A fourteen-year-old prodigy who was raised as a weapon
Gotham's best man, decided by a coin
Editorial estimates on a 0–100 scale, calibrated against every other character in the index. Not official canon.
Harvey Dent was the district attorney who was going to clean up Gotham legally, which is the one thing Batman cannot do. After acid destroys half his face he outsources every decision to a scarred silver dollar, and the tragedy is precise: a man who devoted his life to judgment now refuses to make any. He is the city's failure in a two-tone suit.
He was on the inside of Gotham's justice system and knows every weakness in it.
The coin. If you control the flip, you control him.
The man who was going to fix the city legally, reduced to outsourcing every decision to a coin. It is the cleanest tragedy in superhero comics.
Gotham's best man reduced to a coin toss. It is the cleanest tragedy in superhero comics and it never needs a rewrite.
