Youre absolutely right, theres still a bunch to fight.
-Zaraki / Ichigo vs Haschwald : This would be epic, and I would look forward to it. Mostly cause Im interested in seeing both Zaraki n Haschwald fight. But itll probably be along the lines of Ichigo letting Zaraki to Haschwald while he goes for the big bad himself.
-Ichigo vs Bach/Ywach : This one is definitely coming, and I really hope its good. His fight with Aizen was cool and all, but felt short for me. And was like "hah, I pwn you" with Aizen being .. well.. ROFLpwned, and in the end didnt kill him, and Urahara did the job (thanks to Ichi ofc) So I hope this one is more of a brutal battle, where none obviously have an advantage. Yknow, like both are equal.
-Kurotsuchi fight: While not so many like him, I do find him quite awesome, he inflicted the most painful death ever. To Szayel Aporro xD so I hope he does use something crafty, like a mix between his zanpakutou powers and his scientific expertise.
-Soi Fon vs Helmet dude: Yeah... not feeling it.. she will have to rely on Shunko, cause she cant go nuke anymore. In fact I want to know how will she even fight against her bankai, well I guess she has advantage since bankai is slow and shunko is fast.
-Rukia vs Unknown: Yeah sadly Rukia doesnt have much in her favour, heck even when Ikkaku, Zaraki, Byakuya, Toshiro and gang appeared for their "big debut" when helping Ichigo with the Fullbringers, she lost basically. But yeah there must be a reason why she went to the Palace, she might learn Bankai, wich would be awesome.
-Toshiro vs Claw quincy: Your idea is actually fantastic, if they somehow recover Halibel (Grimmjow, Urahara n gang? ) itd be nice to see them together. Although if Rukia does gain bankai, and Toshiro somehow recovers his, wouldnt it be fantastic to see an ice / snow duo? xD
-Komamura : Just what I was thinking. He better gain those ancient secrets and become huge like grandpa (XD ) if he wants to counter Kokujo Tengen Myou-oh
-Kyoryaku/Ukitake : Will probably face the same dude, he seems to be one of the oldest members, (Like Kyoryaku / Ukitake) I reaallly hope to see a great fight here, to be honest, even if Starrk was no. 1 , he didnt seem like so, and the fight was kinda dissappointing, I did like Kyoryakus "games" but I hope we see him go serious.
-Grimmjow vs ??? : Definitely looking forward to this! Maybe he even acquired a "segunda etapa".
Theres gonna be enough I hope, if not Kubo will make more pop up xDD I wonder about Kira btw. Is he really dead? and if so, why isnt it mentioned? (probably cause everyone was at Yama-Jis funeral, and kira was *forever alone* ) xD Im guessing hes alive and being treated.
