>>39600390Do you know anything about biology what happens when you significantly altered or foreign DNA into any womb? Its instantly attacked and destroyed. The protections against pathogens is so strong 2/3 of all fertilization end in miscarriage as the mothers body kills the egg.
That's how sensitive it is, so what do you figure would happen if you stuck an egg into Mews womb that has been significantly genetically alter? It'd be destroyed like a virus.
Mewtwo would have needed to be vat grown as just look at him, hes a fucking chimera not a Mew also the size difference would have made gestation inside of a Mew impossible unless you think mew's womb and body can stretch out like beach ball.
The line has a be throwback to before they fleshes the characters out or agreed on breeding mechanics in pokemon especially since we know now that all pokemon that breed lay eggs, Mew is pokemon there is no reason to believe it wouldn't too.
