I also, I am once again saying that I'm kind of sick of people acting like Gundam X has to be the last word on Newtypes as a concept.
I put this as kind of an aside on the last page but I really think every AU has its own take and spin on Newtypes, each addressing one or more parts of the idea.
G Gundam probably has the least to say about it since it's more about martial arts cultivation, and the closest we have to anything like a Newtype paradigm is Allenby standing in for the parade of exploited child soldiers with go-crazy buttons in their cockpit. This was the first one though and wanted to be as different as possible from the UC.
Wing also only sorta has nods in the direction of Newtypes with Quatre's special abilities and the "Heart of Space" shtick. It doesn't really answer any questions but does use the motif of a kid learning to understand the other on a holistic level as a character arc element, and just kind of lets that simmer while greater geopolitics are resolved through...mainly optimism about humanity as a whole getting exhausted about war. Interestingly, there's a "Deikun equivalent" in the original, backstory Heero Yuy, but his ideology was entirely unrelated to anything that could be considered a Newtype parallel.
X was the first AU to really focus on Newtypes and as far as text in the show goes the only one to refer to them by name, which is why it's easy to do the frustrating thing tank mentions. It's also very stark and on the nose in its refutation of the subject, as I mentioned earlier, but gives an optimistic spin in saying that the real Newtypes aren't the ones with special powers, but the ones who actually show kindness.
Turn A we've been discussing at length but I personally feel it's good to look at it as a distant epilogue of UC that takes a similar stance to Wing and X in saying that people can choose to be better regardless of any power or ability and that looking to the powerful to "guide" humanity is needless and a mistake.
SEED does a sort of interesting thing where there's exactly two literal Newtypes (called something else) but the actual conflict of the story centers around humans self-uplifting through gene therapy and whether those genetically optimized people should rule the world or be purged as abominations, with the continuity eventually reasonably settling on "neither" while the antagonists are more about fantasy eugenics in one direction or the other than even the most rabid UC contolist.
00 is perhaps the most unironic and idealistic in its embrace of Newtypes as an ideological aspiration, with Deikun's words effectively transferred to Aeolia Schoenberg as a means of humanity transcending its limits, not just to create peace amongst itself, but to be able to join interstellar, interspecies civilization, as seen in the movie. It's very much a deliberate homage to the novel Childhood's End where humanity is indeed destined to evolve into something greater, and that's treated as a positive and aspirational thing for the whole species, rather than something to divide humanity into haves and have-nots. (Also hilariously Aeolia and Celestial Being suppressed space colonization in the backstory because they new that major space settlement before mass Innovation would divide humanity further). Also there's separately not-Coordinators masquerading as the not-Newtypes which is the ACTUAL main conflict of the series which to me muddied the waters a fair bit. Also really not clear what separated the precognitives from the Innovators other than no one writing Allelujah's plot talking to anyone else in the writer's room. 00 is weird.
Gundam Age is just extremely funny because they did Newtypes again down to the letter and then the big bad proclaims that rather than evolution, X-rounders are exhibiting
atavism to a pre-civilized state because all those boosted combat abilities are surely adaptations to a law of the jungle situation, right?
Finally we have both IBO and G-Witch going back to the SEED well of rather than "evolution", the special powers of the setting being a result of mild transhumanism, in these cases cybernetics rather than gene therapy. In both settings, the power granted to the cyborgs is vilified, but for different reasons. IBO ends up being mainly a commentary on UC's glorification, in and out of universe, of empowered child soldiers and the consequences of that, while G-Witch doesn't really have a political message about its "witches" per se other than perhaps pointing out that getting mad at the people using brain eating cybernetics for dying is kind of victim-blamey and its really (obviously) the military industrial complex's fault and we should all just calm down and stop turning every technological breakthrough into a new kind of gun.
