The Divine Undertaker
It was in the Era of Harmony, trillions of years ago, when Chaos first arrived.
To stop all existence from growing rampantly and exhausting all sustenance, the Creator of the universe took on Chaos as its body, the void as its vigor, and black holes as its jaw—a combination to create a world-ending coffin, devouring the seas and setting lands aflame, reducing all to ashes!
Later, millions of years ago, the gods waged wars against each other when the same coffin appeared out of nowhere, massacring their ranks and decimating the divine realm.
Since then, it had gone missing, but its name continued to echo throughout the universe, leaving both gods and demons in fear!
Millions of years later, a youth was buried alive and fused with the coffin where he was kept, and he became an undertaker whose name was heard throughout all worlds.
"I'm really bad at saving lives, but I'm quite good with ending them," he said quietly with a cool visage. "I possess the Coffin of the Gods, and I can send anything and anyone to their deaths: humans, worlds… or even the gods themselves!"
