Luffy's Biological Mom

Long before becoming the man the world fears, Crocodile was someone else. Someone who lived a different life, made different choices, and carried something far more human. Crocodile was born a woman, and at some point in that past, through circumstances buried under years of silence, Crocodile gave birth to Luffy. And then... everything changed. Through the power of Emporio Ivankov, Crocodile altered his body and identity, severing ties with that former life completely. The reasons are his own.

Yeah, I know Crocodile is likely not Luffy's actual bio mom, but here he is.
