Pain is very tough, I mean he has Shirai Tensa which can take apart mountains and cities, and create a mini moon, Deva can fly, Two different Paths have soul fcuks, Preta Path can absorb energy, Animal Path can summon many giant creature, one path can shoot missiles, and all Paths share the same field of vision.
However Aizen is just in friggin god mode in bleach. I think he could deal with Pain.
You always pick the weaker character and do no research on the stronger one. You picked Ed over Naruto and Pain over Aizen. You admitted in the Aizen vs Superman thread that you knew no feats about Aizen just like you said you only watched 1 episode of Naruto and picked Ed over him even though that is almost as big a stomp as this battle. Aizen>>>>>>>>>>any naruto character and any current bleach character even Pain.
Aizen was in like a 12 vs 1 against people who move so fast it seems like they teleport, have the physical strength to punch people through like 6 concrete buildings in a row, can launch city destroying beam blasts and have magic swords and masks (some have magic swords AND magic masks) that make them exponentially faster and stronger than they already were, which is already faster and physically stronger than Pain imo, AND usually give them some sort of magic trickery. Even with that, Aizen manhandles them all in physical combat, uses his magic sword to make a fool out of the survivors, and then goes back manhandles like 4 captains in 3 seconds of fighting. And this all happens without him even dirtying his clothes.
Plus, this is one of the few times where you can honestly say "speed blitz" and find examples in the manga/anime of the character actually fighting that way. Aizen starts off fights with one-hit KO style attacks, his magic sword or 90s level kido.
Also, wouldn't the shared vision of Pain's bodies mean that trapping one of them in an illusion traps all of them? Even without that though, I give it to Aizen.
@sickVisionz: Dang, excellent analysis. I couldn't have said it any better. But yes Aizen wins. He beat 7 captains simultaneously without a scratch, people who would make most kages in naruto look weak, then proceeded to beat 3 more exceedingly powerful captains one of which is considered the fastest person in the bleach verse and one of which is considered to be the smartest in the world. He also took out a few vice captains with even greater ease as in a single slash. Pain, who is slower and less durable than any of the characters Aizen fought would be annihilated instantly.
