Shit since they throwing out budgets pass me 1 I always had a origin story for a black joker.. Not necessarily crazy but more of a product of his enviroment... He grew up in the poorest of the poorest of gotham.. Pretty much due to certain events killed at an early age in self defense.. He hated criminals and formed a group at an early age to eliminate, control .policing his area ..extorting drugdealers, protecting hookers, giving back to the community that Gotham forgot about.. Hes part Omar from the wire, part vigilante, part Nino brown... He's hated by the mafia cause he represents defiance, order in the black community, and he won't allow them to operate in the black community unless he gets pc and overseer all their operations..of course that creates friction and they want his head for it.. They try to order a hit on him using paid police officers.. He defends himself...Batman happens to interfere during this ordeal without knowing the history.. Injuring the joker severely... His skin gets discolored, his mouth is damaged(explains his scars)..gets arrested... Attempts to commit suicide...meets Harley when he gets physiological evaluated.. Gets broken out thanks to the scarecrow invasion, and wants revenge on bats..that's where dark knight begins..revenge movie..lot of stuff I left out but you get it
