So the same thing could be said with like Mewtwo she won't have kids either
Forgive me if I'm a bit confused, either you mean Newtwo?? Or your talking about Gwen, saying that like Mewtwo, she won't be able to have kids either?? Sorry, you're ask is worded in a way where I can't tell which one you're referring to but I'm gonna go with the latter and you can correct me if I'm wrong XD
Technically yes you'd be right, Gwen isn't able to have kids, but only while she's in the relationship with Mewtwo. If she was with someone else then that would be different, cause Gwen isn't infertile like 'Two. She's physically capable of having offspring. But since she's with Mewtwo, even though she is able, Mewtwo can't...provide her with the "necessities" to have kids so to speak.
