Mayuri should be a war potentiel IMO , the guy might create something that counters quincy main tricks (especially stealing bankaiz) .
Urahara is not a war potentiel because the king either has a lot of data that he knows urahara will not interfere (exept helping ichigo power up , and ichigo is included already in w.p.) or he really doesnt know much about the guy.
You missed my point completely. My point was that only people who vandereich knows about can be war potentials. That person can be a bigger deal than the second coming however if vandereich does not actually know about his existence and powers then he can't be a war potential. It would be plain illogical for him to be qualified as a war potential if vandereich did not actually know about him.
Its precisely the way he talked to yamamoto that seems weird. We know for a fact that there have been 2 quincy wars so far, the one 1000 years ago and 200 years ago. Does this mean that juhabach was involved in the one 200 years ago? Yamamoto and juha hadn't seen each other in 1000 years, not 200. There has been no mention of any vandereich, specialy juha, having participated in the past war and the very techniques which they use are completely different. Yamamoto was familiar with blutz based on his current fight however it does not seem like ishida's brand of quincy are familiar with the technique. More so, the letz stilt concept was dropped 200 years ago and yet shinigami thought quincy still used the form. I would think the more logical explanation is that the quincy from 200 years ago were not vandereich at all (vandereich does not reside in the human world, ishida's brand of quincy did).
If Yamamoto was right and the war potentials are the five people of whom they can't steal the Bankai; they should be at least Ichigo, Yamamoto, Kenpachi. That keeps Urahara, Aizen and Unohana as candidates for that last two places. All three of them have very much elusive bankai's.
Unohana can be a candidate but I'm betting more on Shunsui only because of that fight with Starrk where Ukitake told him not to show his bankai with everyone around (or something like that). I wouldn't be surprised if Ukitake is about the only person to have ever seen it.
As for Urahara i still doubt he's one. I think if he was Quilge would have sent that in the message about Ichigo being in HM or at least referenced it.
I'm guessing Urahara would also be a candidate ( remembering what he told to Chad that his Bankai is not suited for training ),but also I would seriously consider Yoruichi one of the 5 war potentials,mainly because she doesn't have a Zanpakutou,has VERY strong hand-to-hand combat and kido and she can also use those anti-hierror pieces that Urahara made and she also has Shunko; if she has a Shikai and Bankai,she'd get insanely strong,thus why I consider her one of the 5 war potentials.
I heard that according to Tite Kubo...
1. Captain Unohana WILL BE FIGHTING AT THE FRONT for the first time in this arc! And the full extent of her zanpakuto's abilities WILL BE EXPLAINED IN MOST EXPLICIT MANNER!
2. Tite said he doesn't know when it will be, but Captain Kyoraku WILL SHOW HIS BANKAI!
3. Tite hopes to return Grimmjow later, as well as considering Aizen's return.
Now for the remaining 3 war potentials...
3. Uryu Ishida; I am thinking that because of the conversation took place between Kirge and Ichigo...
Kirge: "you mean to say Ishida Uryu's Heilig Pfeil is weaker than mine? Weird... IT SHOULDN'T BE. Now I have even more new reports to submit to his majesty..." (Uryu should've been stronger than he actually is but something must've happened to him in the past that made him weaker) Besides, being a Quincy, Ishida could be a big help.
4. could be ANYONE's guess... But what do you think of Tessai Tsukabishi (former captain of Kido corps and a Kido master, even more so than Hinamori)? This could be his chance to display how destructively powerful kidos can be.
5. I am split between Yamamoto (in recent chapters, I was like, WOW... JUST WOW...) and Aizen.
I wonder if the Quincy actually considered Yama to be a War Potential? They didn't seem concerned about facing him, nor about stealing his Bankai, nor did they mention anything about him when they were talking about Kenpachi. If Yama was one, they probably would've mentioned it... Yama was right there.
Yama is damn strong, but I'm not sure that's what makes the list. It looks like they underestimated him.
