Does anybody have any theories about ichigos Hollowifcation like if it was set up and so forth cuase i've heard thing and just wandering if anybody has any good reasons
he was alwas there since ichigo is a pure soul reaper it just took something like turning into a hollow to wake him up
If your refering to the part where in the beginning, Ichigo got his powers and was part hollow at the time hence the hollow mask, then no, Ichigo became a visard without any help from Kisuke o anyone.
There "is" no theory to be detto since ichigo on his own was able to gain control over his inner hollow.and regarding your domanda whether it was a set up,then no,hollowfication was an experiment that aizen had first created back in soul society when he was still a vice captain serving under captain shinji.but as te can see aizen was surprised and intrigued to see that ichigo had hollow powers when he had originally thought that only the people he conducted the experiments on were to become a hollow type soul reaper(vaizards).
ichigo isnt a vizard because he has a full hollow inside of him the other vizards not so much. if te watched the episode when ichigo was training to get his soul reaper powers back te will see how he became a hollow. also if te read the manga te can see his resurrection form so hes kind of an espada cuz he is way stronger than some stupid viazard
