People who have seen The Flash may know about an alternative universe. In that universe, Batman meets Barry Allen and learns about rewriting history. Later when Joker has created a havoc, he confronts her and tell her that she can re-create history if she wants to but after discovering the truth that her son will become Batman, she is horrified and falls to her death in her own house. How cool would that be if a Flashpoint storyline is shown either in The Flash or as a movie!
