Harvey Dent is district attorney for Gotham City. He, along with his twin sister Jessica Dent, were friends with young Bruce Wayne, though Harvey had a rather antagonistic relationship with Bruce, taunting him about his Arkham family heritage. After taking office as district attorney, he was known for investigating Mayor Oswald Cobblepot due to rumors of his illicit activities. [1]

He is murdered by former Cobblepot henchman Sal Maroni during a prison riot engineered by the Riddler, having a molotov cocktail smashed into his face after being stabbed in the back with a knife. Before he dies, his sister Jessica puts the left side of her own face onto his, burning her.[2]
