A large organic like cannon that has been experimented on for some time now. It utilizes a newer concept in drawing energy. The thing ranges vast in size and is mounted in the middle section of Las Noches where it can be raised upon activation. It resembles a large beast who's head resembles that of a dragon. The mouth is pried open at all times and it's eyes are of the deepest of yellow, giving it a sinister look of a weapon along with it's behemoth size. There have been many battles in the old days for this weapon and it bears many scars as can be seen on it's surface. Once activated, the beast works very similar to that of a quincy by drawing in energy from the surrounding hollows in the area which every weaker hollow below adjuchas rank in one large gulp. For that, the blast's nature resembles the nature of a hollow's cero except 100 times amplified. Once the cannon is fully charged it will then fire off towards the target pointed at and cause extremely powerful damage. Once fully charged, the power can be toned down into a nuclear like state giving the activator the ability to nuke down areas in Hueco Mundo in one shot, however it isn't as powerful as their kido cannon to where it literally destroys dimensions. Targets aimed at such as adjuchas and arrancar are completely erradicated upon impact should they get caught in the blast and it's absolutely unavoidable unless evacuation is preplanned.

~Update~

-The Cero Cannon isn't ready until everything is done with the quincy the privaron are working on.
