At most, ulquiorra is stronger than halibel after his level 2 resurreccion. But now way he is stronger than baragan or stark. So yea I'm pretty certain that the senior captains could handle ulquiorra well.
I also cannot believe that genryusai is actually being compared to ulquiorra after we have seen him wreck havoc without his zanpakuto and also still having enough strength to cast a high level kidou after getting hit by an explosion which is far greater than anything ulquiorra could have produced with his powers.
I'm not underestimating ulquiorra here but I cannot even imagine him being able to breeze through hitsugaya's latest hax-mode bankai form (the one where he summons a massive blizzard over the whole battlefield and freezes everything instantly).
ok i guess theres doubt over the old geezer and strawhat but the lower captains liek hitsuguya shoudlnt even be talked about , hitsuguya of all people against ulquiorra are you kidding me hes no match for ulquiorras second release , his speed alone wil defeat hitsuguya,
The greatest trick the devil ever pulled was convincing the world he never existed
Give a man a fish you feed him for a day
Teach a man to fish you feed him for life
well yamamoto would kill him in a sec,kyoraku would definitely defeat him the same goes for ukitake i think and for soi fon.dont know about byakuya maybe.i dont think kenpachi could defeat him
well since no one has seen him in his 2ED form its possible that he was under rated and should have been higher up on the food chain and yeah i think more than a few of them could have taken him down for sure
