Batman

Ah yes, the Dark Knight, defender of Gotham City: few heroes paths are going to change as much as that of Bruce Wayne in the alterations brought about by the lack of plot armor in this version of the DC universe... For one thing, within days of the third villain escaping from Arkham Asylum, the place will be shut down and the inmates transferred to a maximum security prison! For another, Bruce will find that his costumed crusade will find him facing much tougher resistance from the Federal Government and organized crime, people who don't pull their punches or use elaborate traps, they just KILL you...

Will the Dark Knight end up in prison himself? Perhaps: but for a certainty that bat-signal business will not last very long: the FBI takes a dim view of chiefs of police in major cities that ally with known vigilantes...
