- Harm. In a series that was mostly lighthearted, just about everything about teenaged sociopath Harm was scary, especially his origin - He murdered his adopted sister - who later became Secret - in order to gain demonic powers.
- The Thugee arc, in which a Hindu death cult brainwashes children via a children's television show, is a mostly ridiculous story that has a horrifying denouement where Traya falls under the cult's spell and pushes her own mother out of a window.
- In "Liberty Throughout the Land", one of Traya's classmates loses her parents in a terrorist attack in Bialya, and when they find out that Traya herself is from Bialya, they gang up on her and attack her.
- Secret, while often The Cutie, has a terrifying dark side. It turns out she's a Psychopomp that ushers souls onward by devouring them. While this would normally be only a bit unsettling, she's shown to be fully capable of doing the same to living people. This is how Agua Sin Gaaz meets his end, and the other characters are visibly disturbed by her casual description of what's happening to him inside of her. And worse, when she's corrupted by Darkseid, she ends up eating the entire DEO and Stephanie Brown, and tells Robin that she plans on devouring literally everyone on Earth. Thankfully those victims are released when she's Brought Down to Normal, but one shudders to think of what would have happened if Robin hadn't been able to talk her down.
- Three minors, aged 13, 15, and 16, are subjected to what is essentially torture via DNA harvestation.
- The Joker (who else) gassing the firefighters through the giant plants, or when he takes an interest in Robin while carrying an absurdly huge knife.
- An entire episode of it. And it keeps. Getting. Worse.
- Imagine if the Kobiyashi Maru was happening, except you didn't know it was a simulation.
- Miss Martian's Mind Rape, tellingly and lovingly showed where the Kroloteans twitch and drool as they were being mentally tortured.
- She does this to Aqualad as well, not knowing he's under cover. She could fry an innocent bystander's mind simply because she was angry and not paying attention.
- The Kroloteans get another during the raid on their escape vessel. Superman uses his heat vision to cut one of their spider-mechs in half...and the Krolotean pilot emerges, screaming in pain and covered in burns. An awful aversion of Convection Schmonvection.
- The Scarab can take control of Jaime's armor when it feels the need. Not only is Jaime a prisoner in his own body, but the Scarab is a Sociopathic Hero with no regard for human life whatsoever.
Before the Dawn
- Black Beetle shows how much worse the Scarab could be if it was working properly. Black Beetle isn't uncaring — he's outright sadistic.
- Also, we get a flashback on how Jaime first got the scarab. Despite us knowing it's just Power Armor, the scene just screams of Body Horror.
- Virgil describing what happened to the kids on the Reach's ship. And then we learn that he's not a runaway, meaning many of those kids still have parents who are wondering where they are.Virgil: I don't know why they chose me, but I know that they wanted to break me.
Black Canary: Why do you say that?
Virgil: The tests. They started out small, little static shocks, but they kept upping the juice, till it felt like I was being... eaten by lightning. Still, I was one of the lucky ones. The alien creepazoids didn't seem to like the results that they got from some of the other kids. Kids I never saw again.
- It had been revealed that, since "The Fix", The Scarab had taken over control of Jaime's body because the Green Beetle had rebooted it. If that wasn't horrifying enough, Jaime had been trapped inside his own mind, unable to control his own body for months (April 9th - June 14th) before finally being freed. He was forced to watch the Reach pretend to be him, even interacting with his own family and hurting his teammates. It's amazing that Jaime doesn't show any signs of induced trauma, on the surface at least.
- Wally's death. Not only is he getting hit with huge amounts of energy and visibly in pain from it, but imagine what it must be like to look at your own hand and realize that you can see right through it.
- This was one big reference to Crisis on Infinite Earths where the death is even more disturbing.
- Where to even begin? It opens with a 14 year-old girl with heart disease being kidnapped from the hospital by metahuman traffickers, subjected to experiments shown to be possibly fatal, while she is screaming for help. She survives but instead turns into a monster, that is then sent to fight for Apokolips in an invasion on Rann and forced to fight against the Justice League. All while she is terrified and disoriented and unable to control her own body. And when Black Lighting tries to zap the new threat, her heart gives up, killing her.
