Are the three Gorgon sisters blood related? Boa Hancock is considered to be the most beautiful woman in the world of One Piece, but her sisters are totally different.



Are they blood related sisters? 


   Or perhaps something happened during their time as a slave?
Those 3 girls are definitely blood related. Boa Hancock explains her tragedy in episode 415 in which we can see the 3 girls in their childhood and early teen years and they definitely look similar. Their different characteristics are probably because of,


just being different:- even in real life siblings have different traits which grow as they mature.
different devil fruits:- we know that Boa Hancock ate Mero Mero No Mi fruit (Paramecia type), and her sisters ate Hebi Hebi No Mi fruits (Zoan type), Hebi Hebi No Mi, Model Anaconda (Boa Sandersonia) and Hebi Hebi No Mi, Model King Cobra (Boa Marigold).
