Yeah....Ichigo overuses his Main Character Power. That's why its hard to figure out Ichigo's strength level because...let's see...
1.) He beat Byakuya with only bankai and beat Kenpachi with shikai only
2.) Got his butt kicked by Nnoitra and Nooitra got beaten by Zaraki
3.) Ichigo almost lost to Yammy in bankai
4.) Byakuya beat Zommari by barely using bankai.
Wtf?!
1) He havent, Byakya amoired his defeat... could still beat him with KIDo though... Ichigo was barely standing. He havent won Zaraki, it was tie + Zaraki messed up his sword.
2) lol.. HE barely finished Grimmjow, do you think it was possible for him to beat nnoitra in this state? No way.
3) Hollow distrubed him... When hollow didnt he just cut of yammis hand..
4) loook nr 3.
I dont think Kubo is overpowering Ichigo, it's ok tho. But i agree that Ichigo shouldnt defeat Ulquiorra. And I have the same opinion as the thread starter that Ulquiorra is somehow special.
Look, he'sdoing
1) special tasks for aizen
2) repoting directly to him and giving him advices
3) getting in charge of las noches!
too much responsibility for only 4th rank!
Aizen uses 1 2 3 only to fight!
