Snake in Sheeps Clothing

This Sakura Haruno is Orochimaru's adopted daughter. She was taken in by Orochimaru when he found her in the Hidden Leafe Village orphanage and felt a special, unique power inside of her. She could see some similarities to Tsunade, so having a medical-nin on his side would be excellent for the future. Hence, he gives her a curse mark as a child and molds her not to be his next host but rather his successor and daughter, whom he was proud to call her.
