Gillian (最下大虚 (ギリアン), girian; Japanese for "Lowest Great Hollow"), also called Menos Grande (大虚 (メノスグランデ), menosu gurande; Spanish for "Less Big" or "Big Minus", Japanese for "Great Hollow") are the first stage of Menos. Considered foot soldiers by human standards due to their vast numbers, a Gillian is created from the merging of numerous Hollows during a cannibalistic feeding frenzy. If one component Hollow becomes the dominant persona of a Gillian, it can feed on other Gillians to evolve into an Adjuchas and potentially a Vasto Lorde if it consumes enough souls. While Gillians commonly attack in a group, one is powerful enough to be a challenge for a Lieutenant of the Gotei 13. Gillians typically arrive in the Human World through the use of spatial distortions called Kūmon (空門, lit. "Air Gate").

- Cero (虚閃 (セロ), Sero; Spanish for "Zero", Japanese for "Hollow Flash", Doom Blast in the Viz translation"): An attack used by Menos, Arrancar, and Visored.
- Kūmon (空門, Air Gate): Hollows and Arrancar can use special spiritual pathways to travel between Hueco Mundo and the other realms. These are called Garganta. A Menos Grande can open a Garganta by tearing through the barriers between the realms, thus creating a spacial distortion which opens a pathway. Gillians typically use this method to travel to the Human World.
- Negación (反膜 (ネガシオン), Negashion; Spanish for "Negation", Japanese for "Counter-Membrane") is the beam used by Hollows to rescue their comrades. Only the Gillian-class Menos have demonstrated the ability to use Negación.
