The Triune God

Thus may one describe its shape: As the ocean's tumult. As the luster of a thousand polished pennies. As an great orrery, a dozen globes rotating around one another in complex combination.

Thus may one describe its nature: As the ceaseless pounding of the waves. As the eternal stability of hammered metal sheets. As the perfect turning cycle of the heavens.

The triune god. The sea, copper, and the sphere. Embodiment of stability in motion; cycles and meaning in chaos. An emblem of sanity in a world overrun by unreason.

Also, it transforms into a mecha! And fights against Maxwell's Daemon! It's sort of embarrasing, really. It levels Tokyo! But everyone does.

How does this triune god fight, you may ask. This is how! Its mecha is a sort of whirling assemblage of spheres set on copper rings, which rolls (in a completely unnecessarily complex manner) into battle. The complexity of the system makes it very hard to predict where it will strike! Maxwell's Daemon can move heat from one room to another in defiance of the Laws of Thermodynamics. This is more useful than you would think in kaiju battles, but it is still not enough to allow him to triumph over the Triune God. But it still levels Tokyo. This makes it a little remorseful.

Also, it can speak to fish!
