Hamilton Hill was the corrupted Mayor of Gotham city. Holding ties to the Falcone Crime Syndicate, he was both an ally of its leader, Carmine Falcone, and Gotham base billionaires Thomas and Martha Wayne.
Biography
Hamilton Hill became Mayor of Gotham years before Thomas and Martha Wayne's murder in Crime Alley. He forge an alliance with the two and crime boss Carmine Falcone, running the politics whilst Falcone handled many of their operations and the Waynes legitimized their money. Though challenged to his place as Mayor, Hamilton's opposition would frequently disappear, under suspicious circumstances. One of his previous rivals included Theodore Cobblepot, who's death he staged as a suicide to detract attention.
With Thomas, Hamilton was responsible for convicting people who refused their offers to Arkham, sending them insane with a psychogenic chemical. One of them was Esther Cobblepot, the last remaining "of age" Cobblepot, who refused to sell land that later became the site of Wayne Tower.
Eventually, Martha saw that Thomas was going too far and threatened to expose his crimes, before he did too much harm, worrying Hill. He hired one of Falcone's hitmen Joe Chill to assassinate Thomas and Martha and make it look like a mugging gone wrong. Chill did so as they and their son Bruce returned home from a movie showing at the Monarch Theater. However, Chill was caught, but Hamilton, and possibly Falcone, arranged for him to be murdered in prison.
Nearly twenty years after that event, Hamilton was approached by Theodore and Esther's son, Oswald, who wanted to exposed Gotham's corruption and remove those who were from power. Either through blackmail or a willing alliance, Hamilton gave him evidence to prove the Wayne's ties to corruption. He also began compiling data to incriminate Carmine Falcone, either to hand over to Oswald or help boast his campaign as Mayor. Unknown to him, Penguin also planned to kill him, once he had served his purpose. At the same time, Hamilton was challenged for his seat of Mayor by District Attorney Harvey Dent.
Episode One: Realm of Shadows
At the beginning of the episode, Hill's office was attacked by the Children of Arkham and Catwoman, both of whom attempted to break into his vault and steal data he had compiled on Falcone. However, the latter was successful whilst the mercenaries were caught by Batman. The next day, Hill authorized a police warrant to search Wayne Manor and collect documents related to Wayne Enterprises. This was either at the behest of Oswald or a smear tactic to ruin Dent's campaign.
Episode Two: Children of Arkham
Hill later called one of Penguin's men, demanding that he was let loose and that the debate was not attacked. Later, Bruce Wayne, following a confrontation with this man at the Stacked Deck Bar, came into position of this phone and heard a recorded call from Hill to this henchman. Deciding to confront Hill, he can choose to go either as himself or Batman.
Managing to charm Hill's secretary into letting him in, Bruce meets with Hill, who is practicing for that night's debate. When Hill questions Bruce on why he is here, the latter plays the recorded call made that day. Hill agrees to tell Bruce, if he promises to stop funding Dent's campaign. If Bruce agrees to, Hill reveals how he, Thomas and Falcone took control of the city and gained property from those who disagreed. He also shares information on why Penguin is attacking Gotha. Despite Bruce's warnings, Hill claims that he is still in control. Before he leaves, Hill gives Bruce his father's cufflinks, hoping that the two will work together in the future.
Whilst on the call with his secretary, the power in Hill's office was suddenly cut. As he called out to her, Batman made his presence aware to Hill. The vigilante questioned Hill on his connection to the Penguin, even playing a recording on the call he had made. Hill tried to rebuke the conversation onto Wayne and, whilst he was distracted, called for security. Batman responded by dangling Hill from the balcony, demanding that Hill really told him the truth. He complied, telling him about Thomas Wayne's unlawful commission of Gotham citizens to Arkham Asylum to gain control of their land and wealth. Satisfied with what he had heard, Batman let Hill go and left as City Hall security guards appeared.
