I vaguely remembered a post that touched on this. It took a little digging, but I found it.
It's useful as a brief FAQ for some of the characters.

Nothing is set in stone, but in general, this is what people coming to Fiction Branches expect in the characters. If you want to break free from this, feel free to do so, but it may confuse a few readers if you drastically change some of the more common characters like Sarah, Biff, Zoe and Mikey.
