Mobile Fighter G Gundam is not short of this, either! Just think of the DG cells and the Devil Gundam. The Gundam Fight itself is one that comes even before DG cells; while the Neo colony nations fight each other using Mobile Fighters for the control of Earth, the Earth has to suffer in silence the property damage and the loss of lives. The message implying the upcoming 14th Gundam Fight at the end foreshadows more catastrophes to come right after the destruction of Devil Gundam.
The "Gundam rapeface◊". Seriously, take a good, hard look at the classic Gundam faceplate. Pitiless, merciless, glowing eyes, that V-fin making it look angry... seeing that staring you down in the middle of a fight would not be pleasant, and has utterly terrified more than one enemy pilot in the series.
Just think of the colony drops - utterly evil and terrifying. Imagine having one colony flattening you right from above your head.
The Mobile Suits in general, all of them are powered by nuclear reactors. It's never stated explicitly where the reactors are but they're pretty damn close to the cockpit where the pilot sits. Any pilot who operates a Mobile Suit either in combat or for general construction work far away from the conflict has to deal with the knowledge that they're sitting next to something that has the potential to go critical if damaged and kill not only them but potentially everyone in the surrounding area. Think about that the next time you see a Zaku going up in a cloud of pink smoke.
By extension, all weapons in the franchise, including warships and even the heroic Gundams themselves, are Nightmare Fuel. One professor even states to Alfred in War In The Pocket that they are Necessarily Evil, and are never meant to bring people happiness. Mobile Suit Gundam MS Igloo even shows us in one episode what it feels like to die at the hands of the White Devil and by extension how terrified Zeon soldiers are when hearing this infamous name.
No matter what the intention Tomino might have, the monotone "La" during Lalah Sune's attack on the Federation fleet in Solomon is absolutely terrifying, echoing an unspeakable horror Zeon's Newtype soldiers unleash. If one doesn't feel it, one has quite a numb nerve.
In addition to the monotone, we're given another two bottles of nightmare fuel in the Battle of Solomon. First, the Earth Federation's solar reflector array, Solar System, fires a giant beam that decimates the main gate of the fortress as well as all the Zeon units that attempt to sortie there, burning them to ashes. Then, Dozle Zabi's Big Zam retaliates, frying the Federation fleet in the same way.
SEED was the first Gundam series to be broadcast in high definition, and to celebrate, the producers apparently decided to up the gore and horror content beyond anything previously attempted. Yikes.
Several death scenes deserve special mention:
In the original SEED series Yzak Joule destroys a spacecraft carrying Heliopolis refugees including a little girl that befriended Kira. This scene became more disturbing in the HD rerelease of the series where we the the people inside the spacecraft a second before dying.
Nicol Amalfi jumps out to save his friend Athrun from Kira's BFS. He succeeds in a sense, but is not only bisected by a massive beam sword in the process, he has enough time to shout for Athrun to run away with the sword still in his gut before blood fills his visor, and his Gundam explodes.
Tolle Koenig tries doing the same thing for Kira, only this time in a plane. It accomplishes little, but he gets the gruesome honor of dying via a Gundam shield getting boomeranged into his cockpit and decapitating him.
In Gundam SEED Destiny, a pilot of a Dagger L is shown getting the Impulse's combat knife slammed into his cockpit, decapitating him and spilling blood over the massive blade.
Djibril gets a particularly fitting one. As he prepares to abandon his men on the Lunar base the same way he did at Heaven's Base, Rey Za Burrel bursts out of nowhere in the Legend and sends two sword DRAGOONS through the bridge of the Girty Lue. We get a rather satisfying picture of Djibril screaming in agony and terror as his body is ripped apart by the beams.
There was also Mudie Holcroft's death in the Gundam Seed Stargazer OVA, where a pack of BuCUE's dog-piled her mobile suit and stabbed her continually with their beam fangs. Her screams made it all the more disturbing.
The ruins of Junius Seven are pretty gruesome. It's implied to be a lot worse than shown, but one scene shows the corpse of a mother still futilely shielding her baby's body even after they've been drifting in space for nearly a year. Given just how many people lived on the PLANT, there were probably entire regions littered with scenes like this.
