A lot of folks, when crafting the instantiation of a new idea, get all wrapped around the wheel "proving" to themselves -- if to no one else -- that the idea in question was, in the words of Daffy Duck, "Mine, mine, all MINE!"
"I don't. " (In the words of "Doc" Holliday)
This little fictional project is creative. It comes out of our brains and the entire history of words written in English (at least), and from every story you've ever heard.
What follows is a list of known friends, precursors, fellow-travelers, what will you. For each of these, it is possible to point out what's different. I'm not going to do that in all cases, although I may do so for a few- I think it's a waste of energy. I suggest others don't either. OK, maybe in the abstract. But don't argue the details. It just ends up looking petty.
Feel free to add to the list, or critique the entries on it.
In Alpha Order, ascending (when I get around to ordering them)
- Henderson, Zenna, The People stories
- "Heroes" (NBC TV show)
- Intimations of Immortality (book series by Piers Anthony)
- The Watchmen, graphic novel by Alan Moore
- Daredevil comic books (originally developed by Stan Lee, Bill Everett and Jack Kirby)
- Stephen King, Firestarter and other works
- Dracula, Frankenstein, Dorian Gray, Sherlock Holmes, Springheeled Jack, and other 19th century characters with unusual but not fully superhuman abilities.*
- The Martian Chronicles, by Ray Bradbury
- Xanth (fictional world created by Piers Anthony)
- "Are you a mutant?" quiz (promo site for first X-Men movie)
One difference is that many of these tales end up as epics- you know, large sweeping stories with world-changing events on a large-scale. The Small Powers domain is not intended to become epic, nor is it thought of as epic. It's, ummm, you know, small.
On the other hand, the expression of the idea in the words I, or you, write, that's yours alone (or mine, if I write them; you get the idea).
*I am beginning to wonder is "paranormal" is a better referent term than "preternatural" for these characters and their tales. That would bring in The Twilight Zone (and Night Gallery) and others, I suppose. What do you think?
