Again just like his other works, there is a Nightmare Fuel section.
- Ledo's description of what happens to Alliance members who can no longer serve as soldiers—they're "retired" in the Blade Runner sense. Made especially unnerving in how he tells this to a gravely ill boy and his sister as if it's completely normal, which it is in his world. The Alliance is looking worse with each episode...however, to be fair, Chamber mentions in the first episode that no known Earth-like planets exist, or at least have been found by the Galactic Alliance despite having spread out quite far in the galaxy. Which probably means that resources may be scarce. On top of that, they're fighting what seems to be a losing war against the Hideauze, despite their advanced technology compared to those living on Earth. So Ledo was just using Brutal Honesty, since that's all he's known in his short life, and to him, keeping someone like Bevel alive would mean less resources going towards someone who could fight against the Hideauze.
- Looking at the shots of the destroyed colonies during the battle scenes in Episode 1, major Fridge Horror sets in when you see some huge holes punctured in their glass domes. The air supply was probably all sucked out into space, along with many people. Remember when Ranka was almost sucked into space in Macross Frontier? Imagine that happening to perhaps thousands of people all at once.
- Imagine Chamber's attack in Episode 2 from the Pirates' side. Beams of light come from the sky and destroy your entire fleet. Then, all of a sudden, the guys in front of you suddenly turn into puffs of ash, and you still have no idea wha--
- Episode 5, while Played for Laughs. Ledo's encounters with the gay bar employees can come across as a bit disturbing. Not only do they chase him down after he's given a very clear indication that he wants them to leave him alone. They're actions in pursuing him end up not only damaging a ladder and endangering a teenager, but nearly getting themselves killed in the process as well.
- Episode 9. Ledo enters the Hideauze nest and spies a "nursery" filled with babies. Despite how they look somewhat like human embryos, he proceeds to burn them alive, and we hear them scream. Then Ledo finally has to ask what's really going on here, and with only token reluctance, Chamber shows him an archive news clip detailing The Reveal...Hideauze are biomechanically evolved humans fighting over access to space with the humans who decided to leave the rapidly freezing Earth. A baby Hideauze then swims up to Ledo and just acts like a curious child. Chamber then proceeds to take initiative and crush it in his bare hands without Ledo's command, and Ledo proceeds to scream in existential anguish. Cut to ChouCho's calming ED.
- Immediately before the actual reveal, Chamber's "reluctance" is because the information just scanned is listed classified at the highest level of the GA. That would only be possible is that the GA leadership knows exactly what the Hideauze are. The entire war is being fought by their conscript soldiers who don't have the knowledge that their leaders do - that the Hideauze are of human descent.
- Episode 12. In Striker's Earth-based Alliance cult, "unfit" Earthlings are disposed of much like back in space; dumped over the side of the ship. And it's treated as a holy religious ceremony in honor of their "god" Striker. Ledo's also treated to a boy being dumped who looks strangely happy about his ritualistic murder. When he reminds Ledo of Bevel and his brother, he finally decides to take action against his former masters.
- The revelation that pilots can merge their nervous systems with their mechas for maximum performance. Ledo's cry, "Just go and eat me!" raises some more Fridge Horror: is that what happened to Kugel? Taking things further, is that what happens to all GA mecha pilots? And taking things ''even'' further, is the GA government actually run by AI? (which might make sense given that the Alliance's alphabet appears to be a very artificial looking set of blocks, almost like binary representation of something...) Gen reminds us that you don't need to kill them all to leave some major Fridge Horror.
- The fact that Ledo says, "absorb me" in the English dub, sounds more disturbing rather than less.
- In part two of the OVA Meguru Kouro, Haruka, Reema's backstory is further explored. She's actually a spy from an unnamed land based country, and originally wanted to have Ledo go back with her to further develop a mecha her country discovered after her initial plans to recruit Kugel failed. In one scene she mentions that her country has been at war for centuries, suggesting that not all things went well for everyone on Earth. When a navy from her country attacks the boats containing her and two of her comrades, they are using ships that are on par with what Gargantia's fleet is using, suggesting that they lost the capabilities to use the advanced technology that was left behind on Earth after the Continental Union and the Evolvers took their war into space. And it unfortunately hints at the fact that humans are still actively killing each other on Earth.
