ΛLDNOΛH.ZERO

Aldnoah.Zero is a Mecha Anime about Martians invading the Earth. The Martians are, however, not aliens but humans who happened to discover ancient alien tech on Mars. The Terrans are stuck as the underdogs in the series, forced to outsmart the Martians, who have insane technology.
The series has a strange storyline (downright contrived…) and weird worldbuilding, for good measure.

I thought the first season was pretty good, and I enjoyed it quite a bit. The beginning of the story is particularly well-put together, introducing the world and characters quite well. The relationship between the Martians and the Terrans (alongside an introduction to the power-imbalance) is presented to the audience well, allowing the audience to quickly grasp the situation. From the beginning of the war, the Martians come off as an overwhelming force and a terrifying threat to the Terrans. The opening move with their landing castles is so beautiful, it continues to bring me to tears.
Unfortunately, the perceived threat-level of the Martians decreases fast over the course of the series. This mostly stems from the fact the Martians are morons - an obvious and serious writing flaw.
I found the insert songs to be awkwardly inserted and poorly timed.
The second season pretends the end of the first season doesn’t happen by undoing most of it. Surprisingly, I didn’t mind this as much as I expected to at the time, but it irritates me more as time goes on. This is mostly because the ending of the first season is quite daring…and then the second season just undoes it. I’d compare it to Code Geass in this regard, as I believe it achieves the transition from the first season’s cliffhanger ending to the start of the second season better than Aldnoah.Zero. The second season generally fails to make the Martians as threatening as they were at the very beginning of the series. While there is a brief moment where the Martians start regaining their threat level, the series brings back the MC after his little break, and him and his robot eye completely destroy the Martians. I’d say this is a shame, as the series could have been much better in this regard.
I do think I overall still like the series, and I would recommend giving it a watch.

The Holy Empire of Vers is an absolute feudal monarchical empire located on Mars. I have no idea as to how much of Mars they actually control, but it doesn’t really matter, since they’re the only ones there.
The twist is that the feudal system is built around Aldnoah, rather than land ownership.

The Moon fucking exploded and now, it’s controlled by the Martians. The parts of the Moon that were blown off now form a ring around the Earth. That ring contains a number of stations owned by Martians and Terrans^A), which then fight against each-other.
The Moon used to be where the hyper-gate was located - the hyper-gate being a portal device. The hyper-gate is what allowed the first colonists to go to Mars^B), and it was later used by the Martians to start the invasion of Earth. However, the hyper-gate ended up getting overloaded by the Martians due to the insane size of their fleet. The result was an explosion that destroyed part of the Moon, the hyper-gate itself, a big chunk of the Martian invasion force, and their current Emperor - this final loss caused the previous Emperor to come out of retirement.
The Martians had no other means of quickly going to and from Mars at the time, which left the remnants of the invasion force in an awkward and isolated position. These remnants became the Orbital Knights.

Aldnoah is a mysterious technology that was left behind on Mars by a long dead alien race. To summarize what it is: it’s magic, and it can do almost anything. Despite this, the alien species that invented it did end up going extinct and the Martians can’t seem to solve their problems like water shortage, no atmosphere, not enough food, etc. This is odd, if we’re looking at it from a meta perspective, since Aldnoah is presented as a miracle technology.
Aldnoah appears to be something like an engine, rather than some collection of technologies (or a sci-fi name for magic). Exactly how it messes with the laws of physics is another thing entirely.
Aldnoah can only be activated by members of the Imperial family and those who are loyal to them. Only the Imperial family can activate it because the first Emperor was the first person to touch Aldnoah, which then registered his DNA, allowing only him and his family to activate and deactivate Aldnoah. If the person responsible for Aldnoah dies, or almost dies, then all the Aldnoah drives they activated will deactivate.
Now ‘loyalty’ means that a transfer of DNA must occur…although the series is vague about this, so it’s possible that there’s another method. Basically, a transfer of DNA needs to occur. If a member of the Imperial family kisses someone else, then that person gains the ability to activate Aldnoah. There’s also an implication that this can be taken away, but I don’t know how that would work.
There’s also an issue with this activation method, as, apparently, it’s possible to gain the ability to activate Aldnoah without the other party intending it. This is because Inaho gains the ability from the princess while he was performing CPR on her…and she was unconscious at the time^C). This raises several questions about the worldbuilding of the series - such as why the Emperor is even listened to in the first place…it may be easier to just lock him up and drink his blood or something to that effect. The fact this doesn’t happen means that there is a way for the Emperor to take the power away…but we don’t know what it is.

Maybe I’ll remove this section entirely.
