Two-Face (The Dark Knight)

Harvey Dent (later known as Harvey Two-Face or simply Two-Face) was the tritagonist turned secondary antagonist of the 2008 epic superhero film The Dark Knight, and is a mentioned character in the 2012 epic superhero film The Dark Knight Rises.

He was the supreme D.A. of Gotham and vigilante, and he was also partner of both Gordon and both of Batman but after the building that he was held as host

age exploded and burned half of his face badly, he turned into a scarred deformed chaotic madman and into a fake collaborator of the Joker.

He was portrayed by Aaron Eckhart as his first his role as a villain in his career.

Before Two-Face
Two-Face started out as Harvey Dent, Gotham City's newly-elected District Attorney and "White Knight," and friend of Bruce Wayne (Batman). The Joker, knew Batman's connection to Dent and Rachel Dawes, his fiancée; kidnapped them both and strapped them to two time bombs. Joker told Batman their locations, but gave him only enough time to save only one. Batman chose Rachel, but when he got there, he found Dent instead.

Transformation
Dent got rescued (against his wishes, as he wanted his fiancée saved) and Rachel burst into flames, and died immediately in the explosion. The left half of Dent's face got burned. Angry, the former D.A. took up the name "Two-Face" and wanted revenge on those whom he believed were responsible for Rachel's death: the Joker, Gordon, and Batman. The Joker convinced Two-Face that he was just acting on impulse before he provided him with a Smith and Wesson 64 fully loaded with ammunition, to which he flipped his newly burnt coin for his life. The coin came up on the clean side, so the Joker lived. Two-Face then found Wuertz who was one of the corrupt police officers involved. The coin then landed on the burnt side and Two-Face shot and killed Wuertz. He then confronted mobster Sal Maroni who told him that Ramirez was another corrupt officer who was involved. Two-Face then flipped the coin which landed good heads for Maroni, but bad heads for the driver whom Two-Face then shot and killed, which caused the car to tumble and presumably killed Maroni as well. Finally, Two-Face then confronted Ramirez who pleaded that she needed the money for her mother who was in the hospital. The coin came up good heads and Two-Face instead knocked Ramirez unconscious. Two-Face then captured Gordon's wife, daughter and son, and called Gordon to have him meet him "where his (Two-Face) family died" (the building where Rachel died).

Death
Two-Face then Gordon there, where he planned to judge Gordon's son. At the time Gordon was trying to risk his life after unsuccessfully pleading for his family's lives, Batman showed up fast and joined Gordon in asking Two-Face to spare Gordon and his family. Having been manipulated by the Joker, Two-Face's hatred for the Joker is gone and instead blames Gordon. Batman asserted that Two-Face should point the gun only at those who were responsible. Agreeing, Two-Face promptly shot Batman through the stomach when the coin landed on bad heads. Then, assuming this has killed Batman, he spares himself when the coin came up on good heads. After he decided to continue judging Gordon's son, Two-Face flipped the coin. Before he could decide the fate of Gordon's son, Batman, who was wearing body armor and is unharmed, tackles Dent off the ledge of the roof to his death when breaking his neck.

Legacy
Batman and Gordon agreed to cover up Dent's villainous acts by putting the blame on Batman, due to fear of the public losing hope if they found out what happened. Dent's death was used to create a new law dubbed the "Dent Act," whereby anyone with criminal affiliations would be convicted without trial or parole. When Bane found out about the truth about Dent, he used it in his crusade against Gotham. After the battles were over, the Dent Act was repealed and all of Dent's accolades were erased from the records.

Trivia

 * His alias "Harvey Two-Face" was never adopted by himself, it was only mentioned by Gordon.
 * Despite being the secondary antagonist, Two-Face is the final villain that Batman faces in the film.
 * Dent and Talia al Ghul were the most personal villains for Bruce Wayne in The Dark Knight Trilogy. Dent represented the idealistic verion of Batman, which doesn't need a cape and gadgets to cleanse the city from the criminals. At the same time, Talia was an anti-Batman. Basically she in The Dark Knight Rises is Bruce Wayne inBatman Begins if he drawned down in his desire to avenge his parents death and agreed to lead the League of Shadows's crusade against Gotham. Ultimately, both Talia and Dent are the only villains which were killed by Batman himself.
