[@Crow] I was considering magical girl-y things, but I've got a few other ideas, if there's concern of overlap.  This really isn't the place for me to go full Nanoha, chances are.

I'll definitely keep an eye on things and see what comes to me.  I do have a question about things, though.  We're definitely starting more at the "street" sort of level, it seems like, but are there plans to end up at higher levels of character power/influence?  Sort of going up to Justice League and dealing with cosmic threats and other such things some of the time.  Though, that might be too long-term to worry about, anyway.  

I do have some general character ideas more on the cyborg/technology powers side of things, and might need to figure out just how much ridiculous scientific progress is likely to end up acceptable.  

And on antagonists, one fun thing a tabletop superhero game ended up doing is sort of every player had one bad guy associated with their character that they cooked up, and one that someone else did, which was a pretty fun little exercise.
