Like her brother, Claire Clover was a fan of Batman, after her family were saved from a mugging by the vigilante. Hoping to help him in return for his deeds, the two bought experimental treatment that granted them similar powers to Superman. However, whilst using them, they would draw off their life span, meaning they could only live for two years with similar powers as the man of steel or an hour with the powers of a god. After undergoing the therapy, they began operating as superheroes under the aliases of "Gotham" and "Gotham Girl".
I am GothamEdit
Claire first met Batman when she and Hank, as their superhero identities, saved both him and a plane from crashing into the Gotham bay. Taken under the wing by the Dark Knight, they assisted him in a battle with Solomon Grundy, and the investigation of the confession and suicide of a man in the commissioner's office. After a month of operating and assisting in saving civilians off a falling bridge, they were drawn to an explosion within the city and were confronted by Professor Strange and Psycho Pirate.
Manipulating their feelings, Pirate made the two afraid, causing Hank to kill twenty-three of the criminals' followers and Claire to be paralyzed with fear. The surviving member would later kill their parents after discovering their identities. Taken to the Batcave to recuperate and inspired by a conversation between her and Duke Thomas, Claire would join Batman and the entire Justice League to battle an insane Hank, during which he died from overusing his powers.
The following week, Claire suffered a similar effect to her brother, talking herself as if she was conversing with him whilst continuing to operate as Gotham Girl. During this time, she battled some of Batman's lesser known enemies like Colonel Blimp, Captain Stingaree and Kite Man. Confronting her on a rooftop, Batman revealed his identity to her and offered her help dealing with the trauma. Claire accepted, breaking down in the vigilante's arms as she admitted how much she missed her brother.
Breaking the Bat Edit
Due to her brother's death, Gotham Girl was able to be manipulated by Psycho Pirate into joining Bane. Bane was aiming to destroy Batman on a personal level and Psycho Pirate used his empath powers to push her to Bane's side.