The Cyclops self-destruct system (a high-powered microwave weapon) and gamma ray Kill Sat GENESIS. Microwaves heat water, and given that the human body is about 60% water by weight, you can imagine what it does to people caught in its area of effect. GENESIS is basically Rule of Scary. When it's fired into the Earth Alliance fleet in episode 48, you get to see the crews of the ships screaming and writhing for about a second, as their space suits expand and pop. It's even worse when the weapon hits an Alliance lunar base, as we get to see several Bridge Bunnies at their communications stations, clutching at their chests before blood sprays from their mouths and nostrils, and then they burst like balloons.
The end of the Battle of Panama gets scary once the ZAFT soldiers, still enraged about JOSH-A, begin massacring the surrendering OMNI prisoners. The screams of the helpless soldiers getting shot up by GINN rifles and small arms is pretty sickening, along with a few images of their mutilated corpses for added effect.
The corpses we don't see are going to be even worse. Considering that the GINN's assault rifle fires 76mm rounds, we're well into Chunky Salsa Rule territory here.
Mendel. Dear Lord Mendel. That place is implicit horror through the roof. The experiments held there, the blind ambition of the scientists that caused them to basically slaughter children For Science!, and the still functioning artificial wombs, still showing the embryo ultrasounds, is just sickening to the core. It doesn't help that it's Rau Le Creuset who is narrating just what went down here, managing to make himself look more like a victim than a villain, once he recounts how he was born.
And that's without getting into just how terrifying the leaders on both sides are. Or Rau Le Creuset who is one of the most chillingly realistic Omnicidal Maniacs ever presented by a TV show.
This deserves explanation. When Shinn and Rey first enter the place, Rey has a full biological and nervous breakdown. Later, when the teams sweep in and start exploring, they find both scientists and kids who haven't even entered puberty yet, all dead from infighting. Some of them were still in tubes when they were shot or stabbed. The last room is filled with brains, all stuffed into jars and jammed with probes, along with a computer detailing just what they did there.
Particularly harrowing is the fate of Descartes Sherman, trapped in the cockpit of his mobile armor, as we see the crystals growing out of the skin of his face (even coming out of his mouth), until they shatter his helmet, all while he screams in fear and pain.
The Unknown Enemies in Gundam AGE, whose sole purpose is to kill and kill and destroy everything in their path, and blowing up a colony, killing millions and making millions homeless. This also causes a revenge fuel in the main casts of the show.
Thought the big twist revealing that the UE are Human All Along would make them much less horrifying? Nope, it actually makes them worse. Think about it: since the Vagans were living in a planet that has a weak magnetic field that can't protect them from cosmic radiation, they most likely were killing each other for 150 years over scarce resources (later confirmed to be true by Zeheart). Then a dictator, Ezelcant, uses their desperation to unite them under a promise of capturing Earth Sphere, which has been at peace for 100 years with advanced mobile suit technologies banned by treaty. Hate to pull a Godwin but, much like how Zeon resembles Nazi Germany, Vagan is the second coming of North Korea. Being personality-cult fanatics who blow all their resources on military technology at the expense of social development (as seen in Episodes 29 and 37) clinches it.
And their ace in the hole? DesilGalette. A Deliberately Cute Child who was always bad news to Flit, he reveals his true colors in Episode 13. From killing his own comrades to pressing Yurin to make her fight for the UE, Desil has cemented himself as a horrifying villain in the series.
One episode after that, he kills Yurin and mocks her, saying that she was nothing but a toy at his own disposal. The lack of any empathy is truly unnerving... from a seven year old, no less!
Gundam AGE probably wouldn't have its own folder in this Nightmare Fuel page if it weren't for Desil being such a one-man horror show. Yup, he's JUST THAT SCARY.
Heck, you can thank Desil for starting a Nightmare Fuel page for the entire franchise.
