Ratcatcher

Once employed as an actual ratcatcher in Gotham City, Otis Flannegan soon started using his strange ability--an affinity with and the ability to control rats--to stage a variety of crimes. Eventually, his control over the vermin grew until he threatened Gotham with a veritable army of rodents. Incarcerated many times at Blackgate Prison, he can cause as much damage behind bars as without, using his loyal, trained, pets to relay messages and transport materials inside the maze of ventilation ducts that wind throughout the giant prison.

Character History
A one onetime actual rat catcher in Gotham City, Otis Flannegan sank into a life of crime like he sank in the sewers he was so accustomed to working in. Though he's been imprisoned numerous times in his career (he's a regular in Blackgate prison) for assault, kidnapping, and robbery (the regular line-up of Gotham's Rogues), Flannegan calls himself The Ratcatcher because of a special trait he was gifted: the ability to communicate with and train rats. While the small furry army at his control is, at first glance, a rather odd and seemingly useless gift, The Ratcatcher has used his minions to plague Gotham on more than one occasion. Imagine, if you will, a single rat. Small, weak, but strangely intelligent (just like Flannegan, who possesses an odd similarity in look to the small creatures.) But, imagine multiplying this single biting rodent by tens of thousands; a seemingly unstoppable sea of rats able to attack on a near biblical scale, all under The Ratcatcher’s control. In prison, Flannegan is able to communicate within the prison with other prisoners, and is able to smuggle items in and out, with the help of his small friends.

The Ratcatcher later made an appearance among several other villains (Including Killer Croc, Hugo Strange, KGBeast, Crazy Quilt, Wrath II, Tobias Whale, and the Ten-Eyed Man) on the cover of Formerly Known As the Justice League # 4.

Even though Flannegan isn't the most devious or most powerful of Batman's rogues gallery, nor is he considered as insane, his gas mask and vermin control gear (due to the environment he works in), has allowed him to be a worthy villain among the criminal underworld. He also had a friendship with the minor rouge Magpie who counts him as a good friend and ally thought he is considerably older then her.

When Infinite Crisis began, the Ratcatcher was being protected by, in addition to his rat friends, the homeless community. When he was discovered and being taken away, one of the homeless attempted to aid Flannegan, but was easily knocked aside by the arresting officers. The man turned out to be an OMAC in hiding, and the injury apparently initiated its release. The OMAC identified the Ratcatcher as a gamma level threat and vaporized him.

Powers and abilities
The Ratcatcher possessed thorough knowledge of Gotham's sewer system and Blackgate Prison's layout. He also possessed the ability to communicate with and train all rats. The Ratcatcher also notably overvalued rodent life, especially in comparison to human life.

Batman Beyond
A character similar to Otis Flannegan named Patrick appeared in the Batman Beyond episode "Rats", and was portrayed by Taran Noah Smith. He is a deformed runaway teen who has the power to communicate with rats.

Psychological Profile
The Ratcatcher

Real Name: Otis Flannegan

TELL MAINTENANCE TO INCREASE RAT POISON AROUND CELL.

Psychological Profile: Suffering from acute anthropomorphic delusions, Flannegan is so convinced that he can control rats, that he has persuaded many of Arkham's inmates, orderlies, guards, and even other doctors that he commands this fantastical ability. Personally, I don’t consider "evidence" provided by the Batman to be convincing of anything, and find it much more likely that Flannegan has manifested a unique variation of a Messiah complex.

Additional Notes

I'm hesitant to administer aggressive treatment before first doing a full write-up on his condition; it could be an easy way to get published and procure naming rights to a newly documented disorder.

If only there weren't so many odious vermin constantly swarming in his cell.

Batman: Arkham City


In the highly anticipated sequel to Batman: Arkham Asylum, an old pest control poster from his days as an actual ratcatcher also appears in a recent preview of the game. Rumors of him in the game, are yet to be proven.
