Nightmare Fuel / Batman Beyond
Audience, meet Earthmover. Earthmover, meet screaming audience.
Thought the original animated series was dark? You haven't seen anything yet.

  • Blight nicely sets the Nightmare Fuel tone for the series right from the early going.
  • The final fate of Ian Peek in "Sneak Peek". After abusing the intangibility belt, he winds up becoming intangible without it and unable to be selective about what he's intangible to, causing him to fall from the top story of a huge building through floor after floor while batman's constantly trying to swoop to grab him as Ian's screaming for help. Batman finally manages to grab him and encourages Ian to focus to stay solid, and for a second it looks like it works, until he seems to just lose all spirit and slowly sink into the basement floor, laughing for a moment, then screaming/crying until his voice becomes muffled by the floor and begins his descent into the center of the earth. This guy committed murder, but that is still a horrible way to go.
  • Earthmover. Essentially a motionless, decaying corpse half-melted into the surrounding earth — except for the glowing green eyes. Seriously creepy even for this series, especially since his character model was more detailed than anyone else's.
  • In "Lost Soul," the final fate of Robert Vance. Whether he was the real deal or just a deluded, rogue program that thought he was Robert Vance, and regardless of the horror he was going to subject his grandson to note  (which is Nightmare Fuel in and of itself), seeing (and hearing) the man mentally regress to infancy and cry out for his mother and father as his data is deleted for good is cringe-worthy.
    Robert Vance: "Five hundred megs! A thousand kilobytes! Pi r squared! Two plus two equals four!" (voice then reverts to that of a child, and then becomes baby talk) "Me first! I wanna play! One potato... Two potato... Mama! Papa!... Mama!"
    • There's also the moment when Vance's program manages to get into the Batsuit. He realizes that Terry is nothing more than a hindrance, so he decides to get rid of him... by drowning Terry. The way that Terry fights the suit as it walks into the ocean is incredibly agonizing to watch. Sure, Bruce realizes what's going on and uses the failsafe "get the suit's joints to lock up" thing, but that only happens once Terry is neck-deep in the water already. He's stuck there, trying to stay upright and alive as he gets hit by wave after wave until Bruce finally comes to get him.
    • "Where will I be?" is answered with a deadpan, "Wherever deleted progams go." Robert Vance views his grandson as a program to be erased and replaced with himself.
  • Terry's transformation in "Splicers."
    • Terry arriving back at the Bat Cave with only enough time to toss his mask at Bruce's feet and reveal himself to be almost fully transformed as he says the above-mentioned line before going full bat and attacking Bruce.
    • Particularly chilling how, after injecting Terry with the splicing stuff, the doctor calmly tells him, "You're welcome to your opinions, while you're still human enough to have them."
    • Dr. Cuvier's final transformation. He starts off injecting DNA into himself to become a chimera. Terry then starts pumping random serums into him, causing him to turn into a mass of sinew and bile. See for yourself.
    • The fact that Cuvier's transformation kinda looked like Tetsuo's from AKIRA makes it even creepier.
  • The flashback to Stalker's back surgery in "Bloodsport." It's made very clear that for whatever reason, the surgeons didn't want to put him under when replacing his spinal chord.
    • The Stalker was supposedly killed when he was run over by a train. Why didn't he leap out of the way? He hallucinated and thought it was a panther. In fact, the Panther that mauled him in the first place.
  • The subjugation the kids go through in "Last Resort." Children are brainwashed Big Brother-style, denied food, sleep, or even contact with the outside world until they break.
  • Inque's first serious attempt at killing Batman. She crams herself down his throat! Sure, Bruce and his fire hose come to the rescue, but that's got to be a pretty unsettling way to go...
    • How about what she does to Aaron Herbst, that poor guy who helps her get her humanity back in her second appearance? She gives him half the mutagen treatment, leaving him a wretched half-human, half Blob Monster that ends up in the same facility that was studying Inque...
    • Everything Inque does. The first time she actually attacks Batman, she does so by blackening the entire screen save for the corner where he is. Talk about Nightmare Fuel for claustrophobiac. And then there is multiples instance of her going full Eldritch Abomination.
  • In Return of the Joker, Terry returning to the Batcave to find it vandalized, and Bruce lying on the floor, dosed by Joker venom, barely able to move or speak without succumbing to the venom and nearly laughing himself to death. It had to be a bit of an in-universe example as well, since the scene with the vandalism directly recalls Terry's father's murder.
    • Joker's Moral Event Horizon with what he did to Tim Drake. That scene alone speaks for itself and this actually pushes Batman to try and KILL the Joker.
      • Also another case of an in-universe example when you retroactively revisit first-season episode "Disappearing Inque." Suddenly Bruce's actual display of very real concern when Inque kidnaps and threatens to kill Terry makes a lot more sense, considering what happened to his last protege when that happened... and explains why he was willing to risk himself in a fight instead of coaching Terry through an escape somehow.
    • The feeling was mutual for Terry, when Bruce dons an experimental suit. While us Animated Series fans were cheering that Batman was back, Terry faintly lets out a concerned "No." because he knows that suit is gonna kill Bruce whether he beats Inque or not.
  • The ending of "April Moon", where the unsuspecting gang leader is about to get killed. With a drill that is slowly closing in towards the camera. If you ever had a fear of the dentist, that's bound to set it off.
    • "Killed?" This guy kidnapped the wife of a cyber-doc for free augmentation for his gang, then came back to him for repairs after the poor doctor found out his wife was in on it and was cheating on him with the gang leader. He was Strapped to an Operating Table to be worked on by a trained surgeon who hated his guts and no longer had any reason to fear him or anything to live for besides revenge. IF he died, it probably came as a blessing.
  • In "Spellbound", the massive insect world hallucination along with Spellbinder in general who is a school counsellor who the kids should be able to trust but instead he uses them to steal valuables because of his ego being slighted.
  • In "Mind Games", Tamara, the creepy psychic child who looks eerily similar to Ace from the Justice League series, uses her powers to permanently blind the Invulnerable Man. Watching him go insane from losing his sight is pretty chilling. Especially when she could have just made him unconscious. It's made even more disturbing when it was thought to be payback for his abusive behavior.
  • What about the episode "Rats"? Dana is kidnapped by a delusional stalker with giant rats as pets! At first he seems like a sympathetic character talking about how society rejected him for his looks, but by the end of the episode it's revealed that he's a serial killer that feeds teenagers to his rats! If Batman hadn't showed up Dana would have definitely been killed.
