Well, since he's apparently defeated the combo of his Zanpakuto and Hollow Ichigo, I'm assuming he's mastered their powers.

About the Cero, Shinji could use one with just his Hollow Mask. So I'm guessing that Ichigo will eventually learn to fire one heck on a Cero (we got a taste against Ulquiorra) unless he's already learnt to fire one.

Which reminds me, will Ichigo's Hollow Mask remain the same?
