Creating heroes and superpowers are hard. You need to create a good community around ya. Then it’s will be easy if the story can keep up with the fans.I'd wanna create a Multiverse which has the likes of a Lord of the Rings type verse (i doubt we've seen much of a LOTR type Epic Fantasy comic) / Sandman type that Neil Gaiman wrote though that would be a start. Then i'd wanna explore in creating superheroes like DC/Marvel Comics.
In a nutshell i'd wanna outdo both DC and Marvel but have those collabs with Image/Dark Horse/Fantagraphics/Boom Studios characters and even Manga.
