It's about Jack ming, a detective who by chance survived the destruction of his world, only to find himself in a fused universe of Marvel/DC and other universes... but this is not the end because he found that he brought all the knowledge of a universe he didn't know... follow as you witness the growth of a legend among legend. Only the MC and the unknown characters are mines, as for other known comic and movie are not mine ps: I am not an English expert so if there is anything wrong be easy on me on comments
