The thing about Batman and all of his villains and those that help him, they age. Everyone gets old and eventually stops fighting. What will happen when the second generation villains meet and decide what the next step is? Get to know everybody and their history in this story.
The story is told from one specific child of the past. What will happen when she wants to relive the glory days of her parents just because she is bored? Will she team up with new villains or children of old villains? Will she get sidetracked by new loves? Will new heroes rise to stop her and her 'friends'? Find out.
This entire story is the effect of my imagination. I do not believe any of this is true in the DC universe, if it is it is accidental. I also do not mean to copy anyone else's ideas.
