This is Granzon's true form, transformed by the power of the God of Destruction, Serva Volkruss.
This form is achieved by strengthening the main Granzon through La Gias's alchemy and sorcery theories, and summoning and connecting the "Baryon Creation Halo" that shines on its back. Its power is immeasurable, as it is equipped with a "Degeneration Cannon" that surpasses the firepower of a "Black Hole Cluster" and has the durability to take on multiple Super Robot armies on its own.
Not only are its armaments but all of its performance has increased dramatically, giving it combat power that truly embodies the description of a unit that can withstand a thousand men. However, the disadvantage is that the pilot, Shu, is subject to the curse of the evil god due to the influence of the "Volkrus's Curse", the generators mounted on both shoulders.
For this reason, it was essentially the God of Destruction's Yorishiro, but after Shu was revived in La Gias, the system related to the rope was changed into a converter that drew out astral energy, meaning that it was able to use only that power without being bound by the curse, and the timing of its mutation was also left in Shu's hands. However, this proved to be a disaster, as for a time immediately after the Spring and Autumn War, it was once again almost absorbed by the revived Volkruss.
With the defeat of the Titans greatly weakening the astral world and spirits and the disappearance of the three evil gods, astral energy was effectively rendered unusable, but this machine can still be used without any problems.
