I had this idea last night, in one of incarnations of Dan she is a big and scary amazon,this is her in he casual edgy clothes, this is not he real armor. c:

The idea behind these amazons is that they are yet another failed attempt of mankind to create super soldiers for their endless wars, but this time they accidentally created an entire new stable species that instead of hating other species as it was intended, all their genetic hatred is directed towards baseline humans.
"Oh they are big women!? they surely have snu snu with human men to please the male cis het audience right?" No.whenever they raid human settlements the defeated men is butchered for their flesh and skins and the women are taken as slaves, amazonians are all women but half of them have cocks, they are capable of reproducing by themselves, they dont need pathetic human men.
"isn't this theme of humans failing to make super soldier a repeated theme on your stories?" yes because it's a story about cycles and mistakes that repeat itself, and humans are xenophobic warmongers by nature so they would be the species doing everything to create something to kill other species.
