Alfred Thaddeus Crane Pennyworth is a fictional character appearing in American comic books published by DC Comics, most commonly in association with the superhero Batman. Pennyworth is depicted as Bruce Wayne's loyal and tireless butler, legal guardian, best friend, aide-de-camp, and surrogate father figure following the murders of Thomas and Martha Wayne. As a British ex-Special Operations Executive operative of honor and ethics with connections within the intelligence community, he has been called "Batman's batman". He also provides comic relief with his sarcastic and cynical attitude which often adds humor to dialogue with Batman.
Alfred appears as a main character in Geoff Johns' and Gary Frank's Batman: Earth One. In this incarnation, Alfred was a member of the Royal Marines. Alfred met Thomas Wayne during a tour of duty in the Middle East and the two became good friends. During a battle, Alfred saved Thomas' life but lost his right leg in the process. It is also implied that both he and Thomas are keeping a traumatic secret. Discharged back to his home in London, Alfred received a gift from Thomas in the form of a very expensive prosthetic leg. He later traveled to Gotham City to visit his friend and found himself arriving on the night of a campaign party for Thomas' bid at the mayoral office. Afraid for his friend after hearing of the death threats on his life, Alfred tried to talk Thomas out of going to the movies with his wife and son, but Thomas refused to allow threats to keep him from enjoying his weekly movie night with Martha and Bruce. Later that night, Alfred was called to the police station. Thomas and Martha had been killed by a mugger outside the theatre and Bruce had been orphaned. To Alfred's shock, he discovered that Thomas and Martha had named him Bruce's legal guardian some time ago. Unsure of himself, Alfred still made it his mission to look out for Bruce as he grew up. When Bruce took on his costumed persona of Batman and began his war on crime, Alfred reluctantly took on the role of confidante and advisor, often telling Bruce to simply carry a gun instead of a belt full of untested gadgets. Alfred later saved Bruce's life by shooting Mayor Oswald Cobblepot. Though Alfred introduced himself to the eight-year-old Bruce as his butler, it is obvious he never serves as a manservant in the story otherwise as Bruce's guardian and mentor. However, he is recruited by Thomas as his family's head of security prior to Thomas and his wife's deaths. He is also a skilled martial artist, and trains Bruce the combat skills he would eventually utilize as Batman. He has a daughter living in Seoul, South Korea with her mother, where Alfred had previously worked at a security firm, implying Julia Remarque's existence in this continuity.
