All-Black's history is presumably similar to its Earth-616counterpart's. It presumably was created and used by Knull before falling into the hands of Gorr the God Butcher. He fought Power Princess and two younger and older versions of her as he tried to wipe out all gods with his Godbomb. When Gorr tried to use All-Black on the present Zarda, All-Black unexpectedly abandoned Gorr and bonded with her instead, giving her the power to defeat Gorr. What became of All-Black afterward is unrevealed.
