The title is self explanatory. You have to put yourself in one of the One Piece character's shoes and tell me about a situation where you would have done something different from what the character did in the Manga.
If I were in Mr.3 shoes when he was on the execution platform with ace and Sengoku, I would have acted sooner and made a wax key to release Ace.
Or It can be a fun change that you think would have been funny like For example ....
If I were in Kuma's shoes when he was sending all SH flying to different islands, I would have send Luffy to K'ama Island and Sanji to Amazon Lily for change XDXD
You you get what i am trying to show so now tell me if you would have done something if you were in shoes of any One Piece Character.
