Just be happy she isn't made of flesh and blood!
- Red Lanterns are In-Verse Nightmare Fuel considering their rather blatant body count and reputation as bloodthirsty maniacs and monsters. They're first shown outright killing Green Lanterns, torturing enemies, and have destroyed countless planets, killing billions, in the name of vengeance against the Guardians for killing off their entire quadrant of space with the Manhunters. They're actually shown blowing up a planet and a Green Lantern dies trying to hold off the explosion until his loved ones can get to safety. Not everyone survived the explosion, setting the Darker and Edgier tone of the series. Worse is their plan was to get to Oa and kill the Guardians and eventually slaughter all 3600 sectors of space under their watch. The number of loss lives would be incalculable.
- Atrocitus himself is pretty much a nightmare strictly because of how he's a deconstruction of the Roaring Rampage of Revenge. He's been driven so insane for revenge after the Guardians' Manhunters destroyed his world he goes about doing the same to many other worlds with a fleet of Planet Destroyer Warheads just to get revenge on the Guardians. He even instigates wars on various worlds like he did with Razer's to create new possible recruits for his Corps and if that doesn't work he'll personally kill the loved ones of those he views as promising recruits.
- In "Reckoning" Atrocitus rips Aya's limbs off and dangles her from her neck in front of the interceptor crew. He then gets ready to chuck her body into the Red Lantern Battery to kill her off. The fact she has realistic veins and arteries dangling out from her torn limbs only makes it worse.
- The Spider Guild's Prison is a particularly nasty Hellhole Prison considering the prisoners of the Spider Guild's prison are forced to relive their worst memories before being eaten by them.
- "Prisoner of Sinestro" plays out as The Thing from Another World in space, and the entire crew is creepy while possessed. Special points go to Razer's borderline sexually harassing Aya, and Hal's Slasher Smile.
- Sinestro's plan for driving the creature out of its host body. He sets the Interceptor to decompress, depriving the ship of oxygen. The crew members who aren't possessed will be able to protect themselves with their rings' force shields. Razer ends up being the one possessed, and he nearly suffocates. We're treated to several seconds of him gasping for breath and even passing out for a few seconds.
- To add a third point to that episode, Sinestro's Breaking Speech to the dying mindjumper, revealing that he broke the seal when he broke out and leaving it to die, his truly creepy exploitation of Loophole Abuse (he didn't kill him, he just didn't save him), and his utterly calm lie to the crew that he must have suffocated, and how convenient it is that he died. He may remain a good guy throughout the entire episode, but it's made very clear that when he becomes a villain, he will be terrifying.
- The Anti-Monitor is pretty terrifying in-verse considering its reputation as a virtually unstoppable being infamous for converting entire galaxies into antimatter to be consumed for its insatiable hunger. Think Galactus as an Omnicidal Maniac up to eleven. The moment it gained sentience it devoured nearly the entire antimatter universe, killing trillions upon trillions of lives, devouring millions of galaxies and planets, eating all of its stars, and leaving only one planet left to exist in the universe that was slowly dying out. If left unstopped, it would have devoured the universe of the main cast as well.
- Aya survived her brush with death by downloading into a disabled Manhunter. While it is good to see her alive, the mangled Manhunter/Aya form she comes back in is quite disturbing. She then shuts down her emotions and absorbs the entire power supply of the Interceptor before using it to kill the Anti-Monitor... then hooks up to his systems and become the new Big Bad.
- It was hard to watch Kilowog, Hal, and Razer nearly kill each other from the effect of the Orange Lanterns.
