Julia Pennyworth

Biography
The daughter of Alfred and a French Resistance fighter named Mlle Marie, Julia was brought in by Gerry Conway in Detective Comics #501 in 1981. In the New 52, Julia is a Special Reconnaissance Regiment member and first appears in Hong Kong, where while repelling down a skyscraper, she notices the Batplane and seems not too pleased with Batman's presence in the city, fearing that he might ruin everything she's planned. Julia later meets Batman and tries to fight him off, telling him she's planned to take down the crime lord known as Shen Fang, whom Batman is also after, and won't have him get in her way. Despite Batman trying to get her to stand down and work with him, she refuses, which distracts her enough to allow Fang to sneak up behind her and put a katana through the gut. Bruce is later on his way back to Gotham with Julia patched up and passed out in the back of the plane. He tells Alfred that she'll be staying with them, which Alfred is surprised to hear, questioning bringing in a "stray" but Bruce had done some digging, and despite her being one of those people who "doesn't exist," he reveals that she is not a stray but Alfred's daughter.
