Mason Bridge was a Pulitzer-winning journalist who worked for the Central City Picture News. His editor-in-chief, Eric Larkin, made him watch over newbie Iris West, despite him not wanting to. He was highly intelligent as a reporter and good at reading people and situations, as he was one of the few people who were immediately aware that Dr. Harrison Wells was not as innocent as he seemed, realizing he was a sociopath and liar. He was killed by the Reverse-Flash because of his investigation of Harrison Wells.
