[@Taka] I will say, if you're having trouble with a second character, maybe immediately jumping into a second character isn't the best idea. I have several idea's for a second character (At this point, i think Red Tornado is probably going to be my second, most likely because i don't think anyone else has any idea's for her) but I think it's best to get a few posts in before actually seriously attempting to take on a second. I find that, after a number of posts and once you have the idea of how the character thinks, feels and reacts, eventually, interactions just write themselves.

I just think you'll have an easier time of it by getting the ball rolling on one, then using that inertia to get the second one going, rather than trying to launch 2 at the same time. Who knows, in getting Ghost Rider moving, you may find a story that actually fits a lot better.
