Ratcatcher (comics)

The Ratcatcher (Otis Flannegan) is a character appearing in American comic books and other media published by DC Comics, primarily as an enemy of Batman. He belongs to the collective of adversaries that make up the Dark Knight's rogues gallery. Once an actual rat-catcher in Gotham City, Flannegan sank into a life of crime. Calling himself the Ratcatcher because of his special ability to communicate with and train rats, Flannegan has used his minions to plague Gotham on more than one occasion by unleashing hordes of the vermin.

A female version of the character named Cleo Cazo / Ratcatcher 2 appears in the DC Extended Universe film The Suicide Squad (2021), portrayed by Daniela Melchior. Taika Waititi portrays the first Ratcatcher, Cleo's father.

Publication history
The Ratcatcher first appeared in Detective Comics #585 (April 1988) and was created by writers Alan Grant and John Wagner, and artist Norm Breyfogle.

Fictional character biography
Otis Flannegan used to work as a rat-catcher in the Gotham City Sanitation Department who claimed he could train rats to attack before he was eventually arrested and spent ten years in Gotham State Penitentiary after stabbing a man to death in a street fight. After being released, Flannegan kidnapped the four officials responsible for his arrest and subsequent sentence and took them to his hideout in the city's sewers, where he kept them for five years. During this period, Flannegan developed his criminal alter-ego of the Ratcatcher. Wearing protective equipment and using his animal training skills, Flannegan gathered a large swarm of rats to torture and restrain his prisoners.

After five years of captivity, one of Flannegan's prisoners escaped. Though he ordered his rats to kill him, the latter reached the surface, where Batman discovered his body, followed the rats back to Flannegan, and easily defeated him upon dispersing his rats. After being re-incarcerated, he escapes his parole hearing using a flute he carved to control rats via a high-pitched frequency, only to be foiled by Dick Grayson disguised as Batman and captured again.

During the events of Infinite Crisis, Flannegan found refuge with Gotham's homeless community. When the authorities found and re-arrested him, one of the homeless men discovers he is an OMAC while attempting to help Flannegan and vaporizes him.

When DC Comics created The New 52 to reboot their comics, Flannegan was revived and makes a minor appearance in Batman Eternal.
