he was about to do it himself.
--> '''Freddy''': [[BigNo NO!]] She's mine! Mine! [[FreakOut MINE!]]
* Just imagine, you're at a rave, probably a little drunk or stoned (and definitely not taking the recent murders seriously)... then Jason comes walking out of the corn field, [[ManOnFire engulfed in flames]] (as seen above) and starts slaughtering everyone in sight as the fire starts to spread. Hope you have the car keys, otherwise you're in for a very ill-fated run for your life. Even worse is no matter what they tried to do, [[NoSell it would do zilch to stop him.]]
** The first two deaths he commits at the rave deserve special mention: whereas the first stoner tries to play tough guy and kick Jason out, he just twists his head around as quickly as turning a doorknob, killing him instantly. Then after Shack throws everclear on him and sets him ablaze hoping it will kill him, he begins to pursue him and ultimately kills him via a flaming machete through the heart. ''Yikes.''
* The part in their last fight where Freddy [[EyeScream stabs Jason in the eyes with his finger blades, and you see Jason convulse and shake as the blood jets from his eyes.]] It makes it clear that while these are virtually immortal monsters, [[AFateWorseThanDeath they can and have endured tremendous agony over the years and felt every bit of it.]] Ouch.
* [[{{Squick}} Let's not forget the scene where Kia is forced to give mouth to mouth to an unconscious Jason Voorhees, as he's drowning in a dream and coughing up liquid.]]
* How about the theatrical ending, where once again it is blatantly illustrated that, no matter how hard you try to kill them, Freddy and Jason will simply never die.
* The parents of Springwood have once again gone to disturbing extremes to protect their children from Freddy Krueger. Censoring any mention of Freddy's existence now that they understand simply knowing of him is enough for Freddy to get their kids? Understandable. Sequestering any and every kid who knows the slightest bit about Freddy in Westin Hills and keeping them doped up on Hypnocil, even to the point of putting them in irreversible comas? Horrifying. It gets worse when considering some, such as Lori's father, have gone as far as {{Gaslighting}} their kids to protect them at the cost of questioning their sanity.
** Their efforts turned out to be for naught, as even if Freddy didn't kill anyone for four years it meant he needed to get creative to get the kids talking about him. Freddy unleashed a killer who could get to the kids in the waking world regardless if anyone knew who Jason Voorhees was, and there was nothing the adults of Springwood could do to stop him.
** Even with Jason killing Trey, that isn't what got the seed of Freddy planted in the minds of Lori and her friends. It was an idiot cop who couldn't help but comment on the murder taking place at 1428 Elm Street ''within earshot of Lori''. And the other officers refusing to explain only got Lori curious as she wanted to know who this Freddy person was they suspected killed Trey. The adults of Springwood are officially some of the most useless, destructive adults in horror fiction and their kids keep paying for it.
