- Wall-scaling and jumping banelings. They may seem a lot of fun for a player to use, but imagine it from the view of a Dominion marine.
- Kerrigan herself; you can already see in the cinematic what she is capable of, but if you think about it, she is a walking, living Mook Horror Show. Just try to imagine yourself as a soldier of the Dominion. Then, she arrives. She is known as one of the most murderous beings in the Sector. She can blow up tanks with her mind. She can easily tear an army apart entirely on her own, summon banelings right under your feets, bring an entire army of ancient, over-powerful zerg around her or even generate a friggin' Leviathan. Heck, she can even generate her own version of a nuke, and it won't hurt her or her own minions, so she won't hesitate to use it at point blank. If you somehow are lucky enough to hurt her seriously thanks to numbers or big guns, she will just retreat or bury herself underground, heal ridiculously fast and then get out again. And if she is here, the Swarm is most likely to be around as well...
- Arcturus Mengsk seems to have stepped into full on nightmare fuel mode. He bombs civilians, blows up his own prison ship and the men on it... oh and he is working with Narud to create hybrids! At least Wings Of Liberty was ambiguous about the whole thing..
- Much of that may be a direct result of Mengsk's Villainous Breakdown, which was triggered by Raynor's discrediting gambit. He just doesn't bother concealing his villainous nature anymore, and lots of people ended up killed as a result.
- Heart of the Swarm gives us a good look at just how grotesque and sinister the Zerg can be. From weaponized parasites the size of a mans torso, to subterranean tentacles that eat their prey, the Zerg have taken every disquieting feature of body horror, refined it, and honed into something deadly.
- This one's more due to better computing power and graphic cards. The zerg had always been this scary.
- Abathur is affable to Kerrigan, and does not act out of malice or sadism, but he is utterly nonchalant about stripping someone of their humanity. This is a being that not only views people as mere objects, but also has the power to enact that perspective.Kerrigan: What is that sound!?Abathur: Failed experiments. Reverting to biomass. Slow process.Kerrigan: At least put them out of their misery first!Abathur: Wasted effort. Creatures will die soon. Pain irrelevant.
- Kerrigan basically making the Protoss live a Alien remake using Lessara as the host.
- Infested Stukov has glowing eyes and is missing a huge chunk of his face. He doesn't even seem to notice.
- Narud, full stop. Kerrigan's fight with him involves him hiding in the shadow, gloating about how Amon is back already. When he finally reveals himself, he shapeshifts into Raynor, then into human Sarah to play with her emotions. And when she finally slays him, he keeps gloating, while going from Red Eyes, Take Warning to Black Eyes of Evil, using his Evil Sounds Deep voice while still in Kerrigan's form. And in the end, we never really see his true form.
- We do in the later game. It's Xel-naga, and its true form is... unsettling.
- Overlapping with Nausea Fuel, the Swarm Host has been reported to be triggering trypophobia in some players, to the point during development there were calls for the unit model to be changed because people found it unsettling.Explanation .
