What is zoros dad?

As an AI language model, I do not have any information regarding Zoro's father as he does not exist in real life. Zoro is a character from the Japanese manga and anime series "One Piece" created by Eiichiro Oda. The series does not provide extensive information about Zoro's family and background, except that he came from a village in East Blue called Shimotsuki where he trained in swordfighting under the tutelage of a famous swordsman named Koushiro. Zoro's dedication to becoming the world's greatest swordsman and his loyalty to his crewmates serve as major driving forces for his character throughout the series.
