I recently returned to the fandom as an adult, and found your blog a few days ago. I find it incredible; I've already read it up to the initial post, and I'm really excited that, as adults, there's still so much to read.
I'm also surprised by how regularly the fanfics continue to appear, although I do agree with many of the things you've mentioned, especially regarding the characters' personalities.
Now, all of this was a prelude to telling you something I've been seeing in fanfics recently (I don't know if they're from the same writing circle or something) that resonated with your post about how GW isn't realistic, although it is plausible (it is science fiction, after all). Well, what's constantly repeated is that some of the pilots are the way they are (super strong, super agile, ultra-durable) due to enhancements implemented by scientists. Or even through mutations acquired due to the malfunctioning of their colonies, as in Duo's case (although that seems more like an excuse for his violet eyes in the fanon, it's still striking how often it's repeated).
What do you think about this? Do you think it would be plausible for them to be physically or genetically modified? (although there isn't necessarily evidence in canon).
Thank you for enjoying my blog. :) Catching up to the present is pretty easy considering my stellar posting schedule of once in a blue moon, haha.
As for your query, I recently waded through Frozen Teardrop to find out what the deal was with the Meilan chapters I had previously ignored, and Sumizawa actually wrote that Wufei is, genetically, the only person Master O found who could pilot a Tallgeese type suit because his body is extra durable and stuff.
Which contradicts canon in 40 different ways with Zechs mastering the suit eventually, but Sumizawa has established well how little he cares about canon ever since joining the fic writers.
Why do I even mention this? Because FT has everyone with nanomachines up their noses, which would easily lend itself to sci-fi genetic modification shenanigans that could have explained super soldier Heero. In fact, I did not read the chapter with Heero and his clone, so who knows, maybe Sumizawa did include it.
Though he also included Wufei basically randomly being a tough, little cookie. So not much of a case for consistency to be made here...
But I can see why proper fic writers would go that route. After all, Heero fell off a cliff and despite everyone, from Duo to Sally to Relena, thinking he'd be dead, he got up having suffered just a broken bone.
So yeah, there is definitely something up with him, at least.
As for the other pilots, it's implied by Zechs I think it was that the Gundam pilots' training is what gives them their endurance and skill. If you really look at their skill sets, I don't think they need enhancements or genetic modification for what they can do. Quatre can go entire battles while bleeding, sure, but he ends up hospitalized afterwards. Duo has insane spatial awareness, which might as well be a natural trait. His combat skills, for instance, suck. Wufei hails from a colony where everyone was Bruce Lee, of course he knows how to control his body perfectly. And Trowa being an acrobat lends itself to greater strength, balance and agility. These are acquired traits. As for his incredible skill in a Leo, that's a very clever nod to his experience in the mercenary unit, so very much in line with the writing.
Do I personally think J meddled with Heero's body? Hmm I guess...? I'm not opposed to the idea. The thing that I dislike is that the more artificial Heero's abilities become, the cheaper they are compared to the other pilots' skills to me.
Heero isn't impressive if his keen hearing, for example, is because he was given drugs or genetically modified or whatever. Duo pulls off perfect marksmanship without that kind of aid. Wufei evidently worked for his prowess. So I'm okay with Heero being stupidly strong and able to tank falling off a cliff due to artificial enhancements. But everything beyond that would make him cheap to me.
He'd be like Kira from Seed. A boring Mary Sue who only got that status because of someone else's skill, not his own.
