In Injustice: Gods Among Us and other elseworlds stories, the main theme is usually Superman for whatever reason decides to stop playing nice and enforces peace. Being the Man of Steel, he typically has no trouble doing this. Batman and sometimes a small handful of other heroes take the role of the freedom fighters opposing Superman's dictatorial regime.
I find this interesting, because Batman is typically the person with the skillset that one would associate with a police state -- He has files on literally every person on earth, he keeps black mail, he has worldwide surveillance, he can hack into and disable just about any persons electronics -- Not to mention he has butt loads of disposable income.
That being said, in a story where the Justice League starts to enforce peace, has batman ever been the dictator to another leaguer's freedom fighter?
