I've been working on something like that. Know any artists?
I've got: main characters, secondary characters, primary origins, general scenario origins, facilities, institutions, world backhistory, primary character storylines, interwoven inter-main-character storylines, four different multi-episode antagonists, some single-episode antagonists, and a good enough handle on science across a lot of different disciplines to make most of it seem pretty plausible (with a minimum of 'because the creators SAY SO' fiat and over-expository hot air).
Also some specific ideas for character designs, scene layouts, visual sequences, book/issue/whatever layout, ability effects, and (maybe) a title.
What I don't have is the ability to draw or color.
Shit, I just need to make this a post, don't I? I have no idea how someone gets started as a writer.
