Particons

The creators of the multiverse, which reside in the very center of it all, which is the Core of Creation.

Abilities as One whole Being
As everything comes from and eventually leads back to zero, Particons in their initial 0th dimensional state are the most powerful being in each of their own respective omniverse.

Primordial Particle Manipulation
The infinite dimensional multiverse all comes from the Particons, as they are sentient "God Particles". All primordial powers, magic, cosmic powers, all planes of existence, etc comes from the Particons, as they are the prime source for everything.

Complete Arsenal
As a result of everything coming from them, Particons are essentially beings that have every form of power, as well as an immunity to every form of power as well. Having the ability to manipulate everything, including higher dimensional things, makes Particons seemingly omnipotent, even intimidating the true form of Primary Dieties, who reside in the highest dimension of the omniverse.

Omniverse Manipulation
The omniverse is under the Particon's absolute control, as everything within it was created from the Particons, including the dimensional levels of existence. At any moment, they have the potential to collapse everything in existence or recreate it at whim.

0th dimensional physiology
Being 0th dimensional figures, Particons as essentially beyond infinitely small in all directions, essentially making them indestructible.

Nigh Omniscience
As the creators of everything, the Particons know and understand how everything within all of existence works, down to the conceptual level.

Abilities when Separated
Upon being separated, which only happens when Particons are at a higher dimensional existence, the Particons must immensely and intentionally drop their levels of power in order for the entire multiverse to remain balanced and not implode on itself.
