If Yammy was as strong as he ought to have been then Yammy.
I can't even believe someone thinks this is a good idea for a match. :P
Supes wins so easily here that isn't even funny. Even if Aizen manages to land Kyouka Suigetsu somehow, he lacks the destructive capacity to even harm Supes.
Shinigami magic swords that can obliterate environments with a single swing. Superman gets whooped by magic remember, now a shinigami such as Aizen who is immortal and moves quicker than the flash btw would roflstomp superman. Kenpachi could one shot superman. Bleach is fast becoming something more than DBZ tier have you not been reading it? Not to mention he has no defence against Aizen's reiatsu in "offence mode"...
Aizen wins using Reiatsu.
It erases humans with no spiritual energy so humans with powers and superhumans from the western comics would just take a little bit longer to evaporate assuming their non spiritual durability defences work but would ultimately disappear from existence.
Superman has no spirit energy so he can't defend himself against Reiatsu for no longer than lets say 10 minutes before he turned to nothing. It would be a ranged battle for him to stay alive, for a short while.
Face it guys, Superman's dogmeat in this match-up...
@othus12: In Bleach terms, right now the soul of Madara is known as a "Plus" or a spirit of a person who has died but failed to enter Soul Society, The only thing Aizen needs to do is a "Soul Burial" to send Madara's spirit to Soul Society. Heck, if Aizen wants to, he can kill Madara again in Soul Society and Madara's spirit will turn to basic Reishi(the "God particle" of Bleachverse.)
LMAO, yes exactly!
