User blog:MonsterCollecter/Monster Girl Original: Warforged

Deep in a tropical jungle near the equator, there was a powerful civilization of magic-wielding humans. Thanks to their magically-enhanced armor, they were capable of defeating even the most powerful monsters during the reign of the previous Demon Lord, and when the new Demon Lord rose to power, they intended to continue that. But they tried too hard.

Upon discovering the intentions of the new Demon Lord, the country's head sorcerer attempted a massive spell, one which would prevent entrance to the capitol by any monster, and create a safe zone. However, the spell failed, and the resulting backfire sent a wave of uncontrolled magic surging through the country. Warriors had been preparing for a huge campaign, intended to confront the Demon Lord herself, and the magic in their armor combined with the wave from the failed spell. Men and women alike were fused with their suits, making the metal part of their bodies, and removing their status as 'humans'. They were changed into monsters, and combined with the Demon Lord's influence, the warriors who had been male were turned into females. Their new instinct of 'reproduce' was first fulfilled with the remainder of the country's inhabitants. The same sorcerer who had first mistakenly caused this had been changed himself, but retained all his magical knowledge, including the ability to analyze spells. The new sorceress recreated the mistaken spell, and used it to fuse the rest of her citizens with new armor.

While these new monster girls, who call themselves 'Warforged' for their history and how they came to be, are still subject to the same instincts and needs as any other, they still remember their goal to confront the Demon Lord. They have bult an army, and they plan to march for the Demon Realm, though now their purpose is to find a way to give birth to males again.
