Yo, just a few disparities I noted on Shinzui's page (gotta scout out my Shichibukai opposition). Feel free to just ignore me. These are just some things I thought you might have missed and would fix if noticed.
Shinzui's age of 34 doesn't seem to match his experience as he was a top member of the Redbeard Pirates, a big crew before the Great Pirate Era which started 22 years ago. That would mean that Shinzui was 12 years old at the start of the Great Pirate Era and I doubt a top member of the Redbeard Pirates would be that young (would have to be even younger to have been a member during their prime).
Adding on to that, you should add Shinzui's birthdate (make sure to fix first) and Shichibukai installment date to the World Timeline.
50,000 seems a bit low for someone of Shinzui's status. Don't forget to get a higher bounty for him based on his accomplishments (of which there seem to be a lot) and to strike all of them through to indicate that his bounty has been suspended due to his Shichibukai status.
Thanks for your time and I hope to join you as a Shichibukai soon!
The crew Member thing ? Sorry, there is no automatic way to do it, you would have to copy the code from other page which have it and then play around with it until you are able to do it for your page. Remember to use Source Editor.
