It depends on authors really. I'm a writer and my male spider-shifter actually has a female spider inside, so he can be pregnant in his spider form. And to answer your question about his sister, hmm, you know of Mendel's Genetic Laws right? Not all offsprings get the same genetic traits in some cases.
Oh
Mate this is fiction. I can see where your coming from though. In the universe the author is created it's possible for people with lycan blood to have 2 different genders. I think it has similar aspects to omegaverse but it's not the same. Just like in an omegaverse it's very likely that if you are human male but female lycan that the uterus is connected to the anus. Anyway all we can do is guess unless the author decides to explain it in detail either in the manhwa or in a note.
Male human with a female spider inside of him. That is interesting. How do you explain it? I think, it needs to be explained properly in books. Like in Loki's case. Loki was a male God but he was also a shapeshifter who could even change his gender (as he did in order to distract a male horse by changing himself into a female horse, which eventually led to Loki giving birth to a baby horse with 8 legs). In this story, however, we see a male, who was always a male, and who never changed, suddenly being announced as a female lycan...
I seriously hope there is going to be an explanation. With some complexity involved. Not just - he's a human male who turns into a werewolf and undergoes a gender transformation with every transformation. End of story. - That's just so... simple.
Yes, I know about the Mendel's Genetic Laws. I forgot the fact that he's not a pure blood werewolf when I wrote that comment. Still... it would be cool if his sister was a werewolf too. Kinda hoped for it.
A dude with a penis and uterus in his anus would be an omega from an omegaverse, no? But this is a male human with a female werewolf form (at least I got that impression). This would mean that he switches his gender during every transformation. And also that can he get pregnant only in his werewolf form, because he's a woman in that form... This is getting so confusing.
It's just the way the author has done their universe. you have to remember this is fiction and comes from the authors imagination. Just because a guy has a uterus and a penis does not make him an omega. Yes this is true for omegaverse story's but this isn't an omegaverse. This is a story that the author has come up with and because it comes from her imagination. Switching gender during human transformation could be the way the author is going with this but it might not be. Again this is fiction so there is not gonna always be a logical reasoning to biology of the characters. Also omegaverse is part of the category mpreg. You can have an mpreg manga without it being omegaverse you know? I think your just thinking to logically about it and being too constricting with themes in Mangas.
A dude with a penis and a uterus in his anus would be an omega from and omegaverse
But this isn't an omegaverse this is the authors own idea for a story. It's completely made up.
I'm not sure how else to explain it. That's the best way that I could.
I know it's just a fiction. Can't help it though, I'm questioning new things and concepts.
This is the first time I've read a manga with this type of a character, that is not "labelled" as an omega (cause only omega always fitted that role)... Well, actually it's the second time but that was an omegaverse too... even though all males and females (even alphas and betas) could get pregnant. So, yeah. I need to read some more mpreg manga I guess. This concept (outside the omegaverse) is still too fresh for me.
I feel like a newbie :D
Ch. 10 - 11 SPOILERS
How can someone be a MALE human but a FEMALE werewolf at the same time? The only thing, that makes sense to me, would be that he's an OMEGA (from the yaoi world). Also why isn't his sister a werewolf too?
