Multi-Headed Gillian

The Multi-Headed Gillian is an old project of Sosuke Aizen that was used to see if he could create a Vasto-Lorde by combining Menos Grande together. This of course failed and the project was abandoned. It was later found by Hontomaru and used for his plots in the Dangai.

Appearance
The Multi-Headed Gillian is giant in comparison to other Hollows, dwarfing even the largest standard Hollows by at least the size of a two-story building, but lacks agility and intelligence. Each of it's eight heads also have long tongues capable of breaking a fellow hollow's mask. Each of it's heads also have it's own mask.

It seems to be covered in some form of armor with it's hollow hole at the middle. This armor goes all the way up it's tail and forms off as an axe like appendage. It has no legs and seemingly no arms, it simply appears like a giant snake.

Powers and Abilities
High-Speed Regeneration: Despite having great attack power and speed, like any Gillian, it's greatest strength is it's regenerative power which is multiplied by eight, one for each head. This is displayed in how it can regenerate one of it's heads if one is lost. It can quickly regenerate any part of his body except for it's brain and internal organs. However, this power also requires that it has sufficient spiritual energy.

Immense Spiritual Power: Their already vast spiritual power as a Gillian is significantly increased furthermore after they all became one massive Menos Grande. Even being within the vicinity of it's release instills despair on those who can sense it. Mokin Kurushimi, a Captain-level shinigami who is an expert at sensing reiatsu, noted that the density of it's spiritual power was so vast that it could hardly be identified as a Gillian-class Menos.

Cero: Like many high-classed Hollows, the Multi-Headed Gillian are able to fire Ceros. Unlike most Hollows, their Cero is composed entirely of electricity and of fire. They can also fire regular cero, though this is very rare. It is fired from between the tips of it's different mask horns instead of it's mouth as it was in the Gillians when they were separate. Their normal Cero is crimson.
