One Piece: Freedom's Song

So, I was writing the next chapter wich should be out in a few hours and got sidetracked thinking about future ideas.

And I thought that why not to ask my readers and maybe something really good would come out of it.

I'm uploading this "chapter" so if any of you had and wants to share any interesting devil fruit ideas.

A/N: Also, I want to break the bad news for some of you, I'm not planning to give Yasu any devil fruit. This is for ideas to make some fights more interesting and to write some interesting characters that fit in the world of One Piece

Leave your thoughts in the comments and thank you all a lot for bearing with me

PD: I guess this chapter can also be a sort of Q&a where you leave any question and I try to answer
