Okay so I didnt actually knew what to write in this story I only had a inspiration of 1 battle and wanted to write about it and that was when Thanos arrives on earth then I was thinking of flash using his ability to open portal of multiple earth/universes to aide and then many portals will open with cool entrances of COD team(ghost, price soap,etc), DC people, Deadpool ,zoro, some anime characters ,and all,
And then travel to different worlds mabye
This was the storyline I wanted and I am quiting this novel If anyone wants to take this Idea to create a fanfic then you can.
