Hinamori vs. Aizen vs. Hitsuguya
I think there are two possibilities:
1. Aizen fights hitsuguya, Histuguya gets seriously hurt proctecting hinamori. Hinamori gets pissed and fights aizen. Most likely she'll lose and Ichigo or someone steps in to save her ass.
2. Aizen brainwash hinamori, and histuguya fights aizen to the death. tragic scene where hinamori wakes up and lets hitsuguya kill aizen.
conclusion: either way, some one is gonna die... -_-
I dont see the point with this topic.
At this point there is noone who can beat Aizen.
Hinamori vs. Hitsugaya would be interesting. Hinamori's shikai isn't too impressive (though it would be excellent in actual physical combat since it's a swordbreaker design) but she does have extreme dedication to push her along, can presumably achieve bankai, and maybe even be made into an arrancar/vizard. When you add in the law of Hitsugaya never actually winning and that he wouldn't be able to fight full-out against her, it would probably be a close match. This is assuming it happens at some point later, not today.
Uryuu freaky, pale and geeky,
