And two whenever Ichigo was in a battle and he was losing to his darkness aka Hollow kept trying to possess him unlike the Vizards who could just access their powers after supposedly conquering them since we never really see it. Also add to the fact that since the Vizards themselves saw Ichigo as one them they believed that his hollow powers allowed him to access the power of the mask giving abilities such as the spiritual pressure, the cero, and possibly Sonido, but with Ichigo he was able to fully access the power of his hollow side because of the fact that Zangetsu was amplifying his hollow powers and to prove this when Ichigo was learning Mugetsu from Zangetsu how was Tenza Zangetsu able to just fuse with him so easily if they hadn't already had such partnership in first place. Which means that his hollow side bonded with Ichigo to such an extent he became the physical embodiment of his darkness his darker half which meant that Zangetsu must have the ability to bring out and strengthen the darkness of its user also with Mugetsu itself robbing all light in the vicinity of its attack how is that not an ability of darkness.
