What i don't understand is Ichigo managed to fight Kuchiki Byakuya more or less on par when he gain his Bankai. But he had to get 'Hollowed' before he can be even on similiar power level as Espadas like Grimmjow.
Whilst later on, we see that Kuchiki Byakuya can defeat an Espada quite easily?
The 12th Division Captain, Kurotsuchi Mayuri also defeated an Espada pretty fast.
I don't if i mis-read something, or is there a difference in the power levels of captains when they are in Hueco Mundo. Sorry if this is a silly question.
