Firstly, a warning.
Disturbing contents and spoilers up ahead!
People may not notice it, but Gundam SEED and Gundam SEED Destiny are pretty twisted in their own ways. Sure, they are not as macho as the rest of the series. I mean the fast-paced set-piece battle we saw in Gundam Wing was toned down in SEED. And we rarely see any display of machismo that Gundam G flexed so much. Just look at Kira Yamato. So effeminate, that haters pointed out that his sole proof of manhood was his plot armor.
