Forest of Menos

The Forest of Menos, introduced during an anime-only filler, is an area below the surface of Hueco Mundo's desert where the average Hollow hide from the Arrancar. Gillian- and Adjuchas-class Menos dwell here, along with possibly Vasto Lorde-class Menos. The forest is filled with large trees made of a silvery quartz substance. These trees extend to the surface and dot the landscape of the desert in Hueco Mundo. Aizen and the Arrancar have a considerable amount of influence here, judging by a large group of Hollows bowing down upon seeing an Arrancar. The Adjuchas in charge of the Forest of Menos are under the command of Sōsuke Aizen.

Ashido Kanō, a Shinigami, also resides in this area after being stranded during an assault on some Hollows which had invaded the Soul Society. His current status after helping Ichigo and his friends escape is unknown.

In the Zanpakutō Unknown Tales arc, Muramasa appears limping through what appears to be the Forest of Menos.

Trivia

 * The Forest of Menos' original name was to be Arbolada de al Menos.
 * The Forest of Menos along with Ashido Kanō were to be in the Hueco Mundo arc of the manga, but were cut due to time constrictions.
