FIRST, ONE PIECE SPOILER ALERT. IT'S ABOUT WHAT HAPPENS TO ACE. GAVE YOU WARNING.
After morning over Ace's death I thought of "what if he had a kid." I saw what he went though and figure he does want to have a kid. I also read a yaoi where that was his fear and why he does have sex with girls. I though of what if he did but doesn't know it. I was thinking that he hooks up with a girl for a bit and go there separate ways. She end up pregnant but says notion, one is that its ace's child and hes under arrest then, to anyone. She raise the kid till luffys crew meet up after two years and shes there know he will be. She tells him one the kids is and reveals that she was a captain of her own pirate crew but gave it up to raise him. It what I got so far with a few idea scatter everywhere else. I don't know where to start writing yet or if I can.
I just putting it out there in case some one got any advice or want to use my idea just ask so I can read it if you post it.
