you are a heart pirate, you used to be a donquixote pirate but once doflamingos era of terror was over,law recruited you to the team,you were doing something in the main area when you heard something,you ran in and saw your captain,but,he looked off,he now looked like a woman,bepo also looked like a woman

Law : Damnit! How did this happen....

it was definitely the work of a devil fruit user from the crews encounter with blackbeard, one of the crews members maybe had a gender changing devil fruit and hit your captain
