Sidney later earned the title "the man who killed Batman."Eddie and the other mobsters celebrated Sidney's victory over Batman at a bar. For a short time, Sidney liked his title and fame and many criminals said that he's the toughest guy in Gotham. Though, there were some that wanted Sidney's title and challenged Sidney. Although Debris was actually a weak man, he attempted to flee his opponents but it caused a bar fight between his allies and those who challenged. The bar fight was brought to a halt by the police and everyone involved was arrested including Sidney. Debris was later bailed out by Harleen Quinzel in disguise as a lawyer. She later presented Sidney to The Joker. The Joker doesn't believe Sidney killed Batman so they pulled a robbery to prove it. However, Batman didn't show up. The Joker was angry that the honor of killing Batman was stolen by a small time criminal. In response, he locked Sidney into a coffin and had him rolling into a vat of acid.

However, Batman who turns out to survive the explosion defeated and stopped Thorne. Batman revealed to Debris that he pulled away from the explosion at the last second. Sidney realized it was Batman who saved him from The Joker's wrath. Batman grabbed Debris and told him he was an accomplice in the drug deal therefore needs to go to jail.
