Origin
Edward Brannigan was a peculiar fellow but nonetheless an honest one, a history teacher as well as chemistry teacher. He had developed a fascination with all sorts of gruesome ways of killings and torture in the past, but what interested him the most was the unsolved mystery of Jack the Ripper. Attempts at solving the crime himself using modern evidence drove him made, giving him the conclusion of "I am the Ripper. " He took up a butcher's knife and brutally murdered his wife, stabbing her 47 times, then murdering all of his students. However, he immediately lost interest in this and felt great sorrow and guilt, making him turn himself into the police. In Arkham he was a very docile and good behaviored inmate which granted him access to more luxurious items. That which he treasured most, however, were books. He read all day until it was time for the lights out. One night, however, he obtained a book centered around the Jack the Ripper casefiles. He went mad once more with an insatiable bloodlust. He would escape Arkham once more and cut off parts of his face down to the bone. He would fashion an outfit consisting of a black trench coat, a top hat, and a scarf to cover his mouth. He also managed to deduce the formula of Scarecrow's fear toxin. He converted this into a gas and created fear gas bombs. He was now Jack the Ripper.
