This is just a fun topic about what is the cruelest thing that you could do to a character from One Piece. For instance, here is one for Arlong:
Make Arlong eat the Human Human fruit, so that means that he is his least favorite species, AND he cant swim anymore. To add insult to that, give him braces.
Here is one for Sanji:
Make him go through permanent puberty, he has zits all on his face, and his voice cracks at every other word. Then, he is also as weak as a young teenager, before his muscles develop, so his kicks are a WHOLE lot weaker.
So, what are some of yours?
