I never had to study any details of the pregnancy process, so I have zero idea about the mentioned physiology. If so, it does explain why Yonji is significantly weaker than Ichiji, Niji, and Sanji.
I want to see Sanji legitimately taking on the execs of enemy crews, and it looks like both Germa 66 technology aspects (the Raid Suit and genetic modification) will be necessary. So it would be a nice twist if Queen's weapon ends up benefiting the crew in the end. Chopper might have stopped any deaths and it would be kinda funny that Sanji is the one in a million that doesn't have a negative effect, but a positive one from Ice Demon.
Thanks for sharing!
