@limitlesssigil: obito can continously phase for 5 minutes yea but Aizen doesn't have an attack that exceed said 5 minutes, so his time limit is no problem when he can reset anytime he wants.
iirc Obito has no feats of being able to immediately use Kamui again after 5 minutes of usage.
@TheEmperor95 Obito was never winning with kamui bfr if you read my initial post you'd know that. Aizen is physically stronger yea but so are the other characters obito phased but strength doesn't help against an intangible being. I don't like arguing about speed so I tend to overlook speed difference when i believe said characters are in the same tier, I just usually assume they are fast enough to fight and react to each other accordingly. Eitherway Aizen isn't hitting obito.
