Actually i'm kinda scared about Quincy army considering how major characters are getting powerups. . ichigo got dual sword and two zangetsu's . .zaraki, probably renji, byakuya, komamura and others too might receive some major upgrades damn. .
This arc got make every bleach fan wet their pants. . WHEN THE HELL ANIME GONNA COME BACK
Lol really the only people who were at the level to fight the Quincy were the following... though I'm sure there are a few who'd be able to fight on par had they had their Bankai:
1. Yammamoto
2. Unohana
3. Urahara
4. Shunsui
5. Jushiro (pending condition)
6. Isshin (probably)
Those who could fight ok despite lacking bankai
1. Kenpachi (was clearly seen killing some of the low leves... with a Shikai he'll undoubtedly be on par with the upper Letters)
2. Byakuya (was capable of cutting As Nodt before his bankai)
3. Ichigo (an exception since his bankai was immune... he could survive Juha Bach's stab, but the very highest tier was still too much: Hachwald)
4. Mayuri (he's always using science and schemes. I'm sure he'd have a clever attack method. But he was also noted to be smart enough NOT to use his bankai).
My guess is that the people who went to the King's Palace will hold newfound extreme power.
Kenpachi and Byakuya will be about even to continue their rivalry. Ichigo will be able to fight Hachwald, but need a little more for Juha Bach.
I could see Rukia using a bankai.
Orihime may have some sort of new offensive move.
Chad will be punching things like a G.
Uryuu seems to have become rather OP (he's next in line to rule after all).
Kommomura may have learned a new power from his ancestors (possibly a larger size to match his bankai?!)
Obviously some lieutenants have learned bankai (Hisagi).
I'm not sure how I'm going to feel about the sudden power boosts... I guess partially because I feel Unohana and Yammamoto (if Unohana really is dead) should be rolling in their graves at how badly they got trolled.
1. Rediculously killed... Yamamoto not even putting up a fight against Bach, Unohana killed purely for plot and a power up
2. Suddenly everyone around them is being power fed... you'd think the Soul King would take up those two and give them greater power to better protect the Soul Society.
But I'm really excited to see how things go!!!! This arc for the most part has been fantastic.
