The show is about a bunch of naive and/or power-hungry fools pushing the solar system into an apocalyptic war, and it wouldn't work if they didn't make the war bit scary.
- The G-Self Perfect Pack's photon torpedo launcher, which may be the most terrifying weapon in the show. It is a cloud of drifting, sparkling antimatter particles that simply erase anything they touch. The only time we see it fire, Bellri literally dissolves an entire Wuxia squadron. And Bellri wasn't even using the system at full power specifically to avoid killing the pilots! It disturbs Bellri so much he never uses it again after the first time.
- The movies upped the ante. With just the single press of a button, Bellri turns the whole battlefield into a matter disintegrating minefield, with the proverbial mines being completely invisible. You have no idea they are there until you run into one, and by then it's too late to do anything. And this time they do not discriminate where they hit, with pilots being confused and terrified as their mobile suits just vanish from under them before they themselves soon follow. Everyone watching this, friend and foe alike, are utterly dumbstruck with Bellri himself who, unlike his TV series counterpart, was utterly horrified by the whole thing, hearing the screams of the dead even after it was over. It is to the point that he tried to get rid of the Perfect Pack out of fear what it was capable of.
- Barara's rampage with the Yggdrasil in episode 24. It is a colossal mobile armor that attacks by sprouting root like beams that home in on enemies from all directions. While simple, the attack closes off all routes of escape, meaning you WILL die if you're in its effective range.
- The concept of the Kuntala. While it is never spelled out to us, the clear implication is they are descendants of a class of people who were born to be eaten for food during a time where food was incredibly scarce. Even more so, it is implied that the practice is still carried out in other parts of the world.
- The Gundam G-Lucifer deserves a special mention. Even though it looks like what would normally be a traditional final boss mech from any other Gundam series, it is part of the Megafauna's crew. So normally it should be a target for any of its enemies. But in every battle it's been in, almose everyone, especially the G-IT Lab (who built the thing), avoids directly engaging with it in battle. The reason for this is because it is an another mobile suit built using Hermes blueprints that boasts incredibly high performance, and is equipped with 3 funnels capable of clearing out entire fleets of enemies with ease. But this isn't the scariest thing about it. According to Tomino himself, The unit is equipped with a fully functional Moonlight Butterfly System, the same type used in Turn A Gundam, on a smaller scale and with all the necessary requirements to use it. Considering the main usage of said weapon is to turn anything in its radius into sand via nanomachines, and the ones seen in Turn A could reach all the way to Jupiter, it is pretty obvious why nobody wants to get close to it; it is an almost guaranteed death sentence for them and possibly the entire fleet. Essentially, while it doesn't do much, it is the strongest mobile suit involved in the war, and nobody, ESPECIALLY the Labs (who know about all its capabilities), wants it pointed towards them.
- In the Blu-Ray release, we actually get to see Raraiya use the Moonlight Butterfly. It disables a Towasangan battleship at range with little to no effort. Imagine that used on an entire army.