- Not only that but Jefferson only tried to knock the creature out, he is terrified when he realizes he might have killed the creature and then he is hit with the reveal it was really a human child.
- When the girl is forced to jump out of the plane, her landing splashes lava everywhere. A Rannian soldier is hit by it and basically vaporized in an instant in a gruesome way.
- The Meta Human Trafficking ring in general. Teenagers and children are being kidnapped, forcefully given powers if they even survive the process, and used essentially as cannon fodder.
- And as we find out later on even the royal family of Markovia aren't safe, as Princess Tara suddenly disappeared and hasn't been seen in two years.
- Plasmus straight-up melts a girl's face off. Thankfully, this particular girl (Halo) is a metahuman with the ability to revive from death and heal completely, but that doesn't change how gruesome it is.
- When we first met Zatara, he looked like a standard middle-aged guy with hair that appears to be just starting to gray. Now, seven years later his hair has gone white. Is it possible that being Fate also ages him prematurely? How many more yearly visits will Zatanna have with her father?
- Halo's Resurrective Immortality has evidently given the writers free license to kill her as much as they want. Here she gets her neck snapped a full 180, which snaps back into place when her powers kick in.
- Kalibak launching captive Metahumans at the Starro-controlled enemy fleet as suicide bombs.
- Cassandra reads Olympia's writings about Vandal Savage's philosophies: Death is waste. It's a waste to kill someone who may serve a greater purpose. So Vandal turns around and... kills Olympia, his own daughter. Because she could thwart his purposes through her senility.
- Orm attempts to kill the Justice League's families, including their young children. While he's stopped by Lady Shiva, she does confirm that this is the Light's "nuclear option" if they are desperate enough.
- Shiva's appearance is enough to induce dread in anyone who's familiar with what she is capable of. The fact that she's able to kill Orm with ease is even more frightening.
- This entire scene shows just how terrifying and overreaching the Light really is. The image of Orm's body and head dropping to the floor shifts back and forth with images and sound echoes of The Team/League's families having fun with each other, ending with Shiva, Orm and his equipment disappearing without a trace. The Light won't kill them because they believe the League won't show any mercy to them afterwards, but the simple fact that they do know about the heroes' social lives and practically have them in their hands is Adult Fear at it's finest.
- One of the participants of the playdate is Mera and her son. Orm hates his brother so much that he's perfectly fine killing his nephew!
- Halo dies, again. This time she takes Lobo's flail through the torso. Dr. Jace doesn't take it well, and while the others are aware it's temporary, there's still a moment of concern.
- The newest member of the Light is revealed: Granny Goodness, literally a goddess of child abuse.
- Not only that but remember those VR goggles? "Goode" as Gretchen Goode a.k.a. Granny Goodness. Can you say uh-oh?
- Also when the Light discuss the Outsiders Queen Bee doesn't refer to Nightwing. No she says Grayson. The Light know who Nightwing Is!
- Victor Stone's body◊ (Warning:VERY graphic) after a lab explosion. The left side of his body is a wreck. The front of his torso is completely blown away, showing his heart. His left arm looks like it went through a meat grinder. An eye is missing and you can see parts of his brain. It's so bad that another scientist rather bluntly points out he's a goner and they need to let Silas say his goodbyes instead of wasting what little time he has left. This isn't depicted as the scientists being callous, anyone would come to the same conclusion with just a single glance.
- The Doom Patrol GO! trip is as dark and messed up as it is hilarious. Gar is stuck in a VR headset watching a bunch of his friends die and being reminded that his mom died.
- Klarion has been activating the meta-gene in kids via painful-looking magic, branding their souls to control them, and then using them to construct a homunculus flesh monster, inside of which they are all conscious and in pain.
- The tie-in comics gave us the Purist...a radical cult that work for Ocean Master. Basically they're against any human/sea-life hybrids...and wish to kill them all. Basically, they're the Atlantean Nazis. They even brand innocent Atlanteans like Topo!
