An

Anu is the Supreme Being of Midnightverse and the Creator of everything that exists. He is a boundless entity that has always existed alongside his equal and opposite counterpart, Tathamet. Anu embodies Existence as opposed to Tathamet who embodies Nonexistence. It is unknown what happened to Anu but knowledge about him, if any exist at all, is scarce.

Powers/Abilities
Omnificence: Anu is responsible for the Creation of Totality itself. Every universe and multiverse within the Midnightverse, as well as all of the subgradients of Creation even the Ein Sof, are just figments of the Creator's imagination. Even the Primordial Entities, seemingly omnipotent entities who exist as boundless infinite beings wholly transcendent of all concepts of time, space infinity, and duality are presented as nothing more than infinitesimally microscopic fragments of his unfathomable self.

Trivia

 * Anu is based on Anu from the Diablo Game series much like Tathamet is based on Tathamet.
 * Anu also bears some similarities from the One-Above-All from Marvel, The Presence from DC, and Anu from The Elder Scrolls Series.
 * Anu is the name of the God-King of the Heavens and Supreme Deity of the Mesopotamian Pantheon.
 * Anu and Tathamet's relationship can be likened to that of Yin and Yang in which they are two opposing forces. Their relationship is also highly similar to Ahura Mazda and Angra Mainyu. Ahura Mazda is the Supreme Creator God of Zoroastrianism whereas Angra Mainyu is the Anti-God of Zoroastrianism with the two constantly locked in combat.
 * Anu's appearance is based on Yaha-kui zaShunina from Sekaisuru Kado.
