Originality? I could help you with that. If you're interested in doing an OT, here are some things to consider;
- Game-based, anime-based, or generic canon? Each one opens up different possibilities.
- You don't have to start at the beginning. A game-based fic I'm working on, The Sixth Warrior, begins with Kalia's defeat of Cynthia and rise to the Champion position. She already has a full team of strong Pokemon, tons of experience, and knowledge, giving me the opportunity to write intense battles without making her an overpowered Trainer.
- Your main character isn't required to dream of being a Master. Maybe they want to be a breeder? A researcher? Maybe they want to start a Gym in their hometown? Most characters in Pokemon have a final goal - be creative.
- Please, please, PLEASE make sure that the Pokemon don't become automatons. Give them personalities, or at least don't limit their appearances to battles. I'll cite from my game-based fic again; Tempest the Staraptor is motherly and caring. Mystil the Mismagius is paranoid and twitchy. Twiggy the Torterra thinks he's the hottest thing on four legs. Pokemon make wonderful characters, since their elemental affiliations can be used either to supplement their personalities (hot-headed Fire-type) or as a foil to their personalities (hyper, overly-friendly Dark-type).
- Don't use a plot from the games. Team Rocket takes over Silph Co.? Been there. Cyrus trying to destroy the world? Done that. The ulterior conflict of your story shouldn't be one that we know (or think we know) the outcome to. Same villian, different plot? (___ returns!) Different villian, same plot? (So ___ was really the one behind all of that...) Totally original villian and plot? Your choice.
- On a related note, your character doesn't have to save the world. They could save...a forest. A town. Not everyone is expected to become the greatest hero. In fact, nothing really has to be saved. In my ongoing fic My Name Is Fuega, there is no real 'villian'. Fuega struggles with herself and nature, rather than some evil Pokemon bent on destruction. True, there are antagonists, but none are any more than your standard breed of bloodthirsty ruffian twisted by the reality of a 'kill-or-be-killed' world.
- Don't neglect other characters. If you get too wrapped up in your main charrie and their exploits, you might forget the surrounding world. You know all those character-du-jour filler episodes in Pokemon? How there's always a person who appears and then is never (or rarely) seen again? Yeah. Avoid that. If you've ever read PokeSpecial, you've got a pretty good idea of how to bring back apparently insignificant characters in a way that affects the entire story.
- Plan it out. So you've got your premise and your characters. Let the idea stew for a while and make sure you know how the plot will flow; where it begins, where it ends, and what happens in the middle. Both of my main fics (My Name Is Fuega and The Sixth Warrior) fell prey to my lack of foresight; Fuega was restarted when I realized I had no idea where I was going, T6W is being rewritten right now because I decided halfway through to add more characters and plotlines. Make sure that you know what you want to write before you write it; you'll be much more satisfied with your work in the end. Trust me.
-phew- And that was only OT fics. I didn't even talk about how to handle canon characters...
Not to brag or anything, but...I'm good at originality. If you want to PM me with specific ideas and/or problems, I'd be happy to help you develop some premises for a fanfiction.
Good luck, Vance!
