* The way that this version of Doomsday is created is rather terrifying. Not to mention they describe him as being more muscled than Bane, Mammoth or Blockbuster.
* Despite the ForgoneConclusion, Supergirl is rather scary as a fury. Brutal, fast, and relentless. And given that she's a full blood kryptonian, she's able to lay Conner flat during their fight.
* Ghosts is a halloween episode, but by far the scariest part of the episode is when [[spoiler: Jason Todd]] takes Nightwing prisoner, and acts all unhinged putting him through a JokerJury.
* The Watchtower attack. The Parademons and Suicide Jockeys, with both the element of surprise and their first encounter actually manage to give 18 different heroes a hard time including Dr. Fate and a GreenLantern, who both have notorious StoryBreakerPower.
** The Vacuum of space is really creepy in how it nearly killed several heroes.
* Cyborg's first appearances are rather unnerving with him being almost like TheJuggernaut hunting down Raven and taking down Beast Boy.
* The BadFuture gives us two bad guys that are really scary.
** The Supermartian: the future son of Conner and M'gann, who effortlessly takes out over half of the team from the future.
** The paratroll. The biggest and meanest of all the genomorphs of the future, and an EliteMook without mercy.
* The NoHoldsBarredBeatdown that Doomsday gives [[spoiler: Superboy and Superman]]. You actually see very little of it, but it's clear from it that very little actually slowed down the beast.
* Darkseid's surprise killing of [[spoiler: Vandal Savage]]. And just like that, the former menace who was a cornerstone of The Light was eliminated with hardly a second thought.
* Klarion's EvilPlan for defeating Dr. Fate. Not only did he have some rather forward thinking, but his evil laugh to set up for the act is rather unnerving.
* Whatever Darkseid did to Kaliback in this universe. It's so awful that nobody on apokalips wants to talk about what happened to him.
