From Jeriendhal, of course!
8 – Do you write OCs? And if so, what do you do to make certain they're not Mary Sues, and if not, explain your thoughts on OCs.
1) Yes, certainly. In Saint Seiya (leaving out villains) the principal ones were Erik Nygard and Danielle Arwen Lanier.
2) Um, why would I do that? Some of them ARE Mary Sues. I just try to make them GOOD Mary Sues, whose presence in the fic doesn't destroy the story. Erik Nygard is certainly ME, and he certainly gets to do a lot of Sue-stuff, but he's kept under control by considering his limitations.
3) Original characters permit the writer to explore the universe from a point of view that's their own. This can lead to terrible Mary-Sues in which all things revolve around the OC, they can do no wrong, and everyone loves them, or it can illuminate aspects of the universe that the original show or book never explored for one reason or another.
