Despite escaping the explosion physically unscathed, Dent suffers a crisis of conscience and a mental battle with his "Two-Face" personality. Although Batman later uncovers evidence that exonerates Dent for the murders, establishing that he was framed as revenge for his efforts against new crime boss Warren White, a.k.a. the Great White Shark, it is too late to save him. Prompted by resentment and a paranoid reaction to Batman's questioning, Dent scars half his face with nitric acid and a scalpel, becoming Two-Face once again. Blaming Batman for his return, Two-Face immediately goes on a rampage, threatening to destroy the Gotham Zoo (having retained two of every animal—including two humans) before escaping to fight Batman another day. Batman subsequently confronts White, while acknowledging that he cannot attack White, as there is no explicit evidence supporting Batman's deductions, vowing to inform Two-Face of White's actions when they next face each other.
