it's a well known fact that the Shichibukai are seven. When one of them resigns (Jimbei), dies (Moria) or goes under arrest (Crocodile) he/she is replaced for another one like Blackbeard, Law and Buggy.
So after the 2 years skip the current Shichibukai are:
- Boa Hancock
- Buggy (lol)
Who is missing?
