White is capable of infecting whomever it bites with a poison that induces Hollowfication. In any process, the main determination of having achieved Hollowfication is the manifestation of a Hollow mask.Ī creation of Sōsuke Aizen formed from the souls of many Shinigami. The process by which to activate such a transformation can be achieved by three possible methods, though only two are known in any real detail. When Ichigo's Hollow powers started to increasingly manifest while not under his control, Shinji explains Ichigo's conflict with his inner Hollow is a common symptom other Visored had to deal with at one point or another in order to master their abilities. It manifests itself as a unique mask of different shapes and designs. Only those who have control over their inner Hollow can Hollowfy. Hollow-Shinigami Hybridīy gaining the strength of a Hollow, one's Reiryoku increases dramatically. Īccording to Kisuke Urahara and Mayuri Kurotsuchi's hypothesis, a Quincy is incapable of Hollowfication, as Hollow powers are essentially "poison" to them, and should a Quincy be infected, it would weaken their spiritual powers and lead to a Soul Suicide, with no chance of Hollowfication to occur. This is called "Soul Suicide" (魂魄自殺, Konpaku Jisatsu). In the end not only the boundary between souls, but also the soul itself and the external world is disrupted and the soul, regardless of its own will, self-destructs. When a soul is "Hollowfied", as the condition progresses the original soul gets mixed up with the Hollow soul, becoming a monster unable to reason. Originally this was meant to be used to strengthen a Shinigami's soul, but the technology that Soul Society possessed was not advanced enough to control it.
Hollowfication is the act of inserting a Hollow's soul into a normal soul, then breaking the boundary between them to try and turn the original soul into something more powerful. 5 Those who have undergone Hollowfication.
