Ikomikidomoe

is an special, inherited Zanpakutō forged by Ōetsu Nimaiya out of an ancient Hollow.

Appearance
In its sword form, Ikomikidomoe is pure white, almost glowing, large broadsword with black spots on it.

In its Hollow form of its second release, Ikomikidomoe is a giant, humanoid creature with a long torso and elongated arms which reach almost to the ground. Its forelimbs end in large claws, while its legs are much shorter. Ikomikidomoe does not have a discernable neck; instead its head is an extension of its body. Its forehead is covered in hexagonal markings, while a structure extends from its nose back across its cheeks, ending in large circles just beside the hexagonal markings. A long beard extends from beneath its nose.

Personality
Ikomikidomoe is quite prideful and arrogant, and is insulted when regular Shinigami even voice the possibility of being on the same level as its current wielder. Despite this, Ikomikidomoe seems to know and respect Baraggan Louisenbairn to some degree, and was mournful when it heard the other Hollow had perished.

Ikomikidomoe also appears to have misogynistic beliefs, as it instantly assumed Tier Harribel and Nelliel Tu Odelschwanck were mere "maidservants" of Baraggan's court, rather than the powerful rulers they actually are.

History
A long time ago, Ikomikidomoe was a powerful Hollow that existed during Baraggan Louisenbairn's time as ruler of Hueco Mundo.

At some point in the past, Ikomikidomoe was forged into a Zanpakutō by Ōetsu Nimaiya, who hid it away in the Hōōden. During the Wandenreich invasion of Soul Society, Tokinada Tsunayashiro stole the sword during the chaos.

Powers & Abilities
Immense Spiritual Power:

Descorrer: Ikomikidomoe can freely open Garganta for its wielder to travel through. It can do this either on command, or when it feels its wielder's life is in danger.

Zanpakutō Abilities
Due to its unique nature, Ikomikidomoe has numerous release commands that each draw out some of its power. Since Ikomikidomoe is a Zanpakutō forged from a powerful Hollow, most of Ikomikidomoe's powers are those of Hollows.


 * Orbit the stars, Ikomikidomoe!: The first release command; Ikomikidomoe transforms its blade into a massive Hollow arm that can attack on its own initiative.


 * Send them to their burials, and engrave them in memory, Ikomikidomoe!: The second release command; Ikomikidomoe transforms into a gargantuan Hollow noted to be around the size of the Espada Yammy Llargo's Resurrección or the Gillian spouting Hooleer.


 * Enhanced Roar: In this form, the mere roars of Ikomikidomoe can shake and devastate a part of the Rukongai.


 * Hollow Spawning: In this form, Ikomikidomoe can spawn numerous and varying Hollows to overwhelm opponents. These Hollows are said to resemble Adjuchas in both appearance and power.


 * Hatch the deceased, Ikomikidomoe!: The third release command; Ikomikidomoe transforms into a large, humanoid Hollow, though still smaller than its previous release. While this form resembles an Adjuchas, its power is greater than most Vasto Lorde.


 * Reiatsu Blast: In this form, Ikomikidomoe can release a massive blast of Reiatsu, strong enough to greatly injure three Espada.

Weaknesses
Conditional Wielding: Due to being a special, inherited Zanpakutō, Ikomikidomoe can only be wielded by select individuals. Specifically, only powerful hybrids such as Ichigo Kurosaki or Hikone Ubuginu can use Ikomikidomoe's power.

Appearances in Other Media
Ikomikidomoe appears in Bleach: Brave Souls during Hikone’s ultimate attack; Hikone uses Ikomikidomoe’s second release and summons its giant Hollow form, releasing a large burst of energy causing several tornadoes.
