There are a number of horrifying things that exist in The Marvelous World Of DC universe.
- The reveal that among the numerous alien races of the Marvelous World of DC are the Xenomorphs and Yautja. Yes, those Xenomorphs and Yautja. And apparently the Men in Black have had dealings with them too.
- Galactus consuming Krypton is a massive case of parental worries for Jor-El, who desperately races home to save his son.
- Sabretooth is disturbingly eager to kill Nazis. Granted, he's only killing Nazis, but Finmonster is foreshadowing his eventual Face–Heel Turn.
- The birthing ceremony of Raven. First, a wave of malicious demonic energy is released through the castle, causing Hellboy's demonic horns to briefly start regrowing, and Jason Blood to start reverting to Etrigan. Then the BPRD makes themselves known, and find that every single cultist in the room is a vampire (apart from Rasputin. And Kroenen. And Mordo. Or Blackheart.), and a massive fight breaks out. Thankfully, most of the Church of Blood is a Red Shirt Army.
- Adding to the above, Hellboy has to cross the Godzilla Threshold and go Anung Un Rama mode in order to actually hurt Blackheart. Apart from his horns regrowing, Hellboy also ends up Wreathed in Flames and gaining four red Glowing Eyes of Doom, and he makes disturbingly short work of Blackheart with his sheer power. And afterwards, in his Unstoppable Rage, Hellboy nearly ends up strangling his ally Jason Blood before he snaps out of it. And then there's the reveal of who Hellboy's father is that he got this power from: none other than Trigon himself.
- The Spectre's introduction solidly establishes him as an Ax-Crazy Knight Templar who Does Not Like Magic, and is singly responsible for forcing the Wizarding World to go into hiding. And his initial dialogue with Dr. Fate doesn't help with the way he starts off calm, if vindictively sarcastic, but when he hears his ways being criticized, starts furiously shouting at Fate. One gets the feeling that if he wasn't imprisoned in a glass bowl, he'd kill Kent Nelson on the spot, Helmet of Fate or no.
- Apparently, Stephen Strange's father died from having a hole melted through his chest. And we don't have any clue who did it.
- Mordru creates an Improvised Golem from Strange's apartment wall (which he blew open fighting the Phantom Stranger) and orders it to kill any Muggles it finds.
- Agent D is giving young Clark Kent a lecture about the life-cycle of a Xenomorph (well, the actual name used is Xenophage, but I think we can all guess what he's really talking about), and Clark is appropriately disturbed.
- Agent K's half-hearted attempt at arresting Clark when he tries to leave the Kent farmhouse is pretty jarring because of how Good Is Not Nice K comes across as. He suddenly whips out a lump of green Kryptonite, knocking Clark unconscious, and orders his men to restrain the Kents and escort the unconscious Clark into a car, where they will take him to a maximum-security MIB safehouse. Granted, we learn he was actually running a Batman Gambit to get Johnathan to knock him out, break his Kryptonite, and let Clark escape, but still, pretty callous.
- Loki's Establishing Character Moment. After locating his brother Thor on Themyscira, he travels to Gotham City, entering the apartment of Stanley Ipkiss by teleporting through Stanley's cartoons, and brainwashes him-painfully- before sending him to Themyscira to kill Thor. And after initially presenting himself to Stanley as a friendly person.
- The Mask attacking Themyscira. After Riding the Bomb into Thor's bedroom, he confronts the Asgardian with creepy red eyes, a Slasher Smile, and disturbing giggling. The fact that he never says a word throughout their entire battle makes him even more frightening. At this point, he's more like the Ax-Crazy comics version of the Mask than his more heroic film counterpart.
- Also, the way Thor cures Stanley's brainwashing. He carries him into the sky and summons his Cool Uncle Zeus, and they combine their lightning and conduct it through Stanley's body. Granted, being Made of Iron, Stanley survives electrocution, and the two gods have good intentions in mind, but he still screams in pain while they're doing it.
