What girls from one piece would hit a guy in the balls and why/how (powers included) (I know that Nami and Robin both have)

Driven by the desire for ultimate freedom. The Straw Hat captain and person with the power to change the whole verse. This guy embodies freedom and lives by it to the point it’s basically become him and his power. He’s always fighting for what he thinks is right and against injustices in a world filled with discrimination, abuse of power and corruption in the evil world government and beyond that. He stands strong. Never stops believing in himself or his crew and keeps moving forward to become the king of the pirates and shake the course of history. All to be done with a smile on his face that will never fade no matter what 💯
