Biography
Oswald Cobblepot was the father of Waylon Cobblepot. Disgusted by Waylon's appearance, Oswald confined the infant to a cage and later threw him to the sewers, killing his wife, Esther, when she tried to stop him.

At some point, Oswald had a second wife and a second son, Chip Cobblepot. He also killed Selina Kyle's parents because they threatened his business.

Oswald proposed to build a power plant to supply Gotham with energy but was opposed by the mayor. During Oswald's speech, the city was attacked by what remained by the Joker gang. Despite Batman's efforts to save Oswald, he was kidnapped and taken to the sewers to meet Waylon, now known as Killer Croc and the new leader of the former Joker gang. Oswald offered to help Croc return to the surface in exchange for helping him become mayor. Croc accepted but warned that he had evidence of Oswald's corporate crimes in case he tried to double cross him.

Batman investigated Oswald's connection with Killer Croc. During a meeting with Oswald, Bruce met Selina Kyle, in a disguise to steal from Oswald.

In order to run for mayor, Oswald discredited the current mayor by having Killer Croc wreck havoc on Gotham. Batman intervened and met Catwoman who was trying to sabotage one of Oswald's businesses.

Oswald had Killer Croc frame Batman for killing Gotham's ice princess and sabotage the Batmobile so he could have it rampage through Gotham. During the rampage, Batman recorded disparaging remarks Oswald made about the people of Gotham and played it during his next speech, destroying his image and preventing him from being elected as mayor. Oswald decided to severe ties with Killer Croc by sending Gotham police to kill him. He later hosted a charity ball, hoping to rebuild broken bridge for the next election. It was during this ball that Bruce and Selina were able to work out each other's identities as Batman and Catwoman. Croc attacked the event and revealed his plan to abduct and kill all of Gotham's firstborn sons in revenge for Oswald's abandonment of him. Croc intend to abduct Chip but Oswald gave himself in his stead.

Oswald escaped but was confronted by Catwoman. Batman tried to stop Catwoman from killing Oswald but Oswald shot him before shooting Catwoman multiple times. Catwoman kicked Oswald into the Gotham where he was eaten by Killer Croc.
