The aliens put their chest-busting things in other races.
Changelings?
Vampires and werewolves and undead of all kinds.
Cybermen (though it's weird. If you have the technology to mass-manufacture your race, why not do it? I call buggy AI directives on that one).
Depends on the Cyberman tho. Sometimes they were human brains and nervous systems in a metal suit, one time everyone's Air Pods started mind controlling them(I'm almost not kidding), sometimes they're just a different race...

The way it's depicted in Goblin Slayer makes it extremely hard to believe. A race that can only survive by breeding with another(sapient race) would be exterminated if they acted like goblins. A 'monster' race that constantly attacks and rapes you? You would sweep the land completely with the entirety of the nation's army, as many times as it takes. After a few centuries, there would be no chance of survival.

It's another matter entirely if they use the seduction route instead of the rape route. Nymphs from Greek mythology are a big one for me. It helps that they're long lived, so they don't actually need to reproduce to keep their numbers up. A race that demonstrated utility to the race they depend on for survival might be able to integrate into their culture, or at least raise a small village of 'admirers' who willingly help them in exchange for protection/services.

It was mentioned already, but races that are born from other races non-sexually like Vampires and Werewolves are in this as well. It's actually a big plot hole, half the time... They treat the races they come from like garbage, even though their own species will go extinct if the humans do. It's kind of justified in that they're designed by 'evil being' to destroy humanity, so the preservation of their species isn't a real issue. Still annoying though, especially in settings where they aren't a created race.

Additionally, races that can reproduce with other races but also their own are exceptionally practical. Alraune and Succubi fall into that category, in my story at least. I've also seen dragons fall into this one several times. The problem being that you might need to set limits on what they can breed with... Though Rising of the Shield Hero is one of the dragon examples that doesn't set any limits. And apparently they don't have any problem breeding with random animals or... like trees and stuff.



Oh, for the Cybermen, they subvert humans out of pity, not necessity. They think emotions are a flaw, and they want to save humanity from their flaws. In a twisted bit of flawed AI logic.

I dunno man. It depends on the level of technological and military progress of the specific sapient race and the circumstances of individual settlements. Nowadays you can have dogs biting people to death en mass in packs and terrorising neighbourhoods and nobody does shit. You can have insects eating all your food and there's nothing you can do. An intelligent race of evil and brutal monsters that spread like a plague? I doubt even we could manage to contain it without enough loss, and at that point, I'd say we would just accept it as something that just happens, and we would just say "oh that's terrible" while thinking to ourselves "well, it didn't happen to me, and it isn't really my problem". It would become just a part of life and call it quits.

Wouldn’t really work, unless some made something to do that. So god specific making them, but in evolution terms hell to the fuck no. Most races that do that are parasites, or bug who use a host as flesh shield and lunch box for there kids
You too.
Doesn't make sense biologically. But that doesn't stop dolphins now does it?

Unless you're using the victim as a food source for the young, like parasitic wasps.
See, it gotta be make like The world god did that, but wouldn’t that just make em’ a big d*ck

With that Goblin Slayer thing of monsters that need to breed with other races to reproduce, I’ve been wondering if anyone of you have your own take on monsters like that?
I mean, it seems it’s always goblins and orcs, so why not a made-up monster or something like that?
Dryads, water nymphs and bitches are all single gender creatures that either require other races to breed or claim they can breed with air.

I always thought of the stories where a specific "monster race" needs another race to breed as sort of Virus's made to ruin that specific race. Oh I know of a similar one: https://www.cnbc.com/2017/07/22/scientists-breed-a-mosquito-vs-mosquito-war-to-eradicate-zika.html
So Goblins and Orcs are there to reduce the population of the world as there are to many of them.
That is one shitty and cruel way for the supposedly omnipotent gods to go about this.
Like, how about just reducing their reproduction rate to a stable level, or create more room for them to live in.

Or even, maybe just this, animals that don’t fuck you, and just kill and eat you.

I forgot one of the biggest points with unisex races.

Female races would be far more likely than male, since they can have a one night stand and disappear with the baby. Even if they do kidnap men, any retribution that comes for them would have less chance of getting the baby killed. Not to mention men are usually considered 'disposable' compared to women, so it's unlikely that said retribution would be as heavy as what would be sent after a goblin-like race.

A male race would either need to get a girl to accept them and carry the child willingly, or capture the girl and still somehow keep her healthy(ie, not starved or suicidal). Then they'd have to deal with relations coming to get her back. It's so much more difficult for a male race to survive that it's basically completely implausible. They'd be better off having the standard two gender race, an asexual method, or going fully parasitic like xenomorphs(which are also highly impractical since they kill the race they depend on for survival).

does this count? a lot of plants follow this strategy of luring an insect to have it carry their pollen. so technically, these plants need another race to reproduce

One of the original myths about succubi was that the succubus would have sex with a human male, stealing their semen, and then turn into an incubus and have sex with a human girl, thus creating a half-demon with the repossessed semen. (Probably as an explanation for infidelity.) It was overcomplicated, but yes, it counts.:blob_teehee: Well, sort of. Most plants are technically hermaphrodites.

In my current fiction, the monster races have peculiar origins ranging from bacteria, alien life forms, and mutated animals. Easy enough to understand right?

The goblin kind in it is kinda unique, born from my imagination nonetheless. They came from bacterias that eventually mutated to humanoid shapes. This is the result of their cumulative evolution. All goblins are males, and they can procreate with any species as long as it is a female. Goblin infants when born rip themselves from their mother's wombs as they revel in eating her flesh.

The monster kind won't appear in the earlier parts, but their presence will be mentioned in some earlier parts.
The idea of the novel is about an unpublished novel called 'Mutagenic Medieval' where the author transmigrates to the novel.

In the case of intelligent design, the objective may not be viability, but terrorism. Say hello to the chrysalid.

They, like xenomorphs, attack and impregnate their targets at the same time, which results in the death of the host (or do they impregnate already dead humans? I don't recall which.) as the baby chrysalid "emerges" from their seedbed after a rapid gestation period of minutes.

Alternatively, you can slant the trope a bit and have other races be useful for outside-the-box adaptation with a magical/soft scifi race borrowing the best traits of their mates and/or victims or at least being capable of hybridization ala the Asari, the Tyrranids, and DnD dragons (though I believe someone mentioned them already).

The "how" in these cases aren't really that important, the "why" is. Because that can be played with for very interesting story points.
