* The TransformationSequence at the end of the first episode. Body Horror UpToEleven: her very heart and blood vessels turning purple, thorns entangling with those blood vessels, and mechanical parts erupting and forcing themselves into Tachibana's body. The GlowingEyesOfDoom and the SlasherSmile make it all the more '''terrifying'''!
* Tsubasa after her Swan Song. Good Lord...
** It's back with vengeance in ''G'', involving Maria's sister Serena.
* In episode seven, Ryoko brings Hibiki in for a medical checkup after her battle with Chris. She reports to Hibiki that the fusion between the fragment of Gungnir and her body seems to be spreading, but assures her that there should be no negative side-effects whatsoever. This eventually turns out to be BlatantLies, as we are later able to see X-Rays of Hibiki's body on a computer screen in Ryoko's office. What the examination revealed was [[http://i59.photobucket.com/albums/g298/strike_zero/Senki20Zesshou20Symphogear20-200720-20Large2029.jpg this]]. ''GYAAAAAAH.''
** Disturbing as that image is, it still doesn't prove it's negatively affecting her. Though, given that Ryoko's [[spoiler:TheMole, a MadScientist, and a sadist]], she probably is lying.
* Berserk Hibiki from episode 12.
** What's worse, Hibiki has at least ''some'' awareness of what she's doing in Berserk Mode, but she can't control herself. She's shown crying during her fight with Tsubasa, and not BerserkerTears either.
* A very early example: If the Noise so much as ''touch'' you, you disintegrate into ash, and as the main page (correctly) points out, it's slow enough that you can feel it happening.. It's an even more horrifically-specific application of LiterallyShatteredLives.
** The first episode even gives you two close ups. The second is particularly disturbing as it shows a young girl ''screaming and crying'' as she's killed by the Noise.
--> '''Girl''': "I don't want to die! I don't want to die! No!"
* The Nephilim from ''G''. Oh, god, the Nephilim. It's a humanoid creature with a taste for flesh, and is neither human nor Noise. [[spoiler:Its crowning moment is biting and ripping Hibiki's arm off after [[RealityEnsues she tries and fails to make it eat her fist.]]]]
** At the start of the next episode, [[spoiler:Hibiki somehow ''manages to top all that!'' Immediately, she becomes berserk again while growing a new arm, beats down the Nephilim with ease, and rips its heart out!]]
* The ending sequence of season 1 is very chilling as it contains images of bodies that are missing limbs and decaying.(See CreepyDoll on the [[Anime/SenkiZesshouSymphogear main page]])
* Season 3 gives us the Autoscorers, who are straight-up confirmed to be artificially-made, and they move in ways that no human would dare attempt. However, their main perk is their KissOfDeath, in which they reduce their unfortunate victim to a lifeless, [[ColorFailure white corpse]]. We already see a couple instances of this in the first two episodes, but Episode 3 gives us entire groups of people lying dead on the ground (one of the girls who happens upon this scene appropriately screams). On top of that, they can create special types of Noise called Arcanoise that can destroy Symphogears.
** The Autoscorers can also destroy Symphogears directly, and are programmed to enjoy doing so. Furthermore, if Carol doesn't find the user's synch ratio "interesting," she's given them permission to use the Arcanoise to slice those people into tiny little pieces!
* In ''GX'' E6, Tsubasa and Chris activate the IGNITE Module upgrade to their Symphogears. You thought Berserk Hibiki was scary? The enhanced Symphogear tuns into a dagger, stabs them both through the heart and forces both Tsubasa and Chris into "Berserk Mode" artificially, with red glowing eyes, smoky shadows, and lots and lots of blood and screaming. They're both fully aware of what's happening, and yes, they finally realize that the Hibiki they picked on when they met her understands more about pain and suffering than either of them ever could. Why? Because Hibiki went through that, repeatedly, on her own, without monitoring or backup, and came back every time!
** The IGNITE module essentially uses rage and anger to augment the fighting power of the Symphogears. It becomes obvious in their expressions and poses during the IGNITE transformation sequences, when Hibiki strikes poses reminiscent of her berserk forms from the first two seasons, Tsubasa is the model picture for TranquilFury, and Chris appears to be under a barely-controlled trigger happy state.
** Adding further to the scariness of the IGNITE module, it can also ''go wrong'', with Maria descending into true berserk mode when she fails to control the IGNITE module.
** Speaking about IGNITE using rage and anger as a power source. Hibiki, the StepfordSmiler too close to the edge, is the one with the ''least'' anger control issues on the team of Symphogear wielders. This is shown by the fact that not only does she use the IGNITE mode flawlessly on the very first try, while everyone else had serious issues, she leads Tsubasa and Chris into using their versions without difficulty. Think about that for a moment.
* The fact that Phara talks to Tsubasa and Maria [[spoiler: right after she was [[HalfTheManHeUsedToBe cut in half]]]] in Episode 10.
* Hibiki is going to live with the guilt of seeing Carol every time she looks at Elfnein. The others she fought in her time as a Symphogear user either found some respite in their end or joined her cause; Dr. Ver became a hero in his own way, Fine saw sense in her death, and the F.I.S. girls pulled a HeelFaceTurn. Carol, on the other hand, couldn't be saved, no matter how hard Hibiki sung or what kind of songs she sang.
