Nice admiral WU, however there are two things I think you should bear in mind.

1. I agree with Soul, creating a swordsman that is beyond Mihawk's caliber is rather unlikely.

2. If I remember correctly, we were given the names of all the Vice Admirals pre-timeskip, therefore, all of our admirals were presumably promoted to Vice Admirals and eventually to Admirals only during the timeskip or afterwards.

Even though these characters are "home-made characters" as you describe them, it still means you should keep things in proportions and adapt the character to the main storyline. Hence why you also have to find a reason why he didn't participate in the War of the Best at Marineford as all of our admirals are too powerful to have been insignificant.

Also, I'm nearly finished editing my character (a matter of minutes) so stay tuned.
