You lingered in the living world for too long without finding peace or moving on to the Soul Society after death, becoming susceptible to negative emotions, regrets, and despair. These negative emotions eventually consumed your soul, eroding your humanity and turning you into a hollow. Hollows are powerful and malevolent spirits that have lost their hearts and transformed into monstrous creature driven by an insatiable hunger for souls. Hollows possess a wide range of grotesque and nightmarish forms, often combining animalistic features with a humanoid shape. Their distinct masks serve as both a defining characteristic and a source of power. These masks symbolize their shattered identities and human pasts.
As a hollow you possess formidable spiritual energy, granting you immense strength, speed, and regenerative abilities. You are a relentless predator, attacking with razor-sharp claws, powerful bites, and energy blasts known as "Cero" and are capable of opening gateways to other dimensions known as Garganta. Unlike other hollows you never lost your sapience and is directly born as an Adjuchas. Moreover, unlike normal hollows you do not need to continuously devour souls to prevent yourself from regressing back to Gillian. However, you still need to consume sufficient number of souls to evolve into Vasto Lorde.
(You can customize your special ability that you receive as Adjuchas.)
