My DC Comics Civil War Lineup
Everyone here is probably aware of the infamous Marvel Civil War event that Marvel Comics published several years ago. The Marvel Civil War is a controversial subject among fans, but nevertheless, many write about what it would be like if DC had a Civil War. While the people of the Marvel Universe do trust their heroes (well, most of their heroes...), but the people of the DC Universe tend to be even more trusting of their heroes. But that does not mean a Registration Act is out of the question. If a series of events were to ultimately lead up to the DC Civil War in a similar fashion to the Marvel Civil War, the Government would most certainly have a Superhuman Registration Act.
This list includes all the heroes and villains I think would go Pro Registration, Anti Registration, and Neutral.
** NOTE: All these characters are their Pre-Flashpoint incarnations.
