Cero Master: This is only for Arrancar. The ones with the mastery over Cero can fire off 5 Cero using less-reiatsu and with no cool down. Not only that, while in the past it has been shown that it takes a bit of time to fire off a cero, they can fire it immediately even in close-range without warning whatsoever.
Shunpo/Sonido/Hirenkyaku Expert: The ones with the expertise of this are the only ones beside the ones with the mastery of assassin who can follow shunpo/sonido/hirenkyaku with their eyes. They are also capable of the after-image technique, but can only make one tangible after image.
Enhanced Reflexes: The person that has Enhanced Reflexes can hear slight changes, see differences, and even sense the air pressure change. For example, they can quickly get out of the way if they are about to be cut by a blade sensed by the air pressure from the slash of the blade.
