God (Midnightverse)

"You're frustrated. I get it. Believe me, I was hands-on – Real hands-on for, wow, ages... I was so sure if I kept stepping in, teaching, punishing, that these beautiful creatures that I created... would grow up. But it only stayed the same. And I saw that I needed to step away and let my babies find their way. Being over involved is no longer parenting... It's enabling."

- God to Issei and Irina

God, also known as Yahweh, Elohim, and Allah, is an immensely ancient and powerful Primordial Being. He is known as the Creator and is responsible for the Creation of the entire omniverse. God is also the father and creator of the Angels and Fallen Angels as well as the creator of Sacred Gear. After the Great War, God was presumed dead after sealing away Trihexa but in reality, he entered a deep sleep for 300 years. After waking up, God sat on the sidelines watching events unfold.

After the release of Tathamet, God came off the sidelines and confronted his sister. After an apocalyptic battle, God was severely injured by his sister. As all Creation around them died, God was eventually healed by his sister and the two left the Earth to explore Creation. Currently, God and his sister are in a universe pretending to be survivors in a post-apocalyptic zombie universe.

History
Before the Beginning, Nothingness was all that existed and was existence. At some point in time, God came into being marking the start of Existence itself. To show that there could be more than just the two of them, God began to craft worlds and present it to His sister. She, in turn, destroyed them thus marking a cycle. From their interplay of Creation and Destruction was born Life and Death, who embodied the very concepts themselves. After some time, God birthed the Seven Archangels from his very essence. From there, He began to craft one last world to show His sister. The Darkness destroyed that world. Having had enough, God engaged The Darkness in a long terrible war in which an infinite number of realities were created and destroyed in an instant. After a long war, God sealed His sister away locking her behind a Mark bore by His eldest son, Helel for all time.

God went on to create all of what would be later referred to as Creation, the collective term for all realms. As He created, The Outer Gods came into being representing the Concept they embodied or were. God created the Soul from which his younger sister, Life, created the first life forms and which He used to create the First Beasts, the Leviathans. Seeing the Leviathans devouring everything, God sent Michael and Lucifer to lock them away in a prison realm known as Purgatory. Billions of years after everything began, God guided the evolution of beings that would later be known as Humans, The First Two Original Humans were named Adam and Eve. God blessed His two youngest children with agelessness and immortality so long as they never ate the Fruit of the Divine Tree at the center of the Garden of Eden. God appeared before all the Angels and Archangels and proclaimed Humanity His greatest creation and asked them to guide them. His son, Lucifer, was overcome by jealousy and tempted Eve to eat the Fruit of the Divine Tree. Heartbroken, God banished Lucifer to Earth to learn his lesson and cast Adam and Eve from the Garden and returned it to Heaven.

Hundreds of thousands of years after Adam and Eve, God grew displeased with Humanity for the atrocities they committed. He resolved to wipe them all away until He saw the family of Noah. Appearing to Noah in the guise of an elderly man, God warned him that He was going to cleanse the Earth in a torrential flood and that if he wanted to live, he had to build an Ark massive enough to fit two animals of each species and his family. After seeing Noah finished it, God sent a massive flood to wipe all manner of creatures from the Earth.
