>>90458957On one world, or perhaps one universe. In DC comics, even God isn't top Dog. Mandrakk exists above God, outside the multiverse, and actually ate the entire multiverse, including God.
Mandrakk is a character which breaks the 4th wall and required breaking the 4th wall to beat on both occasions he was fought. He is able to devour the fiction we create(including the one your Mask of Life comes from), and was defeated by the very concept of Superman, the very idea of Super Heroism he represents, his impact on reality and the power of Narrative.
Ask everyone in your town if they know who Superman is and almost everyone will say they know him, from young to old. Ask those same people about The Mask of Life and almost none of them will have heard of it.
