Zoro's Backstory: ?

Following the similarities or pattern between the father of Luffy and Sanji, it is safe to assume that the personality, attitude and fighting style of the monster trio are related to their biological father even though they didn’t grow up by their father's sides. They grew up, learned and developed their fighting style in different places with different inspiration, but I think blood is blood, no matter how much you try to run away from it, you'll still do things that your father would do, as we've seen with ACE during marineford arc.

Now the idea is, seeing as how Oda only wants members for the straw hats if their backstory is really messed up and had to escape some tragedy or whatnot. For Zoro I believe it is the same only that Zoro's father must of wanted to pursue his dreams, and believed a SON would slow him down, and not only that, I believe Zoro's father seen him as a weak son thus the reason for him choosing the place to drop Zoro with that swordsman, also where Zoro met Kunia. To make him into a better man etc.

I believe Zoro's father, like Luffy's father, and Sanji's father is a man well known, dangerous, strong, etc..

1. Now I want to hear who do you think Zoro's father would be

2. What kind of influence would he have in the world of OP

3. What type of person would he be

4. Like all fathers who've left their son(Luffy, Sanji) etc, why would he do it?
