Desechar

Desechar (強断片心 (デセチャ), desekā; Spanish for "Cast Away"; Japanese for "Strength of a Fragmented Heart") is a form of power granted to and used by when their heart is transformed into the white masks they wear.

Overview
Desechar is an expression of a Hollow's heart. They are the trademark of Básillian-level Hollows, though their importance becomes less pronounced across the evolutionary stages. Hollows created through unnatural means are also known to lack access to their very own Desechar. Though it may change through the process, Desechar is also known to serve as the embodiment of an 's power.

These powers can be considered the counterpart to a Shinigami's Zanpakutō or a 's ; they are unique to each individual Hollow and reflect their personality or past in some form. Desechar actually have names, and as words have power in the Spiritual realms, they can be used to afford a Hollow a greater strength to their abilities. These names are initially unknown to a Hollow but are engraved within their subconscious, realizing this name takes great effort to be drawn from the depths of their mind, becoming more and more difficult as a Hollow's natural instincts pull them towards madness. If learned, the name does not need to be uttered, the knowledge of the name itself granting the Hollow's ability more power at all times.

This power can grow and change as a Hollow evolves, gaining new attributes and variations in the process, though it can never stray from the formed source of that power. A Hollow that spews flame from its mouth will not suddenly gain access to power over water but might gain the ability to manifest fire outside of its body.

Gillian-class Hollows, due to lacking a sense of self as the great many minds within it fight for dominance of the body, naturally suppress this power. Even when a single mind gains control, the Desechar remains unusable, though it returns to them upon transformation into an Adjuchas.