Imagine being chained to the cockpit of a UE mobile suit as an Ax-CrazyBlood Knight controls the functions of that mobile suit. Then, when you see your loved one on the battlefield, the system controlled by the Blood Knight orders your mobile suit to open fire on your loved one against your will. And all you could do is watch in horror. That is what happens to Yurin when Desil had her locked up in the cockpit of the Farsia mobile suit in Episode 14.
Grodek getting jumped and stabbed to death by Arabel Zoi in Episode 24. The smile Arabel exhibits while killing Grodek in the middle of a dark, wet alleyway will haunt you for days.
In Episode 26, Flit reveals his trump card, a Kill Sat known as the Photon Ring. Much like the GENESIS, it vaporizes any unprotected Vagan that's in its path. Combined with Flit's eternal hatred of the nation that killed both his parents and Yurin and... well, you do the math.
In Episode 27,Where Daz attempted to taking Flit with him,his face actually looks even scarier than Desil!
Flit's coup d'etat in Episode 28. While it's one thing to remove traitors in the government, it's another to eliminate those who would oppose outright genocide of the Vagans. Moreover, seeing a cold Flit imposed on the terrified faces of the uprooted officials shows how disturbing his plan is.
We witness in Episode 30 a Vagan battleship wrecking havoc on an entire city, wiping out innocent lives; we even get to witness a mother bearing a baby vaporized by fire! All of this terror makes the AGE-3 vaporizing the crew of the ship with its new BFG, which would have also qualified as one Nightmare Fuel, all the much more satisfying.
We finally get to see life in Vagan. Many citizens live in poverty and are unable to get their hands on medicine for the disease caused by Mars Rays. And even if they could it would only be a temporary measure—Ezelcant himself has just six months to live, which will leave his wife with a dead child and husband. The disease hits everyone regardless of their age or social status. Conditions are so hopeless and dehumanizing that most people gradually shut off their emotions as they get older, except for resentment towards the Federation that abandoned them. For Vagan, crossing the Despair Event Horizon is not an event in one's life, itistheir life.
From the new opening sequence, there's this shadowy...thing. It will no doubt be far less frightening when we see it in the light, but at the moment, well, just LOOK at it.◊
If you look closely at the second opening title sequence for Gundam Build Fighters, we see Chairman Mashita and his aide Baker standing in a room filled with Mobile Suits from various gundam series, and they obviously look quite sinister-looking (One of them is the Master Gundam, no less!). THEN we get a close-up look of the Chairman and the Mobile Suit behind him stops at Gundam Exia with its red optics glowing, and cue the Chairman making a maniacal grin. It's really unsettling.
In Episode 14, we see Chairman Mashita's aide Baker essentially hires a mobile suit equivalent of a hired gun (Mr C.) to eliminate Sei and Reji's Star Build Strike Gundam and he would stop at nothing to hinder their way and prevent them from reaching the finals. And Sei and Reji were nearly eliminated from the competition due to Mr C.'s intervention, he was clearly celebrating in his private chambers.
That's not mentioning he unleashes a 1/48 Mega Size Zaku II to target Star Build Strike Gundam in episode 12.
It has been revealed in Episode 15 that there is a mafia that is more than willing to kill off any player pilot's mobile suit for a price.
A nightmare fuel moment was avoided in episode 6 but it's still scary to think about. Imagine for a moment if episode 6 epic fight wasn't in the Gundam Build Fighter universe but in the Cosmic Era or Universal Century. That slash the Zaku Amazing did in the center of Build Strike would of killed the pilot. It's kind of a sobering thought.
If that's not enough, the Embody System in episode 20 is a mixture of the Berserker System and Psycomet Mu-szell. Making the system at full output not only Mind Rape her, but also cause her to keep destroying Fenice even through Fellini had conceded from the battle. When Aila Jyrkiainen's Qubeley Papillon reveals its glowing Tron Lines, you know you are terribly, horribly screwed as an opponent.
Take one look at Exia Dark Matter, and ask yourself whether you will be afraid when this Mobile Suit appear in gunpla battle. Hint: It's RED AND BLACK, AND LOOKS DAMN EVIL.
