Batman: One Bad Day - Two Face #1 confirms the nature of Batman and Two-Face's complex relationship, revealing that the two men think of each other as both enemies and friends.
The one-shot revolves around Two-Face seemingly going straight and planning an extravagant birthday celebration for his estranged father, Harvey Dent Sr. After receiving a threat in the mail indicating that his father might be in danger, the younger Harvey Dent contacts Batman, who goes out of his way to monitor the party despite his misgivings about the entire situation.
In the story's finale, Two-Face proves Batman's suspicions correct by attacking his father with a poison that eats away at the facial nerves of Harvey Dent Sr., leaving him just as scarred as his son. The shock causes Dent Sr. to take his own life, an eventuality that Harvey predicted.
The Nature of Batman And Two-Face's Relationship
After confronting Two-Face in a cell and asking him about his motive, Batman learns that Harvey Dent hated his father's incessant drive for a perfect public persona and wanted to reveal the ugliness behind the man who raised him for all to see. Inviting Batman as one of his key witnesses at the party was part of this plan since, despite their differences, Two-Face still remembers the days when he worked alongside a young Dark Knight to tackle crime in Gotham City. The story ends with both men leaving each other, ruminating on the dual nature of their relationship, which t is mirrored by the two sides of Harvey's signature coin.
Two-Face remains one of the few villains in Batman's rogues' gallery who once worked on the side of good. In the past, Two-Face has been known to occasionally return to this behavior depending on the condition of his psyche. The relationship between the former Gotham District Attorney and the Dark Knight was cemented in Batman: Year One, Batman: The Long Halloween and similar stories showing the pair teaming up to fight corruption. Following the accident that scarred Harvey's face and transformed him into a criminal, the pair have still worked together on odd occasions, notably in the "Hush" storyline, where Two-Face saved Batman during his fight with Tommy Elliot.
