There is a new admiral in town and we have yet to see them. There are quite a few theories out there and I just want to give my 2 cents because you guys obviously care what I think and I am the single most important person on the world. Besides Nova *bows to Nova*
One of the main theories about Green Bull is that its not a him its a her. While I would really like to see this and I think it would be cool, i doubt Oda will go in this direction because he doesn't really do strong female characters very often. So i'm more inclined to think she's actually a he. Yes I did just assume green bull's gender. Suck it up.
Another thing I have heard a lot is that Green Bull will turn up in Wano. Not as in get high (though not ruling Kizaru). The reason why I don't think this will happen is because Wano is a 'closed' country. The navy has no power there and considering the cast of characters already involved it would seem even more bloated if the marines showed up randomly and started doing there thing.
The next one is that Green Bull will be like Akainu in his justice compass. I don't think that he is gonna be like Akainu because he was also 'forced' into the marines like Fuji and that could mean that he has the same ideals as him. Also I don't think the warlords would get abolished if there weren't more supporters.
Last but not least! Yeah that was actually it.... I don't know any other prevailing theories. Anyway what do guys think about Green Bull? Any of your own theories?
